An investigation on organic Rankine cycle incorporating a ground-cooled condenser: Working fluid selection and regeneration

This research presents an optimization of a power generation system incorporating ground-cooled condenser. It focuses on the mitigation adverse effects critical parameters such as low mass flow rates and large ground loops. includes investigation different configurations (basic regenerative cycles) working fluids to ascertain their performance system. Three refrigerants, R123, R124 R245fa, were compared in terms fluid's performance. The purpose is increase net output whilst reducing capital cost installation. At inlet expander pressure 3 MPa, condensation temperature was decreased from 25 °C 15 enhancements 7.35%, 12.13% 8.77% for respectively case basic organic Rankine cycle. However, highest recorded R123 both under investigated conditions. Based calculations heat rejection, cycle highly recommended since it provides significant without considerably changing amount rejected ground.
