, Description:TECHNICAL FIELD
Present disclosure in general relates to a field of automobile engineering. Particularly, but not exclusively, the present disclosure relates to Heating, Ventilation and Air Conditioning (HVAC) system of a vehicle. Further embodiments of the disclosure disclose a method and system for cooling the cabin of the vehicle in an effective and efficient manner.

BACKGROUND OF THE DISCLOSURE

Generally, vehicles such as, but not limited to, passenger vehicles such as cars, sports utility vehicles, multiutility vehicles, and commercial vehicles like trucks or buses may be employed with Heating, Ventilating and Air Conditioning (HVAC) systems. These HVAC systems provide comfortable climatic conditions within a cabin of the vehicle. HVAC systems may help in managing required degree of hotness or coolness in the cabin of the vehicle based on requirement and for the comfort of the passengers.

In certain conditions, the vehicles parked or operating in hot environmental conditions, may be subjected to high heat loads due to solar radiation, humidity and other environmental factors. The heat loads acting on the vehicle may result in temperature rise within the cabin of the vehicle. This temperature rise is more, when the vehicle is parked in open space under the sun, also termed as hot soak condition of the vehicle. This hot soak condition of the vehicle increases load on a compressor of an air conditioning unit. The air conditioning unit of the HVAC system, operating in the vehicle subjected to high heat loads, may require longer time duration to cool the cabin of the vehicle. Hence, the air conditioning unit may fail to provide instantaneous cooling and quick chilling effect inside the cabin. Additionally, load on the compressor of the air conditioning unit may lead to excessive fuel consumption, and thus leads to more emissions.

With advancement in technology, continuous improvements in increasing the performance and effectiveness of the air conditioning unit in a hot soak vehicle are being carried out. One such improvement is to increase the size of the evaporator, condenser, compressor and the like of the air conditioning unit, which may result in improving the performance of the air conditioning unit. However, the upsizing of components size may result in putting more load on the compressor, therein leading to higher fuel consumption and compromised vehicle performance. Furthermore, the air conditioning unit with such configuration may be bulky and may lead to space constraints within the engine bay of the vehicle. The bulky air conditioning units may also consume excess fuel, affecting performance of the engine and increases emission.

With the ongoing efforts, the air conditioning unit of the HVAC system in vehicle are configured such that they may be remotely activated to cool the cabin of the vehicle, prior to occupants/passengers entering the vehicle, to experience chilling effect upon entering the vehicle. However, such technique may further result in consumption of excess fuel and increase in emissions, as the air conditioning unit runs on engine power. Additionally, the conventional techniques of cooling the cabin solely rely only on the air conditioning unit, which again leads to consumption of excess fuel, which increase emissions.

The present disclosure is directed to overcome one or more limitations stated above and any other limitations associated with the prior arts.

In the Figures, the same element or elements which have same functions are indicated by the same reference signs. One skilled in the art would appreciate that the method, and the system as disclosed in the present disclosure can be used to provide effective and efficient cooling effect such as but not limiting to a cabin of a vehicle.

Embodiments of the present disclosure disclose a system and method for cooling a cabin of a vehicle. Generally, vehicles parked or operating in hot conditions may be subjected to high heat loads due to solar radiation, humidity and other environmental factors. As a result of this, there may be a sharp rise in temperature of the cabin, causing inconvenient to the passengers or occupants. To improve the comfort to the occupants of the vehicles, air conditioning unit of a HVAC system may be employed in the vehicle. The air conditioning units may facilitate in cooling the cabin i.e. to reduce temperature of the cabin. However, due to high cabin temperature, the air conditioning unit may fail to cater to effective cooling effect, due to increase in load on the compressor of the air conditioning unit. This limitation of the air conditioning unit may cause discomfort to the user. Further, high loads on the compressor, may result in excessive fuel consumption, which may lead to more emissions.
The system of the present disclosure includes a Heating, Ventilation and Air Conditioning (HVAC) system. An Air Conditioning (AC) unit of the HVAC system in the vehicle, may be adapted to cool the cabin of the vehicle. Further, the system includes a blower, which may be configured to selectively operate in a fresh mode and a recirculating mode. In an embodiment, the blower may be connected to a battery unit of the vehicle. Furthermore, the system may include at least one sprayer, configured to spray coolant at predefined intervals of time onto a condenser of the AC unit. Additionally, the system includes at least one Electronic Control Unit (ECU), configured to control operations of components of the system. The ECU may be configured to receive an input signal from a signal module transmission, activated by the user. Upon receiving the input signal, the ECU may be configured to receive a temperature value of the cabin from at least one sensor positioned in the cabin. Further, the ECU may be configured to compare the temperature value of the cabin with a predefined temperature (i.e., optimal temperature at which the cabin needs to be maintained). Furthermore, the ECU may be configured to activate the blower, selectively in the fresh mode with simultaneously lowering down the vehicle windows and the recirculating mode, based on the comparison of the temperature value of the cabin with the pre-defined temperature. Additionally, the ECU may be configured to detect a command to operate the AC unit, and activate the at least one sprayer, to spray coolant onto the condenser of the AC unit at predefined intervals of time.

