초록

FDS를 사용하여 대규모 클린룸에서의 화재에 대한 시뮬레이션을 수행하였다. 먼저 격자크기를 검토하여 크기가 $0.5{\times}0.5{\times}0.2m^3$인 격자를 사용하였다. 화재가 발생했을 때 온도와 가시거리, 일산화탄소의 성능위주설계 인명안전기준에 따라 안전을 확인하기 위하여 3개의 대규모 클린룸에서의 화재를 대상으로 하였다. 스프링클러가 작동하지 않는 경우에도 클린룸 모두 온도가 기준보다 낮아 안전함을 확인하였다. 또한 화재로 인한 가시거리의 감소와 일산화탄소농도도 무시할 수 있었다.

Cleanroom fires were simulated by using Fire Dynamics Simulator. A grid size of $0.5{\times}0.5{\times}0.2m^3$ was selected following review of grid sizes. Fires in three large cleanrooms were investigated to confirm safety by applying the requirements on temperature, visibility, and carbon monoxide concentration in performance based design. The worst situation without sprinkler system and air flow of 0.1 m/s downward in the cleamrooms was considered. It was confirmed that all the three cleanrooms were safe in case without sprinklers since the temperature was below the safety requirement. Decrease in visibility and carbon monoxide concentration due to the fires were negligible.
