[0015] (First Embodiment)
Hereinafter, an apparent temperature calculation system, an environment control system, an apparent temperature calculation method, and a program according to a first embodiment will be described with reference to some drawings. FIGS. 2 and 3 to be referred to in the following embodiment and so on are schematic drawings. The ratio of the dimensions including thicknesses, of respective constituent elements illustrated on the drawings does not always reflect their actual dimensional ratio. [0016] (1) Apparent Temperature Calculation System
A configuration of an apparent temperature calculation system 1 according to the first embodiment will be described with reference to the drawings.
[0017] As illustrated in FIG. 1, the apparent temperature calculation system 1 according to the first embodiment includes an acquiring unit 11, a processing unit 12, an equipment controller 13, a storage unit 14 and a reporting controller 15.
[0018] The apparent temperature calculation system 1 is applied for obtaining an apparent temperature distribution of domestic animals 9 (livestock; see FIG. 3) in a space 7 (see FIG. 2) of a building 6 (see FIG. 2) where the domestic animals 9 are present. Many domestic animals 9 are present in the space 7 (see FIG. 3). [0019] (2) Building
The building 6 to which the apparent temperature calculation system 1 is applied will be described with reference to the drawings. The building 6 shown in FIG. 2 is only one example. The building 6 to which the apparent temperature calculation system 1 is applied is not limited to the example of FIG. 2.
[0020] As illustrated in FIG. 2, the building 6 includes a building body 61 with an approximately rectangular parallelepiped shape, for example. Also, the building 6 has the space 7.
[0021] In the example of FIG. 2, the building 6 is a livestock barn where the domestic animals 9 are reared. When the building 6 is the livestock barn, the building body 61 corresponds to a main body of the livestock barn. Many domestic animals 9 are reared in the space 7 of the building 6 (see FIG. 3). The livestock barn may be a chicken house where chickens are reared, for example. However, the livestock barn is not limited to the chicken house. The livestock barn may be a pigpen where pigs as the domestic animals 9 are reared. Alternatively, the livestock barn may be a cow barn where cows as the domestic animals 9 are reared. [0022] The building body 61 includes two first sidewalls 62 and 63, and two second sidewalls 64 and 65.
5

[0023] The two first sidewalls 62 and 63 have, for example, rectangular shapes and are disposed along a longitudinal direction D1 of the building 6. The two first sidewalls 62 and 63 are arranged to face each other via the space 7 in a short-length direction D2 of the building 6. [0024] The two second sidewalls 64 and 65 have, for example, rectangular shapes and are disposed along the short-length direction D2 of the building 6. The two second sidewalls 64 and 65 are arranged to face each other via the space 7 in the longitudinal direction D1 of the building 6.
[0025] The space 7 is surrounded by the building body 61. More specifically, the space 7 is surrounded by the two first sidewalls 62 and 63 and the two second sidewalls 64 and 65 in a planar view when viewed in a height direction D3 of the building 6.
[0026] The building 6 further includes a plurality of air supply ports 66 (two air supply ports in the example of the drawings) and an air exhaust port 67. The air is supplied from the outside of the building 6 to the space 7 through each of the plurality of air supply ports 66. Also, the air is exhausted from the space 7 to the outside of the building 6 through the air exhaust port 67. [0027] The plurality of air supply ports 66 (air supply ports 661 and 662) are disposed at lower ends of the first sidewalls 62 and 63 along the longitudinal direction D1 of the building 6. More specifically, one air supply port 661 is disposed at a lower end of the first sidewall 62 on a first end side (the side close to the second sidewall 64) of the building 6 in the longitudinal direction D1. The other air supply port 662 is disposed at a lower end of the first sidewall 63 on a first end side (the side close to the second sidewall 64) of the building 6 in the longitudinal direction D1. The air supply ports 661 and 662 are arranged to face each other in the short-length direction D2 of the building 6.
[0028] The air exhaust port 67 is disposed on a second end side (the side close to the second sidewall 65) of the building 6 in the longitudinal direction D1. The air exhaust port 67 is arranged near a center of the second sidewall 65 in the height direction D3. Alternatively, the air exhaust port 67 may be arranged near an upper end of the second sidewall 65. [0029] Note that, the number of air supply ports 66 is not limited to two, but may be one, three or more. In short, the number of air supply ports 66 may be one or more. The number of air exhaust ports 67 is not limited to one, but may be two or more. In short, the number of air exhaust ports 67 may be one or more. [0030] (3) Environment Control System
As illustrated in FIG. 1, an environment control system 2 according to the first embodiment includes the apparent temperature calculation system 1, a plurality of measuring devices 3 (two measuring devices in the example of the drawings), a control device 4 and an
6

environmental equipment 5. The environment control system 2 according to the first embodiment further includes a detection device 33 and a reporting device 21. [0031] (3.1) Measuring Device
As illustrated in FIG. 2, the plurality of measuring devices 3 are configured to measure environmental information representing an environment of the space 7. The plurality of measuring devices 3 measure, as the environmental information, physical quantities relating to environments of representative points 71 and 72 in the space 7. The plurality of measuring devices 3 output the environmental information measured to the apparent temperature calculation system 1.
[0032] The plurality of measuring devices 3 include a measuring device 31 of measuring the physical quantity relating to the environment of the representative point 71 in the space 7 and a measuring device 32 of measuring the physical quantity relating to the environment of the representative point 72 in the space 7. The representative point 71 in the space 7 is located on an upwind side in the space 7. The representative point 71 is at a position closer to the air supply port 66 than the air exhaust port 67 in the longitudinal direction D1 of the building 6. A distance between the representative point 71 and the air supply port 66 in the longitudinal direction D1 is shorter than a distance between the representative point 71 and the air exhaust port 67 in the longitudinal direction D1. The representative point 72 in the space 7 is located on a downwind side in the space 7. The representative point 72 is at a position closer to the air exhaust port 67 than the air supply port 66 in the longitudinal direction D1 of the building 6. A distance between the representative point 72 and the air exhaust port 67 in the longitudinal direction D1 is shorter than a distance between the representative point 72 and the air supply port 66 in the longitudinal direction D1.
[0033] Examples of the physical quantity relating to the environment of the space 7 include a temperature, a humidity, a wind velocity, a carbon dioxide concentration, an ammonia concentration and a dust concentration. For example, when the temperature is measured, each measuring device 3 may include a temperature sensor. When the humidity is measured, each measuring device 3 may include a humidity sensor. When the wind velocity is measured, each measuring device 3 may include a wind velocity sensor. Each measuring device 3 is not limited to a configuration of measuring all the temperature, the humidity, the wind velocity, the carbon dioxide concentration, the ammonia concentration and the dust concentration, as the physical quantity relating to the environment of the space 7. Each measuring device 3 may measure at least one selected from the temperature, the humidity, the wind velocity, the carbon dioxide concentration, the ammonia concentration and the dust concentration, as the physical quantity
7

relating to the environment of the space 7. That is to say, each measuring device 3 may include
at least one sensor.
[0034] The dust concentration means an amount of dust included in a space per unit volume.
A large amount of dust tends to be generated in the space 7 where the domestic animals 9 are
present. The dust may affect a formation of body tissues of domestic animals 9. Accordingly,
the dust concentration in the space 7 is preferably measured.
[0035] (3.2) Control Device
As illustrated in FIGS. 1 and 2, the control device 4 outputs a control signal to the environmental equipment 5 to control the environmental equipment 5. More specifically, the control device 4 acquires control contents (e.g., control parameters) for the environmental equipment 5 from the apparent temperature calculation system 1. The control device 4 outputs, to the environmental equipment 5, the control signal including the control contents acquired from the apparent temperature calculation system 1 to control the environmental equipment 5. [0036] (3.3) Environmental Equipment
The environmental equipment 5 illustrated in FIG. 1 is equipment for controlling the environment of the space 7 (see FIG. 2). As illustrated in FIG. 1, the environmental equipment 5 includes a plurality of opening/closing windows 51 (two opening/closing windows in the example of the drawings) and a plurality of ventilation fans 52 (three ventilation fans in the example of the drawings). The environmental equipment 5 controls the environment of the space 7 according to the control of the control device 4. [0037] (3.3.1) Opening/closing Window
As illustrated in FIG. 2, the plurality of opening/closing windows 51 are disposed at the air supply ports 66 of the building 6. More specifically, one opening/closing window 511 of the plurality of opening/closing windows 51 (511, 512) is disposed at the air supply port 661 of the first sidewall 62, and the other opening/closing window 512 is disposed at the air supply port 662 of the first sidewall 63.
[0038] The plurality of opening/closing windows 51 are referred to as so-call tunnel doors, and configured to turn vertically to be opened or closed. When the opening/closing windows 51 are opened, air can be made enter the space 7 from the outside of the building 6 through the air supply ports 66. [0039] (3.3.2) Ventilation Fan
As illustrated in FIG. 2, the plurality of ventilation fans 52 are disposed at the air exhaust port 67. More specifically, the plurality of ventilation fans 52 are disposed on the opposite side to the plurality of opening/closing windows 51 in the longitudinal direction D1.
8

