The condenser condenses the compressed high-temperature and high-pressure gaseous refrigerant into a liquid refrigerant, and heat is released to the surrounding environment through the condensation process.

The liquid refrigerant flowing out of the condenser enters an expansion valve, and the expansion valve expands the liquid refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid refrigerant. The low-pressure liquid refrigerant flowing out of the expansion valve enters the evaporator, and when the liquid refrigerant flows through the evaporator, the heat absorbed by the liquid refrigerant evaporates into low-temperature low-pressure refrigerant gas, and the refrigerant gas in a low-temperature low-pressure state returns to the compressor. The evaporator may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. The evaporator can regulate the temperature in the temperature controlled zone throughout the cycle.
