Abstract

The objectives of this study are to investigate the combined heat and mass transfer enhancement using binary nanofluids as a working fluid in a H 2O/LiBr absorber. The result of heat and mass transfer experiment with the additives (arabicgum, 2E1H) showed that the heat and mass transfer performance of binary nanofluid with 2E1H enhanced significantly. In the case of 0.01 wt% Al 2O 3 binary nanofluids with 2E1H, the vapor absorption rate increased up to 77% in comparison with that without the additives. The heat transfer rate of 0.01 wt% Al 2O 3 binary nanofluids with 2E1H increased up to 19%. Based on the experimental results, it is recommended that the Al 2O 3 binary nanofluid be good with 2E1H to improve the heat and mass transfer performance.
