The invention relates to a liquid working substance flow, the pressure of said flow being increased and the flow itself being subdivided into a first partial flow and a second partial flow. The first partial flow is partially evaporated with heat from a heat source, and the second partial flow with heat from a working substance flow with a low surface tension. The two partial flows are then combined and produce a gaseous working substance flow with heat from the heat source. The surface tension of said gaseous flow is reduced and the energy thereof converted into a usable form. The working substance flow with a low surface tension is condensed, thus producing the liquid working substance flows. According to the invention, the first partial flow and the liquid working substance flow are essentially at the same temperature. In this way, the heat of the heat source can be better used, thus increasing the efficiency of the cycle.
