[Abstract]:Taking the net work and irreversible energy loss of the system as the target parameters, a multi-objective function optimization system for marine thermo-energy ORC system is established. The effects of evaporation temperature, condensation temperature, working fluid flow rate and outlet temperature on the performance of the system are studied. The results show that the system performance is optimal with the existence of optimal parameters, the higher the condensation temperature, the higher the evaporation temperature, the greater the target value of the system and the worse the system performance, and the lowest energy consumption of R227ea is the highest among the six working fluids selected in this paper. The optimum effluent temperature of warm seawater is 1920 鈩，
