Abstract

The invention relates to a thermodynamic machine having a circulation system in which a working fluid, in particular a low-boiling working fluid, circulates alternately in a gaseous and a liquid phase, a heat exchanger, an expansion machine, a condenser, and a fluid pump. The invention also relates to a method for operating the thermodynamic machine. According to certain embodiments of the invention, in the flow line of the fluid pump, a partial pressure increasing the system pressure is applied to the liquid working fluid by adding a non-condensing auxiliary gas. Compact ORC machines can be implemented, preventing cavitation in the liquid working fluid.
