| 摘要 |
The present invention relates to a refrigeration system using a liquid centrifugal pump, the refrigeration system comprising a compressor, a condenser, a liquid receiver, an expansion valve, and an evaporator. The refrigeration system comprises a liquid centrifugal pump installed between the liquid receiver and the expansion valve. An inlet of the liquid centrifugal pump is connected to an outlet line of the liquid receiver; an outlet of the liquid centrifugal pump is connected to an inlet line of the expansion valve; and the inlet line of the expansion valve and a refrigerant discharge side of the compressor are connected to a bypass line for supplying a part of a liquid refrigerant discharged from the liquid receiver to the refrigerant discharge side of the compressor. |
