Technologie de cycle à coabsorbant pour récupération thermique à partir de sources de chaleur à basse température.

Coabsorbent cycle technology for low grade sources thermal recovery.

Auteurs : STAICOVICI M. D.

Résumé

Based on the coabsorbent cycles, recently introduced by the author, a particular new technology can be developed for feasible heat pumping applications. One of its main important features is its high potential in the thermal recovery of low grade natural or industrial heat/sink pairs of sources, usually outdistanced by 25 to 40°C, for efficient heat pumping and power production. After a short introduction of the coabsorbent cycle principle, the paper presents a few theoretical applications of heating and cooling with hybrid/absorption truncated and nontruncated coabsorbent cycles, supplied by different sources. In one of them, the possible coupling of the coabsorbent technology with the existing thermal power stations is proposed and studied from the district heating and cooling point of view. Power applications are also analyzed in conjuncture with different heat/sink natural/industrial sources, emphasizing the direct coabsorbent cycle based power generation role which this could play in the future for clean power production. A final application is related to the multi-functional coabsorbent units which could use low grade heat/sink sources for combined or separate heating, cooling and power production and could be characterized by efficiency and a compact design.
