A refrigerating apparatus comprising: a cold storage cabinet; a first refrigerant circuit including a first compressor, a first condenser, a first pressure reducer (108, 110), 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 (208, 210), 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 configured to detect 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 configured to control the first compressor and the second compressor according to a first control mode such that both the first compressor and the second compressor are operated in first time intervals starting when the detected temperature reaches a first temperature until the detected temperature reaches a second temperature lower than the first temperature, characterized in that the first control mode is further as such that alternately either the first compressor or the second compressor are operated in second time intervals starting when the detected temperature reaches the second temperature until the detected temperature reaches the first temperature; a second control device configured to control the first compressor and the second compressor according to a second control mode such that alternately either the first compressor or the second compressor are operated in the first time intervals, and that neither the first compressor nor the second compressor are operated in the second time intervals; and a first switching device configured to switch over control from the second control device to the first control device when a temperature detected by the temperature sensor reaches a third temperature higher than the first temperature, and to switch over control from the first control device to the second control device when a temperature detected by the temperature sensor reaches a fourth temperature lower than the second temperature. a cold storage cabinet; a first refrigerant circuit including a first compressor, a first condenser, a first pressure reducer (108, 110), 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 (208, 210), 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 configured to detect 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 configured to control the first compressor and the second compressor according to a first control mode such that both the first compressor and the second compressor are operated in first time intervals starting when the detected temperature reaches a first temperature until the detected temperature reaches a second temperature lower than the first temperature, characterized in that the first control mode is further as such that alternately either the first compressor or the second compressor are operated in second time intervals starting when the detected temperature reaches the second temperature until the detected temperature reaches the first temperature; a second control device configured to control the first compressor and the second compressor according to a second control mode such that alternately either the first compressor or the second compressor are operated in the first time intervals, and that neither the first compressor nor the second compressor are operated in the second time intervals; and a first switching device configured to switch over control from the second control device to the first control device when a temperature detected by the temperature sensor reaches a third temperature higher than the first temperature, and to switch over control from the first control device to the second control device when a temperature detected by the temperature sensor reaches a fourth temperature lower than the second temperature.
