基于自然通风的长沙高校图书馆中庭形态研究

Research on atrium form of Changsha university libraries based on natural ventilation

为研究图书馆中庭形态对自然通风的影响,通过对长沙地区的高校图书馆进行实地调研,系统分析该地区高校图书馆自然通风特点和问题,以图式提取该地区高校图书馆中庭基本原型,并根据调研所得图书馆基本数据,建立基础物理模型.采用Phoenics软件,在考虑太阳辐射和室内外热环境的情况下,对不同中庭方位、数量以及剖面形式的图书馆原型进行参数模拟.结合自然通风理论,对比数据分析所得结果,最终从中庭布局方位、中庭数量和中庭剖面形式三个方面,提出有利于长沙地区高校图书馆自然通风的中庭空间形态,为该地区高校图书馆被动低能耗设计提供参考.

In order to study the influence of library atrium form on natural ventilation,through the field research of university libraries in Changsha area,systematically analyzed are the characteristics and problems of natural ventilation of university libraries in the area,and the basic prototype of university library atrium in the region is extracted.Based on the major data of the library obtained from the survey,a basic physical model is established.Using Phoenics software,considering the solar radiation and the indoor and outdoor thermal environment,the parameters of the library prototypes of different atrium orientations,numbers and profiles are simulated.Combined with the natural ventilation theory,the results of the data analysis are compared,and finally the orientation from the atrium is In the three aspects of the number of atriums and the atrium profile,this paper proposes a space shape that is conducive to the natural ventilation of university libraries in Changsha,and provides a reference for the passive low energy design of university libraries in the region.
