Abstract
In this study an assessment of the influence of the convective heat transfer coefficient on three methods of human body exergy analysis was performed. Four different correlations from the normative of thermal comfort were applied to the exergy analysis. Also, the effect of air velocity on the exergy analysis was analyzed. The results points out that, in general, the response to the change of convective heat transfer correlation presented the same effect at the exergy term related to the convection for all the exergy analysis methods. However, the impact on destroyed exergy rate differs speccially for the method Shukuya et al. (2010). The air velocity effect on the exergy analysis differs considerably for Prek and Butala (2010) exergy analysis method. Also, a good agreement between two of the correlations used to calculate convective heat transfer was observed for all three methods of exergy analysis.
