급기가압 제연 시 전실 내 압력변화에 관한 연구

Pressurization is a method of ensuring that protected escape routes(staircases and lobbies) are kept free of smoke for shelterers and fire fighters by raising the air pressure in these spaces above that in the main part of the building. In this study, to estimate a pressurization, the characteristics of pressure difference in a room, a lobby, an air supply shaft at several building elements are investigated with a window, the (a fire) door and a air supply damper so that information about the importance of these experimental parameters can be obtained.
