REFRIGERATING DEVICE

A refrigerating device is provided which can improve COP when a required load is 50% of a maximum load or below. When the load required of a common evaporator is 50% or less, a control unit stops a second compressor and controls the volume of a first compressor. Accordingly, it becomes possible to i...

Zusammenfassung:	A refrigerating device is provided which can improve COP when a required load is 50% of a maximum load or below. When the load required of a common evaporator is 50% or less, a control unit stops a second compressor and controls the volume of a first compressor. Accordingly, it becomes possible to improve COP when the required load is equal to or below 50% as compared to the case of controlling the first and second compressors simultaneously to a low volume.
