【摘要】 本文针对南北向水平安置的太阳能槽式系统的光学末端进行了分析和研究,并对太阳能槽式系统的末端损失效应提出了有效优化的方法,且理论计算了该补偿方法的每天和一年光学效率提高率。为了验证该补偿方法的可行性,构建了太阳能槽式系统的实验测试平台,并测试了该实验系统的集热效率,研究发现实验结果与理论计算相符合。文中所做的这些研究工作可为高效率的太阳能槽式系统的设计提供可行性参考。更多还原

【Abstract】 The optical analysis on the end loss effect of parabolic trough solar collector with horizontal north-south axis was performed in this study.The optimized method to compensate its end loss effect was presented.The daily and yearly increased optical efficiency were calculated for the compensation method.In order to verify the feasibility of the compensation method,the experimental system of parabolic trough solar concentrator was built.The thermal efficiency of the experimental system was measured,and the result that the experimental value substantially agreed with the theoretical value.All these works could offer valuable references to the design of high efficiency trough solar concentrator system in the further.更多还原
