摘要:
An operation plan correction unit is included which, after start of operation based on an operation plan, predicts a subsequent hot water supply load at a predetermined day on the basis of a hot water supply load result at the predetermined day, and changes a subsequent operation plan at the predetermined day generated by an operation plan generation unit, on the basis of the hot water supply load predicted again and a remaining amount of stored hot water in a hot water storage tank.

An air-conditioning system control device (41) controls one or a plurality of air-conditioning apparatus (21) installed in a building, and includes an air-conditioning apparatus data obtaining unit (64), a heat load estimation obtaining unit (62), and air-conditioning apparatus control command determining unit (63) that determines an air-conditioning apparatus control command so that a preset evaluation index satisfies a preset condition in a preset control-target period under a preset constraint. The air-conditioning apparatus control command determining unit (63) includes time sections to divide the control-target period by one or a plurality of preset division intervals, determines a room-temperature change permissible range within which a room temperature satisfies the constraint, determines a heat-load change permissible range, based on the room temperature, the room-temperature change permissible range, a heat load estimation (53), and a heat load to be processed by each of the air-conditioning apparatus (21), and determines, for each of the time sections, as the air-conditioning apparatus control command, an operation frequency and start-stop of the air-conditioning apparatus (21), based on the heat-load change permissible range and an operation efficiency of the air-conditioning apparatus (21).
摘要:
There are provided a heat load prediction unit (32) that predicts a change over time of a heat amount to be processed by air-conditioning equipment (12), an operation plan creation unit (33) that previously creates an operation plan of the air-conditioning equipment (12) to reduce an evaluation index under a first restrictive condition that a total process heat load be maintained at the same level or within the range of a predetermined amount of difference and that the temperature in a room be maintained within a predetermined comfortable temperature range, and an operation plan correction unit (34) that corrects the operation plan during execution of control of the air-conditioning equipment (12) in accordance with the operation plan. If an actually measured temperature measured by a temperature sensor is different from a predicted temperature predicted by the operation plan creation unit (33) at the time of creation of the operation plan, the operation plan correction unit (34) 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, with a second restrictive condition set as that an error between a predicted temperature predicted by the operation plan correction unit (34) and the predicted temperature predicted by the operation plan creation unit (33) be maintained within a predetermined allowable fluctuation range at one time or a plurality of times in the correction application period.
