International Journal of Exergy (IJEX), Vol. 8, No. 1, 2011

Abstract: In this study, three new exergy parameters, namely total exergy destruction ratio, component exergy destruction ratio and dimensionless exergy destruction are introduced in addition to energetic renewability ratio, exergetic renewability ratio, energetic reinjection ratio and exergetic reinjection ratio, and compared for Edremit and Bigadic Geothermal District Heating Systems (GDHSs) based on their actual data. The respective daily graphs of these parameters are presented. Also, regression analyses using the actual data are performed to obtain some correlations for practical use. In brief, these parameters help us to identify the degree of renewability and other aspects and provide some insights.
