Abstract

<P>LA PRESENTE INVENTION CONCERNE UN ELEMENT ABSORBANT SERVANT A PRELEVER DE LA CHALEUR A LA TERRE OU A LUI EN DELIVRER.</P><P>POUR CELA, ON UTILISE UN SYSTEME D'ELEMENTS TUBULAIRES 1 TRAVERSES PAR UN LIQUIDE INSTALLES PEU EN PROFONDEUR QUI S'ETENDENT TOUS RADIALEMENT A PARTIR D'UN POINT DE RAMIFICATION EN FORMANT DES ANGLES DONNES PAR RAPPORT AU PLAN VERTICAL. LA LONGUEUR DES ELEMENTS TUBULAIRES 1 EST ADAPTEE AUX CONDITIONS LOCALEMENT RENCONTREES. CES ELEMENTS SONT REUNIS LES UNS AUX AUTRES A L'AIDE DE CONNEXIONS, D'ELEMENTS D'ACCOUPLEMENT 9 ET DE TUBES DE JONCTION 10 ET ILS SONT RELIES AUX CONDUITES DE CONNEXION 11, 12 D'UNE POMPE THERMIQUE OU D'UN COLLECTEUR SOLAIRE. CES ELEMENTS SONT LOGES DANS UNE FOSSE 8.</P><P>L'INVENTION SERT NOTAMMENT AU CHAUFFAGE DE MAISONS ET D'IMMEUBLES.</P>
The absorber device recovers heat from or transmits it to the ground. It comprises a large number of pipes coupled together and through which a heat transfer fluid flows. The pipes (1) emanate radially from a junction point (1A) near the ground surface, and are inclined to the vertical. They can extend at different angles to the vertical, so as to exchange heat with a semi-circular section of the ground, typically between 10 and 80 deg. of angle. Their lengths can be such as to suit ground conditions.
