Résumé

This article describes the principle of an innovative heat transformer cycle using a working mixture that is partially miscible at low temperature. Hence, the separation step, classically done by distillation in an absorption heat pump, is replaced by a costless one in terms of energy, obtained by simply cooling down the mixture. Results of the operation of a laboratory scale pilot unit are presented. The machine operating on an n-heptane-DMF mixture has enabled an 8 °C temperature lift with thermal efficiency varying from 30 to 40%. Hence, the practical feasibility of such a cycle was demonstrated.
