The invention relates to a thermodynamic circuit (9) with a working medium comprising at least two substances with non-isothermal evaporation and condensation whereby the working medium can decompose above a given temperature. According to the invention, the heat from heat sources (AG) at temperatures above the decomposition temperature of the working medium may be made useful with little complexity and with high operational security, whereby the heat from the heat source (AG) is transferred in a first step to a hot liquid circuit (4) and, in a second step, from the hot liquid circuit (4) to the circuit (9) with the working medium comprising at least two substances with non-isothermal evaporation and condensation. The heat introduced to the circuit (9) with the working medium comprising at least two substances with non-isothermal evaporation and condensation can be reduced by means of the intermediate hot liquid circuit (4), such that a decomposition of the working medium can be avoided. Furthermore, the circuit (9) with the working medium comprising at least two substances with non-isothermal evaporation and condensation is embodied as a standardised solution for use with differing heat sources each at differing temperatures, whereby matching to the temperature of the heat source (AG) is achieved by means of the intermediate hot liquid circuit (4).

METHOD AND DEVICE FOR EXECUTING A THERMODYNAMIC CYCLE PROCESS
The aim of the invention is to reduce the complexity of a cyclic process. To this end, the pressure of a liquid working substance flow (13) is increased and a first partially evaporated working substance flow (15) is produced by the partial condensation of a working substance flow (12) with a low surface tension. Further evaporation of the first partially evaporated working substance flow (15) with heat transmitted by an external heat source (20) produces a second at least partially evaporated working substance flow (18). In said second at least partially evaporated working substance flow (18), the vaporous phase (10) is separated from the liquid phase, the energy of the vaporous phase (10) is converted into a usable form, and a vaporous phase (11) with a low surface tension is combined with the liquid phase (19) in such a way as to form the working substance flow (12) with a low surface tension. The liquid working substance flow (13) is, in turn, obtained by complete condensation of the partially condensed working substance flow (12a) with a low surface tension.

METHOD AND DEVICE FOR CARRYING OUT A THERMODYNAMIC CYCLE
The invention relates to a liquid working substance flow (13), the pressure of said flow being increased and the flow itself being subdivided into a first partial flow (16) and a second partial flow (17). The first partial flow (16) is partially evaporated with heat from a heat source (20), and the second partial flow with heat from a working substance flow (11) with a low surface tension. The two partial flows are then combined and produce a gaseous working substance flow (10) with heat from the heat source (20). The surface tension of said gaseous flow is reduced and the energy thereof converted into a usable form. The working substance flow (11) with a low surface tension is condensed, thus producing the liquid working substance flows (13). According to the invention, the first partial flow (16) and the liquid working substance flow (13) are essentially at the same temperature. In this way, the heat of the heat source (20) can be better used, thus increasing the efficiency of the cycle.
