地铁采用屏蔽门及变频节能技术浅探

本文在分析我国近年来东南部主要城市已建成地铁工程实例的基础上,对地铁通风采用屏蔽门系统与闭式系统不同模式下的冷负荷以及主要通风设备采用变频调速技术的节能效果进行了统计分析与对比计算,其分析结论经过多年运行实践检验,基本符合地铁实际情况,目前,屏蔽门系统与变频调速技术已在我国地铁设计中广泛采用,成为重要的节能措施之一。

Brief Studyon Metro Using PSD and VF Energy-saving Technology

Based on analysis of China＇s southeast coastal region major cities＇ metro construction cases in recent years, this paper made statistical analysis and comparative calculations on cooling loads of metro ventilation using PSD（platform screen doors） and using the closed system under different modes and on energy-saving effect of the main ventilation equipment using VF （variable frequency） speed regulation technology. The analysis result is verified through years of operation practice that satisfied the actual metro situation, PSD system and VF speed regulation technology have been widely used in China＇ s metro design and have become the important energy-saving measures.
