Abstract

The invention relates to a compressor and a refrigeration system. The compressor comprises a compressor body internally provided with a compression chamber, and a buffering cavity. At least part of airflow exhausted by the compression chamber flows through the buffering cavity and then is exhausted, and accordingly the exhaust noise is lowered. Through the arrangement of the buffering cavity, pulsation of airflow exhausted by the compression chamber can be attenuated, and accordingly the exhaust noise of the compressor is lowered.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a compressor and a refrigeration system. Background technique [0002] At present, the advantages of high energy efficiency and low cost of variable frequency compressors have been widely used; the development of variable frequency screw compressors can replace the situation of parallel connection of multiple machines, so that the screw units can reach the national first-class energy efficiency standard; The number of meshes per unit time increases, the exhaust flow rate increases, and the air pulsation also increases, which increases the noise of the compressor. The noise of the frequency conversion compressor is an urgent problem to be solved. Contents of the invention [0003] The purpose of the present invention is to provide a compressor and a refrigeration system, which can solve the problem of high exhaust noise of the compressor. [0004] In order to achieve the ...
