ResumoWe use an extended corresponding states model to predict the thermal conductivity of pure halocarbon refrigerants and refrigerant mixtures. The model uses R134a (1,1,1,2-tetrafluoroethane) as the reference fluid, and we present a correlation, including critical enhancement, for the thermal conductivity of R134a. We give sample results comparing the model predictions with experimental data for pure halocarbon refrigerants and refrigerant mixtures; typically, the uncertainty of the predictions is 5–10 percent.
