Influence of Ambient Temperature, Wind Speed, Emissivity, and Average Working Temperature of Light-Absorbing Heat-Exchange Panels of Flat-Plate Solar Water-Heating Collectors on Their Thermal Losses Through Translucent Coatings

Abstract

This article presents the results of computational experiments aimed at determining the influence of the ambient temperature (\({{t}_{a}}\)), wind speed (v), average working temperature (\({{\bar {t}}_{{avw}}}\)), and emissivity of light-absorbing heat-exchange panels (LAHPs) \(\left( {{{\varepsilon }_{p}}} \right)\) on their thermal losses through the translucent coating (TC) of the case of flat-plate solar water heating collectors (FSWHC) with a single-layer TC.
