Effect of load variations on exergy performance of solar box type cooker
In recent times, performing the exergy based analysis on solar cookers has gained momentum. It has been observed that the variations in exergy output power and exergy power lost with temperature difference are qualitatively similar in nature for various topological designs of solar cookers. In the present manuscript, variations in the exergy power output and exergy power lost with temperature difference for different loads/mass of water have been reported for solar box type cooker. The four different benchmark parameters, viz., heat loss coefficient, quality factor, peak exergy, and exergy temperature difference gap product are determined for each case. The mutual dependence of these parameters and the conceptual understanding of their variations with different load of water are explained. The adjusted value of the quality factor has been found to be independent of the mass of water kept inside the cooker during full load tests. The findings also confirm the earlier reports in terms of qualitative response and strengthen the case of exergy based test protocol for solar cookers.
