Abstract

Ventilation fans utilized correctly can increase the effectiveness of fire fighters and survivability of occupants. It is possible to increase the pressure of a corridor to prevent the infiltration of smoke. In this study, experiments were carried out to evaluate ventilation effectiveness in corridor fires. Corridor used in the experiment was 20 m long. Heptane was used as a fuel. Temperature and visibility were measured in order to evaluate ventilation effectiveness according to the position of a vent. Vent distance ranged from 0 m to 4 m and height varied from 0 m to 1.5 m. When the vent was positioned 2 m long and 0.75 m high the result was most effective.

배연장비가 적절하게 사용된다면 소방활동의 효율성을 증가시키고 실내 피난자의 피난활동을 원활히 할 수 있는 장점을 가지고 있다. 복도공간 화재 시 복도공간의 압력을 양압 상태로 만들어 연기의 이동을 억제해 소방활동 및 피난활동을 돕는 역할을 한다. 본 연구에서는, 배연차를 사용하여 복도공간 내 화재 시 배연성능을 평가하기 위하여 20m 복도공간을 제작하여 실험을 실시하였다. 가연물로는 헵탄이 사용되었다. 실내 온도분포와 가시도를 측정하였으며 송풍구의 위치에 따른 배연성능을 평가하였다. 송풍구의 설치 높이(0m, 0.75m, 1.5m) 및 거리(0~4m)에 따른 영향을 평가하였다. 송풍구를 출입구로부터 2m, 0.75m 떨어진 위치에 설치하였을 때 가장 우수한 효과를 보였다.