That is to say, the plurality of ventilation fans 52 are disposed on the second sidewall 65. [0040] The plurality of ventilation fans 52 are arranged side by side in a row in the short-length direction D2. More specifically, ventilation fans 521, 522 and 523 are arranged in that order from the first sidewall 63 in the short-length direction D2.
[0041] The plurality of ventilation fans 52 exhaust air in the space 7 of the building 6 to the outside of the building 6. More specifically, the plurality of ventilation fans 52 are disposed so as to exhaust the air in the space 7 in the almost same direction. Accordingly, the air in the space 7 can be sucked at a position on an air exhaust side (downwind) in the space 7 and exhausted to the outside of the building 6. [0042] (3.4) Detection Device
The detection device 33 illustrated in FIG. 1 is configured to detect the presence of the domestic animal 9 (see FIG. 3). The detection device 33 includes, for example, an image capture device of capturing an image of the space 7, and has a function of extracting the domestic animal 9 from the image captured. Alternatively, the detection device 33 may include, for example, an infrared sensor, and have a function of receiving infrared rays emitted from the domestic animal 9. The detection device 33 can detect, by having the above function, a region where the domestic animal 9 is present, of the space 7, and a region where many domestic animals 9 are present. The detection device 33 outputs, as biological detection information, such a detection result to the apparent temperature calculation system 1. [0043] (3.5) Reporting Device
The reporting device 21 illustrated in FIG. 1 reports the domestic animal 9 (see FIG. 3) present in a space under an abnormal environment, and a position of the domestic animal 9 present in the space under the abnormal environment. The reporting device 21 reports information, which should be reported, according to the control of the apparent temperature calculation system 1.
[0044] The reporting device 21 includes, for example, a display having a display function of displaying prescribed information. When including the display, the reporting device 21 can visually report the domestic animal 9 present in the space under the abnormal environment, and the position of the domestic animal 9 present in the space under the abnormal environment. [0045] The reporting device 21 includes, for example, a loudspeaker having a voice output function of outputting prescribed information in voice. When including the loudspeaker, the reporting device 21 can acoustically report the domestic animal 9 present in the space under the abnormal environment, and the position of the domestic animal 9 present in the space under the abnormal environment.

[0046] (4) Each Component of Apparent Temperature Calculation System
Hereinafter, each component of the apparent temperature calculation system 1 according to the first embodiment will be described with reference to the drawings. [0047] (4.1) Acquiring Unit
As illustrated in FIG. 1, the acquiring unit 11 is configured to acquire measurement results of the measuring devices 3, as the environmental information of the space 7 (see FIG. 2) where the domestic animals 9 (see FIG. 3) are present, from the measuring devices 3. More specifically, the acquiring unit 11 acquires the environmental information representing the environments at two representative points 71 and 72 (see FIG. 2) in the space 7 by wire communication or wireless communication. The environmental information includes information about at least one selected from the temperature, the humidity, the wind velocity, the carbon dioxide concentration, the ammonia concentration and the dust concentration. [0048] (4.2) Processing Unit
As illustrated in FIG. 1, the processing unit 12 includes a first calculation unit 121 and a second calculation unit 122. The processing unit 12 is configured as one function of a computer processor. [0049] (4.2.1) First Calculation Unit
The first calculation unit 121 illustrated in FIG. 1 is configured to calculate an environmental distribution of the space 7 (see FIG. 2), based on the environmental information of the space 7. In the first embodiment, the environmental information includes information representing the environments at the plurality of the representative points 71 and 72 (see FIG. 2) in the space 7. More specifically, the two representative points 71 and 72 are present in the space 7. The two representative points 71 and 72 are at a position on the upwind side in the space 7 and a position on the downwind side in the space 7, respectively. More specifically, as illustrated in FIG. 2, the representative point 71 is at the position on the upwind side in the space 7, and the representative point 72 is at the position on the downwind side in the space 7. [0050] The first calculation unit 121 illustrated in FIG. 1 calculates the environmental distribution of the space 7 based on the environmental information at the representative points 71 and 72 in consideration of a layout of the space 7 of the building 6 and the positions of the representative points 71 and 72 in the space 7. For example, a function in consideration of the layout of the space 7 and the positions of the representative points 71 and 72 in the space 7 is previously prepared. The first calculation unit 121 calculates the environmental distribution of the space 7 by inputting the environmental information at the representative points 71 and 72 into the above function. The above function is previously stored in the storage unit 14. The
10

calculation method for the environmental distribution by the first calculation unit 121 is not limited to the means using the function as above, but may be another means. [0051] (4.2.2) Second Calculation Unit
The second calculation unit 122 illustrated in FIG. 1 is configured to calculate the apparent temperature distribution of the domestic animal 9, based on the environmental distribution calculated by the first calculation unit 121 and an arithmetic model. [0052] The apparent temperature distribution of the domestic animal 9 means a distribution relating to temperature which would be perceived (felt) by the domestic animal 9 in the space 7. It is not easy to measure the actual apparent temperature of the domestic animal 9. When many domestic animals 9 are present in the space 7, it is further difficult to measure the actual apparent temperatures of the domestic animals 9 individually (i.e., an individual domestic animal). Also, in order to measure an environmental temperature in a region where the domestic animal 9 is present, the temperature sensors are needed to be installed at many positions in the space 7. [0053] Furthermore, the domestic animals 9 may have the different heights, as they grow. Accordingly, if the apparent temperature distribution is made as a two-dimensional area viewed from above the building 6, it is not sufficient. Thus, the second calculation unit 122 is configured to calculate, as a three-dimensional distribution including not only a planar direction but also the height direction D3, the apparent temperature distribution of the domestic animal 9. The sizes of the domestic animals 9 at each stage of growth can be accordingly considered. Consequently, the present apparent temperature calculation system can improve the accuracy in the apparent temperature distribution of the domestic animal 9. [0054] (4.2.3) Application of Processing Unit
The second calculation unit 122 of the processing unit 12 illustrated in FIG. 1 is configured to execute a calculation, using a classifier to which machine learning is performed. Note that, only the second calculation unit 122 is not limited to be configured to execute the calculation, using the classifier to which machine learning is performed. Only the first calculation unit 121 may be configured to execute the calculation, using the classifier to which machine learning is performed. Alternatively, both the first calculation unit 121 and the second calculation unit 122 may be configured to execute the calculation, using the classifier to which machine learning is performed. In short, at least one of the first calculation unit 121 and the second calculation unit 122 is preferably configured to execute the calculation, using the classifier to which machine learning is performed.
[0055] In the first embodiment, the first calculation unit 121 and the second calculation unit 122 illustrated in FIG. 1 execute the calculation in consideration of an air flow in the space 7 (see
11

