Geothermal power plant system, method for operating a geothermal power plant system and method for increasing the efficiency of a geothermal power plant system

摘要

The disclosure relates to a geothermal power plant facility, in particular utilizing the ORC method, wherein an and aspect thereof is that, for condensing the working fluid leaving a turbine, an air-cooled condenser and a water-cooled condenser are provided, which are connected in parallel to one another. A further aspect of some embodiments is a method for operating a geothermal power plant facility, wherein a step of the method is the separation of the working fluid to be condensed and the subsequent separate relay of the partial volume flows of the working fluid to an air-cooled condenser, on the one hand, and to a water-cooled condenser, on the other hand. Finally, a further aspect of some embodiments is a method for retrofitting a conventional geothermal power plant facility, additionally incorporating a water-cooled condenser which is connected in parallel to an air-cooled condenser.
