Abstract

The Ministry of Environment established a guide line Indoor Air Quality Management guidelines in Public Facilities in December 2006. As the items of the guideline, $CO_2$ (Carbon dioxide) and PM10 (Particulate matter). Therefore trains and subway need to control air quality. The indoor thermal environment in passenger car is very important for the enhancement of the amenity and health of passengers. Many researchers have studied it not for train but for building. So, in this study, we have performed thermal environment in passenger car (KTX, Mugunghwa, Saemaeul), and verified the relation between the PMV (Predicted Mean Vote) and PPD (Predicted Percent Dissatisfied) from September to October 2007. As a result, the average PMV value for each trains are 0.1, 0.22 for KTX, 0 for Mugunghwa, 0.1 for Saemaeul. So it satisfies the ASHRAE Handbook thermal environmental limit (-0.5 < PMV < +0.5).
