Thermal Performance of Mixed Asphalt Solar Water Heater
Abstract
This paper deals to investigate the thermal performance of the mixed asphalt solar water heater. The mixed asphalt solar water heater composes of mixed as asphalt as an absorber plate, copper tube, glass cover, and insulation material. The mixed asphalt solar water heater area is 0.5 m2, and always constant feed water at 0.02 kg/s. The air gap between glass cover and absorber plate is 0.004 m, and inclination angle was fixed at 30°. The copper tube of length 9 m with 0.135 m2, cross-section area. The experimental set-up was located at latitude 13°47'41.3"N, and the longitude 100°17'56.7"E Thailand. The experimental data were used to assess thermal performance, based on the following parameters such as the absorbers surface temperature, the temperature difference between inlet and outlet water temperature, useful energy, and energy efficiency. The result shows that the maximum absorber plate temperature and the temperature difference between the inlet and outlet water temperature are obtained to 60°C and 17.2 °C respectively. While, the feed water has been obtained amount of heat in the range 100-380 W/m2. As above results is found to range 70-79%.
