VIOREL FEROIU, DAN GEANA Vapour - Liquid Equilibrium and Thermodynamic Properties of Refrigerants R143a and R152a from Cubic Equations of State

Abstract:

Vapour - liquid equilibrium and thermodynamic properties were predicted, along the saturation curve and in the single-phase region for refrigerants R143a (CF3CH3) and R152a (CHF2CH3). Five cubic equations of state were used: Soave-Redlich-Kwong (SRK), Peng-Robinson (PR), Schmidt-Wenzel (SW), Freze et al. (C1) and GEOS3C. A wide comparison with experimental data was made. So far GEOS3C, with three estimated parameters, compares favorably to other equations in literature, being simple enough for applications. Keywords: equation of state, vapour - liquid equilibrium, thermodynamic properties, refrigerants
