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.

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 blade included in an impeller is formed so that, when viewed in a vertical cross-sectional view of the blade, a pressure surface of the blade and a suction surface of the blade opposite to the pressure surface are curved more in the direction in which the impeller rotates, in their areas farther from the axis of rotation of the impeller and closer to the exterior of the blade, and are arched so that a portion near the center of the blade is most distant from a straight line connecting the inner end and the outer end of the blade, the pressure surface and the suction surface form a curved surface including at least one circular arc, and a straight portion of the blade is formed to be connected to the curved surface on its one side, and extend toward the inner end of the blade on its other side.
