摘要
选取典型气象年下的10个城市,进行斜面上的太阳辐射日总量平均值进行分析,计算结表明,对于正南安装的集热器,除当地纬度外,散射辐射与总辐射的比率Ra对全年最佳倾角影响显著。以典型气象年太阳能辐射资料为基础,选取我国有代表意义的10个城市,以斜面上的单位面积太阳日辐射总量为目标函数进行计算,得出各典型城市的太阳能集热器的最佳倾角,并分析最佳倾角的变化特点以及最佳倾角的影响因素。
In this paper, the average of total daily solar radiation on the slope of 10 cities with typical meteorological year （TMY） are analyzed, results show that for the due south installed collectors, the ratio of the scattered radiation to the total radiation （Ra） has significant effect on the yearly optimum tilt angle besides the local latitude. Based on the solar radiation data of typical meteorological year, daily solar radiation scale of unit area on the slope are taken as objective function to calculate the optimum angle of solar collector in typical cities and analyze the characteristics of the optimum angle and its influence factors.
