요약
본 연구에서는 상수도 직결형 스프링클러 시스템의 성능을 평가하기 위하여 실물 주택을 대상으로 화재 실험을 수행하였다. 실물 주택의 크기는 $56m^2$이며 거실, 주방, 방으로 이루어져 있으며, 화재는 대두유가 과열되어 자연발화가 발생하여 일어나게 하였다. 상수도 직결형 스프링클러시스템의 성능을 확인하기 위하여 주방에 스프링클러시스템을 설치하였다. 실험결과 주방에서의 발화로 시작된 화재는 주방천장까지 확대 되었으나 스프링클러가 동작하면서 화재는 진압되었다. 스프링클러가 동작할 때의 상수도 압력은 0.28 MPa이었으며 이 결과로서 일반 주택의 상수도압력으로도 소화가 가능함을 확인할 수 있었다.
Abstract
In this research, full-scale fire test was performed on a real house for the evaluation of the performance of waterworks direct-coupled sprinkler system. The fire was set to occur as spontaneous combustion as the cooking oil overheats. The size of house is $56m^2$ and it consists of a living room, a kitchen, and a room. In order to verify the performance of waterworks direct-coupled sprinkler system, it was installed in the kitchen. The result of the test showed that the fire started from the kitchen enlarged up to its ceiling but it was soon exhausted as the sprinkler started to work. The pressure of the waterworks was 0.28 MPa when the sprinkler operated, by which it verified that fire could go out even by waterworks pressure of the general residence.
Key Words: Waterworks direct-coupled sprinkler system, Full-scale fire test, Waterworks pressure
