Condensation du NH₃ / H₂O avec des concentrations massiques entre 80% et 96%: étude expérimentale dans un échangeur de chaleur à plaque

High concentration NH₃/H₂O is suitable for Kalina cycles used for the recovery of low grade heat. Plate heat exchangers (PHEs) are compact and reduce the charge of working fluid. This paper investigates the condensation of NH₃/H₂O with NH₃ mass concentrations of 80%-96%. The vapor and...

Ammonia absorption in ionic liquids-based mixtures in plate heat exchangers studied by a semi-empirical heat and mass transfer framework

Unfavorable transport properties have always been pointed out as the key factors that hinder the application of ammonia/ionic liquids (NH ₃ /ILs) in absorption cycles, while heat and mass transfer of these new fluids in components have been rarely reported. In this study, a corrugated plate heat exchanger is selected as the...
