Abstract

This study investigated the pressure change in the fire room and elevator lobby during the air pressurization to the Elevator lobby with the various egress scenarios and the existence of vent holes in the fire room. The experiments revealed that pressure change was significantly affected by the open/closure scenarios of the front door and stairway door resulting in over pressure, under pressure and performance drop of the door closure. It also revealed that the required smoke defensive air velocity can be obtained only with the existence of vent holes in the fire room by the removal of back pressure in the fire room.

본 연구에서는 공동주택 화재 시 피난시나리오 및 화재실 배연개구부 유무에 따른 부속실 급기가압 시스템의 성능 및 효용성을 평가하기 위해 각 실의 압력변화 특성을 실험적으로 측정하였다. 그 결과, 화재실문과 계단실문 개폐 시나리오 및 배연개구부의 유무에 따라 압력변화 특성이 크게 달라졌으며 최저설계차압으로 재안정화 되기 전에 부속실 과압 또는 부압 발생, 도어클로져 닫힘 기능 저하 등의 현상이 나타났다. 또한. 급기댐퍼의 설치위치보다는 화재실 배연개구부의 존재가 규정방연풍속 유지에 필수적인 것으로 나타났다.