FIG. 2). The air flow in the space 7 is based on a layout of the building 6 (see FIG. 2), opening states of the opening/closing windows 51 (see FIG. 2), ventilation capacities of the ventilation fans 52 (see FIG. 2), a wind velocity on the upwind side and a wind velocity on the downwind side. The information relating to the air flow in the space 7 is previously stored in the storage unit 14. Note that, both the first calculation unit 121 and the second calculation unit 122 are not limited to be configured to execute the calculation in consideration of the air flow in the space 7. Only the first calculation unit 121 may be configured to execute the calculation in consideration of the air flow in the space 7. Alternatively, only the second calculation unit 122 may be configured to execute the calculation in consideration of the air flow in the space 7. In short, at least one of the first calculation unit 121 and the second calculation unit 122 is preferably configured to execute the calculation in consideration of the air flow in the space 7. [0056] The second calculation unit 122 of the processing unit 12 illustrated in FIG. 1 is not limited to be configured to calculate the apparent temperature distribution of the domestic animal 9 over the whole of the space 7. The second calculation unit 122 may be configured to calculate the apparent temperature distribution of the domestic animal 9 about only a part of the space 7. For example, the second calculation unit 122 calculates the apparent temperature distribution of the domestic animal 9 in only a region where the domestic animal(s) 9 is present, of the space 7. The second calculation unit 122 calculates the apparent temperature distribution of the domestic animal 9, based on the biological detection information and the environmental distribution of the space 7. The biological detection information is information representing the presence of the domestic animal 9 in the space 7. The second calculation unit 122 acquires the biological detection information from the detection device 33.
[0057] For example, the second calculation unit 122 calculates the apparent temperature distribution of the domestic animal 9 for only regions A1 and A4 where many domestic animals 9 are present, of the space 7 in the example of FIG. 3. That is to say, the apparent temperature distribution for regions A2 and A3 is not calculated.
[0058] In addition, the processing unit 12 illustrated in FIG. 1 may have a function of tracking a position of the domestic animal 9. As illustrated in FIG. 1, the processing unit 12 includes a tracking calculation unit 123. The tracking calculation unit 123 is configured to track a position of the domestic animal 9 based on positional information representing the position of the domestic animal 9. The tracking calculation unit 123 acquires the positional information from the detection device 33.
[0059] As illustrated in FIG. 1, the processing unit 12 further includes an abnormality detector 124. The abnormality detector 124 is configured to detect the domestic animal 9 present in a
12

certain space under an abnormal environment, of the space 7. More specifically, the abnormality detector 124 is configured to detect the domestic animal 9 present in the space under the abnormal environment based on a detection result of the detection device 33. [0060] (4.3) Equipment Controller
The equipment controller 13 illustrated in FIG. 1 is configured to control the environmental equipment 5 (the plurality of opening/closing windows 51 and the plurality of ventilation fans 52). More specifically, the equipment controller 13 is configured to control the environmental equipment 5 such that the actual apparent temperature of the domestic animal 9 agrees with a temperature suitable for the domestic animal 9 based on the apparent temperature distribution calculated by the second calculation unit 122 of the processing unit 12. In the first embodiment, the equipment controller 13 outputs the control contents (e.g., control parameters) for the environmental equipment 5 to the control device 4. The environmental equipment 5 controls the environment of the space 7 based on the apparent temperature distribution calculated by the second calculation unit 122 such that the actual apparent temperature of the domestic animal 9 agrees with the temperature suitable for the domestic animal 9.
[0061] When the apparent temperature distribution is calculated based on the biological detection information by the second calculation unit 122, the equipment controller 13 is configured to control the environmental equipment 5 so as to control an environment of a certain region where the domestic animal 9 is actually present, based on the biological detection information. Accordingly, the present apparent temperature calculation system can control the environment of the certain region where the domestic animal 9 is actually present in preference to a region where no domestic animal is present in the space 7. Consequently, the present apparent temperature calculation system can efficiently control the environment. [0062] The equipment controller 13 is configured to control the environmental equipment 5 so as to control an environment of the position of the domestic animal 9 tacked by the tracking calculation unit 123. Therefore, the present apparent temperature calculation system can accurately control the environment of the certain region where the domestic animal 9 is actually present. [0063] (4.4) Reporting Controller
The reporting controller 15 illustrated in FIG. 1 is configured to control the reporting device 21 so as to allow the reporting device 21 to report the domestic animal 9 present in the space under the abnormal environment and a position of the domestic animal 9 present in the space under the abnormal environment, when the abnormality detector 124 detects the domestic animal 9 present in the space under the abnormal environment. Therefore, the present apparent
13

temperature calculation system can allow a person to take, in an early stage, measures for the domestic animal 9 present in the space under the abnormal environment. [0064] (4.5) Storage Unit
The storage unit 14 illustrated in FIG. 1 stores therein the arithmetic model to be used by the processing unit 12. More specifically, the storage unit 14 stores therein a plurality of parameters to be used for the arithmetic model.
[0065] The storage unit 14 further stores therein the environmental distribution of the space 7, calculated by the first calculation unit 121. Also, the storage unit 14 stores therein history data of the environmental distribution (i.e., the calculation result of the first calculation unit 121) of the space 7. The history data of the environmental distribution of the space 7 includes, for example, a combination of the environmental distribution of the space 7 and a time point when the physical quantity relating to the environmental information (used for calculating the environmental distribution) is measured.
[0066] Furthermore, the storage unit 14 stores therein the apparent temperature distribution of the domestic animal 9, calculated by the second calculation unit 122. Also, the storage unit 14 stores therein history data of the apparent temperature distribution (i.e., the calculation result of the second calculation unit 122) of the domestic animal 9. The history data of the apparent temperature distribution of the domestic animal 9 includes, for example, a combination of the environmental distribution of the space 7 and the apparent temperature distribution of the domestic animal 9 at a time point when the environmental distribution is obtained. [0067] (4.6) Arithmetic Model
The arithmetic model (to be used by the processing unit 12 illustrated in FIG. 1) is a learned mode (i.e., a trained model), which is learned by using a plurality of pieces of data. The arithmetic model is, for example, a model for allowing one or more processors to function so as to output the apparent temperature distribution of the domestic animal 9 from an output layer 82 (see FIG. 4) of a Neural Network 8 (see FIG. 4), when the environmental distribution of the space 7 (see FIG. 2) is input to an input layer 81 (see FIG. 4) of the Neural Network 8. [0068] The arithmetic model is learned by using a plurality of pieces of history data. Each of the plurality of pieces of history data includes the combination of the environmental distribution of the space 7 and the apparent temperature distribution of the domestic animal 9 at the time point when the environmental distribution is obtained.
[0069] In the case of the Neural Network 8 illustrated in FIG. 4, the arithmetic model is learned by using the plurality of pieces of history data, as supervised data. Each parameter is adjusted such that the apparent temperature distribution is output from the output layer 82 of the Neural
14

Network 8 when the environmental distribution is input to the input layer 81 of the Neural
Network 8.
[0070] Using the arithmetic model (learned mode) as above can make the actual apparent
temperature of the domestic animal 9 closer to the temperature suitable for the domestic animal 9
over the whole of the space 7.
[0071] (5) Operation of Environment Control System
Hereinafter, the operation about how the environment control system 2 according to the first embodiment operates (i.e., the apparent temperature calculation method) will be described with reference to FIG. 4.
[0072] In a first step, the plurality of measuring devices 3 each measure the environmental information of the space 7 (in a step S1 of FIG. 4). More specifically, the measuring device 31 measures a prescribed physical quantity relating to the environment at the representative point 71 of the space 7, and the measuring device 32 measures a prescribed physical quantity relating to the environment at the representative point 72 of the space 7.
[0073] In a second step, the processing unit 12 of the apparent temperature calculation system 1 calculates the environmental distribution of the space 7, using sensor values (i.e., the environmental information at the representative points 71 and 72) obtained at the sensors of the measuring devices 31 and 32 (in a step S2 of FIG. 4). The processing unit 12 calculates, as the environmental distribution of the space 7, a temperature distribution of the space 7, a humidity distribution of the space 7 and a wind velocity distribution of the space 7, for example. The second step corresponds to a first calculation step.
[0074] In a third step, the apparent temperature distribution of the domestic animal 9 in the space 7 is calculated, using the environmental distribution calculated in the second step and the arithmetic model. The third step corresponds to a second calculation step. [0075] More specifically, in the third step, the processing unit 12 inputs the environmental distribution of the space 7 to the input layer 81 of the Neural Network 8 and outputs the apparent temperature distribution of the domestic animal 9 in the space 7 from the output layer 82 of the Neural Network 8 (in a step S3 of FIG. 4).
[0076] In a fourth step, the equipment controller 13 outputs, to the control device 4, the control contents based on the apparent temperature distribution calculated by the processing unit 12, thereby controlling the environmental equipment 5 (the plurality of opening/closing windows 51 and the plurality of ventilation fans 52) (in a step S4 of FIG. 4).
[0077] In a five step, the environmental equipment 5 operates according to the control by the control device 4 (in a step S5 of FIG. 4).
15

