[0039] In the present application, the air conditioner performs the refrigeration cycle of the indoor 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 the 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 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 can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the whole cycle, the indoor air conditioner can adjust the temperature of the indoor space. The outdoor unit of the indoor air conditioner refers to a part of the refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the indoor air conditioner includes an indoor heat exchanger, and the 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. When the indoor heat exchanger functions as a condenser, the indoor air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an indoor heat exchanger, the indoor air conditioner functions as a cooler in a cooling mode.
