Vapor-liquid Equilibrium Data Concerning Refrigerant Systems (R116 + R143a)
Energy Procedia, 2012Co-Authors: Hakim Madani, Christophe Coquelet, Dominique RichonAbstract:Development of modern refrigeration systems is critical for the success of new global environmental protection efforts. The binary system of refrigerants: Hexafluoroethane (R116) + 1,1,1- trifluoroethane (R143a), has been studied with the aim of providing PTxy data. Isothermal vapor-liquid equilibrium data have been generated using the "static-analytic" method from 258 to 328 K at pressures from 0.39 to 3.89 MPa. The modelcomposed of the Peng-Robinson equation of state, the Mathias-Copeman alpha function, the Wong-Sandler mixing rules and the NRTL cell theory is applied herein to correlate the data and calculate the critical line.

Vapor-Liquid Equilibrium Data Concerning Refrigerant Systems: Equipment, Data and Modelling
2009Co-Authors: Hakim Madani, Christophe Coquelet, Dominique RichonAbstract:The development of modern refrigeration systems is critical for the success of new global environmental protection efforts; accurate thermo-physical data are of utmost interest for the development of new efficient refrigeration systems. For measurement purposes, a reliable "static-analytic" method taking advantage of two online micro capillary ROLSI™ samplers was used for all PTxy measurements presented herein. The binary systems of refrigerants that have been studied as an application of the experimental techniques are: - Hexafluoroethane (R116) + 1,1,1- trifluoroethane (R143a), from 258 to 328 K at pressures from 0.39 to 3.89 MPa - Hexafluoroethane (R116) + 1,1,1,2-tetrafluoroethane (R134a), from 263 to 353 K at pressures from 0.2 to 4.2 MPa - Carbon dioxide (R744) + 1, 1-difluoroethane (R152a) from 258 to 343 K at pressures from 0.14 to 7.65 MPa The model composed of the Peng-Robinson equation of state, the Mathias-Copeman alpha function, the Wong-Sandler mixing rules and the NRTL cell theory is applied to correlate the data and calculate critical lines.

Modeling of the thermodynamic properties of the mixtures: Prediction of the position of azeotropes for binary mixtures
Fluid Phase Equilibria, 2014Co-Authors: Saida Fedali, Hakim Madani, Cherif BougriouAbstract:Abstract In this paper, we present a novel approach to predict the location of azeotropes for binary mixtures by two methods: from the experimental data and the thermodynamic model. The model composed of the Peng–Robinson equation of state, the Mathias–Copeman alpha function, the Wong–Sandler mixing rules involving the NRTL model. The binary mixtures of refrigerants selected are: propane (R290) + 1,1,1,2-tetrafluoroethane (R134a) [1] , propane (R290) + difluoromethane (R32) [2] and Hexafluoroethane (R116) + ethane (R170) [3] , Hexafluoroethane (R116) + carbon dioxide (R744) [4] and Hexafluoroethane (R116) + propane (R290) [5] , to be favorable to the environment with a null ODP (ozone depletion potential) and a low GWP (global warming). The results prove that there is an agreement between the predicted values and the experimental data and the relative error does not exceed 2.76% for the molar fraction and 3.23% for the pressure. The presented methods are able to predict the azeotropic position and the performances of the models change from one mixture to another.
