采用一维和三维相结合的数值模拟方法,分析了屏蔽门上设置可控风口的节能型屏蔽门系统的速度场和温度场,并对车站的换气量进行了校核。分析结果表明,车站站台、站厅的速度和温度都在乘客可以接受的范围内,换气次数能够满足地铁规范要求;采用这种节能型屏蔽门在过渡季能够满足乘客的舒适性要求,具有较好的节能效果,在降低车站能耗方面有实际的运用价值,可供地铁车站环控设计参考。
The speed field and temperature field of the energy-saving screen door system with controllable tuyere on the screen door are analyzed by the numerical simulation method combined with one-dimensional and three-dimension. The ventilation of the station is checked. The results show that the speed and temperature of station platform and station hall are both within the acceptable range of passengers, and the number of ventilation can meet the requirements of subway specification. This energy-saving screen door can meet the passenger comfort requirements during the transitional season with Better energy-saving effect, reducing the energy consumption of the station has practical value, for the design of environmental control loop metro station reference.
