摘　　要：现行标准中对于地铁车厢内温度场的评价,主要在车辆静止及空载情况下评价室内平均温度及各个测点断面温度差值。通过对某地铁列车的全天跟踪实测,获得运营中地铁列车车厢内的实测温度数据。在此基础上,分析了空载与载人时段、不同位置高度以及人员密度等因素对室内温度场的影响,得出了较为合理的车厢温度分布特性,从而为优化车厢内温度控制策略、提高乘客舒适度打下基础。Accordingto the current standards for the temperature field in metro train,when a train stands still without any load,the indoor average temperature and the temperature difference between different measuring points are the main evaluation index.Based on the all-day tracking test of a metro train,the measured temperature data are obtained.On this basis,factors of different time periods of theloaded and unloadedmetro car,diferent position heights and passenger densities that influence the temperature distribution inside the train are analyzed,a reasonable temperature distribution character is drawn from this reseach,which will help to optimize the temperature control strategy and improve the thermal comfort in metro train.
