A refrigerator where a variable- performance freezing cycle that has coolers for freezing and cold storage and is formed as a two-stage compression-type is controlled by freezing space temperature information, so that a freezing space and a cold storage space are each appropriately controlled at its storage temperature. A refrigerator where a freezing cycle is formed by an inverter-driven variable-performance compressor (9) where a compression element is constituted of a low stage side compression section (9a) and a high stage side compression section (9b), by a switching valve (11) for controlling a flow rate together with a refrigerant flow path provided on the exit side of a condenser (10) receiving a discharge gas from the compressor, and by cooler (4) for freezing and a cooler (5) for cold storage that are respectively connected through pressure reducing devices (12, 13) to the switching valve, wherein the rotating speed of the compressor is determined by a freezing space temperature (Fa) and a target value (Fr) for the freezing space temperature.
