地铁车厢内热环境现状调查研究
Investigation on indoor thermal environment of underground railway trains
摘要：
以沈阳、北京、上海、广州4个城市典型地铁线路的地铁车厢热环境为研究对象，进行了车厢内冬、夏季热环境参数的现场测试和乘客热感觉的主观问卷调查。通过对现场测试和问卷调查结果的统计分析，得出了各城市地铁车厢内热环境及乘客热感觉的现状，给出了各城市地铁车厢的热中性温度及80%接受率下的可接受温度范围，为地铁热环境的设计和改善提供依据。
Abstract：
Taking the indoor thermal environment of underground railway trains in typical lines in Shenyang, Beijing, Shanghai and Guangzhou as study objects, performs the field test of thermal environment parameters and the subjective questionnaire in the trains in winter and summer. Obtains the current situation of thermal environment and passenger’s thermal sensation in underground railway trains in different cities by statistical analysis. Gives the thermal neutral temperature and the acceptable temperature range under 80% acceptance rate in the trains, which can provide foundations for the design and improvement of thermal environment in underground railway trains.
Keywords:underground railway train, thermal environment, field test, questionnaire, thermal neutral temperature, thermal sensation, acceptable temperature range
