Thermal Analysis of a Solar Air Heater Integrated With Finned Absorber Plate

Abstract

In the given analysis, the exergetic analysis of finned absorber plate solar air heater (SAH) is done. Here Thermal model for finned based absorber plate SAH is developed. Experimental observations were made in Indian (25º N, 81º E) climatic circumstances. About 9.87% deviation is observed in theoretical & experimental values of exit air temperature of SAH. Highest value 2.17 % exergy efficiency could be accomplished here. The obtained results show the improvement in the solar air heater performance.
