REFRIGERATION SYSTEM AND REFRIGERATED STORAGE

WIPO Patent Application WO/2021/057137

A1

The present disclosure provides a refrigeration system and a refrigerated storage comprising same, relating to the technical field of refrigeration devices, and solving the technical problems of a high compressor pressure ratio, a reduced refrigeration coefficient, and a high exhaust temperature in a refrigerated storage. The refrigeration system comprises at least two refrigerant compressing devices, a refrigerant evaporating device and a flow path switching valve set, the refrigerant compressing devices both being connected to the flow path switching valve set, and the flow path switching valve set being configured to control the refrigerant compressing devices by means of switching of the flow path switching valve set to supply a refrigerant to a refrigerant demand unit in an alternative manner or in series. The technical solution provided in the present disclosure achieves double-temperature high-efficiency refrigeration and improves the energy efficiency of the refrigeration system.