In a method of operation, the system is devised to cool the cabin of the vehicle. An input signal from a signal transmission module, which is actuated by the user, may be transmitted to the ECU. Upon receiving the input signal from the signal transmission module, the ECU may receive the temperature value of the cabin via at least one sensor positioned in the cabin. In an embodiment, the at least one sensor may be a temperature sensor. Upon receiving the temperature value of the cabin, the ECU may compare the temperature value of the cabin with the predefined temperature. Based on the comparison of the temperature value of the cabin with the predefined temperature, the ECU may activate the blower in either the fresh mode or the recirculating mode. As an example, the blower may be activated in the fresh mode, when the temperature value of the cabin is above the predefined temperature. Further, the blower may be activated in the recirculating mode, when the temperature value of the cabin is below the pre-defined temperature. Furthermore, the ECU may also send a signal to lower down the vehicle windows, when the temperature value of cabin is above the predefined temperature. In an embodiment, the blower activated in the fresh mode and simultaneously lowering down the vehicle windows may facilitate in flushing out hot air from the cabin into the atmosphere, to reduce the temperature of the cabin, and the blower activated in the recirculating mode may facilitate in circulating the air within the cabin, without letting the air to pass into the atmosphere, unlike the fresh mode of the blower.

The ECU may detect the command to operate the AC unit, i.e., the ECU may receive a signal upon detecting ON condition of the AC unit, which in general is operated by a user upon starting the vehicle. Upon detection of the command to operate the AC unit, the ECU may activate the at least one sprayer to spray coolant onto the condenser of the AC unit at predefined intervals of time in order to increase efficiency of the condenser.

