Abstract:

In this study, the influence of the duct material and insulation on the air heat gain is experimentally investigated. The objective of this study is to present the results of experimental evaluating of the heat gained by the air that flows through a square duct using several materials and insulations. The materials were galvanized steel duct without insulation, galvanized steel duct with 25 mm glass wool insulation and foam duct with a density of 50 kg/m3. Also, for each case, the air flow rate was varied to determine the amount of heat gain. The tabulate data has been drawn by sigma plot software version 10. The results showed that the rate of heat gain in a foam air duct is lower than galvanized iron with insulation and without insulation approximately by 56% and 69%, respectively. In addition, the heat transfer coefficient has a direct proportion with the air flow rate.
