EXPERIMENTAL STUDY & PERFORMANCE ANALYSIS OF SOLAR AIR HEATER

Solar air collector is a specific type of heat exchanger that transfers heat to air, which is obtained from absorbing solar radiation by absorber. In solar air collector heat transfer occurs from an energy source which spreads radiation to the air. It consists of an absorber plate, supportive walls, ducts or channels of fluid flow, glazing, air blower or fans (if forced convection), and insulation to minimize heat losses. Almost parts of solar air collector or heaters are thermally well insulated to reduce thermal heat losses.