In an embodiment, adapting the system and the method of the present disclosure may provide effective cooling in the cabin, and thus, provides comfort and convenience for the occupants inside the hot soaked vehicle.
In the following detailed description, embodiments of the disclosure are explained with reference of accompanying figures that form a part hereof, and in which are shown by way of illustration specific embodiments in which the disclosure may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the disclosure, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present disclosure. The following description is, therefore, not to be taken in a limiting sense.
Figure 1, illustrates a system (100) for cooling a cabin of a vehicle. The system (100) includes a Heating, Ventilation and Air Conditioning (HVAC) system (not shown in figures). The HVAC system may be adapted to perform heating or cooling the cabin of the vehicle, based on the requirement. In an embodiment, an Air Conditioning (AC) unit (106) of the HVAC system of the vehicle, may be adapted to cool the cabin of the vehicle to a desired temperature by the user. The system (100) also comprises a blower (105), which may be selectively configured to operate in two modes i.e. in a fresh mode and a recirculating mode. In an embodiment, the blower (105) operating in the fresh mode may facilitate in flushing out air inside the cabin to the atmosphere, through windows of the vehicle or any other openings in the vehicle, and the blower (105) while operating in the recirculating mode, may facilitate in circulating the air within the cabin, unlike the fresh mode. Further, the system (100) includes at least one sprayer (107) that may be located in an engine bay (not shown in figures) of the vehicle proximal to a condenser (108) of the air conditioning unit (106). The at least one sprayer (107) may be configured to spray coolant at predefined intervals of time onto the condenser (108) of the AC unit (106). Additionally, the system (100) comprises an Electronic Control Unit (ECU) (102), that may be configured to control operations of various components of the system (100). The ECU (102) may be configured to receive an input signal from a signal transmission module (101), associated with the vehicle. In an embodiment, the signal transmission module (101) may be a key fob. As an example, a button configured on the key fob, may be operated by the user, to transmit an input signal to the ECU (102), for initiating cooling of the cabin. In an embodiment, the input signal to the ECU (102) via the signal transmission module (101) may be a wireless signal, which may be provided remotely (i.e., at a distance from the vehicle), by the user. In another embodiment, the input signal to the ECU (102) via the signal transmission module (101) may be provided by the user, seated within the cabin of the vehicle.
Upon receiving the input signal from the signal transmission module (101), the ECU (102) may receive a temperature value of the cabin from at least one sensor (103) positioned in the cabin. In an embodiment, the at least one sensor (103) may be a temperature sensor. Further, the ECU (102) may be configured to compare the temperature value of the cabin with predefined temperature. As an example, the predefined temperature may be set based on the comfort and convenience of the users. Based on the comparison of the temperature value of the cabin with the predefined temperature, the ECU (102) may be configured to activate the blower (105), selectively in the fresh mode and the recirculating mode. In some embodiments, the ECU (102) may be configured to operate a window regulator (104) associated with windows of the vehicle. As an example, the ECU (102) may be configured to operate the window regulator (104) to roll down windows of the vehicle or lock the windows in roll down condition, when the blower (105) is activated in fresh mode to facilitate in flushing the air inside the cabin to the surroundings. The ECU (102) may also be configured to operate the window regulator (104) to roll up the windows or lock the windows in roll up condition, when the blower (105) is activated in the recirculating mode.
In an embodiment, the ECU (102) may be configured to detect a command to operate the AC unit (106), i.e. to detect ON condition of the AC unit (106). Upon detecting a command to operate the AC unit (106) or when the ECU (102) detects ON condition of the AC unit (106), the ECU (102) may activate the at least one sprayer (107), to spray coolant onto the condenser (108) of the AC unit (106) at predefined intervals of time. In some embodiments, spraying the coolant onto the condenser (108) may facilitate in increasing subcooling of the refrigerant and, thus facilitates in providing effective cooling inside the cabin.
In an embodiment, operating the blower (105) to initially flush out the hot air from the cabin may substantially decrease the temperature of the cabin, before activation of the AC unit (106) of the HVAC system. This facilitates in decreasing load on the AC unit (106) and thus facilitates in catering instantaneous cooling in the cabin. In addition, spraying coolant onto condenser (108) at predefined intervals of time facilitates in effective cooling of the refrigerant, and thus reduces load on the condenser (108) of the AC unit (106). In some embodiments, spraying coolant onto the condenser (108) only at predefined intervals of time may facilitate in effectively utilizing effects of the coolant sprayed onto the condenser (108) and, also facilitate in minimizing the quantity of coolant sprayed onto the condenser (108).
In an embodiment, the cabin of the vehicle may be provided with one or more insulation layer (not shown in figures). As an example, the one or more insulation layers may be installed on roof, body panels, roof and the like of the cabin. The one or more insulation layers may facilitate in reducing heat transfer into the cabin of the vehicle. Thus, the one or more insulation layers may facilitate in reducing heat load on the cabin, and thus aids in cooling the cabin of the vehicle under hot soak conditions at a faster rate.
Figure. 2 is an exemplary embodiment of the present disclosure which illustrates a flow chart, depicting a method for cooling the cabin of the vehicle. In the present disclosure, the cabin of the hot soaked vehicle may be cooled effectively in an efficient and effective way. The method is now described with reference to the flowchart blocks and is as below. The order in which the method is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method. Additionally, individual blocks may be deleted from the methods without departing from the scope of the subject matter described herein.
At block 201, the method includes receiving by the ECU (102), the input signal from the signal transmission module (101). In an embodiment, the signal transmission module (101) may be a key fob, which may be operated by the user. As an example, the input signal may be provided by the user remotely or from within the cabin of the vehicle.
At block 202, upon receiving the input signal from the signal transmission module (101), the ECU (102) may receive temperature value of the cabin from at least one sensor (103). Further, the ECU (102) compares the temperature value of the cabin with the predefined temperature [shown in block 203]. Based on the comparison of the temperature value of the cabin with the predefined temperature, the ECU (102) may activate the blower (105) selectively to operate in the fresh mode or the recirculating mode. In an embodiment, the ECU (102) may activate the blower (105) in the fresh mode, when the temperature value of the cabin is above the predefined temperature [shown in block 205], and the ECU (102) may activate the blower (105) in the recirculating mode, when the temperature value of the cabin is below the predefined temperature [shown in block 206]. As an example, when the temperature value of the cabin is above the pre-defined temperature, the ECU (102) may activate the blower (105) in the fresh mode to flush out hot air from inside the cabin, to reduce the temperature of the cabin. Upon activation of the blower in fresh mode, the ECU (102) may continuously receive temperature values of the cabin from the at least one sensor (103), and compare the received temperature value with the pre-defined temperature. Once the temperature value of the cabin reduces below the pre-defined temperature, the ECU (102) may activate the blower (105) in the recirculating mode.

