Multicriteria study of geothermal trigeneration systems with configurations of hybrid vapor compression refrigeration and Kalina cycles for sport arena application

Among the famous renewable energy sources all around the world, geothermal heat is known to be accessed plentifully. The present paper investigates three geothermal cycles in the viewpoint of the first and second laws of thermodynamics, exergoeconomic, and exergoenvironmental analysis. The provided cycles, A, B, and C are trigeneration cycles with power, cooling load, and domestic hot water as products. The final system is theoretically customized to sustain a sport facilitation. The proposed cycles were simulated by EES software and validated by reliable references. The investigations demonstrate that considering thermodynamics' first and second law, cycle C has the best performance compared to cycles A and B with acceptable functionality on an exergoeconomic standpoint. For cycle C, energy efficiency, exergy efficiency, and net output power were calculated as 69.75 %, 29.79 %, and 68.8 kW, respectively. The exergoeconomic analysis of cycle C revealed the cost of product and exergy destruction as 160.4$/GJ and 150.45 kW, respectively. An exergoenvironmental study was compiled to study the effects of the system on the environment with respect to associated environmental parameters. A 3D multi-objective optimization was performed to identify the optimal condition with respect to target parameters. The purpose of the current system is to sustain a sport arena.
