Title (EN) A SPACE-HEATING SYSTEM WHICH HAS AIR OR A LIQUID AS THE HEAT-TRANSPORTING MEDIUM
(FR) SYSTEME DE CHAUFFAGE D"UN ESPACE QUI UTILISE DE L"AIR OU UN LIQUIDE COMME MILIEU DE TRANSPORT DE CHALEUR
Abstract: front page image
(EN)Space-heating system which has a fluid as the heat-transporting medium. The system comprises a heat store (9) with a heat-storing medium through which the fluid can flow. The heat store (9) is in communication with two pressure-equalizing chambers (10, 11) arranged on either side of the heat store, one of which (10) normally has a higher temperature than he other (11), due to the heat storing. Each of the chambers is connected by means of a heat-transporting fluid duct (12) to a heating arrangement (13, 14, 15). With the aid of a fan or pumping element the fluid is made to flow from the heating arrangement (13, 14, 15) to the hottest chamber (10), through the heat-storing medium in the heat store (9) and into the coldest chamber (11), and thereafter back to the heating arrangement (13, 14, 15). When the fluid flows through the heat store (9) in this direction, the heat-storing direction, the heat-storing medium takes up heat from the heat-transporting fluid. According to the invention the heating system comprises another heat-transporting fluid duct (19) which connects the two said chambers (10, 11) to the space (20) which is to be heated. With the aid of a fan or pumping element the heat-transporting fluid is made to flow from the hottest chamber (10) via the space (20) to the coldest chamber (11) and through the heat-storing medium in the heat store (9) in a direction, the heat-withdrawal direction, which is opposite to the heat-storing direction, the fluid taking up heat from the heat-storing medium.
(FR)Un systeme de chauffage d"un espace utilise un fluide comme milieu de transport de chaleur. Le systeme comprend un magasin de chaleur (9) avec un milieu de stockage de chaleur au travers duquel le fluide peut circuler. Le magasin de chaleur (9) est en communication avec deux chambres d"egalisation de pression (10, 11) montees de chaque cote du magasin de chaleur, l"une d"elles (10) ayant normalement une temperature superieure a l"autre (11), ceci etant du au stockage de chaleur. Chacune des chambres est connectee a l"aide d"une conduite de fluide de transport de chaleur (12) a un dispositif de chauffage (13, 14, 15). A l"aide d"un ventilateur ou d"un element de pompage on fait circuler le fluide du dispositif de chauffage (13, 14, 15) vers la chambre la plus chaude (10), au travers du milieu de stockage de chaleur dans le magasin de chaleur (9) et dans la chambre la plus froide (11), puis on le fait revenir vers le dispositif de chauffage (13, 14, 15). Lorsque le fluide circule au travers du magasin de chaleur (9) dans cette direction, la direction de stockage de chaleur, le milieu de stockage de chaleur absorbe de la chaleur du fluide calorifere. Selon ce procede, le systeme de chauffage comprend une autre conduite de fluide calorifere qui relie les deux chambres (10, 11) a l"espace (20) qui doit etre chauffe. A l"aide d"un ventilateur ou d"un element de pompage, on fait circuler le fluide calorifere de la chambre la plus chaude (10) via l"espace (20) sur la chambre froide (11) et au travers du milieu de stockage de chaleur dans le magasin de chaleur (9) dans une direction, la direction de soutirage de chaleur, qui est opposee a ladite section de stockage de chaleur, le fluide absorbant de la chaleur du milieu de stockage de chaleur.
