제연 TAB를 통한 철도 지하환승통로의 거실제연설비 성능평가

A Performance Evaluation of Zone Smoke Control Systems for Railway Underground Transit Passage by Smoke Control TAB

  • 16

본 연구에서는 거실제연설비가 설치된 철도 지하환승통로에 현장성능평가시험인 제연 TAB(Test, Adjusting, Balancing)를 실시하여, 제연설비 성능 확보에 미치는 영향을 분석하고 개선방안을 도출하였다. 제연 TAB는 지하환승통로의 제연설비 설계자료 분석, 제연덕트 누기테스트, 제연송풍기와 덕트의 풍량 및 풍속 측정, Smoke test로 나누어 진행되었다. 제연덕트 누기시험을 통해 누기율을 측정하여 덕트의 기밀성을 확인하였고, 흡입측 덕트 정압손실로 인한 제연풍량 부족의 문제점을 개선하여 송풍기의 성능을 확보하였다. 또한, Smoke test을 통해 예상제연구역별 제연댐퍼 동작 시 자연풍, 열차풍 영향으로 인한 문제점을 분석하고 개선하여 예상 제연구역 내 제연이 원활하게 이루어짐을 확인하였다.

This study conducted Testing, Adjusting, and Balancing (TAB), which is a type of field performance evaluation experiment of a zone smoke-control system, at a railway underground transit passage installed with a zone smoke- control system to find problems and improvements for ensuring performance. TAB for the smoke control system was classified into several procedures, such as design data review, duct leakage test, field measurement of the airflow rate, velocity of the fan and duct, and a smoke test. Through the duct leakage test, the system leakage ratio was examined to prove the duct sealing. The iImprovement of the smoke control airflow problems due to the lack of fan static pressure loss was the secured performance. The performance of the smoke control fan was secured by improvements of the smoke control airflow rate problems caused by the loss of static pressure in the intake duct. The smoke test in the smoke control zone confirmed that the damper operating schedule subject was influenced by natural wind or train wind.
