Purpose: The design fire sources based on the heat release rate of combustibles heavily influences the evaluation result of a performance-based design. The objective of the present study is to provide the information on the heat release rate for various combustibles in residential spaces. Method: Large scale calorimeter were used according to th amount of the combustibles. The combustibles were ignited using a small amount of fire source. The combustion gas generated in the experiment was collected inside the duct to measure the gas concentration(oxygen, carbon dioxide, carbon monoxide) and the heat release rate were calculated by the oxygen consumption method. The fire experiments were carried out with single combustible, simulated room and kitchen. Result: The results of these tests showed that the peak heat release rate were 1.2 MW for Kimchi refrigerator and 2 MW for Kitchen. In particular, a room had the highest fire risk in terms of the peak heat release rate, 2.8 MW. Conclusion: The design fire curve was proposed based on the heat release rate of the combustibles, which is expected to increase the reliability of the performance-based design in residential spaces.
연구목적: 건축물의 성능위주설계의 평가결과는 가연물의 연소실험으로 측정된 열방출률에 의해 크게 좌우된다. 본 연구는 주거공간의 성능위주설계의 신뢰성을 높이기 위해 주거공간의 가연물을 대상으로 화재실험을 실행하여 주거공간의 열방출률을 측정하였다. 연구방법: 화재실험은 대형콘칼로리미터시험기의 집연 후드의 아래에 주거공간의 가연물을 배치한 후에 소형화원으로 점화하여 산소소모법에 의해 열방출률을 측정하였다. 또한 화재실험은 주거공간 중에 방 공간과 부엌 공간으로 구분하여 가연물을 배치하고, 가연물을 점화원으로 점화하여 가연물의 화염형상 및 시간별 가연물 간의 화염전파를 관찰하였다. 연구결과: 부엌 공간과 김치 냉장고의 최대열방출률은 각각 2MW, 1.2MW이었다. 방 공간은 최대열방출률이 2.8MW로 크고 연소확대가 매우 빠른 것을 알 수 있었다. 결론: 주거공간 가연물의 연소실험을 통해 측정한 열방출률을 모델화하여 주거공간의 디자인 화재곡선을 제안하였으며 이는 주거공간의 성능위주설계의 신뢰성을 향상하는데 기여할 것으로 판단된다.
