摘要： 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.

摘要： The liquid refrigerant from the compressor 20 and the condenser 21 is alternately supplied to the cooling device for the freezing room 27F and the evaporator for the refrigeration room 27R through the three-way valve 24, so that the freezing room and the refrigeration room are alternately cooled. Here, the ratio of the refrigerant supply time to each evaporator is controlled based not on a deviation between a target temperature set for each storage room and an actual storage room temperature measured in each storage room, but on an integrated value obtained by integrating the difference of these deviations. In a cooling storage, in which from one compressor a refrigerant is selectively supplied to multiple evaporators respectively disposed in multiple storage rooms of varied thermal loads, a one-storage room cooling mode is prevented from being unnecessarily switched to a alternate cooling mode.

摘要： PROBLEM TO BE SOLVED: To provide a cooling storage, in which a refrigerant from one compressor is selectively supplied to multiple evaporators respectively disposed in multiple storage rooms having different thermal loads, and prevent any temperature rise of a storage room of higher thermal load.SOLUTION: The liquid refrigerant from the compressor 20 and the condenser 21 is alternately supplied to the cooling device for the freezing room 27F and the evaporator for the refrigeration room 27R through the three-way valve 24, so that the freezing room and the refrigeration room are alternately cooled. Even if any one of the freezing room 13F and the refrigeration room 13R reached the lower limit set temperature on ahead, the freezing room 13F (the storage room of higher thermal load) is always cooled last and certainly cooled until it reaches the lower limit set temperature.

摘要： Deviation calculating means 42 calculates a deviation between an internal temperature detected by a temperature sensor 35 and a target temperature provided from target temperature setting means 41 for each predetermined time period. The deviation is integrated by deviation integrating means 46. When the integrated value exceeds a predetermined reference value, a rotational speed of an inverter motor that drives a compressor is increased. Therefore, for example, even if an internal temperature temporarily rises because a door is opened temporarily and outside air flows into a storage compartment, because there is no sudden change in the integrated value of the temperature deviation and the rotational speed of the compressor does not react in an oversensitive manner and rapidly increase. Consequently the control is stable. Thus, an unnecessarily oversensitive response to a sudden change in an internal temperature can be prevented, enabling operation at a higher efficiency.
