An Experimental Study on Pressurization Smoke Control System in Staircase
Influence of a Dynamic Pressure Control System and Opening Vestibule Doors and Confirmation of Differential Pressure Adjustment Damper Performance
We conducted a full-scale experiment aimed at gathering useful knowledge for planning staircase pressurization for smoke prevention and exhaust, assuming a seven-story office building. We conducted an experimental study on dynamic pressure effects resulting from the installation of the dynamic pressure control system, confirm pressure variation in staircases resulting from opening doors to vestibules, and also confirm the performance of differential pressure adjustment dampers in staircases. The following results are obtained:
When the air inlet and the opened doors are on the same floor, the effect of the dynamic pressure control system is small. When a floor that opening the doors is moved away from the air supplied floor, it shows that installing a dynamic pressure control system reduces the influence of dynamic pressure near air inlet by about 54%.
Opening doors both staircases and vestibules did not have a large effect on pressure variation within staircases; rather, pressure conditions within staircases tended to be maintained.
To implementing smoke control by staircase pressurization, installing only a single differential pressure adjustment damper in staircases maintains a higher pressure than the setting for differential pressure adjustment damper (60 Pa), possibly obstructing door opening.
This study thus provides basic information for planning staircase pressurization aimed at smoke prevention and control.An Experimental Study on Pressurization Smoke Control System in Staircase
