The object of this paper is to study the effects of nanofluid on NH3/H2O bubble absorption performance under adiabatic and non-adiabatic conditions. Mono nano Ag with the concentration of 0.02wt% was used as the enhancement medium, and the absorption performance experiments under the heat insulation and water cooling for absorption test section were respectively conducted and contrastively analyzed. The results showed that the absorption rate with mono nano Ag in bubble absorption process is higher than that without any nanoparticles; in adiabatic case, when the initial temperature of NH3/H2O solution is gradually increased within 6~18°C, the absorption rate decreases correspondingly, and so does the effective absorption ratio; in non-adiabatic case, with the cooling water temperature rising within 10~25°C, the absorption rate decreases but the effective absorption ratio increases. Therefore, it is concluded that the heat transfer enhancement of nanofluid can promote the NH3/H2O bubble absorption performance to a certain degree, and the enhancement of the absorption is not completely dependent on heat transfer.
