Abstract


Solar energy is an economical alternative to the today’s energy demand. Solar air heater is used for heating the air economically but produces low thermal efficiency. In this study, an attempt has been made to increase the thermal efficiency of solar air heater by using iron scraps as absorber to enhance the heat transfer, thereby increasing the efficiency. The matrix solar air heater with iron scraps as absorber produces higher thermal efficiency over the conventional flat plate solar air heater.


Keywords
