To suppress leakage of water from a ventilation device.SOLUTION: A ventilation system 10 includes a ventilation device 11, a first temperature sensor 38, a second temperature sensor 39 and a ventilation controller 36. The ventilation device 11 includes a heat exchanger 32, an air supply passage 47, an air exhaust passage 46, an air supply fan 34 and an air exhaust fan 33. The ventilation controller 36 can execute a first mode of operating 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, or 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 difference between a second detection value K2 and a first detection value K1 is a second predetermined value T2 or smaller, 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温度センサ３８と第２温度センサ３９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と給気通路４７及び排気通路４６と給気ファン３４と排気ファン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を運転させる第１モード、及び給気ファン３４を停止、間欠運転、若しくは弱運転させる第２モード、又は、排気ファン３３を停止、間欠運転、若しくは弱運転させる第３モード、を実行可能であり、第１モードの実行中、第２検出値Ｋ２と第１検出値Ｋ１との差が第２所定値Ｔ２以下である場合に、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
