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.
