Summary

The density of 11 refrigerants (hydrochlorofluorocarbons, HCFCs, and hydrofluorocarbons, HFCs) in the extended ranges of temperature and pressure has been calculated using Goharshadi-Morsali-Abbaspour equation of state (GMA EoS) and the results have been shown as the three-dimensional surfaces of density-temperature-pressure. A wide comparison with experimental data was made. The accuracy of the equation of state in the prediction of density was determined by statistical parameters. The results show that the GMA EoS can reproduce the experimental PVT data of HCFCs and HFCs within experimental errors throughout the liquid phase. The thermodynamic properties such as isobaric expansion coefficient, isothermal compressibility, and vapour-liquid equilibrium prediction for these HCFC and HFC refrigerants have been performed using GMA EoS. GMA EoS can predict the characteristic feature of pressure behaviour of isobaric expansion and isothermal compressibility coefficients.
