Compressor assembly, control method and air conditioner

Abstract

The invention provides a compressor assembly, a control method and an air conditioner. The compressor assembly comprises a first compressor and a first oil separator, and further comprises a first pipeline, a second pipeline, a third pipeline and a first oil return pipeline. One end of the first pipeline communicates with the exhaust end of the first compressor, and the other end of the first pipeline communicates with a suction inlet of the first oil separator. A discharge outlet of the first oil separator communicates with an oil return opening of the first compressor through the first oil return pipeline. One end of the third pipeline communicates with an oil outlet of the first oil separator, and the other end of the third pipeline can communicate with an exhaust pipeline. One end of the second pipeline communicates with the first pipeline, and the other end of the second pipeline communicates with the third pipeline. According to the compressor assembly, the control method and theair conditioner, the oil return problem of the compressor can be effectively solved, oil return of the compressor is good, and automatic oil return of the compressor is achieved.

Description

technical field [0001] The present disclosure relates to the technical field of air conditioners, in particular to a compressor assembly, a control method and an air conditioner. Background technique [0002] Patent No. 201320652835.6 discloses a two-stage refrigeration compressor unit device that avoids oil leakage, but the operating conditions of this compressor are single, resulting in single use conditions, and different environments need to be redeveloped, and cannot Coping with complex working conditions. Under low temperature conditions, the compressor will have the problem of difficult oil return to the compressor, because the oil is easy to stick to the two devices and other components at low temperature; whether it is a single compressor or a two-stage compressor, there will be oil leakage and failure The phenomenon of recycling. [0003] Because the compressor in the prior art has the problem of difficult oil return, and the compressor also has the problem of su...
