Rotary compressor, air conditioning system, and control method

Abstract

A rotary compressor, an air conditioning system, and a control method. The rotary compressor includes a compressor body and a pipeline. The compressor body includes an upper cylinder cover, a lower cylinder cover, and a cylinder. The upper cylinder cover and/or the lower cylinder cover is provided with a pressure relief channel in communication with a compression chamber of the cylinder; a first end of the pipeline is connected to the pressure relief channel, and a second end of the pipeline is in communication with a suction chamber of the cylinder or a device in communication with the suction chamber. A first valve is configured to block or conduct the pipeline. The pressure difference between a high-pressure side and a low-pressure side of the compressor can be balanced more quickly, thus shortening the time required to restart the rotary compressor after shutdown.
