시험·조정·평가(TAB)를 통한 일반철도~도시철도역사 지하환승통로의 거실제연설비 현장 성능평가 및 개선방안에 관한 연구

Abstract

A purpose of this study is to analyze Testing Adjusting and Balancing(TAB), which is the field performance evaluation experiment of zone smoke control system, at a railway underground transit passage installed with zone smoke control system in an effort to find problems and improvements for ensuring performance. The TAB of smoke control system was classified into several procedures such as the design data review, duct leakage test, field measurement of airflow rate and velocity in fan and duct, Smoke Test. Through the duct leakage test, system leakage ratio was examined to prove the duct sealing. Improvement of the smoke control airflow problems due to lack of fan static pressure loss was secured performance. The performance of smoke control fan was secured by improvement of the smoke control airflow rate problems caused by loss of static pressure in intake duct. Smoke Test in smoke control zone confirmed that the damper operating schedule subject was influenced by natural wind or train wind. In conclusion, TAB of zone smoke control system in the experiments confirms the performance of zone smoke control system and provides evacuation time passengers of in the event of fire.
