Prediction of Thermodynamic Properties of Refrigerants in the Superheated Ragion

Abstract

This paper demonstrates the capabilities of the PFGC-MES equation of state (EOS) for calculating the thermodynamic properties in the superheated region for pure refrigerants. In addition the ability of this EOS is also tested for predicting the VLE behavior of binary mixtures. For pure compounds several properties in the superheated region are predicted. The calculated results and the experimental data are presented as pressure-enthalpy diagrams and also summarized in tables for five selected refrigerants. For mixtures the predicted results for different properties are also compared with the experimental data.
