摘要: Abstract This paper presents the results of a theoretical and experimental investigation double exposure, flat-plate solar collector with reflective surface. The main role reflector, which is placed below parallel to collector, reflection radiation on lower absorber To enable absorption from surface, it necessary for insulation mounted part box be removed surface replaced by glass cover. In order determine feasibility proposed concept, investigations exposure conventional collectors were carried out. tests verified developed mathematical models thermal behaviour mentioned collectors. advantages collector–reflector system in relation previously investigated are: parallelism between reflector mirror mobility all three possible orthogonal directions. simpler because consists only one reflector. show that performance can significantly higher than collector. experimentally obtained relative difference power these range 41.79–66.44%, highest achieved value this reviewed literature 48%.
