Title:
REFRIGERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/036115
Kind Code:
A1
Abstract:
A refrigeration system (100) comprises: a multi-level compressor (10) comprising at least two levels of compression portions in sequential communication; a first refrigeration device having a first gas inlet end and a first gas discharge end, the first gas discharge end communicating with the compression portions at any two levels, the first gas inlet end communicating with a gas discharge opening of the higher-level compression portion of the compression portions at any two levels or communicating with a gas discharge opening of a compression portion at a level higher than the higher level compression portion; a second refrigeration device having a second gas inlet end and a second gas discharge end, the second gas inlet end communicating with a gas discharge opening of the compression portion at the highest level, and the second gas discharge end communicating with a gas return opening of the compression portion at the lowest level; and a bypass mechanism (40) provided between the first gas discharge end and the gas return opening of the compression portion at the lowest level, wherein when the first refrigeration device is operating and the second refrigeration device stops operating, the bypass mechanism (40) is turned on, and the compression portion at a lower level in the multi-level compressor is idling, such that a load provided by the compressor matches a load required by the first refrigeration device, thereby reducing inefficient use of resources.
