چکیده انگلیسی
The density of three hydrofluoroethers (HFEs) in extended ranges of temperature and pressure has been calculated using a new equation of state (EoS) and the results are shown as three-dimensional surfaces of density-temperature-pressure. A wide comparison with experimental data was made. The accuracy of the equation of state was determined by the statistical parameters. The results show that the equation of state reproduces the experimental PVT data of HFEs within experimental errors throughout the liquid phase. The thermodynamic properties such as isobaric expansion coefficient, isothermal compressibility, internal pressure, the difference between isobaric and isochoric heat capacities, and vapor-liquid equilibrium (VLE) prediction for these hydrofluoroether (HFE) refrigerants have been performed using this EOS.
