소화약제 누기 감시장치의 모듈개발 및 성능검증에 관한 연구 = A Study on the Development of a Fire Extinguishing Agent Leakage Monitoring Module and its Performance Assessment

다국어 초록 (Multilingual Abstract)

One of the main problems with gaseous fire extinguishers is the decrease in fire suppression capability due to the leakageof the fire extinguishing agents, either naturally or caused by obsolete equipment. Therefore, in this study, a real-timedetector module for monitoring pressure leakages was developed and an assessment on its performance was carried out.
Currently, there are no domestic or global standards for testing pressure leakage detection systems. Therefore, similarglobal standards, such as ISO 7240 and FM 1421, and the domestic law on “Receiver type-approval and technical standardsfor product inspection” were used as a reference for assessing the performance of the newly developed module. Itsbasic performance was assessed by applying compressed air to the module, and, as a result, the minimum working pressurewas identified as 0.3 bar. Its environmental qualification was carried out to confirm the proper functioning of themodule in different climates and the module was confirmed to function properly at both high (50 oC) and low (−10 oC)temperatures.

가스계소화설비는 소화약제의 자연 누기와 소화설비 노후로 인한 누기 등으로 화재진압 능력이 저하되는 문제점이 발생하고 있다. 이에 본 연구에서는 소화약제의 누기를 실시간으로 감지하는 압력누기 체크센서 모듈을 개발하였으며, 개발 모듈에 대한 성능평가를 하였다. 국내 · 외적으로 압력누기 감시 시스템에 대한 명확한 시험기준이 마련되어 있지 않다. 따라서 국외 유사 기준 ISO 7240, FM 1421와 국내 수신기 형식승인 및 제품검사의 기술기준을 참고하여 개발 모듈에 맞게 기본 성능과 내환경성에 대한 기준을 마련하고 평가를 실행하였다. 기본 성능 평가는 압축공기를 모듈에 인가하는 방식으로 최저작동 압력이 0.3 bar인 것을 확인하였다. 내환경성 검증은 통상적으로 발생할 수 있는 기후변화에도오작동 없이 정상적으로 작동하는지를 확인하였다. 그 결과, 고온(50 oC) 및 저온(−10 oC) 환경 기준에서 이상 없이 정상작동하였다.
