摘要

Improvements made to the manufacture of thermodynamic heating devices according to the principle of the heat pump, characterized in that the hot exchanger and the cold exchanger are each constituted by a group of several elementary exchangers, each of which is connected with an elementary exchanger of the other group by means of an independent circuit in which a separate refrigerant fluid circulates, and which includes its own compressor and its own pressure reducer.
