搭建菲涅尔定向传光装置实验平台，对菲涅尔定向传光装置集热性能进行实验探究，研究菲涅尔定向传光装置抛物反射面焦准距p、反射率ρ、传光距离L、几何聚光比Cg和接收表面吸收率α这5个结构参数及其交互作用对菲涅尔定向传光装置光学效率的相对影响程度，并利用光学软件TracePro对菲涅尔定向传光装置的光学性能进行仿真研究。研究结果表明:焦准距和传光距离这2个因素之间的交互作用对菲涅尔定向传光装置的光学效率具有显著影响，传光距离对菲涅尔定向传光装置的光学效率的影响最显著;正北侧全年平均光学效率最高为81。31%，正南侧全年平均光学效率最高为62。26%。
Study on multi-factor interaction of the orientated light transmitting Fresnel lens solar concentrator
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%.
