Abstract: In an operating quantity calculating portion, an operating quantity controlling an air-conditioned space to a target air-conditioning environment is calculated for each individual air-conditioning equipment through performing CFD reverse analysis on the air-conditioning environment of the air-conditioned space; in a state estimating portion, state setting values indicate the state of the target air-conditioning environment at the measurement locations of the individual sensors provided in the air-conditioned space are estimated respectively through CFD forward analysis on these operating quantities; and, in a feedback controlling portion, a coordinating factor is calculated based on the deviations between the state setting values obtained and the state measured values that are measured by the sensors, where coordinated operating quantities are calculated through correcting each of the operating quantities by the coordinating factor, and coordinated feedback control of the air-conditioning equipment is perform
