| 摘要 |
The present invention relates to a refrigerating cycle of a refrigerator, which comprises a compressor for compressing the gaseous refrigerant evaporated by an evaporator to a high pressure at a high temperature, a condenser for condensing the gaseous refrigerant of high temperature and high pressure into liquid refrigerant, a receiver tank for temporarily storing the liquid refrigerant of high temperature and high pressure condensed by the condenser, and an expansion valve for rapidly expanding the liquid refrigerant of high temperature and high pressure supplied from the receiver tank into a mist, the misty refrigerant rapidly expanded by the expansion valve being evaporated by the evaporator to absorb the heat of an external heat exchange medium through heat exchange, wherein a pressure booster pump is provided between the outlet line of the receiver tank and the inlet line of the expansion valve to boost the pressure of the liquid refrigerant supplied from the receiver tank to the expansion valve. |
