Abstract

In restroom on high-rise building, exhaust system comprising the blower and duct is installed to discharge the odor and the water is suppled. Thus the restroom with fire and flame protection system may be used as refuge area in a fire situation. The study presents the smoke-proof system which operates such that the exhaust system to discharge the odor is converted to air supply system and appropriate pressure difference between the restroom and the accommodation is maintained. Also real-scale test facilities of smoke-proof system for refuge space using a restroom are installed on 5-story smoke control test building and experiments for evaluating the operational performance of smoke-proof system are carried out.

고층 건축물의 화장실은 평상시 악취 등의 배출을 위하여 송풍기와 풍도로 구성된 배기시스템이 설치되어 있으며 용수의 공급이 이루어지고 있어서 화염과 연기에 대한 방호기능만 추가되면 화재발생시 긴급한 피난공간으로 활용될 수 있다. 평상시 화장실의 배기용으로 사용하는 송풍시스템을 화재시 급기시스템으로 전환함으로써 기존 화장실의 연기에 대한 방호성능을 확보하는 화장실 방연시스템을 제안하였다. 또한 지상 5층 규모의 연기제어 실험동에 기존 화장실을 이용한 피난공간의 방연시스템에 대한 실규모 실험 시설을 설치하고, 화재발생 조건에 따른 작동성능 평가 실험을 수행하였으며 그 결과를 제시하였다.
