역사 승강장의 스크린도어가 실내공기질 및 지각공기질에 미치는 영향

Previous researches than that screen doors (PSD) significantly reduce indoor fine particle concentration in subway platforms. However, changes at platform space can influence not only IAQ, but also Perceived Air Quality. Field measurements consisted with PM10 monitoring and questionaire were carried out to quantify the influences at screen doors. As a result, we can obtain that the difference of space recognition can have greater influence on the air quality that passengers feel than the actual concentration of PM10.
