dc.description.abstractAn exploratory study is presented considering the effect of eight different binary mixtures that serve as working fluid for a transcritical Rankine cycle operating with or without recuperator – the binary mixtures considered are composed by CO2, a natural fluid, and a secondary fluid (i.e., R134a, R32, R152a, R41, R161, R1234ze(E), R1234yf, R1270). The secondary component selection was based on its environmental impact (i.e., GWP < 1500 and ODP = 0) and glide temperature (< 40 ºC). In addition to the working fluid composition, the study also addressed the effect of the mixture’s mass fraction, which ranged from nearly pure refrigerant to nearly pure CO2, turbine inlet pressure and the heat source’s temperature on the thermal performance of the cycle. The results obtained show that, while mixtures with large mass fractions of refrigerant tend to thermodynamically outperform nearly pure CO2 mixtures, compositions with high CO2 content are capable of delivering competitive performance levels when technical and environmental parameters of the power plant and working fluid are considered.en_US
