摘要
介绍了带遮阳百叶的通风玻璃幕墙的“透射体系模型”、“传热模型”、“热阻模型”。列出系统的热平衡方程,求解了太阳辐射改变时通道内的传热系数的变化情况。计算机模拟表明: 在夏季,通风玻璃幕墙的透射率较普通幕墙有显著降低,传热系数也比中空玻璃和无遮阳百叶的通风幕墙有显著减小。
Heat transfer equations were set up to determine the convection and radiation transfer coefficient equations were solved using a matrix-inversion solution procedure. Introduced ＂fenestration model transferring model＂, ＂thermal resistance model＂of double skin facade. Satisfactory data were obtained and results indicate in summer double skin facades could cut down the temperature of curtain wall cover and lower gaining load by way of solar radiation.
