Fluoropropenes such as R-1234yf or R-1234ze(E) have attracted attention as low GWP (global warming potential) refrigerants, both as pure compounds but also to an increasing extent as components in refrigerant blends. In our earlier work [Raabe, G.; Maginn, E. J. J. Phys. Chem. B 2010, 114, 10133-10142 and Raabe, G. J. Phys. Chem. B 2012, 116, 5744-5751], we have introduced a transferable force field for different fluoropropene compounds. This molecular model has already been applied for predictive molecular simulation studies on the vapor-liquid phase equilibria in binary mixtures of the tetrafluoropropenes R-1234yf or R-1234ze(E) with the difluoromethane R-32 and CO2. In this work we present molecular dynamics simulations on the liquid phase properties of the pure fluoropropenes R-1234yf, R-1234ze, R-1234ze(E), and R-1216 and their binary mixtures with CO2 and R-32. Our study covers temperatures from 273 to 313 K, pressures up to 3.5 MPa, and different mixture compositions. We provide predictions on the densities and transport properties of the pure compounds and the binary mixtures to complement experimental data. Additionally, we have analyzed radial and spatial distribution functions in the systems to gain insight into their microscopic structures and preferred interaction sites.

“…As a very promising alternative refrigerant, R1234yf attracts more and more attention with zero ODP (ozone depletion potential) and a 100-year GWP (global warming potential) lower than 1. The heat transfer performance, saturated vapor pressure, and viscosity of R1234yf have been reported, − but the research on the potential applications in absorption refrigeration systems has not been reported. As absorbents DMETrEG (triethylene glycol dimethyl ether) and NMP have a high boiling point, weak toxicity, and good ability to dissolve many refrigerants, such as R134a, R161, and R32.…”

Isothermal Vapor–Liquid Equilibria of the Absorption Working Pairs (R1234yf + NMP, R1234yf + DMETrEG) at Temperatures from 293.15 K to 353.15 K

The vapor−liquid equilibria (VLE) data of R1234yf + NMP and R1234yf + DMETrEG were measured at the temperature range of 293.15−353.15 K in a dual cycle experimental apparatus. The thermodynamic consistency of the VLE data was checked with an area test. The VLE data were correlated by the nonrandom two-liquid model, and the results showed that they had a good agreement. The average relative deviation of pressure for R1234yf + DMETrEG was within 1.37% and its maximum was 3.51%; the average relative deviation of pressure for R1234yf + NMP was within 1.43% and its maximum was 3.65%. The results still showed that there was a large positive deviation between the binary system R1234yf + NMP and Raoul's law, and the system R1234yf + DMETrEG exhibited a slight positive deviation to the ideal solution.

“…However, there currently are few wide-ranging correlations for the viscosity of R1234yf or R1234ze(E). There is one extended corresponding states (ECS) model for the viscosity of R1234yf (Akasaka, 2010) and unpublished ECS models for both R1234yf and R1234ze(E) in REFPROP (Lemmon et al, 2013), and most recently a free-volume based model (He et al, 2015). In this work we develop correlations for the viscosity as a function of temperature and density that are valid over a wide range of fluid states including gas, liquid, and supercritical regions for R1234yf and R1234ze(E) and compare with known experimental data.…”

Due to concerns about global warming, there is interest in 2,3,3,3-Tetrafluoroprop-1-ene (R1234yf) and trans-1,3,3,3-Tetrafluoropropene (R1234ze(E)) as potential replacements for refrigerants with high global warming potential (GWP). In this manuscript we survey available data and provide viscosity correlations that cover the entire fluid range including vapor, liquid, and supercritical regions. The correlation for R1234yf is valid from the triple point (220 K) to 410 K at pressures up to 30 MPa, and the correlation for R1234ze(E) is valid from the triple point (169 K) to 420 K at pressures up to 100 MPa. The estimated uncertainty for both correlations at a 95 % confidence level is 2 % for the liquid phase over the temperature range 243 K to 363 K at pressures to 30 MPa, and 3 % for the gas phase at atmospheric pressure.