[0078] A (computer) program for causing one or more processors to execute the apparent temperature calculation method including the second, third and fourth steps is stored in the storage unit 14 of the apparent temperature calculation system 1. [0079] (6) Effect
The apparent temperature calculation system 1 according to the first embodiment calculates the apparent temperature distribution of the domestic animal 9 in the space 7 based on the environmental distribution of the space 7. The apparent temperature calculation system 1 can make the actual apparent temperature of the domestic animal 9 closer to the temperature suitable for the domestic animal 9 over the whole of the space 7, by controlling the environment of the space 7 in consideration of the apparent temperature distribution calculated by the first calculation unit 121.
[0080] In the apparent temperature calculation system 1 according to the first embodiment, the environmental information includes information about at least one selected from the temperature, the humidity and the wind velocity. Therefore, the apparent temperature calculation system 1, when calculating the apparent temperature distribution of the domestic animal 9, can improve the accuracy in the apparent temperature distribution of the domestic animal 9 by using the physical quantity affecting the apparent temperature of the domestic animal 9 with high probability. [0081] In the apparent temperature calculation system 1 according to the first embodiment, the environmental information represents the environment of at least one representative point (e.g., 71 and 72) in the space 7. Therefore, the apparent temperature calculation system 1 can contribute to reducing measurement points for the environmental information. Consequently, the apparent temperature calculation system 1 can reduce the number of the measuring devices 3 measuring the environmental information.
[0082] In the apparent temperature calculation system 1 according to the first embodiment, the plurality of the representative points 71 and 72 include the position located on the upwind side in the space 7 and the position located on the downwind side in the space 7. Therefore, the apparent temperature calculation system 1 can improve the accuracy in the environmental distribution of the space 7. Consequently, the apparent temperature calculation system 1 can calculate the apparent temperature distribution of the domestic animal 9 with high accuracy. [0083] The apparent temperature calculation system 1 according to the first embodiment calculates the apparent temperature distribution of the domestic animal 9, based on the biological detection information representing the presence of the domestic animal 9 and the environmental distribution of the space 7. Therefore, the apparent temperature calculation system 1 can calculate the apparent temperature distribution of the domestic animal 9 in the certain region
16

where the domestic animal 9 are actually present in preference to the region where no domestic animal is present in the space 7.
[0084] The apparent temperature calculation system 1 according to the first embodiment control the environmental equipment 5 so as to control the environment of the certain region where the domestic animal 9 is actually present based on the biological detection information. Therefore, the apparent temperature calculation system 1 can control the environment of the certain region where the domestic animal is actually present in preference to the region where no domestic animal is present in the space 7. Consequently, the apparent temperature calculation system 1 can efficiently control the environment.
[0085] The apparent temperature calculation system 1 according to the first embodiment detects and tracks the position of the domestic animal 9 in the space 7. Therefore, the apparent temperature calculation system 1 can accurately control the environment of the certain region where the domestic animal 9 is actually present.
[0086] In the apparent temperature calculation system 1 according to the first embodiment, the second calculation unit 122 is configured to calculate, as the three-dimensional distribution, the apparent temperature distribution of the domestic animal 9. Therefore, the sizes of the domestic animals 9 at each stage of growth can be considered. Consequently, the apparent temperature calculation system 1 can improve the accuracy in the apparent temperature distribution of the domestic animal 9.
[0087] The apparent temperature calculation system 1 according to the first embodiment detects the domestic animal 9 present in the space under the abnormal environment, and controls the reporting device 21 so as to allow the reporting device 21 to report at least one of the domestic animal 9 present in the space under the abnormal environment and a position of the domestic animal 9 present in the space under the abnormal environment. Therefore, the apparent temperature calculation system 1 can allow a person to take, in an early stage, measures for the domestic animal 9 present in the space under the abnormal environment. [0088] In the apparent temperature calculation system 1 according to the first embodiment, at least one of the first calculation unit 121 and the second calculation unit 122 is configured to execute the calculation, using the classifier to which machine learning is performed. Therefore, the apparent temperature calculation system 1 can calculate the apparent temperature distribution along the history so far in a short time. [0089] (7) Variations
Hereinafter, variations of the first embodiment will be described. [0090] As a variation of the first embodiment, the number of representative points of the
17

environment included in the environmental information is not limited to two or more, but may be one. In short, at least one representative point may be included in the environmental information. The environmental information includes information representing the environment of at least one representative point in the space 7.
[0091] As another variation of the first embodiment, the environmental equipment 5 may include an air conditioner. The air conditioner is installed at the building 6, and adjusts the temperature in the space 7 of the building 6 by discharging warm air or cold air into the space 7. [0092] As yet another variation of the first embodiment, the space 7 is not limited to the inside space of the building 6, but may be an opened type of space.
[0093] As yet another variation of the first embodiment, the reporting controller 15 is not limited to control the reporting device 21 so as to report both the domestic animal 9 present in the space under the abnormal environment and the position of the domestic animal 9 present in the space under the abnormal environment, when the domestic animal 9 present in the space under the abnormal environment are detected. The reporting controller 15 may control the reporting device 21 so as to report only the domestic animal 9 present in the space under the abnormal environment, or only the position of the domestic animal 9 present in the space under the abnormal environment. In short, the reporting controller 15 preferably controls the reporting device 21 so as to allow the reporting device 21 to report at least one of the domestic animal 9 present in the space under the abnormal environment and the position of the domestic animal 9 present in the space under the abnormal environment, when the abnormality detector 124 detects the domestic animal 9 present in the space under the abnormal environment. [0094] The reporting device 21 reports the information according to the instruction from the reporting controller 15. Therefore, the reporting device 21 is not limited to report both the domestic animal 9 present in the space under the abnormal environment and the position of the domestic animal 9 present in the space under the abnormal environment. The reporting device 21 may report only the domestic animal 9 present in the space under the abnormal environment, or only the position of the domestic animal 9 present in the space under the abnormal environment. In short, the reporting device 21 preferably reports at least one of the domestic animal 9 present in the space under the abnormal environment and the position of the domestic animal 9 present in the space under the abnormal environment.
[0095] Note that, the arithmetic model (learned mode) to be used by the processing unit 12 in the first embodiment is generated by machine learning, as described above. The processing unit 12 may be implemented as any type of artificial intelligence or system. Here, the machine learning algorithm is a neural network, as one example. However, the machine learning
18

algorithm is not limited to the neural network. Examples of the machine learning algorithm may include eXtreme Gradient Boosting (XGB) regression, Random Forest, decision tree, Logistic Regression, Support vector machine (SVM), Naive Bayes classifier and k-nearest neighbors. Examples of the machine learning algorithm may further include Gaussian Mixture Model (GMM) and k-means clustering.
[0096] The type of learning method in the first embodiment is supervised learning, as one example. However, the type of learning method is not limited to be the supervised learning, but may be unsupervised learning, or reinforcement learning.
[0097] The apparent temperature calculation system according to each of the variations described above also has the same effect as the apparent temperature calculation system 1 according to the first embodiment.
[0098] The apparent temperature calculation system 1 or an execution object of the apparent temperature calculation method according to the present disclosure includes a computer system. The computer system may include a processor and a memory as principal hardware components. The functions of the apparent temperature calculation system 1 or the execution object of the apparent temperature calculation method according to the present disclosure may be performed by making the processor execute a program stored in the memory of the computer system. The program may be stored in advance in the memory of the computer system. Alternatively, the program may also be downloaded through a telecommunications line or be distributed after having been recorded in some non-transitory storage medium such as a memory card, an optical disc, or a hard disk drive, any of which is readable for the computer system. The processor of the computer system may be implemented as a single or a plurality of electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). Those electronic circuits may be either integrated together on a single chip or distributed on multiple chips, whichever is appropriate. Those multiple chips may be integrated together in a single device or distributed in multiple devices without limitation.
[0099] The apparent temperature calculation system 1 in the first embodiment includes the acquiring unit 11, the processing unit 12, the equipment controller 13, the storage unit 14 and the reporting controller 15. However, the components of the acquiring unit 11, the equipment controller 13, the storage unit 14 and the reporting controller 15 are not essential for the apparent temperature calculation system 1. That is to say, the apparent temperature calculation system 1 may not include at least one of the acquiring unit 11, the equipment controller 13, the storage unit 14 and the reporting controller 15, as long as including the processing unit 12. [0100] The apparent temperature calculation system 1 may be implemented as a single device
19

