Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0032] see figure 1 and figure 2 As shown, according to an embodiment of the present invention, a compressor structure is provided, and the compressor structure may be a centrifugal compressor, a screw compressor, or the like. A compressor with an air supply pipe includes an air suction pipe 11, an exhaust pipe 12 and an air supply pipe 13. The first end of the air supply pipe 13 communicates with the exhaust pipe 12, and the second end of the air supply pipe 13 communicates with the suction pipe 11. The air pipe 13 is provided with a regulating valve 14 .

[0033] The refrigerant compressed by the compressor enters the exhaust pipe and is divided into two paths, one path is output from the outlet of the exhaust pipe to the condenser, and the other path flows into the suction pipe t...

Abstract

The invention discloses a compressor with a blowdown pipe, an air conditioning unit and a control method of the compressor. The compressor comprises an air suction pipe and an exhaust pipe, the compressor further comprises the blowdown pipe, the first end of the blowdown pipe communicates with the exhaust pipe, the second end of the blowdown pipe communicates with the air suction pipe, and an adjusting valve is arranged on the blowdown pipe. According to the compressor with the blowdown pipe, the air conditioning unit and the control method of the compressor, the problems that the performance of the compressor is reduced and the performance of the air conditioning unit is low due to the structural arrangement of the compressor in the prior art can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to a compressor with an air supply pipe, an air-conditioning unit and a control method for the compressor. Background technique [0002] The refrigeration system of a common air-conditioning unit is composed of an evaporator, a compressor, a condenser and an expansion mechanism. The components are connected by pipes. The pipe connecting the evaporator and the compressor is the suction pipe, and the pipe connecting the condenser and the compressor for the exhaust pipe. [0003] In the prior art, the suction temperature of the suction pipe is low, and there may be the following problems: 1) Condensation occurs in the suction pipe, so that the refrigerant entering the compressor contains liquid droplets, which leads to deterioration of the flow in the compressor, rotation and detachment, Surge and other phenomena lead to a decrease in compressor performance; 2) The ...
