Özet

This article presents the importance and usefulness of Second Law (exergy) analysis for evaluating and comparing solar cookers in meaningful ways. The thermodynamic considerations required for the development of rational and meaningful methodologies for the evaluation and comparison of the efficiency of the solar cookers were defined. Energy and exergy equations were also developed to obtain energy and exergy efficiencies of the solar cookers. The evaluation of the solar cookers requires a measure of efficiency, which is rational, meaningful, and practical. Exergy analysis provides an alternative means of evaluating and comparing the solar cookers. Since exergy is a measure of the quality or usefulness of energy, exergy efficiency measures are more significant than energy efficiency measures, exergy analysis should be considered in the evaluation of the solar cookers.
