    Vapor-Liquid Equilibria of Alternative Refrigerants and Their Binaries by Molecular Simulations Employing the Reaction Gibbs Ensemble Monte Carlo Method

  • Original language description

    Alternative refrigerants HFC125 (CHF2CF3) and HFC 134a (CF3CH2F) are modeled as a dipolar two-center LennardůJones fluid and alternative refrigerant HFC32 (CH2F2) is modeled as a dipolar LennardůJones fluid. We calculate vaporůliquid equilibria of theserefrigerants by GibbsůDuhem integration and vaporůliquid equilibria of two binaries (HFC 125 + HFC 134a and HFC 134a + HFC 32) by the reaction Gibbs ensemble Monte Carlo method. Potential parameters of the model are fitted to the critical temperature andvaporůliquid equilibrium data. The predictions are very good, and of comparable accuracy to those obtained using the Wilson and the UNIFAC thermodynamic-based approaches, even though such approaches use experimental mixture information.

    Rovnováha kapalina-pára alternativních chladiv a jejich směsí pomocí molekulárních simulací užitím Monte Carlo metody v reakčním Gibbsově souboru

  • Czech description

    Pro modely alternativních chladiv byla předpovězena rovnováha kapalina-pára pomocí molekulárních simulací. Předpověď byla porovnána s klasickými termodynamickými modely. Shoda byla velice dobrá i přesto, že simulace používají na rozdíl od termodynamických modelů pouze minimum experimentálních údajů pro adjustaci modelů.
