Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von U-förmigen Erdwärmesonden, die direkt als Verdampfer an
Resumen
eine Wärmepumpe anschliessbar sind. Ausgehend von den Nachteilen des bekannten Standes der Technik soll ein Verfahren
geschaffen werden, das zu erheblichen Einsparungen an Material und Kosten sowie verbesserten anwendungstechnischen
Eigenschaften der Sonde führt. Hierzu wird als Lösung folgende Verfahrensweise vorgeschlagen. Ausgehend von zwei auf einer
Trommel 1 aufgewickelten kunststoffummantelten Kupferrohren 2, 3 werden deren Enden abisoliert. Entweder auf ein Ende oder
auf jedes der Enden der Kupferrohre 2, 3 wird ein Schrumpfschlauchstück 4a, 4b aufgeschoben, derart, dass die abisolierten
Endabschnitte
2a,
3a
der
Kupferrohre
frei
bleiben.
Auf diese wird ein separat hergestelltes U-förmiges Rohrstück 5 aus Kupfer geschoben, fixiert und druckdicht befestigt. Die
Schrumpfschlauchstücke 4a, 4b werden anschliessend soweit zurückgeschoben, dass das U-förmige Rohrstück 5, die vorhandene
PE-Ummantelung und die Verbindungsstellen 7 zwischen dem U-förmige Rohrstück 5 und den Enden der Kupferrohre 2, 3
vollständig überdeckt sind. Anschliessend werden die aufgezogenen Schrumpfschlauchstücke erwärmt und aufgeschrumpft.
Danach wird auf den U-förmigen Rohrsondenabschnitt eine vorgefertigte Kunststoffkappe 7 bis zur Überdeckung der
Verbindungsstellen 6 aufgeschoben und durch Erwärmung aufgeschrumpft. Der Innenraum der Kunststoffkappe 7 wird mit einer
Vergussmasse 8 ausgegossen. Nach erfolgter Aushärtung wird das restliche Ende der Kupferrohre der fertigen Erdwärmesonde
wieder auf die Trommel aufgewickelt.

[Problem] To provide a large capacity geothermal heat exchange well
Resumen
for which the capacity as a geothermal heat exchange well is increased
and that has a structure that does not require a deep well. [Solution] A
large capacity geothermal heat exchange well is characterized in that:
a porous sleeve pipe is placed in a vertical hole opened in the ground
with a fixed gap from the inner wall of a vertical hole
the gap region is made to be a permeable structure by way of filling
the gap between the pipe and the inner wall of the vertical hole with a
material, such as gravel, having good permeability
a heat exchange duct for allowing a heat exchange medium to flow is
inserted into the pipe and then is connected to an inlet and a discharge
port
of
equipment
to
be
used
the ground water in the pipe is heated and caused to flow up by way of
heat radiated by the heat exchange medium in the pipe by causing heat
exchange medium to circulate between the duct and the equipment to
b e
u s e d
in addition, a convective flow occurs around the pipe by new ground
water from the periphery flowing in the lower section of the pipe
and the radiated heat is widely dispersed to the surroundings by the
occurrence of such convective flows, thereby significantly increasing
the capacity as a geothermal heat exchange well.

The invention relates to a method and an arrangement for providing
Resumen
heat (Qout) for a district heating supply (40): Heat (Qin) at a first
temperature level (T41, T42) is provided by means of a thermal water
conveying system (20) from a geothermal source (41). By operating a
high-temperature heat pump (43) and thermally connecting same to
the geothermal source (41), the thermal water can be conducted
through the evaporator (431) of the high-temperature heat pump (43)
and the heat (Qin) thereof can be transferred to the evaporator (431) of
the high-temperature heat pump (43). The condenser (433) of the
high-temperature heat pump (43) then supplies heat (Qout) at a
second, higher temperature level (T43, T47) to the district heating
network (40). A high-temperature compression heat pump (43) is
preferably used as the high-temperature heat pump (43). The second,
higher temperature level (T43, T47) achieved in this manner is above
100 DEG C.
