The refrigeration cycle is a series of processes consisting of compression-condensation-expansion-evaporation, and hot air exchanges heat with a low-temperature refrigerant before supplying low-temperature air to the room.

The compressor compresses and discharges the refrigerant gas in a high-temperature and high-pressure state, and the discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase and releases heat to the surroundings through the condensation process. The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into the low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve. The evaporator uses the latent heat of evaporation of the refrigerant to achieve a refrigeration effect by heat exchange with the object to be cooled, and returns the refrigerant gas in the low-temperature and low-pressure phase to the compressor. Through this cycle, the air temperature of the indoor space can be controlled.
