Özet

In this study, a multigenerational hybrid system, which is consisting solar, geotermal and Organic Rankine Cycle (ORC) with working fluids R245fa, R245ca and the new generation fluid R1233zd, was simulated via a simulation software. After simulations, the results were analyzed and compared. According to these results, the highest system thermal efficiency value as 0,158 was gained with the R245fa working fluid. Then, the system thermal efficiency with R1233zd is 0,15, and lastly the lowest thermal efficiency is 0,14 with R245ca, respectively, under similar working conditions of the multigenerational system. However, the biggest generator work is supplied with R1233zd as 99,403 kW, then with R245ca as 68,958 kW, then with R245fa the lowest generator work value as 27,526 kW. Accordingly, as a result, R1233zd, and then R245fa supplied the best performance values for this ORC system, respectively. Further future studies on this subject area is on spot and continuing.
