摘要：
The ability of three equations of state (EOS) for describing the vapor-liquid equilibria of refrigerants has been studied for several binary mixtures. The three uations of state studied were the Soave-Redlich-Kwong (SRK), Peng-Robinson (PR) and Parameters From Molecule Contribution (PFMC). For azeotropic mixtures, the bubble point pressure, vapor molar volume, saturated liquid density, and heat of vaporization were calculated and compared with the values reported in the ASHRAE hand- book. Binary interaction parameters for each equation of state were optimized to achieve better agreement between calculated values and the reported experimental data. The optimized binary interaction parameters for several binary mixtures are presented. Sample graphical error analyses are shown.
