Abstract
A refrigerating apparatus includes first and second refrigerant circuits including respective first and second compressors, condensers, pressure reducers, and evaporators, connected circularly with first and second refrigerant pipes, respectively, refrigerants discharged from the first and second compressors being respectively condensed at the first and second condensers and thereafter respectively evaporated at the first and second evaporators to acquire a cooling effect; a temperature sensor that detects a temperature of an internal portion of a cold storage cabinet, the first and second evaporators being disposed to cool the internal portion simultaneously; and a first control device that controls the first and second compressors such that both of them are operated each time a temperature detected by the temperature sensor reaches a first temperature, and the first and second compressors are alternately operated each time a temperature detected by the temperature sensor reaches a second temperature lower than the first temperature.
