Embodiment Construction

[0037] Such as Figure 1-3 As shown, the present invention provides a compressor assembly, which includes:

[0038] The compressor housing 9 and the gas-liquid separator 3, the gas-liquid separator 3 communicates with the external air intake through the first inlet pipe 31, and communicates with the inside of the compressor housing 9 through the first outlet pipe 32;

[0039] It also includes a mixing heat exchange chamber 5, which is arranged outside the compressor housing 9 and capable of exchanging heat with the compressor housing 9, and the mixing heat exchange chamber 5 passes through the first The second inlet pipe 6 can communicate with the first inlet pipe 31 to suck fluid from the first inlet pipe 31, and can be connected with the gas-liquid separator 3 or with the first outlet pipe 1 through the second outlet pipe 1. The pipe 32 is connected to lead the fluid in the mixing heat exchange chamber 5 to the gas-liquid separator 3 or to the first outlet pipe 32 .

Abstract

The invention provides a compressor assembly, an air conditioner and a control method. The compressor assembly comprises a compressor shell (9) and a gas-liquid separator (3), wherein the gas-liquid separator (3) communicates with external inlet gas and communicates with the interior of the compressor shell (9) through a first outlet pipe (32), a hybrid heat exchange cavity (5) is arranged outsidethe compressor shell (9) and can exchange heat with the compressor shell (9), and the hybrid heat exchange cavity (5) can be communicated with a first inlet pipe (31) through a second inlet pipe (6)and can be communicated with the gas-liquid separator (3) or a first outlet pipe (32) through a second outlet pipe (1). The invention discloses a compressor assembly. The compressor is advantaged in that refrigerant before entering the gas-liquid separator enters the hybrid heat exchange cavity to be heated and then is guided into the compressor shell to be compressed, the air suction superheat degree of the compressor is effectively increased, the situation that liquid is carried in air suction of the compressor is prevented, liquid impact is prevented, and running reliability and safety of the compressor are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a compressor assembly, an air conditioner and a control method. Background technique [0002] When the rotary compressor operates at light load and low frequency, due to the small cooling / heating load, it is easy to cause incomplete evaporation of the evaporator. The refrigerant coming out of the evaporator is a gas-liquid two-phase state. When the gas-liquid mixed refrigerant enters the compression It is easy to cause liquid shock in the cylinder of the compressor, which is very harmful to the compressor: first, it will increase the power of the compressor, which is easy to cause wear and tear, which is very unfavorable to the reliability of the compressor; second, it may cause the rollers to separate from the slides, The collision between the sliding vane and the roller causes abnormal noise and the air conditioner cotton cannot be weakened, which seriously affe...
