VENTILATION SYSTEM, VENTILATION CONTROL METHOD AND PROGRAM

To provide a ventilation system properly ventilating an indoor space in accordance with air flow.SOLUTION: A ventilation system includes: a first ventilation device 10 and a second ventilation device 11 (a plurality of ventilation devices) arranged at different positions and performing ventilation of an indoor space 5; an air-quality sensor 20 measuring the degree of pollution of air in the indoor space 5; air quantity control means 33 determining a ventilation volume due to the first ventilation device 10 and the second ventilation device 11 on the basis of a detection value obtained by the air-quality sensor 20; and air quantity setting means 34 setting the air quantity of the first ventilation device 10 and the second ventilation device 11 on the basis of the ventilation volume determined by the air quantity control means 33. The air quantity control means 33 acquires an influence quantity of the first ventilation device 10 and the second ventilation device 11 from an amount of change in the detection value by the air-quality sensor 20 when operating the ventilation device at a prescribed air quantity by the air quantity setting means 34, and the air quantity control means 33 determines the air quantity on the basis of the influence quantity.SELECTED DRAWING: Figure 4 【課題】本開示は、空気の流れに応じて室内空間の換気を適正に行うことができる換気システムを提供する。【解決手段】異なる位置に配置された室内空間５の換気を行う第１の換気装置１０および第２の換気装置１１（複数の換気装置）と、室内空間５の空気の汚染度を計測する空質センサ２０と、空質センサ２０の検出値に基づいて第１の換気装置１０および第２の換気装置１１による換気量を決定する風量制御手段３３と、風量制御手段３３により決定された換気量に基づいて第１の換気装置１０および第２の換気装置１１の風量を設定する風量設定手段３４と、を備える。風量制御手段３３は、風量設定手段３４により換気装置を所定の風量で動作させた時の空質センサ２０の検出値の変化量から第１の換気装置１０および第２の換気装置１１の影響量を求め、風量制御手段３３は、影響量に基づいて風量を決定する。【選択図】図４
