스크린도어 설치에 따른 지하철 터널환기시스템 개선사항 도출을 위한 고찰

This report is for considering ventilation system in subway tunnel after PSD(Platform Screen Door) installation. It was planed that PSD will be installed in every subway station until 2010. PSD is for passengers safety, clean environment in platform and energy saving. In the contrast to cleaning effect at subway platform, it is getting used to be contaminated and accumulated by dust in subway tunnel which is particulate matter from subway operation. Contaminated air is coming into subway platform and inside of the train as PSD opens. Also PSD installation leads to a result that natural ventilation system through platform is blocked by PSD. Therefore we suggested active ventilation system with space separator that would be one of the solutions for clean environment in subway tunnel after PSD installation.
