Abstract
A liquid refrigerant from a compressor and a condenser is alternately supplied to a cooling device for the freezing room 27F and an evaporator for refrigeration room through a three-way valve, so as to conduct the cooling of a freezing room and a refrigeration room. When the thermal load condition of a refrigerating cycle is light, the three-way valve switches to the “F side opened-state” after the compressor is stopped, and thereby conducting pressure balancing, without the liquid refrigerant flowing into the evaporator for refrigeration room. 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.
