Mathematical modeling and experimental verification of an absorption chiller including three dimensional temperature and concentration distributions

One of the main drawbacks in modeling absorption chillers is the lack of justified hypotheses of heat and mass diffusion in an annular flow on the outer surface of horizontal tubes. Heat and mass transfer in diffusion is a three-dimensional problem with vector characteristics. This paper introduces the characterization of vapor–absorbent heat and mass transfer phenomena in three dimensional space to obtain steady state simulation results for single effect LiBr–H2O absorption chillers.
