Thermodynamic properties of HFO-1243zf and their application in study on a refrigeration cycle

Thermodynamic properties of HydroFluoro-Olefin, 3,3,3-trifluoropropene (HFO-1243zf) are firstly modeled with an accurate molecular based PC-SAFT equation of state (EOS). The average absolute deviations (AAD) between vapor pressures, saturated liquid densities from this developed PC-SAFT EOS and experimental data are 0.15% and 0.80%, respectively. The average absolute deviations between predicted gaseous pressures, sub-cooled liquid densities from the PC-SAFT EOS and experimental data are 0.91% and 0.92%, respectively. In this study, the developed PC-SAFT EOS for HFO-1243zf and other EOSs for R-134a, R22, and R32 are used in the investigation of a refrigeration cycle for air conditioning application. The results show that cycle using R1243zf as refrigerant has the highest coefficient of performance (COP) and it is a potential candidate for the replacement of R134a in a refrigeration cycle. •All thermodynamic properties of 3,3,3-trifluoropropene (HFO-1243zf) are available.•Accurate PC-SAFT equation of state for HFO-1243zf is firstly modeled.•Uncertainties of vapor pressure and saturated liquid density are 0.15% and 0.80%.•COP of cycle using HFO-1243zf is higher than that of cycle using R134a, R22, R32.
