Analysis of Selective Absorber Coatings on Thermal Performance of the Solar Flat-Plate Collector

Abstract:

In this work, a solar flat-plate collector test system is developed. The solar flat-plate collectors with anodic coating, chromium coating and blue core coating are tested. The experimental results indicate that the relative absorption ration α/ε of blue core coating is up to 19. The efficiency of collector with blue core coating is 78.66%, which is 5% higher than collectors with the other two types of coatings. In addition, collector with blue core coating has smaller total thermal loss coefficient. The blue core coating can effectively improve the performance of solar flat-plate collectors.