where the components are housed in a single housing, or as multiple devices. At least one element of the acquiring unit 11, the processing unit 12, the equipment controller 13, the storage unit 14 and the reporting controller 15 may be provided separately from the remaining elements such that they are distributed in multiple devices. For example, the processing unit 12 may be provided separately from the equipment controller 13 such that they are distributed in multiple devices. Alternatively, the functions of each of the acquiring unit 11, the processing unit 12, the equipment controller 13, the storage unit 14 and the reporting controller 15 may be distributed in multiple devices. For example, at least one element of the first calculation unit 121, the second calculation unit 122, the tracking calculation unit 123 and the abnormality detector 124 may be provided separately from the remaining elements such that they are distributed in multiple devices. Still alternatively, at least some functions of the apparent temperature calculation system 1 may be implemented as a cloud computing system as well. [0101] (Second Embodiment)
Hereinafter, a control system according to a second embodiment will be described with reference to drawings. FIGS. 5, 6, 7A, 7B, 9 and 10 to be referred to in the following embodiment and so on are schematic drawings. The ratio of the dimensions including thicknesses, of respective constituent elements illustrated on the drawings does not always reflect their actual dimensional ratio. [0102] (1) Control System
A configuration of a control system 100 according to the second embodiment will be described with reference to the drawings.
[0103] As illustrated in FIGS. 5 and 6, the control system 100 according to the second embodiment includes a plurality of baffle members 2A (three baffle members in the example of the drawings), an environmental equipment (ventilation equipment) 5 and a control device 4. The control system 100 according to the second embodiment controls a wind velocity of air in an inside space (space 7).
[0104] The control system 100 is a system to control a wind velocity of air in an inside space (space 7) of a building 6. The control system 100 is applied to a livestock barn where domestic animals 9 are reared, or the like. The livestock barn is a chicken house where chickens are reared, for example. However, the livestock barn is not limited to the chicken house. The livestock barn may be a pigpen where pigs as the domestic animals 9 are reared. Alternatively, the livestock barn may be a cow barn where cows as the domestic animals 9 are reared. [0105] (2) Building
The building 6 for which the control system 100 is provided will be described with
20

reference to the drawings.
[0106] As illustrated in FIGS. 5 and 6, the building 6 includes a building body 61 with an
approximately rectangular parallelepiped shape, for example. Also, the building 6 has the
inside space (space 7). The building 6 further includes the control system 100.
[0107] In the example of FIG. 5, the building 6 is a livestock barn. When the building 6 is the
livestock barn, the building body 61 corresponds to a main body of the livestock barn. Many
domestic animals 9 are reared in the inside space (space 7) of the building 6.
[0108] The building body 61 includes two first sidewalls 62 and 63, and two second sidewalls
64 and 65. To the building body 61, the plurality of baffle members 2A and the environmental
equipment (ventilation equipment) 5 are attached.
[0109] The two first sidewalls 62 and 63 have, for example, rectangular shapes and are
disposed along a longitudinal direction D1 of the building 6. The two first sidewalls 62 and 63
are arranged to face each other via the inside space (space 7) in a short-length direction D2 of the
building 6.
[0110] The two second sidewalls 64 and 65 have, for example, rectangular shapes and are
disposed along the short-length direction D2 of the building 6. The two second sidewalls 64
and 65 are arranged to face each other via the inside space (space 7) in the longitudinal direction
D1 of the building 6.
[0111] The inside space (space 7) is surrounded by the building body 61. More specifically,
the inside space (space 7) is surrounded by the two first sidewalls 62 and 63 and the two second
sidewalls 64 and 65.
[0112] The building 6 further includes a plurality of air supply ports 66 (two air supply ports in
the example of the drawings) and an air exhaust port 67. The air is sucked from the outside of
the building 6 to the inside space (space 7) through each of the plurality of air supply ports 66.
Also, the air is exhausted from the inside space (space 7) to the outside of the building 6 through
the air exhaust port 67.
[0113] The plurality of air supply ports 66 (air supply ports 661 and 662) are disposed at lower
ends of the first sidewalls 62 and 63 along the longitudinal direction D1 of the building 6.
More specifically, one air supply port 661 is disposed at a lower end of the first sidewall 62 on a
first end side (the side close to the second sidewall 64) of the building 6 in the longitudinal
direction D1. The other air supply port 662 is disposed at a lower end of the first sidewall 63
on the first end side of the building 6 in the longitudinal direction D1. The air supply ports 661
and 662 are arranged to face each other in the short-length direction D2 of the building 6.
[0114] The air exhaust port 67 is disposed on a second end side (the side close to the second
21

sidewall 65) of the building 6 in the longitudinal direction D1. More specifically, the air
exhaust port 67 is arranged near a center of the second sidewall 65. Alternatively, the air
exhaust port 67 may be arranged near an upper end of the second sidewall 65.
[0115] The number of air supply ports 66 is not limited to two, but may be one, three or more.
In short, the number of air supply ports 66 may be one or more. The number of air exhaust
ports 67 is not limited to one, but may be two or more. In short, the number of air exhaust ports
67 may be one or more.
[0116] (3) Each Component of Control System
Hereinafter, each of components of the control system 100 according to the second embodiment will be described with reference to the drawings. [0117] (3.1) Baffle Member
As illustrated in FIGS. 5 and 6, the plurality of baffle members 2A are disposed between the air supply ports 66 and the air exhaust port 67 in the inside space (space 7) of the building 6. In the example of FIG. 5, the number of baffle members 2A is three. Each baffle member 2A is suspended from a ceiling 69 of the building 6 such that a space 73 exists between a lower end 20A of the corresponding baffle member 2A and a floor surface 68 of the building 6. In other words, each baffle member 2A is suspended from the ceiling 69 without touching the floor surface 68 of the building 6. Each baffle member 2A is made of, for example, a member of allowing light to transmit therethrough, or a transparent member.
[0118] Each of the plurality of baffle members 2A is disposed to block a part of the inside space (space 7) in the longitudinal direction D1. That is to say, the plurality of baffle members 2A block the air flowing along the longitudinal direction D1.
[0119] In the inside space (space 7), the wind velocity of air flowing around a position where each baffle member 2A is arranged is higher than the wind velocity of air flowing through a position where no baffle member 2A is arranged. The greater the size of the space 73 between the floor surface 68 of the building 6 and the lower end 20A of each baffle member 2A is, the lower the wind velocity of air flowing through the space 73 is.
[0120] Each baffle member 2A in the second embodiment is a board disposed in the inside space (space 7) of the building 6 such that a normal direction of the board is along a direction (longitudinal direction D1) orthogonal to the height direction D3 of the building 6. Therefore, the baffle member 2A is hardly deformed, even when air blows against the baffle member 2A. Consequently, the present control system stably can control the wind velocity of air. [0121] The plurality of baffle members 2A include a first baffle member 21A, a second baffle member 22A and a third baffle member 23A. The first baffle member 21A, the second baffle
22

member 22A and the third baffle member 23A are arranged at intervals in that order from the second sidewall 64 in the longitudinal direction D1 of the building 6. The first baffle member 21A is disposed closest to the air supply ports 66 among the plurality of baffle members 2A in the longitudinal direction D1. On the other hand, the third baffle member 23A is disposed closest to the air exhaust port 67 among the plurality of baffle members 2A in the longitudinal direction D1.
[0122] The baffle member 2A is located such that the wind velocity is even in a region between the baffle member 2A and the air exhaust port 67, of the inside space (space 7) of the building 6. In other words, the baffle member 2A is located to reduce unevenness of the wind velocity at a plurality of positions in the region between the baffle member 2A and the air exhaust port 67, of the inside space (space 7) of the building 6. Therefore, the present control system can smoothly discharge heat in the inside space (space 7) of the building 6 to the outside of the building 6. [0123] The “wind velocity is even” mentioned herein means that the unevenness of the wind velocity is equal to or less than 1.0 m/sec. More preferably, the unevenness of the wind velocity is equal to or less than 0.5 m/sec. Also, the unevenness of the wind velocity is preferably equal to or less than 20% of the average wind velocity.
[0124] As described above, the number of baffle members 2A is three or more. The three or more baffle members 2A are arranged such that intervals are even. Each of the intervals is an interval between corresponding two adjacent baffle members 2A of the three or more baffle members 2A. In other words, an interval L1 between the first baffle member 21A and the second baffle member 22A is the same as an interval L2 between the second baffle member 22A and the third baffle member 23A.
[0125] Note that, the three or more baffle members 2A may be arranged such that intervals are uneven. Each of the intervals is an interval between corresponding two adjacent baffle members 2A of the three or more baffle members 2A. In other words, the interval L1 between the first baffle member 21A and the second baffle member 22A may be different from the interval L2 between the second baffle member 22A and the third baffle member 23A. Accordingly, the present control system can perform the wind velocity control in accordance with the states of the building 6 and the inside space (space 7) of the building 6. [0126] Also, the number of baffle members 2A is two or more. Heights of two or more baffle members 2A are even. In other words, a height T1 of the first baffle member 21A is the same as each of a height T2 of the second baffle member 22A and a height T3 of the third baffle member 23A. The “height of the baffle member” mentioned herein means a height (distance) from the floor surface 68 of the building 6 to a lower end of the baffle member 2A. More
23

