利用MATLAB优化太阳能平板集热器安装倾角

Optimization of Plate Solar Collector Installation Angle with MATLAB

太阳能平板集热器是太阳能热利用领域用得最普遍的部件之一,集热器表面上所能接收到的太阳能不仅与地理位置、季节等有关,还与集热器的安装倾角直接有关。在建立太阳辐照模型的基础上,以宁夏银川地区为例,利用MATLAB仿真软件模拟计算了一年中每月的平均日下,集热器表面上接受到的全天总辐照量;以全天总辐照量为考察指标,对集热器的安装倾角进行了优化分析,为太阳能的开发利用提供理论借鉴。

Plate solar collector is one of the most common components in solar energy heat utilization field. The solar energy received by the solar collector surface is not only related to geographical location, season, etc, but also related to the instal- lation angle of the collector. In this paper the solar irradiation model was presented and the daily total irradiance received by the surface of the collector was calculated at the monthly average day in one year with the example of Yinchuan in Ningxia area. With the examining index of round-the-clock total irradiance, the installation angle of the collector was optimized which provides theoretical reference for the development and utilization of solar energy.
