DEMAND CONTROL DEVICE AND COMPUTER READABLE MEDIUM

摘要

There is provided air-conditioning control in a low power operation so as not to exceed a target demand power amount in a predetermined measurement period while preventing deterioration of comfortableness of a living space. There include a reducible-power-amount estimation unit configured to calculate, for each group, a reducible power amount by making indoor units perform, for each group, a shut-off operation for a minimum shut-off time in the first half of a demand time limit, and a reduced-power-amount determination unit configured to distribute, when a power consumption amount predicted by a power consumption amount prediction unit exceeds a target demand power amount after the first half of the demand time limit passes, the exceeding power amount to each zone, evenly distribute, in each zone, the distributed power amount to each group, and calculate, based on the reducible power amount of each group, a shut-off time of each group when each group performs the shut-off operation to reduce the distributed power amount.

1. A demand control device comprising:
air-conditioning control means to perform low power operation control to make a group to which one or more indoor units belong perform a low power operation on a per-group basis; estimation means to estimate, as reducible power of the group, power calculated from a power amount reduced when each group separately performs the low power operation for a predetermined measurement unit time in a predetermined measurement period from a start point of a demand time limit; prediction means to predict a power consumption amount of the demand time limit; and calculation means to calculate, when the power consumption amount predicted by the prediction means exceeds a target demand power amount previously set to the demand time limit, a power amount to be reduced in order not to exceed the target demand power amount as a target reduced power amount, distribute the target reduced power amount to each group according to previously set distribution criteria, and calculate, for each group, a low power operation time to reduce the target reduced power amount distributed for each group based on the reducible power, wherein the air-conditioning control means makes the group perform the low power operation for the low power operation time calculated for each group by the calculation means.
