REFRIGERATING DEVICE

A refrigerating apparatus includes a first refrigerant circuit including a first compressor, a first condenser, a first pressure reducer, and a first evaporator, connected circularly with a first refrigerant pipe, a refrigerant discharged from the first compressor being condensed at the first condenser and thereafter evaporated at the first evaporator to acquire a cooling effect; a second refrigerant circuit including a second compressor, a second condenser, a second pressure reducer, and a second evaporator, connected circularly with a second refrigerant pipe, a refrigerant discharged from the second compressor being condensed at the second condenser and thereafter evaporated at the second evaporator to acquire a cooling effect; a temperature sensor that detects a temperature of an internal portion of a cold storage cabinet, the first evaporator and the second evaporator being disposed to cool the internal portion at the same time; and a first control device that controls the first compressor and the second compressor in such a manner that both the first compressor and the second compressor are operated each time the detected temperature of the temperature sensor reaches a first temperature, and controls the first compressor and the second compressor in such a manner that the first compressor and the second compressor are alternately operated each time the detected temperature of the temperature sensor reaches a second temperature that is lower than the first temperature.
