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.

In addition, the flow dividing portion, the flow guiding portion 422 or/and the communicating member 41 may be integrally injection-molded or may be separately connected.
In some embodiments, the flow guide 42 may be "V" shaped, including a first flow split 4231 and a second flow split 4232. The lower ports of the first and second flow-dividing portions 4231 and 4232 are butted with the fresh air exhaust port 412, and the upper ends thereof extend obliquely upward to the communicating member 41 toward both sides.
The fresh air at the fresh air outlet 412 is divided into two paths, one path flows to the first air flow passage 4111 along the first branch portion 4231, and the other path flows to the second air flow passage 4112 along the second branch portion 4232.
Referring to fig. 9, 11, 12 and 19, the indoor air conditioner further includes a volute 23, the volute is disposed in the casing and is used for defining the heat exchange air duct 13, the volute includes a front volute tongue, a rear volute tongue and a volute top plate 231 located above the heat exchange air duct, and the communication port is formed in the volute top plate and is convenient to be disposed. Referring to fig. 13 and 14, the housing case further defines a connection passage 16 that communicates the communication port with the airflow passage. The connecting channel 16 is located above the volute top plate 231.
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.
