摘要:
针对呼和浩特地区的槽式太阳能聚光集热系统能流分布的影响因素进行分析,利用降维计算方法分析了吸热管壁面能流密度分布的影响因素,搭建槽式太阳能集热器焦面能流密度分布测量装置,对集热器聚焦区域能流密度分布进行测量。结果表明:不同太阳入射角θ所对应的吸热管壁面能流密度分布及峰值大小均不同,随系统跟踪偏差的增大,壁面能流密度分布趋势呈现错位形态分布;根据测试得到集热管能流分布的灰度和彩虹图,分析集热系统焦面能流分布规律及各项偏差因素对能流密度测试的影响,以及该能流密度分布测量系统主要测量不确定度,得到该系统相对标准不确定度为5.39%。
Abstract:
This paper analyzes the influencing factors of energy flow distribution of the trough concentrator collector system in Hohhot, and that of flux density distribution of the heat absorbing pipe wall by the dimensionality reduction calculation method. A focal plane’s energy flow density distribution measuring device was built for trough solar collectors to measure the energy flow density distribution in the focal region of the collector. The results showed that various solar incident angles θ corresponded to different flux density distribution and peak value of the heat absorbing pipe wall. With the increase of system tracking deviation, the flux density distribution of wall appeared a tendency of dislocated distribution; the grey-scale map and rainbow graph of the flux density distribution in heat collecting pipe were obtained from the measurement experiments, then on the basis of this, we analyzed the influence of the focal plane’s energy flow density distribution law and various deviation factors of the system, as well as the main measurement uncertainty of this flux density distribution measurement, deriving that the relative standard uncertainty of the system was 5.39%.
