Resumen
In this work, the performance of new proposed 2,2,2-trifluoroethanol/ionic liquid mixtures for absorption heat transformer applications is studied. The 1-ethyl-3-methylimidazolium tetrafluoroborate ([emim][BF4]) and 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF4] have been selected as new absorbent for absorption heat transformer systems with 2,2,2- trifluoroethanol (TFE) as refrigerant. The selection of these ionic liquids is based on a computationalexperimental study to select suitable ionic liquids with optimized properties for TFE absorption applications. The performance of these two TFE/ionic liquid mixtures is analysed and evaluated. The solution concentration (i.e. refrigerant in ionic liquids) in absorber and generator are predicted based on experimental vapour-liquid equilibrium data. The experimental data of both vapor liquid equilibrium and excess enthalpy of the mixture are correlated using Non-Random Two Liquid (NRTL) method available in Aspen Plus ...
