This paper deals with characteristics of falling film absorber and condenser in the bottoming cycles which employ ammonia-water mixture as working fluid. The authors constructed a unique co-generation system, named ACGS, at the campus and are investigating various kinds of energy saving technologies under practical situations. ACGS has the power and the refrigeration cycles using ammonia-water mixture as working fluid at the bottoming stage. The absorber and the condensers largely affect the performance of both cycles. It is necessary to investigate the absorption process detailed condition for designing the absorber and condenser, because the condensation with absorption process of mixture is more complicated than a single medium. Then, liquid film condition of condenser was calculated with finite difference analysis. It shows the mass fraction distribution and temperature distribution, and the number of tubes and the tube length filled operating point.
