The present subject matter described herein, relates to the technical field of controlling humidity. The present subject matter, in particularly, relates to a controlling system providing capability to control air flow and compressor frequency for regulating humidity and temperature.
BACKGROUND AND PRIOR ART AND PROBLEM IN PRIOR ART:
[002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[003] Air conditioning and controls for adjusting the air-conditioning equipment, to achieve a desired comfort zone by controlling the temperature and humidity levels, are well known. The conventional air conditioning units are typically operated based on a direct correlation between the opening of a chilled water mixing valve for chilled water units, and the speed of the compressor for direct expansion units, and the difference between the measured supply air temperature and a temperature set point, to enable cooling control.
[004] In addition, humidity gets reduced in conventional residential air conditioning units in fixed proportion of total cooling which is driven by the difference between temperature set point and the measured temperature, which leads to wastage of energy There is no mechanism of controlling quantum of humidity in conventional residential ACs.
[005] Humans are comfortable within a wide range of relative humidity between 30% to 70% depending on the ambient temperature. Very low/high humidity can create discomfort, respiratory problems, and aggravate allergies, etc.
[006] High humidity and low humidity can cause several health related problems. Such as, higher humidity can cause condensation on windows, wet

stains on walls and ceilings, moldy bathrooms, musty odor, and/or clammy feel to the air. People with heart problems or asthma are advised to be extremely careful in high humidity conditions. High humidity can even trigger allergic reactions, contribute to ongoing allergies, and dust mite problems. High humidity makes it easier for molds to reproduce, and they can appear virtually anywhere, damaging whatever they grow upon.
[007] On the other hand, low humidity causes static electricity, dry skin, lips and hair, scratchy throats and noses, and itching and chapping. Mucous membranes in nose and throat dry out, increasing your discomfort and susceptibility to colds and respiratory illness.
[008] It has long been recognized that proper air conditioning systems should not only lower the temperature of the interior space being served when the temperature therein has exceeded a predetermined level but should also control the humidity of the space as a function of the air conditioning.
[009] In general, in conventional residential air conditioner the prime function is to decrease the indoor temperature. It was understood from various studies that approximately 65%~70% of total cooling capacity is used for cooling & 30%~35% of total cooling capacity is used for humidification.
[0010] During this period of time, substantial amount of humidity gets automatically removed from dry air of indoor ambient even if it is not desired. In higher humidity areas, the major amount of total cooling capacity is used for cooling whereas requirement is for dehumidification. Thus creating a very inefficient system. Further, in conventional residential air conditioners, the quantum of humidification cannot be controlled.
[0011] In recent years, some manufacturers have incorporated humidity sensing into their controls. Humidity control has typically been accomplished through adjustment of the temperature set point condition based on a combined temperature-humidity setting, rather than through a control strategy based on user selectable temperature and humidity set points.

[0012] The present invention brings a unique, inventive system using real time humidity sensor system to detect indoor side humidity level and adjust the quantum of humidification accordingly.
[0013] In an object of the present invention, the user will feel the comfort of cooling with respect to both temperature and humidity. An air conditioning system which can sense weather conditions and adjust SHF (Sensible Heat Factor) accordingly so that proper humidity can be maintained in indoor side thus providing a better Human Comfort
[0014] Accordingly, the present invention provides a system capable of minimizing the energy consumption of air conditioning units due to proper dehumidification and an efficient system to regulate the air conditioner for better efficient usage.
[0015] The information disclosed in this background of the disclosure section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

[0035] While the embodiments of the disclosure are subject to various modifications and alternative forms, specific embodiment thereof have been shown by way of example in the figures and will be described below. It should be understood, however, that it is not intended to limit the disclosure to the particular forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternative falling within the scope of the disclosure.

In other words, one or more elements in a system or device proceeded by "comprises... a" does not, without

[0037] The enhancement of the air conditioning unit for adjusting the quantum of humidification by sensing indoor humidity at real-time and maintaining the temperature and humidity is an advantageous object of the present invention.
[0038] Referring to Fig.l, is a view of an air conditioning unit capable of performing control of humidity through controls and connections of a Controlling system according to the invention. The Controlling system includes a control panel and a microprocessor and wiring terminal. Any suitable controlling system, employing a microprocessor, system, or a general purpose computer arranged and operating according to the inventive principles and as would be known to one skilled in the art, may be used.
[0039] The real-time relative humidity sensing system 100 according to the present invention comprising of a compressor 102, a condenser unit 103 connected to the compressor; a controlling system 101 with combination consisting of an outdoor unit controlling system (ODU) and indoor unit (IDU) controlling system. The humidity sensor 104 sends real time or at regular intervals information to controlling system(s) 101 in response to which compressor unit is regulated by the controlling system to a predetermined set of instructions. Thus, an evaporating (air handling unit) 105 coupled to the controlling system manages the output of air flow. The entire system comprising of sensors, controlling system evaporating unit, compressor unit, condenser unit, expansion device forms a system called as air conditioning unit 106.
[0040] According to the inventive principles as disclosed in connection with the preferred embodiment, the temperature detected by temperature sensor and relative humidity detected using relative humidity sensors 104 is controlled in accordance with predetermined set of instructions. The controlling system contains or has provision for connection of temperature and humidity sensors, circuitry and microprocessor to carry out the control sequence and a connection

