Récupération de chaleur à basse température à l'aide d'un appareil frigorifique.

Low temperature waste heat power recovery using refrigeration equipment.

Résumé

The paper describes the development of a bottoming cycle system enhancing the efficiency of distributed gas power generation equipment such as micro turbines and recipe engine gensets. This so-called Organic Rankine Cycle (ORC) is a vapour power cycle with refrigerant (an organic fluid) instead of water/steam as the working fluid. Functionally it resembles the steam cycle power plant: a pump increases the pressure of condensed liquid refrigerant. This liquid is vaporized in an evaporator/boiler by extracting waste heat from the turbine or engine exhaust. The high-pressure refrigerant vapour expands in a turbine, producing power. The low-pressure vapour leaving the turbine is condensed before being sent back to the pump to restart the cycle. For refrigerants with certain properties, commercially available air-conditioning and refrigeration equipment with its proven reliability and performance record can be used cost-effectively in a power producing ORC system.
