    摘要： A refrigerator provided with a refrigerant circuit in which a compressor, a condenser, a liquid container, a supercooling heat exchange portion, a throttle valve, and an evaporator connected in this order by piping, a return circuit that branches from a downstream position in a refrigerant flowing direction of the supercooling heat exchange portion in the refrigerant circuit and leads to an intermediate-pressure chamber of the compressor via the supercooling heat exchange portion, a supercooling throttle valve with a variable valve opening-degree that is disposed on a refrigerant inlet side of the supercooling heat exchange portion in the return circuit, and operation state detecting means that detects operation state data in the refrigerant circuit, in which dryness-degree calculating means that calculates a dryness-degree of the refrigerant on the outlet side of the supercooling heat exchange portion in the return circuit on the basis of the detected operation state data and supercooling throttle valve control means that controls the valve opening-degree of the supercooling throttle valve so that the calculated dryness-degree gets close to the value of 1.

    摘要： A refrigeration apparatus includes a high-temperature side circulation circuit and a low-temperature side circulation circuit. The high-temperature side circulation circuit A is configured by connecting a high-temperature side compressor, a high-temperature side condenser, a high-temperature side expansion valve, and a high-temperature side evaporator of a cascade heat exchanger to one another. The low-temperature side circulation circuit is configured by connecting a low-temperature side compressor, a low-temperature side condenser of the cascade heat exchanger, a receiver that stores a liquid refrigerant, a solenoid valve, a low-temperature side expansion valve, and a low-temperature side evaporator to one another. A refrigerant in the low-temperature side circulation circuit includes a zeotropic refrigerant mixture containing at least CO2 and R32. The content of R32 in the entire zeotropic refrigerant mixture is 50% to 74% by mass, and the GWP of the zeotropic refrigerant mixture is equal to or less than 500.
