Device for utilizing geothermal heat and method for operating the same

摘要: The invention relates to a device for utilizing geothermal heat comprising at least one first channel (10) through which working material (12) is conducted downward into the interior of earth and second (14) upward in direction toward earth's surface, whereby channels (10, 14) form system that sealed off from soil. provides via throttling area (15, 16), 16) throttles (12), primarily liquid flow front vaporization pressure (18, 20) so can be, large extent, completely vaporized after 16).
