신분당선 전동차 실내공기질 향상에 관한 연구

Everyday metro is main transportation used millions of passengers who stays at least 30 minutes or more than 1 hours in rolling stock cabins. Most of subway ventilation systems are formed in complicated underground sections which indoor air quality of station lobby, platforms, and rolling stock cabins some factors are causing amenity and passenger’s health. The inflowing dusts(PM10) inside the tunnel are blocked by installed PSD(Platform Screen Door) at platforms in Shinbundang Line. Also by the ventilation systems are installed which fresh air are supplied by in-outdoor air and exhausting CO₂. The passengers breath and dust concentration from the inside tunnel could change the air of rolling stock cabin. This paper will analyze concentration change of CO₂ due to passengers breath and PM10, furthermore reduction measures of CO₂ and PM10 concentration in Shinbundang Line.