specifically, the height T1 of the first baffle member 21A corresponds to a height (distance) from the floor surface 68 of the building 6 to a lower end 210A of the first baffle member 21A. The height T2 of the second baffle member 22A corresponds to a height (distance) from the floor surface 68 of the building 6 to a lower end 220A of the second baffle member 22A. The height T3 of the third baffle member 23A corresponds to a height (distance) from the floor surface 68 of the building 6 to a lower end 230A of the third baffle member 23A.
[0127] The heights of two or more baffle members 2A may be uneven. In other words, the height T1 of the first baffle member 21A, the height T2 of the second baffle member 22A and the height T3 of the third baffle member 23A may be different from one another. Alternatively, any one of the height T1 of the first baffle member 21A, the height T2 of the second baffle member 22A and the height T3 of the third baffle member 23A may be different from the remaining two heights. Accordingly, the present control system can perform the wind velocity control in accordance with the states of the building 6 and the inside space (space 7) of the building 6. In particular, when ventilation fans 52 are disposed at the air exhaust port 67, air flowing through a region near the exhaust port 67 has the kinetic energy higher than that of air flowing through a region near the air supply ports 66. Therefore, even when a space 733 (see FIG. 7) between the third baffle member 23A and the floor surface 68 is large in size, air flowing through the space 733 has the wind velocity higher than that of each of: air flowing through a space 731 (see FIG. 7) between the first baffle member 21A and the floor surface 68; and air flowing through a space 732 (see FIG. 7) between the second baffle member 22A and the floor surface 68. [0128] The number of baffle members 2A is not limited to three. The number of baffle members 2A may be one, two, four or more. In short, the control system 100 may include at least one baffle member 2A. [0129] (3.2) Environmental Equipment (Ventilation Equipment)
As illustrated in FIGS. 5 and 6, the environmental equipment (ventilation equipment) 5 includes a plurality of opening/closing windows 51 (two opening/closing windows in the example of the drawings) and a plurality of ventilation fans 52 (five ventilation fans in the example of the drawings). [0130] (3.2.1) Opening/closing Window
As illustrated in FIGS. 5 and 6, the plurality of opening/closing windows 51 are disposed at the air supply ports 66 of the building 6. More specifically, one opening/closing window 511 of the plurality of opening/closing windows 51 (511, 512) is disposed at the air supply port 661 in the first sidewall 62 disposed along the longitudinal direction D1, and the other opening/closing window 512 is provided at the air supply port 662 in the first sidewall 63
24

disposed along the longitudinal direction D1.
[0131] The plurality of opening/closing windows 51 are referred to as so-call tunnel doors, and
configured to turn vertically to be opened or closed. When any opening/closing window 51 is
opened, air can be made enter the inside space (space 7) from the outside of the building 6
through the corresponding air supply port 66.
[0132] (3.2.2) Ventilation Fan
As illustrated in FIGS. 5 and 6, the plurality of ventilation fans 52 are disposed at the air exhaust port 67. More specifically, the plurality of ventilation fans 52 are disposed on the opposite side to the plurality of opening/closing windows 51 in the longitudinal direction D1. That is to say, the plurality of ventilation fans 52 are disposed on the second sidewall 65. [0133] The plurality of ventilation fans 52 are arranged side by side in a row in the short-length direction D2. More specifically, ventilation fans 521, 522, 523, 524 and 525 are arranged in that order from the first sidewall 63 in the short-length direction D2.
[0134] The plurality of ventilation fans 52 exhaust air in the inside space (space 7) of the building 6 to the outside of the building 6. More specifically, the plurality of ventilation fans 52 are disposed so as to exhaust the air in the inside space (space 7) in the almost same direction. Accordingly, the air in the inside space (space 7) can be sucked at a position on an air exhaust side and exhausted to the outside of the building 6. [0135] (3.3) Control Device
The control device 4 illustrated in FIG. 5 has a function of controlling the plurality of ventilation fans 52. More specifically, the control device 4 controls the plurality of ventilation fans 52 individually. Also, the control device 4 has a function of accepting an input relating to an outside air temperature out of the building 6.
[0136] The control device 4 controls the plurality of ventilation fans 52 in accordance with the outside air temperature input to the control device 4. More specifically, the control device 4 adjusts the number of ventilation fans 52 running, of the plurality of the ventilation fans 52, in accordance with the outside air temperature.
[0137] More specifically, the control device 4 increases the number of ventilation fans 52 running, of the plurality of the ventilation fans 52, as the outside air temperature input to the control device 4 raises. On the other hand, the control device 4 decreases the number of ventilation fans 52 running, of the plurality of the ventilation fans 52, as the outside air temperature input to the control device 4 falls. Accordingly, even when the outside air temperature out of the building 6 fluctuates, the present control system can keep the wind velocity of air in the inside space (space 7) of the building 6 within a desired velocity range.
25

[0138] Note that, the control device 4 may acquire the outside air temperature by manual inputting, or by automatically inputting from a temperature sensor located near the outside of the building 6. In the case that the control device 4 acquires the outside air temperature by manual inputting, a person can manually input a correction for the outside air temperature of the building 6. Therefore, the outside air temperature with high accuracy can be more easily acquired. On the other hand, in the case that the control device 4 acquires the outside air temperature by automatically inputting from the temperature sensor, the present control system can realize 24-hour automatically controlling of the wind velocity of air in the inside space (space 7). [0139] (4) Control Method
Hereinafter, a control method according to the second embodiment will be described with reference to FIGS. 7A and 7B. The control method according to the second embodiment is a method for controlling the wind velocity of air in the inside space (space 7) of the building 6. FIG. 7A shows a distribution relating to the wind velocity by the control method according to the second embodiment. FIG. 7B shows a distribution relating to the wind velocity by a comparative example. The height (distance) from the floor surface 68 (see FIG. 6) of the building 6 to the lower end 20A (see FIG. 6) of each baffle member 2A is 1.5 m. The wind velocity shown in FIGS 7A and 7B is data at a position where the height from the floor surface 68 is 300 mm.
[0140] As illustrated in FIG. 7B, the comparative example is an example that no baffle member 2A is disposed in an inside space (space 7A) of a building 6A. Since no baffle member 2A is disposed in the comparative example, the wind velocity of air in the inside space (space 7A) is low. For example, the wind velocity of air in a main region of the inside space (space 7A) is about 1.0 m/sec at a position where the height from the floor surface 68 is 300 mm. The “main region of the inside space (space 7A)” mentioned herein means a region other than a region where the air supply ports 66 (see FIG. 5) and the air exhaust port 67 (see FIG. 5) are arranged, of the inside space (space 7A). More specifically, the “main region of the inside space (space 7A)” corresponds to a region near a center in the short-length direction D2. That is to say, regions at both ends in the short-length direction D2 are not included in the main region of the inside space (space 7A). When the building 6A is a livestock barn, the main region of the inside space (space 7A) may be a region where many domestic animals 9 are present. [0141] On the other hand, the plurality of baffle members 2A are disposed in the control method according to the second embodiment, as illustrated in FIG. 6. Each of the plurality of baffle members 2A is suspended from the ceiling 69 of the building 6 such that the space 73 exists between the lower end 20A of the corresponding baffle member 2A and the floor surface
26

