How does car air conditioning cool?

Auto air conditioning refrigeration is to refrigerant as a heat carrier through the refrigeration cycle for refrigeration and dehumidification. Automotive air conditioning refrigeration mainly through the following processes: 1, the compressor will be sucked back from the evaporator refrigerant pressurization, in order to increase the temperature of the refrigerant, and the refrigerant into a high temperature and high pressure vapour refrigerant. 2, high temperature and high pressure vapour refrigerant into the condenser, due to the temperature is higher than the outside ambient temperature, so want to the environment to dissipate the heat, will be changed into a medium-temperature, high-pressure liquid refrigerant. 3, medium-temperature, high-pressure liquid refrigerant Out of the condenser into the liquid storage dryer for filtration and water absorption, while part of the refrigerant stored here. 4, after filtering the refrigerant through the throttle device, decompression. At this time the refrigerant is low temperature and low pressure liquid refrigerant. 5, low temperature and low pressure liquid refrigerant into the evaporator. As the space in the evaporator suddenly increased to make the pressure decrease, the refrigerant at this time the pressure is lower temperature is lower, due to much lower than the ambient temperature, so absorb the ambient temperature so that the refrigerant vaporization at the same time will pass through the evaporator outside the air cooled down, through the blower into the car compartment. 6, at this time, the air conditioning and refrigeration system to complete a refrigeration cycle. Refrigeration system week after week so that the refrigerant cycle to achieve the purpose of refrigeration.
