The Effects of Smoke Ventilators on the Fire Mitigation in a Compartment

On occurring fire of high-rise building, smoke vent window may not operate effectively depending onstructural characteristics of buildings and outdoor air conditions, as noted in some literature. Therefore, in this studyit reviewed the exhaust effect of ventilation system considering outdoor air conditions. Also, reviewed the influencerelated to the temperature changes inside compartments of ventilation system with the effective area of smoke ventwindow and the exhaust capacity of ventilator as variables. The fire analysis using Fire Dynamics Simulator (FDS)was conducted for this study. The result showed that the temperature rise of fire compartments can be delayed by theinflow of outdoor air and the delayed effect seems to be affected by total exhaust quantity of ventilation system
