两种站台门系统对天津地铁侧式站台冬季内部环境的影响
Impact of two kinds of platform edge door systems on environment of a side-platform station in Tianjin in winter
摘要：
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。
Abstract：
With the numerical simulation method, establishes the model of automatic sliding door and platform screen door system with vents for the side-platform station, and verifies the accuracy of the model through field testing. Based on the simulation, obtains the temperature field, velocity field, PMV and PPD. Compares the two kinds of door systems, and the results indicate that in the side-platform station, the comfort of platform screen door system with vents is superior to that of automatic sliding door system in the north with longer non-air conditioning season due to the better uniformity of temperature and velocity.
