Summary
In a companion paper, we dealt with the problem of predicting the liquid behaviour of pure refrigerants. It is the purpose of the present paper to extend the use of the Hard Sphere De Santis (HSDS) model by associating it with mixing and combination rules to predict the liquid state densities for mixtures of halocarbon refrigerants.\nThe deviations obtained between the experimental data, available for binary and ternary mixtures, and the HSDS model have shown an uncertainly of 1.5% for T* <= 0.9. This was the uncertainty claimed for the model, when applied to pure fluids.
