It is found that: the standard Model can be used to predict flows at the station and resultant velocity and temperature field under some reasonable presumptions; the impact brought by stopcock wind is variable according to the different tunnel structures; the temperature of is related with the distribution of heat load; the VAV system has advantage in energy saving, but when the air volume reduced to a certain degree, we should consider the alteration of rising the temperature of supply air, and increasing the quantity of it.

研究表明：采用合理的假设，标准的湍流模型能够较为准确地模拟和预测地铁站台的温度场与速度场；活塞风对站台的影响随区间形式的不同而不同；空调送风温度的设定与负荷的分布情况有密切的关系；针对站台空调季全天的负荷变化，VAV环控方案可以达到节能的目的，但在风量过小时，适当考虑采用提高送风温度，加大送风量的方法进行局部的调整。