68 of the building 6 between the air supply ports 66 (see FIG. 5) and the air exhaust port 67 (see FIG. 5) in the inside space (space 7) of the building 6. The air supply ports 66 are openings through which air is supplied from the outside of the building 6 to the inside space (space 7), as described above. The air exhaust port 67 is an opening through which air is exhausted from the inside space (space 7) to the outside of the building 6, as described above. [0142] In this case, the space 73 formed by each baffle member 2A has a cross-sectional area smaller than that of the remaining space. Accordingly, as illustrated in FIG. 7A, the air flows through the space 73 at a high wind velocity. More specifically, the wind velocity of air can be increased in a space between a first baffle member 21A arranged closest to the air supply ports 66 and a third baffle member 23A arranged closest to the air exhaust port 67, of the inside space (space 7) of the building 6, in the example of FIG. 7A. For example, the wind velocity of air in a main region of the inside space (space 7) is about 2.5 m/sec at a position where the height from the floor surface 68 is 300 mm. Accordingly, the present control method can further increase the wind velocity of air in the inside space (space 7), compared with the case where no baffle member 2A is disposed. Consequently, the present control method can easily discharge heat staying in the inside space (space 7) to the outside. The “main region of the inside space (space 7)” mentioned herein corresponds to a region between the first baffle member 21A (arranged closest to the air supply ports 66) and the third baffle member 23A (arranged closest to the air exhaust port 67), of the inside space (space 7). More specifically, the “main region of the inside space (space 7)” corresponds to a region near a center in the short-length direction D2. That is to say, regions at both ends in the short-length direction D2 are not included in the main region of the inside space (space 7). When the building 6 is a livestock barn, the main region of the inside space (space 7) may be a region where many domestic animals 9 are present. [0143] In the second embodiment, when air sucked from the opening/closing windows 51 is sucked out by the ventilation fans 52 to be exhausted to the outside, a spiral air flow generates in the inside space (space 7). The spiral air flow hits the lower end 20A of the baffle member 2A in the process the spiral air moves from the opening/closing windows 51 to the ventilation fans 52, thereby the wind velocity of the spiral air flow being increased. Furthermore, the wind velocity is reduced before the spiral air flow reaches the next baffle member 2A, but when the spiral air flow hits the next baffle member 2A, the wind velocity is again increased. Therefore, the spiral air flow can be controlled such that the wind velocity is kept almost constant even at any position in the inside space (space 7) of the building 6 elongated.
[0144] For example, when the building 6 is a chicken house, the poultry farmer training guidance manual of the industry publishes an index that the wind velocity suitable for chickens is
27

almost 3.0 m/sec to 4.0 m/sec. Accordingly, it is preferred that the wind velocity in the inside space (space 7) can be kept in a range of the above numerical values (3.0 m/sec to 4.0 m/sec). In the example of FIG. 7A, the wind velocity of air is increased from 1.0 m/sec to 2.5 m/sec at a position where the height from the floor surface 68 is 300 mm. The height of 300 mm from the floor surface 68 is approximate to the height of the head of the chicken. Therefore, the effect of cooling the chickens can be enhanced.
[0145] In this case, the plurality of baffle members 2A can make the wind velocity of air uniform in the space between the first baffle member 21A and the third baffle member 23A, of the inside space (space 7). In the example of FIG. 7B, the wind velocity is in a range of almost 1.0 m/sec to 2.0 m/sec at the position where the height from the floor surface 68 is 300 mm. On the other hand, in the example of FIG. 7A, the wind velocity is in a range of almost 2.5 m/sec to 3.0 m/sec at the position where the height from the floor surface 68 is 300 mm. Accordingly, it is understood that the wind velocity in the example of FIG. 7A is smaller in unevenness than that in the example FIG. 7B. [0146] (5) Effect
In the control system 100 according to the second embodiment, the baffle member 2A is disposed in the inside space (space 7) of the building 6, and suspended from the ceiling 69 of the building 6 such that the space 73 exists between the lower end 20A thereof and the floor surface 68 of the building 6. Accordingly, the control system 100 can narrow the space 73 between the lower end 20A of the baffle member 2A and the floor surface 68, and therefore the wind velocity of air is increased when the air flows through the space 73. Consequently, the control system 100 can easily discharge heat staying in the inside space (space 7) of the building 6 to the outside of the building 6.
[0147] When the control system 100 is applied to the livestock barn where the domestic animals 9 are reared, it can reduce a stress which the domestic animal 9 receives by heat staying in the inside space (space 7). In particular, the chickens have the whole bodies covered with feathers, and have no sweat glands. For this reason, when the domestic animals 9 are the chickens, it is important to discharge the heat staying in the inside space (space 7) to avoid getting the inside space (space 7) hot.
[0148] In the control system 100 according to the second embodiment, the baffle member 2A is located to reduce unevenness of the wind velocity at a plurality of positions in a region between the baffle member 2A and the air exhaust port 67. Therefore, the control system 100 can smoothly discharge heat in the inside space (space 7) of the building 6 to the outside of the building 6.
28

[0149] In the control system 100 according to the second embodiment, the opening/closing windows 51 are disposed at the air supply ports 66, which are disposed at the lower ends of the first sidewalls 62 and 63 along the longitudinal direction D1 of the building 6. Therefore, the control system 100 can adjust the amount of air to be supplied from the air supply ports 66 to the inside space (space 7) in accordance with opening states (opening/closing degrees) of the opening/closing windows 51.
[0150] In the control system 100 according to the second embodiment, the intervals may be uneven. Each of the intervals is an interval between corresponding two adjacent baffle members 2A. Therefore, the control system 100 can perform the wind velocity control in accordance with the states of the building 6 and the inside space (space 7) of the building 6. [0151] In the control system 100 according to the second embodiment, the heights of the two or more baffle members 2A may be uneven. Therefore, the control system 100 can perform the wind velocity control in accordance with the states of the building 6 and the inside space (space 7) of the building 6.
[0152] In the control system 100 according to the second embodiment, the ventilation fan 52 is disposed at the air exhaust port 67 and exhausts air in the inside space (space 7) to an outside of the building 6. Therefore, the air in the inside space (space 7) can be sucked on the air exhaust side and exhausted to the outside of the building 6.
[0153] The control system 100 according to the second embodiment increases the number of ventilation fans 52 running, as the outside air temperature out of the building 6 raises, and decreases the number of ventilation fans 52 running, as the outside air temperature falls. Therefore, even when the outside air temperature out of the building 6 fluctuates, the control system 100 can keep the wind velocity of air in the inside space (space 7) of the building 6 within a desired velocity range.
[0154] In the control system 100 according to the second embodiment, the building 6 is the livestock barn. Accordingly, the control system 100 can reduce heat staying even in the inside space (space 7) of the livestock barn, and reduce the stress of the domestic animal 9 due to the heat staying. Consequently, the control system 100 can provide a growth environment comfortable for the domestic animal 9.
[0155] Note that, there is known a system of radiating light of 550 nm to 650 nm, which is capable of further preventing an increase in a temperature in a chicken coop (in an inside space of a building) or a poultry (a building), compared with infrared light. However, the known system has no function of discharging heat in the chicken coop. That is to say, the known system has no function of controlling an air flow in the chicken coop.
29

[0156] The control system 100 according to the second embodiment can easily increase the wind velocity of air in the inside space (space 7) of the building 6. [0157] (6) Variations
Hereinafter, variations of the second embodiment will be described. [0158] As a first variation of the second embodiment, a control system 100a may further include a plurality of suspending mechanisms 9A (three suspending mechanisms in the example of FIG. 8), as illustrated in FIG. 8. The plurality of suspending mechanisms 9A are capable of moving the plurality of baffle members 2A in the height direction D3 (see FIG. 6) of the building 6 (see FIG. 6).
[0159] In the case of the first variation, each baffle member 2A is a flexible member such as a vinyl sheet. Examples of each baffle member 2A may include a roll curtain and a mechanism as a drop curtain.
[0160] The plurality of suspending mechanisms 9A are disposed to correspond to the plurality of baffle members 2A in one-to-one. More specifically, the plurality of suspending mechanisms 9A include a first suspending mechanism 91A, a second suspending mechanism 92A and a third suspending mechanism 93A. The first suspending mechanism 91A is disposed to correspond to the first baffle member 21A. The second suspending mechanism 92A is disposed to correspond to the second baffle member 22A. The third suspending mechanism 93A is disposed to correspond to the third baffle member 23A. Each suspending mechanism 9A has a function of moving a corresponding baffle member 2A in the height direction D3 of the building 6. When the plurality of baffle members 2A are roll curtains, each suspending mechanism 9A can displace the lower end 20A (see FIG. 6) of the corresponding baffle member 2A in the height direction D3 by rolling the corresponding baffle member 2A up. When the plurality of baffle members 2A are mechanisms as drop curtains, each suspending mechanism 9A can displace the lower end 20A of the corresponding baffle member 2A in the height direction D3 by vertically moving the lower end 20A of the corresponding baffle member 2A.
[0161] Also in the first variation, the control system 100a includes a control device 4a as illustrated in FIG. 8, instead of the control device 4.
[0162] The control device 4a has a function of controlling the plurality of suspending mechanisms 9A together with a function of controlling a plurality of ventilation fans 52 (five ventilation fans in the example of FIG. 8). More specifically, the control device 4a is configured to control the plurality of suspending mechanisms 9A individually. When changing the height of the lower end 20A (see FIG. 6) for each baffle member 2A, the control device 4a controls the plurality of suspending mechanisms 9A individually.
30

