도시철도 객실용 공기청정시스템 개발 현황

초록

The aim of this study is to develop the air cleaning system reducing harmful indoor air pollutants, such as particulate matters (PM10, PM2.5), carbon dioxide (CO₂), volatile organic carbons (VOCs), formaldehyde (HCHO), and etc. in a urban railway cabins. Indoor air of urban railway cabin should be treated by HVAC system in order to satisfy passengers thermal comfort and at the same time to protect their health. We analyzed a clean air volume by checking the interior volume of a cabin and the number of passengers to design capacity of air cleaning system. The prototype air cleaning system is developed as a single unit which could be installed into the railway cabin. The system is under evaluation in terms of cleaning efficiency, pressure decrease, and long-term operability in static test cabin. In addition, the efficiency of system will be evaluated using operating cabin with the help of Seoul Metro.
