Experimental investigation and model verification for a GAX absorber.

Author(s) : PALMER S. C., CHRISTENSEN R. N.

Summary

In the ammonia-water generator-absorber heat exchange (GAX) absorption heat pump, the heat and mass transfer processes which occur between the generator and absorber are the most crucial in assuring that the heat pump will achieve COPs competitive with those of current technologies. A model is developed for the heat and mass transfer processes that occur in a counter-current vertical fluted tube absorber with inserts. Comparison of model results with experimental data provides insight into model corrections necessary to bring the model into agreement with the physical phenomena observed in the laboratory.
