摘要
以住宅的围护结构、朝向和当地气候的特点为研究对象,选取南、北朝向不同窗墙比的围护结构进行传热分析,建立了不同窗墙比的围护结构传热模型,计算出南北朝向的逐时热流密度值,并作为计算窗户传热的边界条件,利用FLUENT软件对进行数值模拟。模拟结果表明随着窗墙比的增加,围护结构传热量迅速上升。
By taking the enclosure structure and orientation of housing and characteristics of local climate as the research object,the heat transfer analysis on the different window-wall ratios of enclosure structure in southern and northern orientation are studied.With different window-wall ratios,the heat transfer model of enclosure structure is established,which can calculate hourly heat flux value as boundary conditions of calculating window heat transfer.The heat transfer model is simulated using FLUENT software.The results show that heat transfer quantity of enclosure structure increased rapidly with increasing window-wall ratio.
