요약
본 연구는 풍도, 부속실, 거실 그리고 계단실로 구성된 구조물의 제연설비 성능에 관한 연구를 수행하고 급기 가압실의 안전성을 구현하기 위한 실험 자료를 구축하고자 하는데 목적이 있다. 이를 위해서 부속실 가압 및 차압 조절 설비와 방화문의 개폐력 측정 장치를 제작하였다. 본 주제는 부속실의 가압을 위한 설계유량과 폐쇄시 차압이 동일한 경우 방화문의 크기와 닫히는 각속도 증가에 따라서 폐쇄력을 분석하였다. 실험 결과 방화문의 크기와 닫히는 각속도가 증가 할수록 폐쇄력이 증가하였으며, 일정 각속도 이상으로 증가할 경우 폐쇄력이 일정하게 유지되는 임계각속도가 존재하는 것을 확인하였다.
Abstract
This study aims to construct the performance data for smoke-control zone and realize the safety of injection and pressurization room which is composed of supply air pressure zone, vestibule, smoke-control zone and stairwell. To obtain this, smoke-control system and the device of the opening-closing force of fire door are manufactured. This subject is the analysis of the closing force, angular velocity and fire door size in the case of fixed volume flow rate. Based on the results, closing force increased as fire door size and closing angular velocity increases. Also, it is remark that there exists a critical angular velocity, which maintains constant maximum closing force even though the angular velocity increases more.
Key Words: Smoke-control zone, Vestibule, Closing force, Critical angular velocity
