本研究的目的是探讨在水/溴化锂吸收器中使用二元纳米流体作为工作流体的联合传热和传质增强。添加剂（阿拉伯胶、2 E1 H）的传热传质实验结果表明，添加2 E1 H后，二元纳米流体的传热传质性能明显提高。在0.01wt%Al2O3二元纳米流体与2 E1 H的情况下，蒸汽吸收率增加到77%，与没有添加剂相比。0.01wt%Al2O3二元纳米流体与2 E1 H的传热率增加了19%。基于实验结果，建议Al 2 O3二元纳米流体与2 E1 H配合使用，以改善传热传质性能。
The objectives of this study are to investigate the combined heat and mass transfer enhancement using binary nanofluids as a working fluid in a H2O/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% Al2O3 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% Al2O3 binary nanofluids with 2E1H increased up to 19%. Based on the experimental results, it is recommended that the Al2O3 binary nanofluid be good with 2E1H to improve the heat and mass transfer performance.
