BUILDING VENTILATION SYSTEM USING VERTICAL MOVEMENTS OF ELEVATOR

摘要

The present invention relates to a building ventilation system using a vertical movement of an elevator and, more specifically, to a building ventilation system daylighting and ventilating in a building by having a shaft for daylighting and ventilating indoor on each floor and an elevator shaft lifting the elevator. The building ventilation system comprises: a communicating unit for circulating air by connecting the shaft and the elevator shaft; a discharging means which is provided between the bottom of the elevator shaft and an elevator and discharges air under the elevator to the outside by moving the air to the shaft through the communicating means by pressuring the air downward when the elevator is moved downward; and an introducing means for introducing outdoor air to the elevator shaft when the elevator is moved upward. According to the present invention, the building ventilation system easily discharges indoor air on each floor by discharging air in the elevator shaft to the shaft when the elevator is moved downward. Therefore, the building ventilation system can increase the ventilation rate of a building, provide a clean environment, and reduce costs because a primarily installed elevator is used without a separate device installed in order to discharge indoor air to the shaft.;COPYRIGHT KIPO 2014
