摘要
严寒寒冷地区的高层建筑内存在很强的烟囱效应,外门开启时大量冷风侵入,会造成门厅温度低、风速大、能耗大.通过分析计算和实测研究,提出应该着重提高建筑顶部的气密性并加强内部隔断以降低建筑首层外门处的热压作用;建筑主要出入口应设旋转门或优化门斗的结构以避免冷风直接流入室内.由此针对严寒寒冷地区建筑的冷风侵入问题提出了具体技术对策.
Abstract
There is a strong chimney effect in high-rise buildings in severe cold and cold regions,a large amount of cold air invades when the outer door is opened,which results in low temperature,high wind speed and high energy consumption in the lobby.Based on analysis,calculation,and actual measurement,it was proposed that emphasis should be placed on improving the air tightness of the top of the building and strengthening the internal partition to reduce the thermal pressure effect at the outer door of the first floor of the building.The main entrances and exits of the building should be equipped with rotary doors or the structure of the door bucket should be optimized to avoid direct inflow of cold air into the interior.Specific technical countermeasures were further proposed for the problem of cold wind intrusion in buildings in severe cold and cold regions.
