CONTROL SYSTEM, CONTROLLER AND CONTROL PROGRAM

To improve technology for controlling ventilation facilities.SOLUTION: An environmental control system 1 comprises: a ventilation facility controller 11 which controls windows 5 as ventilation facilities for replacing indoor air with outdoor air; and an air-conditioning facility controller 12 which controls an air-conditioning facility 6 for adjusting the indoor air. The ventilation facility controller 11 comprises: an opening/closing control part which controls opening and closing of the ventilation facilities; and a control information notification part which notifies the air-conditioning facility controller 12 of control information for letting the air-conditioning facility controller 12 control the air-conditioning facility 6 according to an opening/closing state of the ventilation facilities. The air-conditioning facility controller 12 comprises: a control information acquisition part which acquires control information from the ventilation facility controller 11; and an air-conditioning facility control part which controls the air-conditioning facility 6 based upon the control information acquired by the control information acquisition part.SELECTED DRAWING: Figure 1 【課題】換気設備を制御する技術を向上させる。【解決手段】環境制御システム１は、屋内の空気と屋外の空気とを換気するための換気設備である窓５を制御する換気設備制御装置１１と、屋内の空気を調整するための空調設備６を制御する空調設備制御装置１２と、を備える。換気設備制御装置１１は、換気設備の開閉を制御する開閉制御部と、換気設備の開閉状態に応じて、空調設備制御装置１２が空調設備６を制御するための制御情報を空調設備制御装置１２に通知する制御情報通知部と、を備える。空調設備制御装置１２は、換気設備制御装置１１から制御情報を取得する制御情報取得部と、制御情報取得部により取得された制御情報に基づいて空調設備６を制御する空調設備制御部と、を備える。【選択図】図１
