Design and construction of backfilled and grouted borehole heat exchangers

This document covers standardization in the field of geological and environmental aspects, design, construction, operation, monitoring, maintenance and decommissioning of grouted borehole heat exchangers for uses in geothermal energy systems.
This document is only applicable for backfilled and grouted boreholes, it is not applicable for groundwater-filled boreholes.
Direct expansion and thermal syphon techniques are excluded from this document.

Planung und Bau von Erdwärmesonden

Dieses Dokument befasst sich mit der Normung von Erdwärmesonden für geothermische Anwendungen unter geologischen und Umweltaspekten und deckt dabei die Bereiche Auslegung, Ausführung, Betrieb, Überwachung, Wartung und Stilllegung von Erdwärmesonden in verpressten Bohrlöchern ab.
Dieses Dokument gilt nur für verfüllte und verpresste Bohrlöcher; es gilt nicht für grundwassergefüllte Bohrlöcher.
Techniken mit direkter Ausdehnung und Thermosiphonen werden in diesem Dokument nicht behandelt.

Conception et construction de sondes géothermiques verticales comblées et remplies de coulis

Le présent document concerne la normalisation des aspects géologiques et environnementaux de la conception, de la construction, du fonctionnement, de la surveillance, de la maintenance et du démantèlement des sondes géothermiques verticales remplies de coulis, pour les applications en géothermie.
Le présent document est uniquement applicable aux forages comblés et remplis de coulis, et non aux forages remplis d’eau souterraine.
Les techniques de détente directe et de thermosiphon sont exclues du présent document.

Zasnova in zgradba zasutih in z malto zalitih vrtinskih toplotnih izmenjevalnikov

Ta dokument zajema standardizacijo na področju geoloških in okoljskih vidikov, projektiranja, vrtanja, gradnje, izvedbe, delovanja, spremljanja, vzdrževanja, obnove in razgradnje izmenjevalnikov toplote v vrtinah za izkoriščanje geotermalne energije.
Tehnike neposrednega širjenja in termosifonske tehnike so izključene iz tega dokumenta.
