Title (EN) UNDERGROUND TANK USED AS A WATER SUPPLY TANK FOR HEAT PUMPS
(FR) RESERVOIR ENTERRE SERVANT DE RESERVOIR D"EAU D"ALIMENTATION POUR POMPES A CHALEUR
Abstract: front page image
(EN)A heat pump (2) intended for heating is connected to an underground water supply tank (10). This tank is heat insulated by a hard foam layer (16). The fluid returned from the heat pump runs through a bundle of tubes (17) coiled on the hard foam layer (16). The tubes (17) bring the return fluid in contact with the earth so that the cold return fluid heats up to the mean temperature of the surrounding earth before it returns to the water supply tank (10).
(FR)Une pompe a chaleur (2) destinee au chauffage est reliee a un reservoir d"eau d"alimentation enterre (10). Ce reservoir est isole thermiquement par une couche de mousse dure (16). Le fluide de retour de la pompe a chaleur traverse un faisceau de tubes (17) qui est bobine sur la couche de mousse dure (16). Les tubes (17) mettent le fluide retour en contact avec la terre de telle facon que le fluide de retour froid se rechauffe jusqu"a la temperature moyenne de la terre environnante avant qu"il ne retourne au reservoir d"eau d"alimentation (10).
