| 摘要 |
The present invention relates to a device for performing an ORC process, comprising a first circuit (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) arranged downstream of the evaporator (14) in order to expand the evaporated first process fluid (18), wherein the expansion machine (22) can be connected to a generator (26) for generating electrical energy; a first condenser (28) arranged downstream of the expansion machine (22) in order to condense the expanded first process fluid (18); and a first fluid energy machine (34) arranged downstream of the first condenser (28) in order to increase the pressure of the condensed first process fluid (18) and to convey the first process fluid (18) to the evaporator (14), which is located downstream of the first fluid energy machine (34). The device further comprises a second circuit (40), in which a second process fluid (42) is conducted through the first condenser (28) and evaporated there, the second circuit (40) comprising: a second fluid energy machine (44) arranged downstream of the first condenser (28) in order to compress the evaporated second process fluid (42); a second condenser (48) arranged downstream of the second fluid energy machine (44) in order to condense the evaporated second process fluid (42), wherein the first process fluid (18) can flow through the second condenser (48); and a throttle (50) arranged downstream of the second condenser (48) in order to restrict the condensed second process fluid (42), wherein the expansion machine (22) can be connected to the generator (26) without a gear unit by means of a shaft (30). |
