不同月份及不同安装角度时平板太阳能集热器接收的太阳辐照量分析

通过理论计算模型推算出在山东省济南市不同月份及不同安装角度时平板太阳能集热器接收的太阳辐照量理论数据,并与实际测量数据进行对比。结果表明:理论数据与实测数据存在高度的一致性;与安装角度为75°时相比,安装角度为90°时平板太阳能集热器接收的太阳辐照量有所下降;通过对全年不同安装角度下平板太阳能集热器接收的太阳辐照量实测值进行对比发现,5~8月时的差异最为明显,1~3月、11~12月时的差异最小。该研究结论可为不同月份时选择平板太阳能集热器的最佳安装角度提供理论依据和参考。

ANALYSIS OF SOLAR IRRADIATION RECEIVED BY FLAT PLATE SOLAR COLLECTOR IN DIFFERENT MONTHS AND AT DIFFERENT INSTALLATION ANGLES

In this paper,the theoretical calculation model is used to calculate the solar irradiation value received by the flat plate solar collector in different months and at different installation angles in Jinan City,Shandong Province,and compared with the measured values.The results show that:there is a high consistency between the theoretical value and the measured value;compared with the installation angle of 75°,the solar irradiation received by the flat plate solar collector at the installation angle of 90°decreases.The comparison results of measured value of the solar irradiation under different installation angles show that the difference is bigger from May to Auguest and smaller from January to March and from November to December.The results of this research can provide a theoretical basis and reference for choosing the best installation angle of flat plate solar collectors in different months.
