摘要
在对常用典型气象年的构成以及上海地区太阳辐射资源的分析基础上,利用Ecotect软件模拟了不同方位角和倾角下斜面接收太阳辐射的变化,并对太阳能集热装置安装方位角和倾角进行了最优化研究。研究表明:以最大年辐射总量为指标,上海地区太阳能集热装置最佳位置为方位角30°,倾角26°。计算结果与两组实验值对比表明,最大相对误差为3.8%。本文计算结果可为实际工程中太阳能集热装置的安装布置提供参考。
Solar radiation with different azimuth angle and obliquity in shanghai was researched by ECOTECT. The optimum azimuth angle and obliquity for the solar energy gather equipment were also conducted based on the composing of typical weather year and the solar resource of Shanghai. The optimum location of solar gather equipment in Shanghai was gotten and the maximum relative error was less than 4 %. The resalts it can be used in the setting of the solar equipment in practical project.
