Geothermal collectors |
|
F24T 10/10
|
Geothermal collectors with circulation of working fluids through underground channels, the working fluids not coming into direct contact with the ground |
|
F24T 10/13
|
Geothermal collectors with circulation of working fluids through underground channels, the working fluids not coming into direct contact with the ground using tube assemblies suitable for insertion into boreholes in the ground, e.g. geothermal probes |
|
F24T 10/15
|
Geothermal collectors with circulation of working fluids through underground channels, the working fluids not coming into direct contact with the ground using tube assemblies suitable for insertion into boreholes in the ground, e.g. geothermal probes using tubes assembled with connectors or with return headers |
|
F24T 10/17
|
Geothermal collectors with circulation of working fluids through underground channels, the working fluids not coming into direct contact with the ground using tube assemblies suitable for insertion into boreholes in the ground, e.g. geothermal probes using tubes closed at one end, i.e. return-type tubes |
|
F24T 10/20
|
Geothermal collectors using working fluid injected directly into the ground, e.g. using injection wells and recovery wells |
|
F24T 10/30
|
Geothermal collectors using underground reservoirs for accumulating working fluids or intermediate fluids |
|
F24T 10/40
|
Geothermal collectors operated without external energy sources, e.g. using thermosiphonic circulation or heat pipes |
