초록

자동차의 엔진룸의 내부를 살펴보면 여러 가지의 장치 및 장비가 복잡하게 설치되어 있고 각종 오일 등의 인화물질을 포함하고 있어 재발화 가능성이 매우 높다. 또한, 폭발가능성도 높기 때문에 운전자나 탑승자가 보닛을 열고 엔진룸에 직접 분말 소화기를 분사하는 방식으로는 한계가 있다. 따라서 엔진룸 내부에서 화재를 감지하여 소화약제를 분사한 뒤, 화재를 진화하는 소화시스템과 엔진룸 내부의 고열에 견딜 수 있고, HFC-227ea를 포함하는 충분한 점성을 가진 폼 형태의 소화약제를 개발 및 시험하였다. 그리고 포소화약제가 가지고 있는 소화원리인 질식 및 냉각효과와 HFC-227ea가 가진 부촉매효과를 동시에 이끌어 내고, 소화 후에도 분말 소화기처럼 잔존물에 의한 2차 피해가 없는 맞춤형 소화약제를 개발하였으며, 차량을 이용한 충돌실험을 통하여 방출이 완료된 후에도 이물질 없이 소화약제를 제거할 수 있는 장점이 존재하는 실험결과를 획득하였다.

Several complex devices and equipments are installed in the car's engine room, including various kind of oils or other flammable materials. So re-ignition is very likely to take place in it. In addition, it is restrictive for the driver or the occupant to open the bonnet and to spray the fire extinguisher in the engine room due to the high possibility of explosion. Therefore, a fire extinguishing system, which can detect a fire and inject the fire extinguishing agent to extinguish it, and fire extinguishing agents including HFC-227ea, which can stand the high temperature within the engine room and hold the viscosity sufficient to keep it in the kind of foam, were developed and tested. And the suffocation effect and the cooling effect come from the fire extinguishing principle of the foam fire extinguishing agent and the inhibiter catalyst effect come from the one of HFC-227ea was led simultaneously, and fire extinguishing agents without the secondary damage caused by residuals after the fire extinguishment like a case of the powder fire extinguishing agent, were developed. And experiments using a vehicle collision after the discharge is complete, foreign material can be removed without extinguishing the advantage that experimental results obtained.
