초록

목조한옥은 가연성의 재질로 구성되어 있어 화재라는 측면에서 취약하며, 방화의 경우 화재의 성상 초기부터 화원의 규모가 다양하게 나타날 수 있다. 본 연구는 국내 목조문화재의 화재 소화에 적용하고 있는 저압의 미분무 소화시스템의 소화성능을 확인하기 위하여 소화실험을 수행하였다. 소화실험의 유형은 화원의 규모별 및 한옥의 규모별로 구분하였고 소화시간을 확인하여 소훼의 정도를 평가하였다. 실험결과 소화성능이 문화재 규모에서 중요한 차이는 없었으며, 화원의 규모가 0.5단위 이하의 작은 화재에 대하여 소화효과가 나타났고, 화원의 규모가 1단위 이상에서는 소화능력이 현저히 부족하였다. 실제 목조문화재의 화재 성장 환경이 소화실험 모형보다 취약하다는 측면을 고려해볼 때, 미분무 소화설비를 목조한옥에 대한 범용 자동소화설비로 적용하기 위하여 소화성능 면에서 충분한 검증이 요구된다.

The study verified the extinguishing performance of the low pressure water-mist system, which is used to extinguish fire at domestic wooden architecture, through a fire test. Made of inflammable materials, a wooden house is vulnerable to fire, and the size of fire may vary from the early stage in case of arson. With the discharging pressure of 8 bar and the flow rate of 35 lpm, the low pressure water-mist nozzle used in the experiment has considerable discharging amount compared to other water-mist nozzles. The extinguishing performance was tested based on the size of fire and architecture. Test results demonstrated that the extinguishing performance was not affected by the size of a house, but decreased significantly when the size of fire was above unit 1. Taking into account that the environment of actual wooden cultural properties is more vulnerable than that of the experiment model, sufficient investigation on extinguishing performance is required to apply the water-mist extinguishing system to wooden architecture.
