Summary: The low performance of geothermal power generation system is mainly caused by the poor performance of its components, especially the turbine. By increasing the isentropic efficiency of the turbines and the working fluid pumps, and decreasing the heat transfer temperature difference of the evaporator and the condenser, the internal exergy destruction of each component can be reduced, thereby improving the system performance.

Summary: Considerable interest has been shown in the investigation of energy supply systems that effectively utilize renewable energies, and geothermal energy has been considered a promising alternative to fossil energy. This paper developed a geothermal-driven tri-generation system to generate power and supply heating and cooling demand. The effects of geothermal water parameters on system performance were investigated based on actual data, and a multi-objective optimization was conducted considering economic and environmental criteria. The results indicated an optimal geothermal water temperature of 83 degrees C, with high thermal and exergy efficiencies. The proposed system had an equivalent annual operating cost of 12.9 k$/year, with a payback period of 2.57 years and carbon emission reduction of 2379 ton/year.
