The parameters from group contribution (PFGC) equation of state, as used by Moshfeghian, Erbar, and Shariat (PFGC-MES), is used to describe the thermodynamic behavior of 20 refrigerants. These refrigerants include pure halogenated compounds, azotropic mixtures of halogenated compounds, and ammonia. The parameters were determined by simultaneously fitting data for vapor pressure, saturated vapor and liquid volumes, and heats of vaporization using a standard nonlinear analysis program. All parameters for the 20 refrigerants are reported, as are the deviations between predicted and experimental data. These deviations are compared to those from the Soave-Redlich-Kwong equation state. The predicted and experimental {ital K} values for two binary mixtures of the pure halogenated compounds are also compared.
