摘要
依据热力学原理实验数据分析了灰尘对太阳能真空管集热性能的影响．研究表明，在雨水充沛地区，雨水会对真空管表面自动冲洗，灰尘对真空管的影响较小，效率会下降10％；在干旱少雨的地区，灰尘对集热管的性能影响比较大，真空管效率会下降40％-50％．
In this paper, through theoretical and experimental data, the impact of the dust on the solar vacuum tube collector performance is analyzed. The research shows that in areas with plenty of rain, rain water will automatically wash the surface of vacuum tube, the impact of the dust is small, efficiency will be decreased by 10%3 in dry areas, the impact of the dust is large, tube efficiency will be decreased by 40% - 50%.
