System for carrying out a thermodynamic cycle, assembly with such a system as well as motor vehicle with such an arrangement

The invention relates to a system (7) for carrying out a thermodynamic cycle, with a working fluid circuit (9), in which the thermodynamic cycle process can be performed. In this case, a heat storage device (11) (15) is provided which is adapted to receive heat from a heat source (5) and to provide heat to the working fluid circuit (9) to make, wherein the heat storage device (11) fluidically in series with a heat transport media path from a first heat source (5) associated heat transfer device (17) associated to a second working fluid cycle (9) heat transfer means (19) is arranged.
