Résumé

Two design concepts for a desorber in small-capacity ammonia-water absorption systems are presented. Both designs implement the thermodynamically favorable diabatic distillation concept and rely on liquid-vapor counter flow. Counter current flow limitations as well as component activation thresholds inherent to these designs are investigated. A hydrodynamic design methodology is established and evaluated experimentally through air-liquid flow visualization studies that simulate expected flow patterns. Parameters required for coupled heat and mass transfer modeling of these designs are identified and quantified experimentally through high-speed videography. The hydrodynamic feasibility of both designs is verified and design guidance to achieve optimal operation is provided. The results of this study can guide further development of highly compact and efficient desorption components required for optimal thermal compressors.
