Detailed Description

The present invention is specifically described below by way of exemplary embodiments. It should be understood, however, that elements, structures, and features of one embodiment may be beneficially incorporated in other embodiments without further recitation.

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 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 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. 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 is a part 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 air conditioner or the outdoor air conditioner.
