Abstract
The invention concerns a mechanism for operating a thermodynamic cycle, particularly a low-temperature power plant, as well as a related process, whereby a low-temperature mass stream (1) feeds a first heat stream to a working fluid (6) circulating in a first cycle at an initial temperature level (T1), whereby subsequent to an expansion of the working fluid in an expansion machine (7) a second heat stream is extracted from the working fluid (6) at a lower expansion temperature level (T5) with respect to the initial temperature level (T1) for an improvement of the energy exploitation of the thermodynamic cycle or the low temperature power plant, which is pumped to a higher pump temperature level and is fed to the low temperature mass stream (1) and/or fed at least partially to the first cycle.
