Abstract

The smoke control effect of mechanical pressurization system in the vestibule of the building is studied based on numerical simulation. The diversity of the actual air inlet setting of mechanical pressurization system is considered. The relative position of the air inlet and fire door opening is investigated in our research, which is divided into three cases: directly opposite, diagonally opposite, and perpendicular. The method of numerical simulation is used to study the influence of the relative position of the air inlet and door, as well as the installation heights of the air inlet of the fire-induced smoke prevention system. The smoke control effect in the case of fire and the cold state without fire is compared and analyzed; the setting position of the air inlet is optimized. The conclusion can provide technical references for smoke control design personnel, building fire protection design audit personnel, and the technical codes’ creators of smoke control and fire researchers.
