abstract

  • A review on the use of nanoparticles to improve the performance of absorption chillers is presented. The review includes a compilation and discussion of research data on the subject using as base fluids NH3-H2O, H2O-LiBr and other solutions. Topics analysed include: theoretical and experimental studies about mass transfer enhancement in absorbers and desorbers; research to improve performance of complete absorption chillers; evaluation of thermophysical properties and stability of nanofluids, including viscosity, surface tension, thermal conductivity and other properties; and other studies with results useful for implementation in absorption chillers. Trends about the use of nanofluids in absorption systems, type and concentration of nanoparticles that provide the best performances and specific topics that require more research are identified from the review. Strategies are proposed for future research or for decision makers related to absorption chillers.
