Abstract
From the viewpoint of the energy saving, it is an effective procedure to attempt the compactification and performance improvement of absorption water heater-chiller and is the improvement on heat and mass transfer characteristics of absorber and regenerator. In the physical method, the configuration improvement on absorbers and structure of generator and heating surface (tube), etc. of the shape is required. In this study, it was made that elementary process of heat transfer, which simultaneously, it is accompanied, by mass transfer in heat transfer process of plate type absorber, which established accordion pleated flow channel type was clarified to be purpose.
