Patent attributes
A heat load predictor predicts a change over time of a heat amount to be processed by air-conditioning equipment, an operation plan creator previously creates an operation plan of the air-conditioning equipment to reduce an evaluation index under a first restrictive condition that a total process heat load be maintained at a same level or within a range of a predetermined amount of difference and a room temperature be maintained within a predetermined comfortable temperature range, and an operation plan corrector corrects the operation plan during controlling the air-conditioning equipment based on the operation plan. If an actually measured temperature differs from a predicted temperature predicted by the operation plan creator at the time of creating the operation plan, the operation plan creator predicts a change over time of the temperature in the room, and corrects the operation plan to minimize the evaluation index under the first restrictive condition.
