|Solar collector with transparent insulation 255 kB|
The possibilities of transparent thermal insulations use in solar collecors are described. Author compares energy savings of different types of transparent insulations used on collectors produced by Czech firm EKOSOLARIS a.s.. Computer programmes KOLEKTOR and PROVOZ_SK are used for all-year energy savings evaluation. These programmes are based on Reference Year Climate Data for Prague region and were corrected according to real measured results in open Solar Laboratory at Department of Environmental Engineering, CTU Prague. The results confirmthat transparent insulation of honeycomb structure applied at usual non-selective absorber is rather more efficient than single-glazed higly selective absorber.
