Abstract
Experimental study on the characteristics of several kinds of packing materials was carried out in order to get the optimum design data for the generator-GAX combined rectification system of an NH₃/H₂O absorption heat pump.


The mass and heat transfer phenomena of the rectification system were theoretically studied and the optimum locations for the injection of feed solution from solution-cooled absorber and the GAX desorber in generator were predicted. The total number of rectifing stages, the temperature of each stages and liquid/vapor flow rates in auxiliary rectifier column were determined to design the experimental apparatus for packed rectifier.


Experiments for several suitable packing materials in packed rectifier were performed and the result showed that the bulk of steel wire was the most effective packing material. The optimum volumetric packed rate in rectifier space was 36% by steel wire to make ammonia concentration over 99.98%. The condensation heat transfer of ammonia vapor by packing material in rectifier was analysed and its effect was presented.


These performance results can be adapted in rectifier design of NH₃/H₂O absorption heat pump.
