This paper presents an extensive review of heat and mass transfer correlations in the framework of sorption machines operating based on the falling film technology , in which ammonia-water and lithium bromide-water are used as the working fluid pairs. Heat and mass transfer correlations (Nu, Sh) as functions of falling liquid film flow regime (Re) are summarized as well as the application range and geometrical configuration. In order to compare the correlations found in the recent and classical literature, graphs were constructed for comparing purposes of those correlations trends within the application range of absorption refrigeration machines.
