Influences of Smoke Exhaust Effect by Setting Atria Buffer Zone in Straight Corridor of Building
In high-rise building fires, a great deal of fresh air will be sent into the fire floor when pressurization is taken. Smoke is diluted by the fresh air, and the efficiency of mechanical smoke exhaust is reduced. The assumption that set atria buffer zone in straight corridor of high-rise building is put forward, and mathematic model of smoke flow in high-rise building. The results show that, for straight corridor, setting atria buffer zone the efficiency of mechanical smoke exhaust is about 3.6% higher than which atria buffer zone is not set, and smokeless zone is formed in the corridor nearby atria, and it is helpful to escaping from fire floor for people.
