Abstract

Pour effectuer une activation du boyau en béton pendant la nuit et pour délivrer une capacité de rafraîchissement supplémentaire pour le fonctionnement en pointe de charge pendant le jour, l’invention réalise un arrangement de conduites (10) pour équilibrer la température de bâtiments, lequel dispose d’une seule conduite d’aller (12) et d’une seule conduite de retour (20). Un premier et un deuxième circuits d’équilibrage de la température (26, 28) sont dérivés de manière connue de ces conduites. Le sens de circulation à l’intérieur de la section finale d’aller (16) de la conduite d’aller (12) et de la section finale de retour (24) de la conduite de retour (20) peut ici être inversé par le biais d’une vanne d’inversion (42). Ces sections finales remplissent ainsi une fonction d’aller ou de retour, suivant le sens de circulation. Des clapets anti-retour (38, 40) à l’intérieur des sections d’extrémité d’aller et de retour (16, 24) contribuent à ce que le fluide d’équilibrage de la température qui quitte le circuit d’équilibrage de la température respectivement actif (26 ou 28) ne puisse pas pénétrer dans le circuit d’équilibrage de la température non activé concerné (28 ou 26).
