    摘要: A cooling storage cabinet includes a freezing compartment, a refrigerating compartment, a compressor, a three-way valve, and a control circuit. The control circuit is configured such that: when an internal temperature of the freezing compartment becomes lower than a lower limit temperature during R-compartment F-compartment alternate cooling, starting R-individual overcool preventing control is requested, the rotational speed of the compressor is decreased by one stage and, subsequently, the three-way valve enters “R-side open state”, and individual cooling of the refrigerating compartment is executed; thereafter, every 30 seconds, the rotational speed of the compressor is decreased by one stage; when the refrigerating compartment temperature becomes lower than a lower limit temperature, stopping R-individual overcool preventing control is requested; and then, the process shifts to individual cooling of the freezing compartment, and after the freezing compartment again becomes lower than the lower limit temperature, the compressor is stopped.

    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: A deviation calculating unit 42 calculates a deviation between an internal temperature detected by a temperature sensor 35 and a target temperature provided from a target temperature setting unit 41 for each predetermined time period. The deviation is integrated by a deviation integrating unit 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.
