Réfrigération Résumé : The objectives of this paper are to examine the effect of nanoparticles on the pool type absorption heat transfer enhancement and to find the optimal conditions to design a highly effective compact absorber for NH3/H2O absorption system. The binary nanofluids which mean binary mixture with nano-sized particles are tested to apply nanofluids to the absorption system. Al2O3 and carbon nanotube (CNT) particles are added to make the binary nanofluids in the binary mixture of NH3/H2O. The effect of Al2O3 nanoparticles and CNT on the absorption performance is studied experimentally. The experimental ranges of the key parameters are 20% of NH3 concentration, 0–0.08 vol% (volume fraction) of CNT particles, and 0–0.06 vol% of Al2O3 nanoparticles. For the NH3/H2O nanofluids, the heat transfer rate and absorption rate with 0.02 vol% Al2O3 nanoparticles were found to be 29% and 18% higher than those without nanoparticles, respectively. It is recommended that the concentration of 0.02 vol% of Al2O3 nanoparticles be the best candidate for NH3/H2O absorption performance enhancement in the present conditions. It is expected that this study will give some basic idea to understand the heat and mass transfer enhancement mechanism in multi-components nanofluids.
