Résumé

This work aims at studying and developing a thermodynamic heat recovery cycle for the combined production of cooling capacity and low power electricity (5 kW of refrigeration, ~1 kW of electricity) using water/ammonia as working fluid. The target temperature range is low enough (80 to 160 °C) to suit on-road transportation, residential and various industrial heat recovery applications. Thermodynamic modeling of the cycle was carried out and a parallel architecture was proposed, in which the refrigerant vapor at the output of the generator can be used to feed the expander (production of electricity) and/or the condensation-expansion-evaporation part (cooling capacity). Various experimental and numerical works are presented : 1kW ammonia turbine is currently tested at the laboratory, steady-states and transient model. Furthermore a more advanced architecture was investigated to take benefit from the possibility of reverse mode of the expander.
