Abstract
Purpose: Recently, the number of logistics warehouses has been on the rise. In addition, as the number of such logistics warehouses increases, number of fire accidents also increases every year, increasing the importance of preventing fires in large logistics warehouses. Method: investigated aspirating smoke detectors that are emerging as adaptive fire detectors in logistics warehouses. Then, through fire simulation (FDS), logistics warehouse modeling was conducted to compare and analyze the detection speed of general smoke detectors and aspirating smoke detectors according to four stages of fire growth and three locations of fire in the logistics warehouse. Result: Growth speed in Slow-class fires and Medium- class fires, the detection speed of aspirating smoke detectors was faster regardless of the location of the fire. However, in Fast-class fires and Ultra-Fast-class fires, it was confirmed that the detection speed of general smoke detectors was faster depending on the location of the fire. Conclusion: It was confirmed that the detection performance of the aspirating smoke detector decreased as the fire growth speed increased and the location of the fire occurred further than the receiver of the aspirating smoke detector. Therefore, even if an aspirating smoke detector is installed in a warehouse that stores combustibles with high fire growth rates, it is judged that an additional smoke detector is attached far away from the receiver of the general smoke detector to increase fire safety.

연구목적: 최근 물류 창고 수의 증가 추세에 있다. 또한 이러한 물류 창고의 수가 늘어남에 따라 화재발생건수 또한 매년 증가 추세를 보여 대형 물류 창고에서 발생하는 화재 예방의 중요성이 커지고 있다. 연구방법: 물류 창고에 적응성 있는 화재감지기로 대두되고 있는 공기흡입형 감지기에 대해 조사하고 화재시뮬레이션(FDS)를 통해 물류 창고 모델링을 진행하여 물류창고 화재 성장 속도 4단계와 화원 위치 3가지에 따른 일반 연기감지기와 공기흡입형 감지기의 감지 속도를 비교 분석하였다. 연구결과: 성장속도 Slow급 화재와 Medium급 화재에서는 화원위치에 상관없이 공기흡입형 감지기의 감지속도가 더 빨랐다. 하지만 Fast급 화재와 Ultra Fast급 화재에서는 화원위치에 따라 일반연기감지기의 감지속도가 더 빠른 것을 확인할 수 있었다. 결론: 공기흡입형 감지기는 화재성장속도가 빨라질수록, 둘째 화원의 위치가 공기흡입형 감지기 수신부보다 멀어질수록 같은 위치에 있는 연기감지기보다 성능이 낮아지는 것을 확인할 수 있었다. 그렇기에 화재성장속도가 빠른 가연물을 적치하는 창고에서는 공기흡입형 감지기를 설치하더라도 공기흡입형 감지기의 수신부와 멀리 떨어진 위치에는 연기감지기를 추가로 부착하는 것이 화재 안전성을 높이는 방법이라고 판단된다.
