The refrigeration principle of parking air conditioning is similar to that of ordinary air conditioning, which mainly relies on the circulation of refrigerant to achieve.
First, the compressor inhales and compresses the low-temperature and low-pressure gaseous refrigerant to turn it into a high-temperature and high-pressure gaseous refrigerant.
Then, the high temperature and high pressure gaseous refrigerant passes through the condenser, in which the heat is exchanged with the outside air, the refrigerant dissipates heat and gradually condenses into the liquid refrigerant of high temperature and high pressure.
Then, the liquid refrigerant passes through the throttling device (such as an expansion valve or capillary), the pressure and temperature are sharply reduced, and the liquid refrigerant becomes low temperature and low pressure.
Finally, the low-temperature and low-pressure liquid refrigerant enters the evaporator, absorbs the heat in the evaporator and evaporates, thus reducing the air temperature in the car and achieving the effect of refrigeration. The low temperature and low pressure gaseous refrigerant after evaporation is again inhaled by the compressor to start a new cycle.
The whole cooling process through the continuous circulation of the above steps, continue to take away the heat in the car, to achieve the cooling effect in the car when parking.
