An Experimental Study on the Pressure Differentials during the Pressurized Air Supply to the Elevator Lobby

부속실 급기가압제연시 차압변화에 관한 실험적 연구

A fire should be accompanied by the heat and smoke. However, smoke is considered main cause of heavy casualties. Smoke easily spreads away from the fire area to remote space and cause mortal wound for the resident. A technical way effectively protecting the life and property from the smoke is the smoke control system of the building. Pressurized air supply system can be considered to prevent the refuge area from the smoke infiltration that evacuate residents via evacuation route for life safety. This paper is related with performance estimation and the effectiveness of the pressurized air supply system through experiments.
