Study on Thermal Comfort of Beijing Subway in Summer

As the core means of transportation of modern large cities, the subway provides a good guarantee for the overall development and operation of large cities. But in the process of subway development, the passenger’s thermal comfort has been neglected. There are few studies on subway thermal comfort at present. In this paper, the thermal comfort of passengers was investigated while the thermal environment was tested. The results showed that the temperature of the carriage reached the lowest in the summer, carriage compartment temperature 10 °C lower than outdoor temperature, the average temperature of import, station hall, the platform, and carriage is respectively: 27.9 °C, 27.2 °C, 26.6 °C, and 25.6 °C, respectively. The thermal sensation of passengers generally changes in a V shape, that is, the thermal sensation becomes lower during the arrival process and higher during the departure process, which is similar to the temperature change trend.
