초록

본 연구에서는 지하공간에서 화재 발생시 배연장비의 연기배출 성능을 평가하기 위하여 실험을 실시하였다. 배연장비로는 이동식 송풍기를 사용하였으며 가연물질로는 에탄올을 사용하였다. 한 변의 길이가 80cm의 정사각형 화원을 사용하였으며 최대 열방출률은 약 460 kW이다. 급기방식 배연의 영향을 평가하였다. 급기방식의 경우 실내의 가시도 향상 및 온도감소 효과를 확인할 수 있었다.

In this study, experiments were conducted to evaluate the effectiveness of ventilation equipment in underground fires. Two type of Ventilators were used in experiments. Experiments were carried out using ethanol square pool fire. Maximum heat release rate was about 460kW. Visibility and temperature distribution were evaluated according to mechanical ventilation. In blower type ventilation, visibility was increased and temperature was lowered.
