Özet

In this study, energy analysis of a double-stage Organic Rankine Cycle (ORC) was performed using the

Engineering Equation Solver program (EES). In the first and second stages, eight different organic

working fluids (R134a, R410a, RC318, R407c, R22, R23, R116, and R218) were used in pairs for certain

temperature limits. Choosing a suitable refrigerant or refrigerant pair is crucial for the ORC’s high

thermal efficiency and net work output value. This study aims to determine the effect of working fluid on

system efficiency and find out the most suitable working fluid pair. The results showed that the highest

net power output and the highest thermal efficiency were obtained from the R23+R23 pair. It was also

observed that the lowest net power output from the RC318+RC318 pair and the lowest thermal efficiency

was obtained from the R218+R218 pair.
