PROBLEM TO BE SOLVED: To provide a cooling target control system and a cooling target control program restricting electrical power demand more easily.SOLUTION: A cooling target control system 1 comprises a plurality of cases 1101 to 1121, 1201 to 1217, 1301, 1401 to 1403, 1501 and 1502 cooled by freezers 11 to 15, and a control part 22 for controlling a working timing of defrosting operation at the plurality of cases so as to make a variation in consumption power per unit time minimum under application of an index value obtained by dividing a multiplied value of a rated load of each of the cases and a rated output of a freezer with a rated consumption power of the freezer.SELECTED DRAWING: Figure 1 |
