A liquid refrigerant from a compressor 20 and a condenser 21 is alternately supplied to a cooling device for the freezing room 27F and an evaporator for refrigeration room 27R through a three-way valve 24, so as to conduct the cooling of a freezing room and a refrigeration room. When the thermal load condition of a refrigerating cycle 40 is light, the three-way valve 24 switches to the “F side opened-state” after the stop of the compressor 20, and thereby conducting pressure balancing, without the liquid refrigerant flowing into the evaporator for refrigeration room 27R. A cooling storage, wherein from one compressor a refrigerant is selectively supplied to multiple evaporators, is constituted so as to prevent one evaporator side from becoming a supercooled state, and furthermore, quickly conduct pressure balancing after stop of the compressor.
