Compressor and heat exchange system comprising same

Abstract

The invention discloses a compressor and a heat exchange system comprising the same. The compressor comprises a shell, a liquid reservoir, a compressing mechanism, a medium-pressure air sucking pipe and a driving mechanism, wherein the shell is provided with a vent; the liquid reservoir is arranged outside the shell; the compressing mechanism is arranged inside the shell and comprises a rotary compressing structure and a reciprocating compressing structure; the rotary compressing structure is communicated with the liquid reservoir; the medium-pressure air sucking pipe is arranged outside the shell and is communicated with the reciprocating compressing structure; the driving mechanism is arranged inside the shell and is in transmission connection with the rotary compressing structure and the reciprocating compressing structure respectively. The compressor disclosed by the invention is good in heating effect at low temperature, high in running efficiency, also simple in structure, low in production cost and high in performance-to-cost ratio.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor and a heat exchange system with the compressor. Background technique [0002] In the compressor in the related art, when heating at low temperature, due to the low density of the refrigerant at the suction port, the suction amount of the refrigerant is reduced, resulting in poor low temperature heating effect and low operating efficiency of the compressor, which in turn affects heat transfer. Heat transfer performance of a system such as an air conditioning system. For this reason, some heat exchange systems use a double-cylinder rotary compressor to improve the circulation effect of the refrigerant, but the structure of the double-cylinder rotary compressor is complicated, the cost is high, and the cost performance is low. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. ...
