Detailed Description

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

In the present application, the air-conditioning cabinet performs a refrigeration cycle of the air-conditioning cabinet 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 in a low-temperature and low-pressure state, and discharges a compressed high-temperature and high-pressure 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 the medium-temperature and high-pressure state condensed in the condenser into a low-temperature and 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. Throughout the cycle, the cabinet may regulate the temperature of the indoor space.

The cabinet includes a cabinet indoor unit and a cabinet outdoor unit, the outdoor unit includes a compressor and an outdoor heat exchanger, the cabinet indoor unit includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner cabinet is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner cabinet is used as a cooler in a cooling mode.
