Abstract

Purpose: The purpose of this study is to develop a sprinkler head that can be controlled and initial suppressed by installing it in a rack–type warehouse. Method: Considering the spray radius and spray pattern, various deflectors were designed, and the spray angle, discharge characteristics and protection performance test was conducted, and these results were compared and analyzed. Results: An optimal sprinkler head was developed to protect full load, front side of a commodity with minimum water volume 115L/min. Conclusion: The developed head of K-115 and 1Bar pressure was tested with one tier storage confirming that the fire control is carried out without burning all the loadings. In addition, the vertical distance from the top of the load to the deflector shall be separated by 450mm and installed to allow sufficient discharge to the outer part of the commodity.

연구목적: 적층형 물류창고의 랙크 내에 설치하여 화세제어 및 초기 진압이 가능한 스프링클러 헤드를 개발하고 이에 따른 성능확인 실험을 목적으로 한다. 연구방법: 살수반경과 살수패턴을 고려하여 여러 가지 디플렉터를 설계하고 살수각도 및 방사 시험 및 방호성능 실험을 수행하였으며 결과를 비교 분석하였다. 연구결과: 적재물 전체 및 전면부 방호가 가능하고 최소방수량 115L/min을 가지는 최적의 헤드를 개발하였다. 결론: 개발된 헤드는 방수량 K-115, 방수압 1Bar 조건에서 1단 소화실험 결과, 적용된 화재시나리오에서 적재물품을 전부 연소시키지 않고 화재를 제어함을 확인하였다. 아울러 적재물 상단에서 디플렉터까지의 수직거리는 450mm 이격하여 가연물 외곽부분으로도 충분히 방사되도록 설치해야 한다.
