1 After starting the air conditioning system according to the operation procedure, the compressor starts to work under the drive of the engine, and drives the refrigerant (R134a, an environmentally friendly refrigerant, which will not damage the ozone layer, non-toxic, non-irritating, non-combustion, non-corrosive) to circulate in the sealed air conditioning system. The compressor compressors the gaseous refrigerant into high temperature and high pressure refrigerant gas and then exits the compressor.


2 High temperature and high pressure refrigerant After the air flows into the condenser through the pipe, it dissipates heat and cools down in the condenser, and the liquid refrigerant condensed into high temperature and high pressure flows out.


3 The high-temperature and high-pressure liquid refrigerant enters the dry liquid reservoir through pipes and flows into the expansion valve after drying and filtering.


4 The high temperature and high pressure liquid refrigerant is throttled by the expansion valve, and its state changes rapidly, becoming the low temperature and low pressure liquid refrigerant.


5 Low temperature and low pressure liquid refrigerant immediately enters the evaporator, absorbs the air heat flowing through the evaporator in the evaporator, reduces the air temperature, blows out the cold wind, produces the refrigeration effect, the refrigerant itself because of the absorption of heat and evaporates into low temperature and low pressure gaseous refrigerant.


6 Low temperature and low pressure gaseous refrigerant is sucked into the compressor through the pipe, compressed, and enters the next cycle. As long as the compressor continues to work, the refrigerant will continue to cycle in the air conditioning system, producing refrigeration effect; When the compressor stops working, the refrigerant in the air conditioning system stops flowing and does not produce refrigeration effect.
