Abstract

The invention provides a cylinder base assembly of a piston type compressor, the piston type compressor and a refrigeration system. The cylinder base assembly comprises a cylinder body and a variablevolume switching mechanism, wherein a compression cavity and an exhaust passage are arranged on the cylinder body; the variable volume switching mechanism is arranged on the cylinder body, and the variable volume switching mechanism enables the exhaust passage to be connected with or disconnected from the compression cavity. By the adoption of the technical scheme, the problem that a single-cylinder piston type compressor in the prior art cannot change the volume can be solved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a cylinder block assembly of a piston compressor, a piston compressor and a refrigeration system. Background technique [0002] In the prior art, refrigerator compressors are divided into fixed-frequency compressors and variable-frequency compressors according to their rotational speeds, and the fixed-frequency compressors run at a fixed rotational speed, usually 50 Hz. Refrigerator compressors are often designed for a fixed working condition, and their operating capacity (volume cooling capacity) is also fixed. It is impossible to adjust the cooling capacity and power under different working conditions like the inverter compressor to meet the optimal conditions of different working conditions. Therefore, when it is matched with a refrigerator, there will be problems such as slow cooling speed of each room under high ambient temperature and uneven temperature between rooms. ...
