[0064] In the present application, the air conditioner indoor unit performs a refrigeration cycle of the air conditioner indoor unit 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 conditioned and heat-exchanged air.

[0065] The compressor compresses the refrigerant gas at low temperature and low pressure and discharges the refrigerant gas at high temperature and high pressure. The discharged refrigerant gas flows into the condenser.

The expansion valve expands the liquid phase refrigerant at high temperature and high pressure condensed in the condenser into a low pressure liquid phase refrigerant.

[0066] 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.

[0067] In the whole cycle, the air conditioner indoor unit can adjust the temperature of the indoor space. The outdoor unit of the air conditioner indoor unit refers to the part of the refrigeration cycle including the compressor and the outdoor heat exchanger, the indoor unit of the air conditioner indoor unit includes the indoor heat exchanger, and the expansion valve can be provided in the indoor unit or the outdoor unit.

[0068] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an indoor heat exchanger.
