Description

Cylinder assembly, compressor and refrigeration equipment Technical Field The invention relates to the technical field of cylinder assemblies, in particular to a cylinder assembly, a compressor and refrigeration equipment. Background At present, a double-cylinder rotary compressor is provided with two cylinders, each cylinder is generally provided with an air inlet hole, and meanwhile, the liquid storage device is also provided with two air suction pipes which are respectively communicated with the two cylinders. In order to reduce the cost, the double-cylinder rotary compressor in the related art adopts a double-cylinder single-suction design, namely, an air inlet hole is arranged on one cylinder or a partition plate, the air inlet hole is connected with a liquid storage device, and the liquid storage device is provided with only one suction pipe. Specifically, the refrigerant entering from the air inlet hole is divided into two parts, and is communicated with one or two cylinders through the air dividing holes on the partition plate. However, the intake air amount of the cylinder is insufficient due to the reduction in the number of intake holes.
