Abrégé
Provided is a ventilation system for appropriately ventilating a given space. A ventilation system (100) is provided with carbon dioxide concentration sensors (21-23) for detecting the carbon dioxide concentration in a room, an air supply fan (13) for supplying air to the room, an exhaust fan (14) for exhausting air from the room, and a control device (18) for controlling the air supply fan (13) and/or the exhaust fan (14) on the basis of variations in detection values of the carbon dioxide concentration sensors (21-23).Classes IPC ?
