Problems solved by technology

However, in the case where an independent refrigeration system uses a compressor and a condenser to provide refrigeration to only one chamber of the refrigerator, in order to meet the maximum energy demand for refrigeration during design, it is usually necessary to equip a refrigerator with a large

Abstract

The invention relates to a refrigerating system for refrigerator. It includes compressor, condenser, and evaporator. The compressor is two parallel one between each of which and the evaporator one way valve is connected. While the refrigerating system needs high load refrigerating, or the refrigerator is used with high frequency, the two compressors can be used together to supply required refrigerating capacity. And the one way valve can make the compressed gas pass the condenser to realize refrigerating effect, but not directly flow to the evaporator. On the contrary, any one of the compressors can realize required refrigerating load. Thus the invention can greatly improve the refrigerating efficiency, effectively save the energy sources.

Description

technical field [0001] The invention relates to a refrigerator refrigeration system, in particular to a refrigerator refrigeration system in which two compressors are connected in parallel in a refrigeration circuit. Background technique [0002] The domestic refrigerators sold on the market today basically adopt an independent refrigeration system, or use an independent refrigeration system to expand into a double-cycle or multi-cycle refrigeration system through mechanical valves or solenoid valves (for example: mechanically controlled refrigerated freezer, dual-temperature dual-control refrigerator, three-temperature four-control refrigerator, three-cycle refrigerator, four-cycle refrigerator, frost-free refrigerator-freezer, and mixed refrigeration refrigerator, etc.), and these refrigerators are all through A compressor and a condenser etc. complete the cooling work. [0003] In addition, there are also some domestic refrigerators that use an independent refrigeration ...
