| 摘 要： | 分析北方地铁屏蔽门系统节能效果,确定可有效利用活塞风的节能改造方案.采用EnergyPlus能耗模拟软件综合评价北方城市不同地铁环控方案,并利用Airpak模拟站台温度场和速度场预测改造后的效果.比较发现屏蔽门系统与安全门系统相比仅节能2%,在北方城市节能效果不明显.分析发现屏蔽门系统通风尤其是站台下排风能耗过高,过渡季节和冬季的活塞风是解决这一问题的关键.屏蔽门增加可调节的风口,可在过渡季节和冬季有效利用活塞风,引入站台可补充新风量,节省机械通风耗能,夏季关闭风口仍保留其节能优势,全年能耗可再减少30%,节能效果明显.

| Abstract: | To analyze the influence of the platform screen doors(PSD) on energy consumption of subway environmental control systems in northern cities and to make good use of piston wind,EnergyPlus,an energy analysis and thermal load simulation program,is used to evaluate such systems in northern cities.A computational fluid dynamics(CFD) simulation is made to model the velocity and temperature field of a subway station and to predict the effect on PSD reconstruction using Airpak. Compared to a system with automatic p... |
