| Abstract | ||
| In this paper, an experimental study of the thermal performance of the solar air collector manufactured of galvanized iron sheet with dimension 100×120cm, frame width 20cm, has holes 0.5cm arrangement on horizontal and vertical, the collector inclined at an angle (75o) on the horizontal plane. All author faces of the collector (four sides and background) are insulations in order to minimize the thermal losses .All the result recorded in winter season for two different days one of them sunny and the other was cloudy. The result shows the effect of the angle of collector gives more heat to the collector, hence higher outlet temperature, especially in sunny day. Maximum outlet temperature of the collector (35.5o when inlet temperature 18o) and maximum Nusselt number(Nu) at twelve o’clock of the sunny day more than the cloudy day. At the end its high system efficiency and good collector effectiveness. | ||
