Air conditioners are based on the principles of evaporation and condensation and then compression and expansion. The hot air of the car is removed by the process of evaporation and then the condensation of the evaporated air takes places which is then further compressed by the compressor and then finally expanded to us in the form of cold breeze. Somehow, Air conditioning reduces the average of the car, as the energy is required to remove the hot air and then compression and expansion.

Automotive air conditioning is done to control the temperature, humidity, purity of the atmospheric of the air and circulate the same in the automobile to make the journey of passengers comfortable so that they Should not feel too much cold in winter and too hot in summers. Earliest, most of cars were having the cooling provision only as shown in Figure. It consists of refrigeration system, an air circulation and distribution system and a control system as shown in the layout. It includes the compressor, condensor, dehydrator and connecting lines in addition to expansion valve, orifice tube, suction throttle valve and high pressure cut off  switch. The commonly used refrigerant is freon 12 . The compressor driven by a belt from the engine pulley through an electromagnetic clutch sucks the low temperature and low pressure refrigerant vapour from the evaporator ad compresses it to high temperature and high pressure vapor. Then it is discharged to the condenser Air is caused to flow a...
