A collector hose filled with a carrier fluid (water or a combination of water and antifreeze) is installed in a borehole which is drilled into a geothermal aquifer. In colder months, this circulating carrier fluid absorbs heat from the surrounding bedrock, which is then extracted by the heat pump for use in space-heating via piping connected to the heat exchanger. During the warmer months the process is reversed: heat from the air is transferred to the heat exchanger and into the fluid. As it moves through the pipes, the heat is dispersed to the rocks, soil, and groundwater.</skos:scopeNote><skos:inScheme rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en"/><skos:broader rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31347230"/><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_ca/index.php?tema=9848754"> <skos:prefLabel xml:lang="ca">climatització geotèrmica</skos:prefLabel> </skos:Concept></skos:exactMatch><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_es/index.php?tema=14086742"> <skos:prefLabel xml:lang="es">geothermal heat pumps (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch>  <dct:created>2026-03-30 20:41:46</dct:created>  </skos:Concept></rdf:RDF>
