| Outline of Final Research Achievements |
This work applied a multi-fluid approximation to low-GWP refrigerant mixtures such as R32/1234yf and R32/1234ze(E) mixtures, and successfully developed new mixture models for the thermodynamic properties of the mixtures. The models are capable of calculating the vapor-liquid equilibrium, density, heat capacities, and critical parameters of the mixtures within uncertainties comparable to their experimental values. In addition, this work produced several add-in modules for REFPROP for readily calculations using the mixture models.
