Abstract

As a widely used absorption refrigeration working pair, H₂O/LiBr has excellent thermodynamic properties and environmental friendly characteristics. Nevertheless, it still has problems of crystallization, corrosion and low coefficient of performance (COP). In this paper, the effects of additives such as alcohols, salt mixtures, ionic liquids and nanoparticles on the heat and mass transfer, anti-crystallization and anti-corrosion of H₂O/LiBr were summarized. Besides, the theoretical and experimental research status of main components such as absorber and generator were introduced. Research results of the absorption refrigeration cycle optimization were also reviewed. Finally, the existing problems and development trends of lithium bromide absorption refrigeration technology were discussed, which may provide some references for the future study.
