TL;DR: In this article, the effect of absorber plate material on the efficiency of heat-absorbing flat plate collectors was investigated, which indicated that aluminum is a better absorber of heat than copper.
Abstract: The study was conducted to investigate the effect of absorber plate material on the efficiency of heat-absorbing flat plate collectors Aluminum and copper used in this study because of the heat transfer ability of both materials is high Absorber plate thicknesses used were 1 millimeter and 2 millimeters which is suitable for the conduction of heat to the working fluid A model was designed for the experiment The model was horizontal to the ground during the experiment which conducted from 1000H to 1700H Inlet and outlet temperature were tabulated into a table with a fix fluid flow rate Based on the results of the study, 2 millimeters thick aluminum absorber of heat is suitable for use in solar energy collectors This indicates that aluminum absorber plate is a better absorber of heat in the context of this study Aluminum is capable of absorbing heat and store heat longer than copper and contributes to high efficiency of the flat plate collector

TL;DR: In this article, the authors developed a general procedure for calculating the net energy flux through the glazed area of a window composed of an arbitrary number of solid layers, which can have any specified solar and thermal radiation properties and enclosed spaces between solid layers can contain either air or other gases.
Abstract: To calculate the energy performance of buildings, one must know the heat-transfer characteristics of the windows as functions of environmental variables, such as temperature and wind speed. Window designs are becoming more complex in response to the need for energy conservation. In this paper, we develop a general procedure for calculating the net energy flux through the glazed area of a window composed of an arbitrary number of solid layers. These layers, which may have thin-film coatings, can have any specified solar and thermal radiation properties and enclosed spaces between solid layers can contain either air or other gases. We verified our results by comparing them with experimental measurements of heat flow using a calibrated hot-box.
