Composed of 1 air conditioning system air conditioning system consists of compressor, condenser, evaporator, expansion valve, dry reservoir and pipeline etc,
2 refrigeration principle
1) after the user profile according to the operation procedures to start the car air conditioning system, the compressor starts to work under the drive of the engine, drive the refrigerant (R134a, a kind of environment-friendly refrigerant, not the destruction of the ozone layer, non-toxic, no stimulation, no burning, no corrosive) circulating in the air conditioning system in a sealed compressor, refrigerant gas compressor will discharge gaseous refrigerant compressed into high temperature and high pressure.
2) high temperature and high pressure refrigerant gas pipeline into the condenser, the condenser cooling, cooling, condensing into liquid refrigerant high temperature and high pressure flow
.3) high temperature high pressure liquid refrigerant through the pipeline into the dry reservoir, dried and filtered into the expansion valve.
4) high temperature high pressure liquid refrigerant by Bentonite The expansion valve throttling, the state changed into liquid refrigerant of low temperature and low pressure.
5) at low temperature and low pressure liquid refrigerant into the evaporator immediately, the air flows through the evaporator to absorb heat in the evaporator, the air temperature is lower, the cold wind is blown out, produce the cooling effect, the refrigerant itself due to heat absorption and evaporation into the gaseous refrigerant of low temperature and low pressure
6). Low temperature and low pressure gaseous refrigerant through the pipeline compressor suction, compression, and enter the next cycle, as long as the compressor working continuously, continuous cycle refrigerant in the air-conditioning system, produce the cooling effect; the air compressor stops working, then stop the flow of refrigerant in the air-conditioning system, does not produce the cooling effect.
