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 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 air conditioner indoor unit and an air conditioner outdoor unit, the air conditioner outdoor unit is a part of a refrigeration cycle including a compressor and an outdoor heat exchanger, the air conditioner indoor unit includes an indoor heat exchanger, and an expansion valve may be provided in the air conditioner indoor unit or the air conditioner outdoor unit.

In some embodiments, the flow guiding module 6 may have a "V" shape, that is, the flow guiding module 6 omits the structure of the adaptor 61, and includes only a first flow dividing portion 621 communicating with the first communication port 1311, and a second flow dividing portion 622 communicating with the second communication port 1312. The lower ports of the first branch part 621 and the second branch part 622 are directly butted with the fresh air exhaust port 512, and the upper ends of the first branch part 621 and the second branch part 622 extend to the two communication ports obliquely upwards towards the two sides respectively.

The fresh air at the fresh air discharge port 512 is divided into two paths, one of which flows along the first flow dividing portion 621 to the first communication port 1311 and the first through-hole 631, and the other of which flows along the second flow dividing portion 622 to the second communication port 1312 and the second through-hole 632.

Referring to fig. 2, the indoor unit of the air conditioner further includes a volute 4, the volute 4 is disposed in the casing 1, the volute 4 defines most of the heat exchange air duct 13, a portion of the front panel 11 extends from the inner side of the indoor air outlet 12 to the front end of the volute 4, the volute 4 includes a volute bottom plate 41 located below the heat exchange air duct 13, and the communication port is formed in the volute bottom plate 41, so that the communication port is conveniently disposed.

The above embodiments are only specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, and all should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
