主 题:solar energy concentrated solar power linear Fresnel reflector greenhouse thermal and optical analysis experimentation
摘 要:Concentrating solar power technology is one of the most promising alternative energy *** recent past,Linear Fresnel Reflector systems have received great attention and novel designs have been proposed keeping in view the objective to enhance its functionality and *** achieving the same objective,this study presents a novel concept where a conventional LFR is enclosed in a greenhouse called *** was expected that such an enclosure can:(1)increase the incoming solar radiation,(2)further improve the overall efficiency due to simplified cleaning process and(3)reduce the capital cost for the construction of LFR support system.A complete thermal and optical analysis was presented for modeling and performance evaluation of the solar field of both conventional-LFR and novel *** of non-linear equations for each system were solved using Newton-Raphson *** detailed optical analysis was further performed for conventional-LFR considering the seasonal *** results concluded that the greenhouse-LFR is better than the conventional-LFR as it had higher efficiency and useful heat with lesser heat *** greenhouse-LFR,the maximum thermal efficiency was 73.2%whereas for conventional-LFR it was 37.2%.Also,there was an average increase of useful heat by 3 times in the month of February and 4.7 times in the month of ***^(TM) analysis indicated significant spillage loss when a conventional-LFR was used without a secondary reflector or slight curvature of the mirrors.