terminal for transmitting signals to the compressor unit and air conditioning unit and receiving a temperature signal and humidity signal from sensors 104 of Fig. 1.
[0041] The controlling system 101 may be any general or special purpose computer, CPU, or data processor as would be known to those skilled in the art is operable and connected to the humidity sensing system 100.
[0042] The humidity sensing system captures real-time relative humidity levels in the indoor through the humidity sensor 104 and triggers the controlling system to affect the air flowing through the evaporating unit (air handling unit) and the compressor frequency.
[0043] The compressor unit placed proximal to the humidity sensing system is the component in the system that raises the temperature and pressure of the vapor refrigerant that leaves the evaporator coil. It's important that the compressor raises the pressure of the vapor refrigerant so that it creates a pressure difference, the pressure difference is needed in order for the refrigerant to flow.
[0044] High pressure fluids flow towards lower pressure fluid. Basically the compressor is raising the pressure of the refrigerant so that the refrigerant will flow to the lower pressure refrigerant in the evaporator coil.
[0045] The compressor is the heart of the cooling cycle. The cycle begins when the compressor draws in cool, low-pressure refrigerant gas from the indoors. The motor-driven compressor's sole function is to "squeeze" the refrigerant, raising its temperature and pressure so that it exits the compressor as a hot, high-pressure gas.
[0046] The compressor frequency thus when regulated affects the energy consumption and in turn the efficiency of the entire air conditioning unit. In the present invention, the controlling system when controls this compressor frequency in response to the real-time trigger received from humidity sensor is an object providing merits to the invention over prior art.
[0047] As known in the state of art, the compressor is connected to the unit condensing unit, expansion device, hot and cold coils, deliberating mechanism of

transferring high pressure hot gas and accepting low pressure cold gas, evaporating unit (air handling unit). The working of the compressor unit directly affects the air conditioning unit and its functioning.
[0048] In the present invention, the controlling system is capable of sending pre-defined instructions to the compressor to regulate its frequency. These pre-defined instructions consist of commands wherein, at a particular level of relative humidity how much shall be the compressor frequency and fan speed.
[0049] The pre-defined or pre-determined set of instructions are hard coded in the processors of the controlling system. Once the humidity sensors detect a certain percentage of humidity and temperature sensors detects the temperature, the sensors send a trigger message to the controlling system. The controlling system in return compares the humidity and temperature level with the hard coded predetermined set of instructions and accordingly regulates the functioning of the compressor. The regulation of compressor unit affects the air conditioning unit and the speed of air moving through the air conditioning unit.
[0050] The controlling system based on the pre-determined set of instructions, affects the air flow via the evaporating unit (air handling unit) coupled to controlling system. The evaporating unit (air handling unit) consists of vents, louvers or guides coupled with motor driven mechanism to deliver the air to the conditioned space (room). The controlling system capability to command the compressor thus introducing variations in the air flow in the evaporating unit generates the variations in humidity levels of output for the evaporating unit (air handling unit).
[0051] In an embodiment of the invention, the controlling system introduces variations in the speed of air moving through the evaporating unit and adjust compressor frequency which decreases huge amount of humidity or decreases proportionally less amount of humidity of the output air from the evaporating unit (air handling unit) corresponding to the adjustments in the compressor frequency and variations introduced in the speed of air.

[0052] In another embodiment of the invention, the controlling system initiates variation in the speed of air moving through the evaporating unit and adjusting the compressor frequency accordingly, which either decreases huge amount of humidity or decreases proportionally less amount of humidity of the output air exiting from the evaporating unit (air handling unit) than the external environment.
[0053] In the present invention, the user can override the humidity sensors and instead vary the humidity level based on fixed logic to perform the operations accordingly.
[0054] The main aspect of the invention remains that the controlling system capability to control the compressor frequency and output air flow reduces energy consumption regulates efficient performance of said air conditioning unit and provides ambient humidity levels by decreasing the humidity in desired ratio.
[0055] The invention performs an inventive task of detecting real-time relative humidity levels and basis of which regulates the operations of the air conditioning unit by varying the air flow and adjusting the compressor frequency in areas/zones with low or high humidity.