[0163] As described above, in the control system 100a according to the first variation, the plurality of suspending mechanisms 9A are disposed and capable of moving the baffle members 2A in the height direction D3 (see FIG. 6) of the building 6 (see FIG. 6). Accordingly, the control system 100a can easily change the height of each baffle member 2A. In other words, the control system 100a can easily change the height from the floor surface 68 (see FIG. 6) of the building 6 to the lower end 20A of each baffle member 2A. Consequently, the control system 100a can adjust the arrangement of each baffle member 2A in accordance with the season, the time of day, or the temperature of the inside space (space 7) (see FIG. 6) of the building 6. For example, when the domestic animal 9 is present in the inside space (space 7), the control system 100a can adjust the height of each baffle member 2A in accordance with the growth state of the domestic animal 9.
[0164] As a second variation of the second embodiment, a control system 100b may include an environmental equipment (ventilation equipment) 5b as illustrated in FIG. 9, instead of the environmental equipment (ventilation equipment) 5 (see FIG. 5).
[0165] The environmental equipment (ventilation equipment) 5b includes a plurality of ventilation fans 52b (six ventilation fans in the example of FIG. 9) disposed at two air supply ports 66, instead of the plurality of ventilation fans 52 (see FIG. 5) disposed at the air exhaust port 67. For example, the same number of ventilation fans 52b are disposed at the two air supply ports 66. More specifically, three ventilation fans 52b, 522b and 523b are arranged in that order at an air supply port 661 in the longitudinal direction D1. Also, three ventilation fans 524b, 525b and 526b are arranged in that order at an air supply port 662 in the longitudinal direction D1. The plurality of ventilation fans 52b supplies air in the outside of the building 6 to the inside space (space 7).
[0166] The environmental equipment (ventilation equipment) 5b further includes an opening/closing window 51b disposed at an air exhaust port 67, instead of the opening/closing windows 51 (see FIG. 5) disposed at the air supply ports 66.
[0167] A control device 4b of the control system 100b according to the second variation has a function of controlling the plurality of ventilation fans 52b. More specifically, the control device 4b controls the plurality of ventilation fans 52b individually. Note that, regarding functions of the control device 4b similar to those of the control device 4 of the second embodiment, explanations thereof will be omitted as appropriate.
[0168] In the control system 100b according to the second variation, the plurality of ventilation fans 52b are disposed at the air supply ports 66 to supply air in the outside of the building 6 to the inside space (space 7). Accordingly, the control system 100b can exhaust the air in the
31

inside space (space 7) so as to be pushed out from the air exhaust port 67 by sucking the air from
the air supply ports 66.
[0169] As a third variation of the second embodiment, a control system 100c may include an
environmental equipment (ventilation equipment) 5c as illustrated in FIG. 10. The
environmental equipment (ventilation equipment) 5c includes both a plurality of ventilation fans
52 disposed at an air exhaust port 67 and a plurality of ventilation fans 52b disposed at air supply
ports 66.
[0170] The control device 4c of the control system 100c according to the third variation has a
function of controlling the plurality of ventilation fans 52 and the plurality of ventilation fans
52b. More specifically, the control device 4c controls the plurality of ventilation fans 52 and
the plurality of ventilation fans 52b individually. Note that, regarding functions of the control
device 4c similar to those of the control device 4 of the second embodiment, explanations thereof
will be omitted as appropriate.
[0171] In the control system 100c according to the third variation, the ventilation fans 52 and
52b are disposed at both the air supply ports 66 and the air exhaust port 67 to supply air in the
outside of the building 6 to the inside space (space 7). Accordingly, the control system 100c
can exhaust the air in the inside space (space 7) so as to be pushed out from the air exhaust port
67 by sucking the air from the air supply ports 66, and further can exhaust the air in the inside
space (space 7) so as to be sucked by sucking the air on the side of the air exhaust port 67.
Consequently, the control system 100c can enhance capacities of the air supplying and the air
exhausting.
[0172] Note that, as another variation according to the second embodiment, the baffle member
2A may be capable of being removed from the building 6. Accordingly, a person can attach the
baffle member 2A to the building 6 or remove it from the building 6 in accordance with the
necessity of the baffle member 2A. For example, when the domestic animal 9 is present in the
inside space (space 7), the person can attach the baffle member 2A to the building 6 or remove it
from the building 6 in accordance with the growth state of the domestic animal 9.
[0173] As yet another variation according to the second embodiment, the baffle member 2A
may be flexible vinyl sheet.
[0174] The building 6 is not limited to the livestock barn, but may be a building where people
are present. The building 6 may be a school gymnasium, for example. Generally, there is a
tendency to avoid constantly blowing the wind on a human. For example, while people are
exercising in the gymnasium, at least one baffle member 2A may be preferably installed to
prevent people from getting heatstroke. In this case, the wind velocity of air is preferably
32

controlled to a desired velocity at any height (e.g., a height of a human head) in the inside space
(space 7) of the building 6.
[0175] As yet another variation according to the second embodiment, a moving mechanism
may be provided to move each of the plurality of baffle members 2A in the longitudinal direction
D1 of the building 6. Accordingly, a person can easily change the interval between the adjacent
baffle members 2A.
[0176] As yet another variation according to the second embodiment, the air supply port 66
may be disposed in the second sidewall 64 of the building 6 and the air exhaust ports 67 may be
disposed in the first sidewalls 62 and 63 of the building 6.
[0177] The control system according to each of the variations described above also has the
same effect as the control system 100 according to the second embodiment.
[0178] The exemplary embodiments and variations described above are only parts of various
embodiments and variations of the present disclosure. The exemplary embodiments and
variations may be readily modified in various manners depending on a design choice or any
other factor, as long as the purpose of the present disclosure can be attained.

calculation, using a classifier to which machine learning is performed.
[0199] The apparent temperature calculation system (1) according to the tenth aspect can
calculate the apparent temperature distribution along the history so far in a short time.
[0200] An environment control system (2) according to an eleventh aspect includes the
apparent temperature calculation system (1) of any one of the first to tenth aspects, a measuring
device (3), and an environmental equipment (5; 5b; 5c). The measuring device (3) is

[0201] The environment control system (2) according to the eleventh aspect can make, in the
apparent temperature calculation system (1), the actual apparent temperature of the domestic
animal (9) closer to the temperature suitable for the domestic animal (9) over the whole of the
space (7), by controlling the environment of the space (7) in consideration of the apparent

[0202] An apparent temperature calculation method according to a twelfth aspect includes a

[0203] The apparent temperature calculation method according to the twelfth aspect can make
the actual apparent temperature of the domestic animal (9) closer to the temperature suitable for
the domestic animal (9) over the whole of the space (7), by controlling the environment of the
space (7) in consideration of the apparent temperature distribution calculated in the first
calculation step.
[0204] A program according to a thirteenth aspect is designed to cause one or more processors
to execute the apparent temperature calculation method of the twelfth aspect.
[0205] The program according to the thirteenth aspect can make the actual apparent
36

temperature of the domestic animal (9) closer to the temperature suitable for the domestic animal (9) over the whole of the space (7), by controlling the environment of the space (7) in consideration of the apparent temperature distribution calculated in the first calculation step. [0206] An environment control system (2) according to a fourteenth aspect includes the apparent temperature calculation system (1) of any one of the first to tenth aspects and a control system (100; 100a; 100b; 100c). The control system (100; 100a; 100b; 100c) is applied together with a ventilation equipment (5; 5b; 5c) of ventilating an inside space (space 7) of a building (6). The control system (100; 100a; 100b; 100c) is configured to control a wind velocity of an air flow, which is supplied from an air supply port (66) of the building (6) and exhausted from an air exhaust port (67) of the building (6) to an outside of the building (6) via the inside space (space 7). The control system (100; 100a; 100b; 100c) includes at least one baffle member (2A). The at least one baffle member (2A) is disposed between the air supply port (66) and the air exhaust port (67) in the inside space (space 7). The at least one baffle member (2A) is suspended from a ceiling (69) of the building (6) such that a space (73) exists between a lower end (20A) of the at least one baffle member (2A) and a floor surface (68) of the building (6).
[0207] The environment control system (2) according to the fourteenth aspect can narrow the space (73) between the lower end (20A) of the at least one baffle member (2A) and the floor surface (68), and therefore the wind velocity of air can be increased when the air flows through the space (73).
