In the present application, the air conditioning indoor unit performs a refrigeration cycle of an air conditioning case 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 a refrigerant to the air that has been conditioned and heat exchanged. The compressor compresses refrigerant gas in a low-temperature and low-pressure state and discharges 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 heat is released to the surrounding 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 exchanging heat with a material to be cooled using latent heat of vaporization of a refrigerant. The air conditioning case can adjust the temperature of the indoor space throughout the cycle. The outdoor unit of the air conditioner case refers to a portion of the refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner case includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit. The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an indoor heat exchanger.
