摘要

屏蔽门渗透风量是影响地铁车站冷负荷的重要因素。提出一种屏蔽门渗透风量计算模型，基于测试风速分析，对屏蔽门单周期渗透风量进行量化，分不同位置和不同阶段研究屏蔽门渗透风的特征，通过对列车运行因素进行分析，建立一种屏蔽门渗透总风量的计算方法，以期对地铁车站的设计计算及运营等工作提供借鉴。结果表明：不同位置屏蔽门的渗透风速不同，沿着列车的运行方向，屏蔽门单周期渗透风速和风量都随门位置的变化而减小，出站侧的屏蔽门单周期渗入风量约为进站侧的65%；不同阶段屏蔽门渗透风量也存在差异，列车停靠阶段单周期渗透风量最大，为进站阶段的10倍左右；确定了屏蔽门单周期渗透风量的范围，并提出相应的计算模型，据此计算得到地铁车站屏蔽门全天的渗透风量。

Abstract

The infiltration air volume of platform screen doors (PSD) is an important factor affecting the cooling load of subway station. This paper proposes a calculation model of infiltration air volume of PSD. Based on the analysis of test wind speed

the single cycle PSD infiltration air volume is quantified

and the characteristics of infiltration air volume of PSD are studied in different positions and stages. Then

through the analysis of train operation factors

a calculation method of total infiltration air volume of PSD is established

in order to provide reference for the design and operation of subway station. The results show that: （1） the infiltration wind speed of PSD at different positions is different. Along the running direction of the train

the infiltration wind speed and air volume of PSD in a single cycle decrease with the change of door position. The single cycle infiltration air volume of PSD at the exit side is about 65% of that at the entrance side. （2） There are also differences in the infiltration air volume of PSD in different stages. The total infiltration air volume in a single cycle in the train stopping stage is the largest

which is about 10 times that in the train arrival stage. （3） The range of infiltration air volume of single cycle PSD is given

which provides a basis for the calculation of total infiltration air volume

and the corresponding calculation model is proposed

which can calculate the whole day air volume of PSD penetration of subway station.
