<p>The application discloses an organic Rankine Cycle system with a generating unit, a condenser for condensing an organic work fluid, a feeder pump for circulating the organic work fluid and an evaporator (14) for evaporating the organic work fluid. The generating unit comprises a high-pressure screw expander and a low-pressure screw expander, which are connected in series, wherein the high-pressure screw expander and the low-pressure screw expander are mechanically connect- able to a generator, which is provided between the high- pressure screw expander and the low-pressure screw expander. The ORC system comprises a by-pass line for bypassing the high-pressure screw expander. The bypass line comprises a control valve for opening and closing the by-pass line.</p> |
