ABSTRACT In this study, thermodynamic analysis of a geothermal power-based district energy conversion system which produces electricity, hot water, heating and cooling are investigated. The energy produced from geothermal resource can be utilized to drive a double stage organic Rankine cycle (DS-ORC) and a single effect absorption cooling (SEAC) system. Integrated system analysis is conducted by using the Engineering Equation Solver (EES) software program. The energy and exergy efficiencies of integrated system and its two sub-systems (DS-ORC and SEAC) are calculated. Also, a parametric study is given in order to find out how different operating conditions effect the integrated system and its sub-systems performance. As a result, it is observed that overall energy and exergy efficiencies of whole system are 38.28% and 36.39%, respectively
