In the present application, an air conditioner performs a refrigeration cycle of an indoor unit of the air conditioner by using a compressor, a condenser, an expansion valve, and an indoor heat exchanger. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged. The compressor compresses a refrigerant gas in a low-temperature and low-pressure state and discharges the refrigerant gas in a high-temperature and high-pressure state. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the ambient environment through the condensation process. The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The indoor heat exchanger evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The indoor heat exchanger may achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioning indoor unit can adjust the temperature of the indoor space throughout the cycle. The outdoor unit of the air-conditioning indoor unit refers to a portion of the refrigeration cycle that includes the compressor and the outdoor heat exchanger, the indoor unit of the air-conditioning indoor unit includes the indoor heat exchanger, and the expansion valve may be provided in either the indoor unit or the outdoor unit. The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an indoor heat exchanger.
