Problems solved by technology

However, the multi-exhaust compressor has multiple exhaust ports with different exhaust pressures, and a single motor cannot realize all the separation and recovery of lubricating oil, so that a large amount of lubricating oil is discharged through the exhaust port, resulting in serious oil shortage in the compressor. Even burning, and it will also cause a large amount of lubricating oil to enter the heat exchanger connected with the compressor, affecting the heat transfer performance

Abstract

The invention provides a compressor assembly and refrigeration equipment. Wherein, the compressor assembly includes: a compressor, the compressor includes a housing and a first exhaust port and a second exhaust port located on the housing, the first exhaust port is used to discharge gas at a pressure lower than that of the second exhaust port The port is used for the pressure of the discharged gas; the first oil separator, the inlet of the first oil separator communicates with the first exhaust port, the liquid outlet of the first oil separator communicates with the inner cavity of the housing, and / or the second Two oil separators, the inlet of the second oil separator communicates with the second exhaust port, the liquid outlet of the second oil separator communicates with the inner cavity of the housing; wherein, the first exhaust port communicates with the inner cavity of the housing , or the second exhaust port communicates with the inner cavity of the housing. The existence of the oil separator can better realize the oil return of the compressor, avoid oil shortage in the compressor, and prevent the compressor from sending a large amount of lubricating oil to the heat exchanger connected to it, resulting in poor heat exchange effect of the heat exchanger.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a compressor assembly and a refrigeration device. Background technique [0002] Multi-exhaust compressors generally contain a large amount of lubricating oil in the compression process considering factors such as friction, heat dissipation, and sealing. At present, the lubricating oil is mainly blocked and cooled by the motor inside the compressor, so that the lubricating oil remains in the compressor, so as to prevent the lubricating oil from entering the heat exchanger in the refrigeration / heat pump system. However, the multi-exhaust compressor has multiple exhaust ports with different exhaust pressures, and a single motor cannot realize all the separation and recovery of lubricating oil, so that a large amount of lubricating oil is discharged through the exhaust port, resulting in serious oil shortage in the compressor. Even burnout, and it will also cause a l...
