Abstract

Purpose: Recently, cold storage have appeared in large and complex. At the same time, cold storage fires continue to occur every year. Cold storage are buildings with a high risk of fire diffusion, and early detection is required to minimize damage. However, due to the low-temperature environment, it is difficult to apply a detector, so it is defined as the subject of exclusion from the installation. In this study, based on the performance evaluation and field investigation of air sampling detectors, we intend to prepare a plan to secure the adaptability of detectors in low-temperature warehouses. Method: A scenario was constructed by analyzing the operating characteristics of the air sampling detector in a low-temperature environment. Three scenarios were developed and performance evaluation was performed. Result: Fire recognition was insensitive in a low-temperature environment, and the sagging phenomenon of the sampling pipe was noticeable. In addition, it was confirmed that condensate was generated due to the temperature difference between the inside and outside the warehouse. Conclusion: A plan to secure adaptability for the application of air sampling detector was presented, such as setting alarm threshold values, countermeasures condensate and condensation.

연구목적: 최근 냉장·냉동 창고가 대형 및 복합화되어 나타나고 있다. 동시에 냉장·냉동 창고 화재가 매년 지속적으로 발생한다. 냉장·냉동 창고는 화재 확산 위험이 큰 건축물로, 피해를 최소화하기 위해서는 조기 감지가 요구된다. 하지만 저온 환경의 특성상 감지기 적용이 어려워, 설치 제외 대상으로 규정된다. 본 연구에서는 공기흡입형 감지기를 대상으로 성능평가 수행 및 현장 조사한 내용을 바탕으로 저온 창고 내 감지기 적응성 확보 방안을 마련하고자 한다. 연구방법: 저온 환경 내 공기흡입형 감지기의 작동 특성을 분석하여 시나리오를 구성하였다. 3가지 시나리오를 개발하였고, 성능평가를 수행하였다. 평가 내용과 실제 현장을 조사한 내용을 비교·분석하였다. 연구결과: 저온 환경에서 화재 인식이 둔감하며, 공기흡입관의 늘어짐 현상이 눈에 띄게 나타났다. 또한 창고 내·외부 온도 차로 인해 응축수가 발생하는 것을 확인하였다. 결론: 저온 특성을 반영한 경보임계값 설정, 응축수 및 결로 대응 방안 등 냉장·냉동 창고 내 공기흡입형 감지기 적용을 위한 적응성 확보 방안을 제시하였다.
