PROBLEM TO BE SOLVED: To provide a refrigerator-freezer capable of reducing electric power consumption. SOLUTION: The refrigerator-freezer is provided with a refrigerating compartment 2 for refrigerating and preserving stored objects; a freezing compartment 4 for freezing and preserving stored objects; a first compressor 11 for operating a first refrigerating cycle 10 in which a first refrigerant is made to flow; a first radiator 12 arranged in a high temperature part of the first refrigerating cycle 10; a first evaporator 14 arranged in a low temperature part of the first refrigerating cycle 10; a second compressor 21 for operating a second refrigerating cycle 20 in which a second refrigerant is made to flow; a second evaporator 24 arranged in a low temperature part of the second refrigerating cycle 20; and an intermediate heat exchanger 31 for performing heat exchange between the low temperature part of the first refrigerating cycle 10 and a high temperature part of the second refrigerating cycle 20. The refrigerating compartment 2 is cooled by the first evaporator 14, and the freezing compartment 4 is cooled by the second evaporator 24. COPYRIGHT: (C)2010,JPO&INPIT
