In order to improve the performance of the absorption refrigerator, we investigated the characteristics of horizontal tube-type and vertical plate-type equipments as absorber or generator using water-LiBr system. The horizontal tube-type is used widely as absorber and the vertical plate-type has good performance of heat/mass transfer because of large surface area per unit volume. We examined the effects of heating/cooling water temperatures and the surfactant (1-octanol) concentrations on the efficiencies of two type equipments. The experimental results say that the observed values of the absorption/generation rates for the vertical plate-type used as absorber were much greater than those for the other types. In addition, the observed values of the absorption/generation rates were compared to the calculation values based on heat/mass transfer in LiBr solution film and the observed values were almost equal to the calculation values without the surfactant addition. With surfactant addition, the observed values for the vertical plate-type used as absorber was remarkably increased.
