摘要: 广州墙面日照时间的时空分布某方位倾斜面每日可照时间Tot由下式计算:Tot=(ωss-ω(sr))/15 (1)式中ω(sr)和ωss为倾斜面的日出、日没时角,以度为单位。在不考虑地形和地物遮蔽情况下,联合比较倾斜面的两个临界时角(h1和h2)以及水平面日没时角(ω3),则可确定ω(sr)和ωss。总的确定原则是:要求从ω(sr)到ωss(顺时针方向)的时角范围内,太阳既要在地平线以上,又要在倾斜面的前面。当偏北朝向倾斜面夏半年出现两段可照时间时,要分别计算,然后相加。

Abstract: The aim of This paper is to reveal the temporal and special distribution features of sunshine duration and solar radiatioil on vertical and particular tilted surfaces in Guang zhou.The daily,monthly and yearly possible sunshine duration the extraterrestrial solar radiation incident upon vertical surfaces of various of various in Guangzhou are computed and analyzed.Based on the values of Rb,computed by means of the anisotropic diffuse radiation model proposed by Hay,the author studies the azimuthal and seasonal distribution futures of the direct and global solar radiation on vertical surfaces in the city.For the purpose of solar energy utilization for flat-plate collectors,the optimum tilted surfaces:and the relevant global radiations on the surfaces in Guangzhou are ascertained.
