Abstract:
A refrigeration system for a refrigerating and freezing device, the refrigeration system comprising: a refrigeration assembly, which is provided with a compressor and a plurality of evaporators that form a refrigeration circuit; and an attachment assembly, which is connected to the refrigeration circuit, and is provided with a plurality of evaporation switching valves corresponding to the evaporators on a one-to-one basis, and a plurality of evaporation bypass pipelines corresponding to the evaporators on a one-to-one basis. Each evaporation switching valve is provided with a valve port for communicating with a corresponding evaporator, and a valve port for communicating with a corresponding evaporation bypass pipeline; and each evaporation switching valve is configured to adjust, by means of adjusting the opening/closing state of each valve port thereof, the flow path of a refrigerant flowing through the evaporation switching valve, so as to adjust the operation state of a corresponding evaporator.
