| 摘要 |
The invention comprises a first thermodynamic working circuit (1) employing carbon dioxide for the obtaining of energy by means of a power generator (8) of the system, characterised by the fact that said thermodynamic working circuit (1) is associated in parallel with a secondary ammonia absorption and evaporation circuit (2) which is sized to condense the carbon dioxide gas coming from the generator (8), said system featuring a device (5a,5b,5c) for the recovery of low-grade thermal energy (E) which is sized to evaporate ammonia from the solution of ammonia in the secondary circuit (2), a fraction of the low-grade thermal energy (E) captured by the device (5a,5b,5c) being susceptible to being used to superheat the carbon dioxide in the working circuit (1). |
