چکیده انگلیسی
Steady state energy balance equations for the finned double-pass solar collector have been developed. These equations were solved using the matrix inversion method. The predicted results were in agreement with the results obtained from the experiments. The predictions and experiments were observed at the mass flow rate ranging between 0.03Â kg/s and 0.1Â kg/s, and solar radiation ranging between 400Â W/m2 and 800Â W/m2. The effects of mass flow rates and solar radiation levels on energy efficiency, exergy efficiency and the improvement potential have been observed. The optimum energy efficiency is approximately 77%, which was observed at the mass flow rate of 0.09Â kg/s. The optical efficiency of the finned double-pass solar collector is approximately 70-80%. The exergy efficiency is approximately 15-28% and improvement potential of 740-1070Â W for a solar radiation of 425-790Â W/m2.
