The Efficiency of New Solar Flat-Plate Collector
Aerogel is a highly porous material. It has the best thermal insulation properties in all solid-state materials. This paper carried out a preliminary study to see the influence on efficiency of flat-plate collector used aerogel. Keeping the other parts of flat-plate collector unchange, the aerogel layer is placed between the transparent cover and absorber plate. Through specific calculation, analysed thermal efficiency of this model of flat-plate collector, and compared with the ordinary glass model. The results show that aerogel can greatly improve collector efficiency , as table 1 show the efficiency of aerogel model is 1.66 times higher than ordinary model.
