Device for generating electrical energy by means of an orc-circular flow

Abstract

The present invention relates to a device for performing an ORC-process, comprising a first circular flow (16) in which a first process fluid (18) is conducted, having an evaporator (14) for evaporating the first process fluid (18), an expansion machine (22) located downstream of the evaporator (14) for expanding the evaporated first process fluid (18), wherein the expansion machine (22) is connectable to a generator (26) for generating electrical energy, a first condenser (28) located downstream of the expansion machine (22) for condensing the expanded first process fluid (18), and a first fluid energy machine (34) located downstream of the first condenser (28) for increasing the pressure of the condensed first process fluid (18) and for transporting the first process fluid (18) to the evaporator (14) that is located downstream of the first fluid energy machine (34). The device further comprises a second circular flow (40) in which a second process fluid (42) is conducted through the first condenser (28) and is evaporated therein, wherein the second circular flow (40) comprises a second fluid energy machine (44) located downstream of the first condenser (28) for compressing the evaporated second process fluid (42), a second condenser (48) located downstream of the second fluid energy machine (44) for condensing the evaporated second process fluid (42), wherein the first process fluid (18) can flow through the second condenser (48), and a throttle (50) located downstream of the second condenser (48) for throttling the condensed second process fluid (42), wherein the expansion machine (22) is connectable with the generator (26) by a shaft (30) without gearing mechanism.
