| Abstract: | The water/LiBr pair has been widely used in absorption chillers. However, its performance is limited to a certain range of concentrations, due to the risk of salt crystallization. This prevents it from operating at high temperatures in the absorber and does not allow it to produce useful heat at suitable temperatures when functioning as heat pump. This limitation might be overcome by using Ionic liquids (ILs) as additives in the water/LiBr mixture which can improve thermophysical properties. One of the drawbacks of falling-film tubes is the non-uniform distribution of the film on the tube surface. Thermophysical properties of the new mixture as viscosity and surface tension will be of special importance for good wetting. This is a preliminary study on the influence of wettability in the absorption process of water by water/LiBr solutions in a falling film over horizontal tubes and 1,3- Dimethylimidazolium Chloride [dmim][Cl] as additive for heating and cooling purposes. |
