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 heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator.
