The refrigerating cycle and the heating cycle include a compression process, a condensation process, an expansion process and an evaporation process, and cold or heat is provided to the indoor space through the heat absorption and release processes of the refrigerant, so that the temperature of the indoor space is adjusted.

The compressor compresses refrigerant gas that is formed in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed high-temperature and high-pressure gaseous refrigerant into a liquid refrigerant, and the heat is released to the surrounding environment through the condensation process.

The liquid refrigerant flowing out of the condenser enters an expansion valve, which 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 11, absorbs heat when the liquid refrigerant flows through the evaporator 11 and evaporates into low-temperature and low-pressure refrigerant gas, and the refrigerant gas in a low-temperature and low-pressure state is returned to the compressor. The evaporator 11 may achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner 100 can adjust the temperature of the indoor space throughout the cycle.
