Problems solved by technology

If multiple compressors are not turned on alternately, the first compressor will be turned on more and more times in the three-stage refrigeration demand, which will reduce the service life of the first compressor

Embodiment Construction

[0038] In order to enable those skilled in the art to further understand the features and technical contents of the present invention, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings and implementation methods.

[0039] Embodiments of the present invention provide a refrigeration method and system. For a refrigeration system with at least two compressors, each compressor is numbered, and the number of times each compressor is turned on is recorded. When refrigeration is required, if there is a compressor with the lowest number of starts, start sequentially from the compressor with the lowest number of starts according to the number of refrigeration stages; otherwise, start from the compressor with the lowest number according to the number of refrigeration stages . Therefore, multiple compressors can be started alternately, instead of being always started according to the serial number of the compressors, ...

Abstract

The invention relates to the technical field of temperature control, in particular to a refrigerating method and system. The refrigerating method comprises the following steps: arranging at least twocompressors, numbering the compressors, and recording the starting times of each compressor; determining the refrigerating level when refrigeration is needed; sorting the compressors according to thestarting times from fewer times to more times; if the compressor with the fewest starting times, sequentially starting the compressors from the compressor with the fewest starting times according to the refrigerating level. With adoption of the refrigerating method, the service life is prolonged when a plurality of compressors are used for refrigeration.

Description

technical field [0001] The invention relates to the technical field of temperature control, in particular to a refrigeration method and system. Background technique [0002] At present, in the refrigeration control system that connects multiple compressors through a thermostat, the cooling demand is divided into multiple levels, for example, divided into three levels. When the first level of cooling demand is running, the first compressor needs to be turned on; when the second level of cooling demand The first compressor and the second compressor need to be turned on during operation, and the first compressor, the second compressor and the third compressor need to be turned on when the third-stage refrigeration demand is running. If the multiple compressors are not alternately turned on, the number of times the first compressor is turned on in the three-stage cooling demand will increase, thereby reducing the service life of the first compressor. Contents of the invention ...
