沈阳某高校既有图书馆中庭通风分析优化

OPTIMIZATION OF ATRIUM VENTILATION IN AN EXISTING LIBRARY OF A UNIVERSITY IN SHENYANG

既有建筑由于建造时间较早,运行能耗往往更大,而既有建筑改造不可避免需要尽可能的提高其室内通风效果。文中以沈阳市某高校图书馆为例,在通过实地调研和问卷调查等现状分析的基础上,利用CFD进行模拟优化,并针对天窗可开启面积的大小进行研究。

Existing buildings tend to consume much energy due to the long construction time,the indoor ventilation of which needs to be improved during the renovation process.Taking a university library in Shenyang as the case,the optimization was carried out using a simulation method with computational fluid dynamics(CFD)on the basis of on site investigation and questionnaire analysis.The open area of skylight is also studied.
