heal.abstract	The non-equilibrium processes taking place in the H2O/LiBr Absorption Refrigeration Machine (ARM) units are studied. These two-phase flow processes of a pure substance (as H2O) or a binary mixture (as H2O/LiBr), with heat exchange with the ambient, are characterized by non-equilibrium states of the working medium (indicated by temperature and/or mass fraction deviations from equilibrium) which cause irreversibilities inside the flow followed by an entropy production. A thermodynamic method for the description of these non-equilibrium processes is developed. According to this method, the non-equilibrium two-phase flow processes (as these ones in the H2O/LiBr ARM units) are described by the 'non-equilibrium parameters' related with the non-ideality of the boundary conditions of the heat exchange with the ambient and the heat and mass exchange delay between the two streams of the two-phase flow. As an application of this thermodynamic method, a comparative parametric study of these non-equilibrium processes is realized for several values of the 'non-equilibrium parameters', from which, conclusions about the contribution of these parameters on the 'quality' of these processes are extracted.	en
