The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant to the air that has been conditioned and heat exchanged.

The compressor compresses refrigerant gas in a low-temperature and low-pressure state and discharges 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 heat is released to the surrounding environment through the condensation process.

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 may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant.

The air conditioning indoor unit can adjust the temperature of the indoor space throughout the cycle. The outdoor unit of the air conditioner indoor unit refers to a portion of the refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner 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 function as a condenser or an indoor heat exchanger. When the indoor heat exchanger is used as a condenser, the air-conditioning indoor unit is used as a heater for a heating mode, and when the indoor heat exchanger is used as an indoor heat exchanger, the air-conditioning indoor unit is used as a cooler for a cooling mode.

The first inner cavity and the second inner cavity are mutually communicated, the indoor air inlet 101 is communicated with the first inner cavity, and the indoor air outlet 102 is communicated with the second inner cavity.

The length direction of the first inner cavity is the same as the length direction of the housing 100, and the length direction of the second inner cavity is the same as the length direction of the housing 100.

In some embodiments, the air conditioner may be installed at the top of the room, the thickness direction of the housing 100 is disposed in the vertical direction, the indoor air inlet 101 is disposed downward, and the indoor air outlet 102 is disposed in the horizontal direction. The air conditioner can also be installed on a wall, the height direction of the shell 100 is set along the vertical direction, the indoor air outlet 102 is set up upwards, the indoor air inlet 101 is set along the horizontal direction, and the second inner cavity is located above the first inner cavity.

While embodiments of the present utility model have been shown and described above, it will be understood that the above embodiments are illustrative and not to be construed as limiting the utility model, and that variations, modifications, alternatives and variations may be made to the above embodiments by one of ordinary skill in the art within the scope of the utility model.
