Evaluation of Geothermal Energy Resources in Terms of Exergy Analysis
Energy is recognized as a crucial element in a country development process. Geothermal resources are a green energy source that can make a considerable contribution in some countries. Also efficient use of resources is important due to availability, economic and environmental issues and comprises the essence of this work. The exergy analysis is a powerful tool for the design, analysis and classification of thermal systems. Using exergy for resource classification benefits their comparison, according to their ability to do work. Specific exergy index (SExI) was calculated to show for classification and capability of some geothermal area. Actual system data are used to assess the district heating system and power plant performance, energy and exergy efficiencies. In this study, specific exergy index for examined field was calculated between 0.026 and 0.947 and sustainability index (SI) was found between 1.420 and 2.782.
