PURPOSE:To allow a refrigerator to be independently operated regardless of the actuation of a switch for cooling by configurating a device in such a way that the device is provided with such items as a medium circuit for cooling having an evaporator, a control valve which controls the medium flow to the medium circuit, and a means of controlling the closing operation of the said valve, and the medium flow to the evaporator is suspended when the refrigerator is separately operated. CONSTITUTION:Refrigeration medium circuits 8 and 80 for cooling are arranged in parallel with a refrigeration medium circuit 16 for refrigeration. When both refrigerating and cooling are being operated simultaneously, the intermittent make and break action of solenoids 7 and 70 allows the medium to flow into evaporators 5 and 50 for cooling and into an evaporator 18 for refrigerating one after the other permitting the function of both cooling and refrigerating to be available simultaneously. On the other hand, when the refrigerating is being separately operated, the suspension of the medium flow to the evaporators 5 and 50 with the solenoids 7 and 70 closed and with the operation of a compressor intermitted, allows the refrigeration to be accomplished while the capacity of the compressor is set so as to correspond to the cooling capacity of a refrigerator. |
