Investigation of Exergetic Efficiency and Thermodynamic Parameters of the Salihli Geothermal District Heating System

This study investigates thermodynamic parameters and exergetic efficiency of the Salihli geothermal district heating system (SGDHS) in Manisa, Turkey for 2005/2006 heating season. The thermodynamic parameters considered are as follows: (i) fuel depletion rate, (ii) relative irreversibility, (iii) productivity lack, and (iv) exergetic factor. These parameters are determined for the system to assess and compare their individual performances. While the highest relative irreversibilities occur in the heat exchangers with the values of 44% for the SGDHS, exergetic efficiency of the system is found to be 60.3%.
