The invention discloses a gas-liquid separated type freezing plant, which can restrain the super-cooling of high-pressure liquid refrigerant and the overheating of inlet gas refrigerant of a compressor, so as to improve refrigerating capacity and prevent oil from deterioration. The gas-liquid separated type freezing plant is a closed-loop type refrigerant circulating loop which is formed by connecting refrigerant distributing tubes L1-L5, at least one compressor 1, a condenser 2, an expansion valve (pressure reducer ) 4, a gas-liquid separator 5 and an evaporator 6 in series. The gas-liquid separated type freezing plant is provided with a gas-liquid heat exchanger 3 for enabling the liquid refrigerant flowing to the expansion valve 4 from the condenser 2 to be subjected with heat exchange with the gas refrigerant separated by the gas-liquid separator 5 and the gas refrigerant from the evaporator 6 through jetting of the liquid refrigerant so as to realize super-cooling. |