In some embodiments, the ECU (102) may be configured to operate the window regulator (104). The ECU (102) may operate the windows to roll down or keep in roll down condition, when the blower (105) is activated in the fresh mode, to facilitate flushing of hot air in the cabin into the surroundings [shown in block 204]. Flushing the air into the surroundings from the cabin may facilitate in reducing the temperature of the cabin and thus, cooling the cabin. Further, the ECU (102) may operate the windows to roll up or keep in roll up condition, when the blower (105) is activated in the recirculating mode.

At block 207, the method includes a step of detecting by the ECU (102) a command to operate the AC unit (106) of the HVAC system i.e. ON condition of the AC unit (106). In an embodiment, the command to operate the AC unit (106) may be provided by the user. Upon detecting the command to activate the AC unit (106), the ECU (102) may activate the at least one sprayer (107) to spray coolant on to the condenser (108) of the AC unit (106) at predefined intervals of time [shown in block 208]. In an embodiment, the coolant sprayed onto the condenser (108) may be received from the AC unit (106). As an example, the coolant may be, but not limiting to condensed water, received from the air conditioning unit (106). In some embodiments, the predefined intervals of time for spraying the coolant on to the condenser (108) may be for about 13 to 15 seconds, once the AC unit (106) is ON condition for about 10 to 12 seconds in a first interval of time. Further spraying of the coolant may take place for about 8 to 12 seconds, after the AC unit (106) is in ON condition for about 180 to 190 seconds, in a second interval of time. In an embodiment, the at least one sprayer (107) may be activated for about 13 seconds, once the AC unit (106) is in ON condition for 10 seconds, in the first interval of time, and for about 8 seconds once the AC unit (106) is in ON condition for 180 seconds, in the second interval of time. In an embodiment, spraying the coolant onto the condenser (108) only at predefined intervals of time may facilitate in minimizing the amount of coolant being sprayed onto the condenser (108) and utilizing the after effects of the coolant sprayed in an effective and efficient way.

In an embodiment, the system (100) and method of the present disclosure may facilitate in reducing temperature of cabin of the vehicle (i.e. cooling the cabin) before the occupants board the vehicle. This facilitates in cooling of the cabin initially (i.e. without the AC unit (106) being operated), and thus mitigates the chances of discomfort to the user or the passengers boarding the vehicle under hot soak condition. Further, this step of cooling the cabin before the occupants enter the vehicle cabin assists the AC unit (106) to cater effective cooling. Further, spraying coolant onto the condenser (108) of the AC unit (106), may facilitate in improving effectiveness and efficiency of the AC unit (106), as the coolant facilitates in increased subcooling of the refrigerant.

In some embodiments, when the temperature of the cabin is initially, below the predefined temperature, upon comparison of the temperature value of the cabin with the pre-defined temperature, the ECU (102) may activate the blower (105) directly in the recirculating mode, with the windows held in roll up condition.

In an embodiment, the ECU (102) may be configured to activate the at least one sprayer (107) independent of the temperature value of the cabin.

In an embodiment, comparing the temperature value of the cabin with the pre-defined temperature, by the ECU (102) may not be construed as limitation, as the comparison may be made vice-versa.
