With the increased attention the efficiency of solar heating facilities and the performance of additional equipment are becoming increasingly important. In the present study, thinking is giving on the heat transfer characteristics of solar air heater with some modifications in design to increase air travel length. Performance of solar air dryer would be checked with and without air heater. Effect of climate conditions would also be studied on its performance. Keywords:Solar Air Heater, Air Heater, Heat transfer, Solar Collector, Solar Energy
