Problems solved by technology

[0002] The current rotary compressor has insufficient energy efficiency in a low-temperature environment, and its heating capacity is greatly reduced, which cannot meet the heating needs of users.
In order to solve this problem, some twin-cylinder rotary compressors such as jet compressors have appeared, but due to their unreasonable structural design, they have caused a series of problems such as high cost, low cost performance, low energy efficiency, and poor reliability.

Description

technical field [0001] The invention relates to the technical equipment field of compressors, in particular to a rotary compressor and a refrigeration device. Background technique [0002] The current rotary compressor has insufficient energy efficiency in a low-temperature environment, and its heating capacity is greatly attenuated, which cannot meet the heating needs of users. In order to solve this problem, there have been some twin-cylinder rotary compressors such as jet compressors, but due to their unreasonable structural design, they have caused a series of problems such as high cost, low cost performance, low energy efficiency, and poor reliability. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention aims to provide a rotary compressor, which has the advantages of good low-temperature heating effect, high energy efficiency, high cost performance, a...
