In this study, modeling, optimization and economic analysis of a multiple generation system based on the use of solar energy using thermoelectric in the Rankin organic cycle. The system under study consists of solar panel subsystems, Rankin organic cycle, absorption chiller and PEM electrolyzer. The fluid used in the Rankin organic cycle contains refrigerant R123. Thermodynamic software for solving EES engineering equations has been used to model the studied system and also to obtain the results of system analysis. In this study, a comparison was made between two systems with the presence of thermoelectric and the system without the presence of thermoelectric and the use of condenser in the Rankin organic cycle and according to the results, the system with thermoelectric presence has better performance. According to the studies performed on the parameters affecting the system outputs, we can name the inlet temperature to the turbine and the area of the solar panel. According to the system exergy degradation study, the solar panel has the most exergy degradation and the least exergy degradation is related to the pump. The NSGA-II genetic multi-objective algorithm is used to optimize the objective functions of the designed system. The two opposite objective functions studied in this study were to increase exergy efficiency and reduce cost rate. The Pareto diagram was obtained in order to determine the best values for the objective functions of the problem, which are the system exergy efficiency and the system cost rate. Finally, the optimum value of the exergy efficiency was 18.25% and the cost rate was $ 1.87 per hour. Also for case study in this study, Khuzestan province and Dezful, Ahvaz and Abadan cities were selected. The results of a case study showed that this system has a high performance in Khuzestan province and the best results were obtained in Abadan. |
