 Abstract
Recently, Since buildings are bigger and higher, the damage of human life can be increased by fire flame and smoke in fire. Smoke control system is necessary to decrease this damage. Therefore, Air supply pressurization smoke control system is applied to vestibule of escape stairway. NFSC requires pressure differential of above 40 Pa, but pressure differential is excessively overpressure in the field. It is known that the cause of this over pressure differential is much leakage of damper. Over pressure differential can bad effect to escaper by pressurizing the door. Analyze the real leakage of damper by increasing the number of dampers operation for identifying this problems. The result of testing, the leakage has difference between new dampers and increased the number of operation dampers. As the static preassure increase, the leakage difference increase. Comparison with preceding study, this result has similar linear tendency.
