PROBLEM TO BE SOLVED: To provide a refrigerator including a two-stage compression compressor capable of efficiently cooling both a cooling chamber and a freezing chamber. SOLUTION: The high pressure-side discharge port of the two-stage compression compressor 12 is connected to a condenser 14, and the condenser 14 is connected to a three-way valve 15. A first outlet of the three-way valve 15 is connected to a middle pressure-side suction port of the compressor 12 through an R-capillary tube 16 and an R-evaporator 18, and further connected to an F-evaporator 26 through an F-capillary tube 24. The F-evaporator is connected to a low pressure-side suction port of the compressor 12 through a low-pressure suction pipe 28. The three-way valve 15 is switchable to a simultaneous cooling mode and a freezing mode. When the internal temperature of the cooling chamber 2 drops to a predetermined temperature during the simultaneous cooling mode, the three-way valve is switched to the freezing mode.
