The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, 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 in a high-temperature and high-pressure state 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 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 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. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

The air conditioner includes an indoor air conditioner and an outdoor air conditioner, the outdoor air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor or outdoor unit. The indoor unit of the air conditioner is connected to an outdoor unit installed in an outdoor space through a pipe. The outdoor unit may be provided with a compressor, an outdoor heat exchanger, an outdoor fan, an expander, and the like of a refrigeration cycle, and the indoor unit may be provided with an indoor heat exchanger and an indoor fan.
