Algorithm for non-azeotropic ternary refrigerant mixture thermodynamic properties

To calculate the properties accurately,a new model which combines PRHV with Lee-Kesler-Plǒcker(LKP) was proposed.The PRHV model,which uses Huron-Vidal original mixture rules,PR equation and NRTL excess Gibbs free-energy model,is used to predict mixture vapor liquid equilibrium data.Based on the equilibrium data predicted by PRHV,LKP model is used to get the ternary mixture thermodynamic properties such as enthalpy,entropy.The model is proved to be reliable and accurate and can be used as an accurate method for various kinds of refrigerants properties prediction.
