Résumé

In this work, the authors have used a simple equation of state to calculate the density of five lubricant/refrigerant mixtures including octane/dimethyl carbonate, TriEGDME/HFC-134a, TEGDME/HFC-134a, heptane/TEGDME, and decane/dimethyl carbonate at different temperatures, pressures, and compositions. The excess molar volumes of these mixtures have been calculated using this equation of state. Also, the authors have computed other thermodynamic properties such as isobaric expansion coefficient, isothermal compressibility, and internal pressure, for octane/dimethyl carbonate system for which the corresponding experimental values are available. A wide comparison with experimental data has been made for each thermodynamic property. The values of statistical parameters between experimental and calculated properties show the ability of this equation of state in reproducing and calculating of different thermodynamic properties for studied mixtures.
