摘要

In this study, different coating samples of antimony tin oxide (ATO) films on clear glass were prepared and their optical and thermal properties were evaluated. Performance parameters such as glass U-factor, solar heat gain coefficient, temperature distribution, and net heat transfer gain using the glazed walls inside the test room were determined through numerical simulations. The results obtained indicate that the nanocoating thickness and doping level concentration of ATO films have a pronounced effect on the thermal insulation of the window glass. When compared with normal window clear glass, the transmittance of solar radiation for ATO thin-film coating of thickness 1140 nm reduced from 0.881 to 0.114 in the visible (VIS) region and 0.817 to 0.012 in the infrared (IR) region, whereas radiation in the ultraviolet (UV) region was almost completely blocked. Similarly, for the ATO films with doping level 15%, the transmittance value reduced from 0.742 to 0.432 in the VIS region and from 0.718 to 0.114 in the IR region, and radiation in the UV region was almost totally blocked. Finally from the analysis of results, it was observed that the ATO thin films show exceptional optical and thermal properties and exhibit improved solar blocking behavior when compared with commercially available glazing (eg, from Saudi Arabian glass companies).
