摘要：In this paper, the end loss effect of linear Fresnel collector was analyzed. The aim of this work was to investigate the seasonal effects of end losses on the linear Fresnel collectors deployed, and analyze the change of the month average for end loss at different locations. Furthermore, a end loss compensated approach is proposed, and the increased instantaneous thermal efficiency of the experimental system is measured. A two-meter long linear Fresnel collector experimental system with horizontal north-south axis is performed, The result that compensation of the end loss of the linear Fresnel reflector system stands a good improvement for thermal performance. Meanwhile, in comparison with the reflector field prior to the change, an instantaneous thermal efficiency has increased by approximately 50%, and it increased by almost 20% at the afternoon time. All this work can offer some valuable references to the further study on high-efficiency linear Fresnel concentrating system.
