가스계 소화설비의 제한사항 및 성능평가를 위한 배관 내 약제비율에 관한 연구

A Study on Percent Agent in Pipe as a Criterion to Evaluate Limitations and Performance of Gaseous Fire Extinguishing Systems

본 연구에서는 할론 1301 및 이산화탄소를 비롯한 가스계소화설비의 성능을 시험하고 평가하기 위한 가장 중요한 핵심 요소인 배관내 약제비율, 관경비 등 소화성능에 영향을 미치는 가스계소화설비의 제한사항 및 성능확보에 필요한 요소에 대하여 연구하였다. 또한 본 연구에서는 관련 국내외 기준 분석 및 국내 가스계소화설비의 성능평가에 관한 인정기준(KFIS 002)에 따른 시스템 성능시험을 실시하고 결과를 비교 분석하였다.

This study aims to investigate, review, and summarize the definition, development, and applications of "percent agent in pipe", "percent of agent in pipe" which is used as a key factor in testing and evaluating the performance of gaseous fire extinguishing agents, including Halon 1301 and <TEX>$CO_2$</TEX>. This study also analyzes and compares the local and international standards on testing and evaluating the performance of gaseous fire extinguishing systems, as well as the results of system performance tests conducted as a part of performance evaluation and approval programs for gaseous fire extinguishing systems, especially, Korean Gaseous Fire Extinguishing System Performance Approval Program called KFI Approval. Percent agent in pipe was defined first in NFPA 12A, Standard on Halon 1301 Fire Extinguishing Systems, dating back to the 1970's. After the phaseout of Halon 1301 systems in 1994 in the developed countries, the percent agent in pipe has been widely used in Halon 1301 alternative clean agent fire extinguishing systems, both halocarbon clean agent systems and inert gas clean agent systems, as an essential criterion to assure the system design accuracy, determine the limitations and performance of a system, and to predict the system performance results accurately, especially, in association with their system flow calculations. Underwriters Laboratories has their own standards such as UL 2127 and 2166 applying percent agent in pipe in testing and evaluating the performance of clean agent fire extinguishing systems. As a part of a system performance test and approval program called KFI Approval System, Korea also has started to apply the percent agent in pipe as a key factor to test, evaluate, and approve the performance of gaseous fire extinguishing systems, including both high and low pressure CO₂systems, from the early 2000's. This study outlines and summarizes the relevant UL and KFI standards and also describes the actual test resultant data, includi
