Energy, Exergy, Exergoeconomic, and Exergoenvironmental Assessment of Flash-Binary Geothermal Combined Cooling, Heating and Power Cycle

This research presents the energy, exergy, economic, and environmental assessment, multi-objective optimization of a flash-binary geothermal CCHP cycle. A sensitivity analysis production well inlet temperature cooling to power flow ratio on exergetic, parameters was conducted. Furthermore, effects inflation rate plant working hours economic were investigated. Results showed that increasing harms exergy efficiency exergetic performance criteria results in gain exergo-environmental impact index heating capacity. In addition, total cost increased by raising temperature. caused reduction efficiency, criteria, produced net an enhancement destruction, capacity, cost. The base case 58% 0.1764, respectively. Optimization at selected optimum point, 4.5% higher, 10.3% lower than case. Levelized energy pay-back period point obtained as 6.22 c$/kWh, 3.43 years, which 5.14% 6.7%
