可调通风型站台门系统节能效果分析
Energy saving effect of adjustable ventilation platform door systems
摘要：
可调通风型站台门系统结合全封闭站台门和安全门2种系统形式的优势，具有较好的节能效果，在地铁工程领域得到了广泛应用。利用STESS模拟的方法，对不同开启面积下可调通风型站台门系统的通风量进行了模拟研究，结果表明：随开启面积增加，通风量逐渐趋于稳定；单侧站台门开启面积达到24 m2时，通风量可达到最大值的95%。基于通风量模拟，对夏热冬冷、夏热冬暖地区该系统的节能量进行了逐时计算分析，认为可调通风型站台门系统在夏热冬冷地区低负荷地铁车站节能效果较好，全年可节电约1.3万kW·h/站。
Abstract：
The adjustable ventilation platform door system combines the advantages of platform screen door system and platform safety door system, which has good energy saving effect and has been widely used in underground railway engineering field. Simulates the ventilation rate of the adjustable ventilation platform door system under different opening areas by STESS. The results show that the ventilation rate gradually tends to be stable with the increase of the opening area, and the ventilation rate can reach 95% of the maximum value when the opening area of the single side platform door reaches 24 m2. Based on the ventilation rate simulation results, calculates the energy saving rate of the system in hot summer and cold winter zone and hot summer and warm winter zone. The adjustable ventilation platform door system has better energy saving effect in low cooling load underground railway stations in hot summer and cold winter zone, and the annual power saving is about 13 000 kWh per station.
