摘要: A refrigeration apparatus includes a high-temperature side circulation circuit, a low-temperature side circulation circuit, a cascade capacitor, and control means. The high-temperature side circulation circuit forms a refrigerant circuit in which a high-temperature side compressor, a high-temperature side condenser, a high-temperature side expansion device, and a high-temperature side evaporator are connected by a pipe. The refrigerant circuit allows a high-temperature side refrigerant to circulate therethrough. The high-temperature side refrigerant has a carbon-carbon double bond in its molecular structure. The high-temperature side compressor has a variable discharge capacity and is configured to discharge the high-temperature side refrigerant. The low-temperature side circulation circuit forms a refrigerant circuit in which a low-temperature side compressor, a low-temperature side condenser, a low-temperature side expansion device, and a low-temperature side evaporator are connected by a pipe. The refrigerant circuit allows a low-temperature side refrigerant to circulate therethrough. The low-temperature side refrigerant contains carbon dioxide.

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.
