In this study, thermodynamic analysis of geothermal energy based multi-generation systems with seven different combinations are performed. The systems considered are mainly examined under two distinct main groups. These groups are applied for heating and cooling periods. In this regard, detailed work flow charts and tables are prepared for each energy system studied. Energy and exergy efficiencies are determined for the entire system and its components and compared for performance assessment. Improvement potentials for every system component and the overall system are calculated and compared. Four performance-related parameters, namely energetic renewability rate, exergetic renewability rate, system energetic re-injection rate and system exergetic re-injection rate are investigated. The analysis results show that overall system energy and exergy efficiency are increased by 3.40 and 1.12 times for cooling season and about 4.25 and 1.25 times for heating season, as compared to the single power generating option.
