Document Type and Number:
Japanese Patent JP6830005
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a knockdown prefabricated cooling storage that includes a cooling device and an additional function unit having additional function other than the cooling, and controls the whole system concerning this efficiently.SOLUTION: A prefabricated refrigerator includes a cooling device for cooling the inside of a storage, and an air pressure valve heater (example of an additional function unit) installed in an air pressure regulation device and electrically controlled. An operation control unit controls the energization to the air pressure valve heater in association with the cooling device. The operation control unit permits or cuts off the energization to the air pressure valve heater in association with power on/off operation of the cooling device, and also compares a preset air pressure valve heater ON-temperature (first air pressure valve heater control temperature) Tor an air pressure valve heater OFF-temperature (second air pressure valve heater control temperature) Twith an internal temperature Tserving as a guide of the operation control of the cooling device, outputs a command signal based on results of comparison, and thereby controls the energization to the air pressure valve heater.SELECTED DRAWING: Figure 7
