ABSTRACT = {A new architecture for absorption refrigeration systems (ARSs) that enables a significant enhancement of heat and mass transport processes has been 
proposed. This enhancement in performance is expected to translate into a significant reduction is size and cost of ARSs. The key innovation in the 
new approach is the use of ultrathin liquid films constrained by highly permeable nanostructured membranes. This approach enables far greater 
performance than those in the existing macroscale. For example, in the new absorber design, the thin film of LiBr solution is constrained by hydrophobic 
porous membranes and the inner wall of cooling water channel. The LiBr solution is held outside of the membrane by a meniscus formed over the 
membrane pores. The solution is cooled by water running in the cooling channel. This paper reports a detailed analysis based on molecular dynamics 
simulations to obtain a fundamental understanding on the nanoscale transport processes. The effects of LiBr concentration and the water vapor 
temperature elevation on the condensation coefficient and condensation mass fluxes have been evaluated. A model is also developed to predict the 
average condensation coefficient for a complete vapor energy spectrum. A comparison between the nanoscale and macroscale condensation mass fluxes 
is also provided.},
