Document Type and Number:
Japanese Patent JP3053896
Kind Code:
B2
Abstract:
PURPOSE:To approach a control target value for designating a temperature in a warehouse by following a heat load of a cooler by providing control target value setting means for setting the target value after next period based on previously designated control target value and temperature correction information. CONSTITUTION:Maximum and minimum temperature detecting means 8, 7 for detecting maximum and minimum values of a temperature in a warehouse by a temperature detector 3 at each period of ON/OFF, and upper and lower limit deviation calculating means 10, 9 for calculating a deviation of an upper limit target value from the maximum value and a deviation of a lower limit target value from the minimum value of the target value suitably temperature- corrected based on a designation, are provided. A temperature correcting accuracy of the target value is preset corresponding to combinations of the deviations, temperature correcting information of the combination is output by temperature correcting information setting means 11, and a control target value after next period is set by control target value setting means 6 based on the previously designated control target value and temperature correcting information.
