铁路客站无组织渗风现状调研及数值模拟研究
Current situation investigation and numerical simulation study of natural air infiltration in railway stations
摘要：
通过对全国16个大型铁路客站现场调研，总结了客站主要空间的无组织渗风现状及特点，归纳了目前控制无组织渗风的节能做法。通过调研发现，由于客站建筑及使用特点，大量的无组织渗风量增加了夏季空调和冬季供暖能耗，并且影响室内热舒适。通过数值模拟方法，分析了门斗和空气幕对客站无组织渗风的控制效果，并对各自控制无组织渗风的特性给出了评判和使用建议。
Abstract：
Based on investigation of 16 large railway stations, summarizes the current situation and characteristics of natural air infiltration in main spaces, and concludes some energy saving measures. The survey results show that most railway stations fail to control the natural air infiltration because of its large and open characteristics which leads much more energy consumption in cooling and heating seasons, and worse indoor thermal comfort. Simulates and analyses the efficiency of air curtain and anteroom in controlling the natural air infiltration and gives suggestions based on their different controlling characteristics.
