Abstract
Purpose: The number of Cold Storages at home and abroad is on the rise, fires in large Cold Storages have recently occurred. As fires continue to occur and property damage is on the rise every year, the importance of preventing fires in large Cold Storage is growing. Method: Real Cold Storages were investigated on-site and fire cases were analyzed to derive and analyze fire risk, and the ORS, which is emerging as an adaptive fire prevention technology of Cold Storage, was investigated through FDS. Result: oxygen concentration 21, 15.7% and 17.7, 16.7% were analyzed through FDS, and flashover was reached within 3~4 minutes from 21, 17.7, 16.7%, but if oxygen concentration was lowered to 15.7%, it didn`t ignite for 13 minutes. Conclusion: This study understood the concept and general part of the ORS, modeled the freezer through FDS, and analyzed the oxygen concentration to analyze the fire protection adaptability of the ORS. In the future, it is expected that large-scale empirical experiments and related regulations will be prepared to provide solutions for fire prevention in Cold Storages in blind spots of fire.

연구목적: 국내외 냉장·냉동 창고 수는 증가 추세에 있으며 최근 잇따라 대형 냉장·냉동 창고의 화재가 발생하고 있다. 화재는 꾸준히 발생하고 재산피해액은 매년 증가 추세를 보여 대형 냉장·냉동 창고에서 발생하는 화재 예방에 대한 부분의 중요성이 커지고 있다. 연구방법: 실제 냉장·냉동 창고를 현장 조사하고 화재 사례 등을 분석하여 화재 위험성을 도출 및 그 특성을 분석하였으며 국외의 냉장·냉동 창고의 적응성 있는 소방기술로 대두되고 있는 저산소 화재예방시스템(ORS)에 대해 조사해 화재시뮬레이션(FDS)를 통해 냉동 창고 모델링을 진행하여 산소농도에 따른 화재성상을 분석하였다. 연구결과: 화재시뮬레이션을 통해 산소 농도 21%, 저산소 화재예방시스템 작동 상태인 15.7%와 추가로 17.7, 16.7%를 분석한 결과 21, 17.7, 16.7%상태에서 3~4분 이내에 플래시오버에 도달하였으나 산소농도를 15.7%로 낮춘 경우 13분간 화원을 가해도 착화되지 않았다. 결론: 본 연구에서는 저산소 화재예방시스템의 개념 및 전반적인 부분을 이해하고 화재시뮬레이션을 통해 냉동 창고 모델링하고 산소농도에 따른 분석을 진행해 저산소 화재예방시스템(ORS)의 화재방호 적응성에 대해 분석하였다. 앞으로 실대형 실증실험과 관련 규정이 마련되어 화재의 사각지대에 놓인 냉장·냉동 창고의 화재 예방에 대한 솔루션이 제공되길 기대한다.
