Summary: | To provide a ventilation system capable of preventing an indoor space from being subjected to a negative pressure even when an exhaust device and a ventilation device are operated.SOLUTION: A ventilation system comprises a ventilation device, an exhaust device, and a controller which controls operation of the ventilation device and the exhaust device. The controller has a determination section which determines whether the exhaust device is in operation. The controller executes: a first operation mode, when the determination section determines that the exhaust device is not in operation, which includes operation to control an exhaust blower so that an exhaust air flow rate becomes a first air flow rate and operation to control an air supply blower so that an air supply flow rate becomes the first air flow rate; and a second operation mode, when the determination section determines that the exhaust device is in operation, which includes operation to control the exhaust blower so that the exhaust air flow rate becomes a second air flow rate smaller than the first air flow rate and operation to control the air supply blower so that the air supply flow rate becomes a third flow rate larger than the first air flow rate.SELECTED DRAWING: Figure 1
【課題】本開示は、排気装置と換気装置を運転した場合であっても屋内空間が負圧になることを抑制し得る換気システムを提供する。【解決手段】本開示における換気システムは、換気装置と、排気装置と、換気装置および排気装置の動作を制御するコントローラと、を備える。コントローラは、排気装置の運転が実行中であるか否かを判定する判定部を有する。コントローラは、排気装置の運転が実行中ではないと判定部が判定した場合、排気流が第一風量となるように排気送風機を運転制御する動作と給気流が第一風量となるように給気送風機を運転制御する動作とを含む第一運転モードを実行する。コントローラは、排気装置の運転が実行中であると判定部が判定した場合、排気流が第一風量より小さい第二風量となるように排気送風機を運転制御する動作と給気流が第一風量より大きい第三風量となるように給気送風機を運転制御する動作とを含む第二運転モードを実行する。【選択図】図1 |
