Smoke Control Dampers; 135° opening angle; anti-backflow technology; international standards (EN 12101-2; NFPA 92); CFD simulation.Abstract
Based on international standards (ISO 10294:2017, EN 12101-2:2003, NFPA 92), this paper proposes a fire smoke exhaust window design with a 135° opening angle, focusing on addressing the risk of backflow in high-wind-pressure environments. Through a multi-stage hinge system and dynamic sealing technology, the smoke exhaust efficiency is improved by 50% under extreme conditions, and its performance is verified through CFD simulation and wind tunnel experiments. This research provides an innovative solution for active smoke exhaust systems in high-rise buildings.
