BACKGROUND
[002] The 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] An air-conditioned environment is important to personal comfort and even health. Generally, most of the vehicles are equipped with air-conditioning systems. Vehicle air conditioning system provides a relaxed and fatigue free atmosphere to humans which in turn provides comfort, which is essential for health of occupants/passenger. Passengers have to face lots of traffic that causes slow motion of vehicle due to which it is essential for a vehicle to be equipped with a system that can provide comfort for the passengers. In India, during summers there is lots of hot and humid air in atmosphere which causes difficulty for a driver to drive and also for passengers to travel, so during summer an effective air conditioning system is required in a vehicle which can provide a cool and humid free environment inside a passenger’s compartment. Air conditioning does not only condition the environment inside a passenger’s cabin of the vehicle but also provide filtered air which is very essential in cities due to very hazardous air pollution condition that can cause health issues to passengers.
[004] In conventional air conditioning system of the vehicle, since compressor is driven by vehicle engine, if the vehicle is stopped at a traffic signal or the like, each time the vehicle engine is stopped, compressor is also stopped, thereby decreasing comfort of passengers. Also, power consumption by an existing air conditioner is high, making it more costly and less efficient. Besides, the conventional air conditioning system requires more space for installation.
[005] Efforts have been made in the past to overcome problem associated with the conventional air conditioners. However, existing techniques increases humidity in the automobile, and may even need large space for installing an air conditioner.
[006] There is, therefore, a need in the art to provide an improved air conditioner for a vehicle that overcomes the above-mentioned limitation of the conventional air conditioning system and other limitations of the existing solutions and utilize techniques, which are robust, accurate, fast, efficient, cost-effective and simple.

Moreover, an output end of the condenser 118 can be connected to an input end of the expansion valve 120 with the flexible refrigerant hose, and an output end of the expansion valve 120 can be connected to an input end of the evaporator unit 114 with the flexible refrigerant hose.
[0040] In an embodiment, power of the vehicle can be used for charging rechargeable batteries 110 of the portable air conditioning unit 100 to provide uninterrupted power supply to air conditioner unit 100.
[0041] In an embodiment, the evaporator 114 can be configured for cooling vehicle's hot air received into the housing into cold air with assistance of refrigerant flowing through the evaporator.
[0042] In an embodiment, the input end of the compressor 116 is connected with evaporator unit 114, and output end of compressor 116 is connected with the condenser unit 118, where the compressor 116 and the evaporator unit 114 is operatively coupled with the flexible refrigerant hose to enable a flow of refrigerant.
[0043] In an exemplary embodiment, when the compressor 116 starts, it draws in cold refrigerant gas in liquid form as it leaves the evaporator unit 114. In an exemplary embodiment, air conditioners use a type of refrigerant gas that turns into a liquid at very cold temperatures: -15.9 degrees Fahrenheit (-26.6 degrees Celsius). The compressor 116 increases pressure of the refrigerant gas while compressing it, as the gas is compressed, its temperature goes up. The compressor 116 pushes out hot, compressed refrigerant gas through output end of compressor 116 and allows it to enter in the condenser unit 118 through flexible refrigerant hose.
