Summary

The hydrofluoroolefin (HFO) refrigerant 1,1,2-trifluoroethene (HFO-1123, CF2 = CHF) and its blends are con- sidered next-generation refrigerants due to their zero ozone depletion potential (ODP) and low global warming potential (GWP). In this study, the saturation pressures of HFO-1123 and its binary blends diflu- oromethane (HFC-32) + 1,1,2-trifluoroethene (HFO-1123) and 1,1,1,2-tetrafluoroethane (HFC-134a) + 1,1,2- trifluoroethene (HFO-1123) under various compositions are computed in the temperature range of 230–330 K using a first ab initio COMPASS force field in molecular dynamics simulations. The estimates of other thermodynamic properties, such as the saturated densities of the pure compounds and their binary blends are provided to supplement experimental data. Moreover, the critical points of HFO-1123 and its binary blends with various compositions, along with their disparities, are also estimated.
