采用数值模拟方法对侧式站台的半高安全门和带风口屏蔽门系统建模,通过实测数据验证了模型的准确性。对2种站台门系统进行模拟计算,得到空间的温度场、速度场,以及PMV,PPD值,并进行对比。结果表明,在非空调季较长的北方地区,带风口屏蔽门系统在站台候车区域温度、速度分布更加均匀,其舒适性优于半高安全门系统。
The numerical simulation method was used to model the semi-high safety doors and the screened-gate doors with side vents. The accuracy of the model was verified by the measured data. The simulation and calculation of the two kinds of platform door system, the space temperature field, velocity field, and PMV, PPD values, and compared. The results show that in the northern part of the non-air-conditioned season, the air-inlet screen-door system has more uniform temperature and velocity distribution in the station waiting area, and its comfort is better than that of the semi-high safety door system.
