采用蒙特卡洛射线追踪法,研究不同季节和安装角度等关键参数对波纹板太阳能集热器与平板太阳能集热器吸热板表面太阳辐照度的影响,并对得到的数据进行分析。模拟结果显示,在相同安装角度下,波纹板太阳能集热器吸热板表面太阳辐照度比平板太阳能集热器大。二者相差的百分比随光线对集热器的入射角而变化,入射角较小时,相差的百分比较大。90°安装时,冬季波纹板太阳能集热器累积辐照度比平板太阳能集热器提升6.2%,夏季二者接近。40°安装时,冬季和夏季波纹板太阳能集热器累积辐照度分别比平板太阳能集热器提升7.1%和6.9%。
Abstract
The Monte Carlo ray tracing method is used to study the influence of key parameters such as different seasons and installation angles on the solar irradiance on the surface of the corrugated plate solar collectors and flat plate solar collectors, and the obtained data are analyzed. The simulation results show that under the same installation angle, the solar irradiance on the surface of the absorbing plate of the corrugated plate collector is greater than that of the flat plate collector. The proportion of difference between the two changes in the incident angle of the light towards the collector. When the incident angle is small, the difference is larger. When installed at 90°, the cumulative irradiance of the corrugated plate collector in winter is 6.2% higher than that of the flat plate collector, and the two are close to each other in summer. When installed at 40°, the cumulative irradiance of corrugated plate collectors in winter is 7.1% higher than that of flat plate collectors, and 6.9% in summer.
