To suppress leakage of water from a ventilation device.SOLUTION: A ventilation system 10 includes a ventilation device 11, a first humidity sensor 38 and a ventilation controller 36. The ventilation device 11 includes: a heat exchanger 32; an air supply fan 34 supplying air outside an indoor space S1 into the indoor space S1 via the heat exchanger 32; and an air exhaust fan 33 discharging air in the indoor space S1 to an outdoor space S2 via the heat exchanger 32. The ventilation controller 36 can execute a first mode of operating both of the air supply fan 34 and the air exhaust fan 33, a second mode of causing the air supply fan 34 to stop, perform an intermittent operation or perform a weak operation and a third mode of causing the air exhaust fan 33 to stop, perform an intermittent operation or perform a weak operation. During execution of the first mode, when a first detection value K1 of the first humidity sensor 38 reaches a first predetermined value H1 or greater, the ventilation controller 36 switches the first mode to the second mode or the third mode.SELECTED DRAWING: Figure 8 【課題】換気装置からの水漏れを抑制する。【解決手段】換気システム１０は、換気装置１１と、第１湿度センサ３８と、換気コントローラ３６と、を備え、換気装置１１が、熱交換器３２と、室内空間Ｓ１外の空気を熱交換器３２を経由して室内空間Ｓ１内に給気する給気ファン３４と、室内空間Ｓ１内の空気を熱交換器３２を経由して室外空間Ｓ２に排気する排気ファン３３と、を備え、換気コントローラ３６が、給気ファン３４及び排気ファン３３の双方を運転させる第１モード、給気ファン３４を停止、間欠運転、又は弱運転させる第２モード、排気ファン３３を停止、間欠運転、又は弱運転させる第３モード、を実行可能であり、第１モードの実行中、第１湿度センサ３８の第１検出値Ｋ１が第１所定値Ｈ１以上になった場合に、換気コントローラ３６が、第１モードから第２モード又は第３モードに切り替える。【選択図】図８
