VENTILATION SYSTEM USING A NON-POWER DAMPER UNIT

摘要

A ventilation system using a powerless damper unit is provided to mount damper units automatically opened or closed by introduced atmospheric air to spaces having blocked ventilation paths, thereby carrying out ventilation of the spaces without mounting any air ventilation ducts. A ventilation system using a powerless damper unit includes an atmospheric air suction unit(110) for introducing atmospheric air into the center of a living room, and a plurality of powerless damper units(120) mounted at walls of spaces, wherein ventilation paths of the spaces are blocked and the spaces have relatively negative pressure comparing with a positive pressure area of the living room adjacent to the atmospheric air suction unit. The powerless damper units are automatically opened or closed from the positive pressure area to the negative pressure area by the introduced atmospheric air, thereby forming ventilation paths for the spaces.
