Study on multi-factor interaction of the orientated light transmitting Fresnel lens solar concentrator
摘要
Abstract
An experimental platform was constructed to investigate the thermal collection performance of the orientated light transmitting Fresnel lens solar concentrator.The relative influences of five structural parameters(i.e.,the focal distance of the parabolic reflective surface(p),the reflectance(ρ),the light transmission distance(L),the geometric concentrating ratio(Cg)and the absorption of the receiving surface(α))and their interaction on optical efficiency of the orientated light transmitting Fresnel lens solar concentrator were examined.The optical software TracePro was used to simulate the optical performance of the orientated light transmitting Fresnel lens solar concentrator.The results show that the interaction between focal length and light transmission distance has significant impact on the optical efficiency of the oriented light transmitting Fresnel lens solar concentrator,while the light transmission distance has the most significant impact on the optical efficiency of the oriented light transmitting Fresnel lens solar concentrator.The highest annual average optical efficiency on the north side is 81.31%,while the highest annual average optical efficiency on the south side is 62.26%.关键词
