HCFCs, FCs and hydrocarbons with several empirical equations Some works have beenД¬onducted to correlate the phase behavior of mixtures of CFCs, Important for the application of their uses. An accurate description of the thermodynamic properties and phase equilibria of those compounds is very Physical and chemical properties to CFCs should be invented toД¬ope with this situation. Many countries haveДecided to freeze the use of CFCs by replacing them with hydrochlorofluorocarbons (HCFCs) and finally stop their production until the end of 1995, and thus substitutes that would have similar Versatile applications such as refrigeration. Some of the most harmful chemicals with respect to ozone layerДЄre chlorofluorocarbons (CFCs) which are extensiw ly used for Key words: CFC, HCFC, FC, Vapor-liquid Equilibria, Mixing Rule Huron-Vidal second order model showed good convergence ability, which was due to its robustness to parameter Showed the superiority to the other models in predicting the VLE of freon mixtures with low errors.
