Experimental study of a reverse rectifying column for a heat transformer.

Etude expérimentale d'une colonne de rectification inverse pour un thermotransformateur.

Author(s) : LABIDI J., LE GOFF P., PARIS J.

Summary

Most absorption heat pumps or heat transformers currently in operation have a one-stage absorber, which limits the temperature lift and the exergetic efficiency of this type of apparatus. There are two possible ways to improve temperature lift and exergetic efficiency. The more common is to use an absorber with several stages operating at different pressures; the second is to use an absorber as a reverse-rectification column, equivalent to a large number of theoretical equilibrium stages operating at the same pressure. Such a reverse-rectification absorber can constitute the main element of an absorption heat pump. Experimental results are given for the water-ethylene-glycol mixture.
