A compressor assembly

Abstract

The invention provides a compressor assembly. The compressor assembly comprises a compressor shell (1) and a liquid storage tank (2). The compressor shell (1) is of a revolving body structure. An exhaust opening of the liquid storage tank (2) is connected to a sucking opening of the compressor shell (1). The surface of one side of the liquid storage tank (2) is attached to the outer surface of the compressor shell (1) and covers at least part of the peripheral outer surface of the compressor shell (1) of the revolving body structure. Through the compressor assembly, low-temperature refrigerant in the liquid storage tank can be effectively used for carrying out heat absorbing and cooling on the compressor shell and the inside of a compressor, so that the exhaust temperature of the compressor is effectively lowered. The refrigerant in the liquid storage tank can be heated through the high-temperature heat of the compressor shell to reach an overheated state, liquid impact is prevented, meanwhile, the pressure ratio of the whole compressor is lowered, and the operation energy efficiency of the compressor assembly is improved. Due to isolation of the liquid storage tank, outward transmission of motor noise during operation is reduced, the noise is lowered, and the operation quality of the whole compressor is improved.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a compressor assembly. Background technique [0002] The rolling rotor compressors in the prior art are equipped with compressor liquid storage tanks in order to prevent liquid shock, so that the refrigerant entering the compressor chamber is all gas. In this solution, the compressor liquid storage tanks and shells are manufactured separately and then assembled 1. The liquid storage tank is often arranged outside the shell wall of the compressor shell, so that the center of gravity of the whole machine is not at the axial position of the compressor when the compressor assembly is assembled, which will cause the compressor to generate relatively large noise during operation; and the compressor The high-temperature heat of the compression chamber can only be taken away by the flowing air on the outer surface of the casing to cool down.

Problems solved by technology

[0002] The rolling rotor compressors in the prior art are equipped with compressor liquid storage tanks in order to prevent liquid shock, so that the refrigerant entering the compressor chamber is all gas. In this solution, the compressor liquid storage tanks and shells are manufactured separately and then assembled 1. The liquid storage tank is often arranged outside the shell wall of the compressor shell, so that the center of gravity of the whole machine is not at the axial position of the compressor when the compressor assembly is assembled, which will cause the compressor to generate relatively large noise during operation; and the compressor The high-temperature heat of the compression chamber can only be taken away by the flowing air on the outer surface of the casing to cool down. Under high-temperature conditions, due to the increase in the workload, the discharge temperature of the compressor will increase, and the pressure ratio of the whole machine will increase, making the compressor unreliable. running or shutting down

[0003] Because the compressors in the prior art have technical problems such as high exhaust temperature, high pressure ratio of the whole machine and high noise, a new compressor assembly is designed in the present invention.
