Abstract
Energy is a crucial driving factor in today's world and plays major role in economic growth and industrialization. Therefore, there is a great need to explore the renewable energy sources and to develop the renewable energy based technologies. Solar energy is the one of most abundant renewable energy source. The most potential applications of solar energy are drying of agriculture product and heating building. The simplest and the most efficient way to utilize solar energy is by using solar collectors because of their simplicity, cheap and most widely used. Therefore the aim of this work is to study the thermal performance of four configurations of absorber plates of solar air collectors to enhance their performance under three values of air mass flow rates (0.0199, 0.047 and 0.120kg/s) for each type of collector and fabricate an efficient and cheap solar air collector from recyclable aluminum cans.
The results revealed that: 1- The maximum thermal efficiency reached at mass flow rate 0.047kg/s for an solar air collector with an absorber plate made of recyclable aluminum cans )type-I). 2- The highest thermal efficiency was recorded for the solar air collector made of one layer of aluminum cans, whereas the lowest efficiency was obtained for the solar air collector without cans flat plate (type-IV). 3- The thermal efficiency of the solar air collectors depends principally on the solar radiation, surface geometry of the collectors and air mass flow rate.
