Zusammenfassung:To control ventilation of a target space on the basis of an infection risk index determined on the basis of a state of the target space.SOLUTION: A ventilation system (1) comprises: a calculation unit (45) for determining an infection risk index on the basis of at least one of indexes based on sound emitted by persons in a target space (S), density of persons in the target space (S), and an amount of air flowing in the target space (S); a ventilation device (7) for ventilating air in the target space (S); and a control unit (40) for controlling the ventilation device (7) on the basis of the infection risk index.SELECTED DRAWING: Figure 1 【課題】対象空間の状態に基づいて決定される感染リスク指標に基づいて、該対象空間の換気を制御する。【解決手段】換気システム(1)は、対象空間(S)における人が発する音、該対象空間(S)における人の密度、および該対象空間(S)に流れる空気量に基づく指標の少なくとも1つに基づいて、感染リスク指標を求める演算部(45)と、該対象空間(S)の空気を換気する換気装置(7)と、感染リスク指標に基づいて換気装置(7)を制御する制御部(40)とを備える。【選択図】図1
