Résumé

One of the largest fields of research is energy recovery, particularly the increase of the energy level by using a heat pump. An absorption heat pump allows an upper level of about 140°C to be reached with a low consumption of electrical energy. The first part of this work establishes an expression for the COP from an enthalpy balance taking into account some hypotheses. From this expression a selection of the couple solute-solvant is possible according to operating conditions. A computation of the performance coefficient has been made as a function of various parameters such as the condenser, evaporator, absorber and separator temperature, and also the solution flow. Some results obtained with a small pilot plant are presented. They provide confirmation of the hypothesis and show that an absorption heat pump is able to increase the energy level from 60-80°C to 120-140°C with a satisfactory COP.
