The refrigeration cycle includes a series of processes involving compression, condensation, throttling, and evaporation, and supplies cold or heat 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 throttles the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser to a low-pressure gas-liquid two-phase refrigerant. In the evaporator, the refrigerant expanded in the expansion valve absorbs heat and evaporates, and then is in a low-temperature and low-pressure state, and then the refrigerant gas is returned to the compressor. The evaporator may achieve a cooling effect by exchanging heat with a material to be cooled using the latent heat of evaporation of the refrigerant. The air conditioning indoor unit can adjust the temperature of the indoor space throughout the cycle. The outdoor unit of the wall-hung air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the wall-hung air conditioner 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 may be used as a condenser or an evaporator, respectively.
