Thermal Performance of a Double-pass Solar Air Heater

This study analyzes the thermal performance of solar thermal energy using double-pass absorber plate in Sanandaj, Iran. To this end, a mathematical model was encoded according to the energy and exergy balance equations and solved by MATLAB software. Given the environmental conditions and radiation intensity of a winter day in Sanandaj, the effects of external parameters such as radiation intens...

Effect of depth ratio on the thermal performance of double flow packed bed solar air heater

In this paper double flow packed bed solar air heater has been investigated theoretically. The effect of air mass flow rate, porosity and different depth ratios at study state conditions on the thermal performance of a double flow packed bed solar air heater is found by using the alternative simulation system. Comparisons between the measured thermal and effective thermal efficiency of the doub...
