Impact of the partial absorption of solar radiation in translucent covers of the flat-plate solar collector housing on the heat losses of their light-absorbing heat-exchange panel into the ambient

Abstract

This article presents the results of the design studies intended to determine the impact of partial absorption and conversion to heat of solar radiation (SR) that penetrates translucent covers (TCs) of the housing of flat-plate solar collectors (FSCs) for heat transfer fluid (HTF) heating. These studies have served as the foundation for deriving the equation to find the value of the reduced effective coefficient of the heat losses into the ambient from the light-absorbing heat-exchange panel (LAHP) of the collector in question.
