Specifically, the air conditioner of the present application is used in combination with an outdoor unit, wherein the heat exchanger may be an evaporator or a condenser, and the heat exchanger in the outdoor unit is a condenser or an evaporator, and the air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, an expansion valve, a condenser, and an evaporator. 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 and discharges the compressed refrigerant gas. 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 evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor.
