Research on dynamic thermal comfort evaluation of passengers in underground railway station

Analyses the characteristics of underground railway station environment and the change of thermal comfort of passengers when they are in and out of the station. According to the features of public area in underground railway station, taking an underground railway station in Nanjing as a research object, analyses and studies the thermal comfort conditions in different seasons and different evaluation parts by field tests, questionnaires and dynamic thermal comfort evaluation model RWI/HDR. Obtains the thermal comfort of passengers in different conditions. The results show that the method combining thermal sensation vote with relative warmth index (RWI) can accurately evaluate the thermal environment of underground railway station. Presents a temperature-dynamic-control model combined with existing BAS of this underground railway station.
