摘要
太阳辐射得热是夏季空调负荷的重要组成部分,同时也是冬季采暖负荷的安全系数。因此,合理的遮阳就成为暖通空调领域节能的一个途径。该文以平均遮阳系数作为衡量遮阳效果的指标,以住宅建筑的南窗为研究对象,针对水平遮阳方式,定量分析了我国一些地区水平遮阳板构型尺寸对冬夏季遮阳效果的影响程度。并在综合考虑多方面因素的基础上,给出了这些地区南窗遮阳板构型设计的最佳尺寸。
A quantitative analyses to the prediction of instantaneous irradiance on the shaded fenestration in the south direction during winter and summer was presented. Average shading coefficients in winter and in summer have been selected for evaluating shading effects in different seasons. Considering various factors, optimum configuration of horizontal shading devices in residential buildings of some cities in China was recommended on the basis of different requirements for solar heat gains in winter and in summer.
