摘要
以卡斯特洛夫公式为理论基础,得到各朝向墙面可能晴天太阳总辐射和直接辐射小时总量的计算方案,计算了我国704个气象站各月代表日各个朝向墙面的逐时辐射值,分析其变化规律,并讨论了最大1 h辐射量的全国分布。结果表明:南墙晴天最大1 h辐射量随纬度升高而增大,而且在冬季其辐射量在各墙面中最大;东、西墙受纬度因素影响相对较小,在夏季其辐射量在各墙面中最大。
Based on the kastrov expression, the calculative method of the possible sunny day total and direct radiation received by wall surfaces with different orientations was obtained. Using vapor pressure to fit the parameter of expressions, we calculated the hourly solar radiation amount received by wall surfaces with different orientations at 704 stations of China, and analyzed its variations. The distribution of radiation exposure in the strongest hourly radiation over China was also analyzed. Results show that the sunny day solar radiation amount received by southern walls increases with latitude in winter and it is the largest among those recieved by walls with different orientations; and variations of the sunny day solar radiation received by eastern and western walls with latitude are relatively smaller than other orientations and its radiation amount is the largest in summer.
