摘要: 腔体是超高层建筑塔楼的外向型公共空间,不同腔体的布局和尺度差异会影响建筑的室内风环境. 文中研究了腔体在过渡季节通过烟囱效应的拔风作用对室内自然通
风状况进行改善的可能; 通过选取广州地区南向接触式腔体为研究对象,建立简化的概念模型,借助特定的风环境模拟软件对室内风速、PMV-PPD( 预计平均热感觉指数和预计不满意者百分数) 进行计算分析. 结果显示,通过设置合理的腔体高度、腔体进出风口大小及位置,可以使大多数楼层在过渡季节获得稳定的自然通风,并使室内热环境处于人体舒适范围内.

Abstract: Chambers are the outward atrium spaces of super high-rise buildings.The location and size of different chambers may influence building's internal ventilation.This paper discusses the possibility of improving the natural ventilation inside super high-rise buildings by using the stack effect of chambers in the transitional seasons.By taking the southward contact-style chambers in Guangzhou region for samples,a simplified concept model is constructed,and the internal wind velocity as well as the PMV-PPD ( Predicted Mean Vote and Predicted Percentage of Dissatisfied) values is calculated and analyzed with the help of typical ventilation simulation software.The results indicate that,by setting reasonable chamber height and by adjusting the location and size of chamber s inlet and outlet,most buildings may encounter natural ventilation stably in the transitional seasons,and the internal thermal environment can be maintained within a comfort range for human beings.
