Title
(EN) DEVICE AND METHOD FOR ENERGY WELL
(FR) DISPOSITIF ET PROCÉDÉ POUR PUITS D'ÉNERGIE
Abstract
(EN)
Method for increasing efficiency during heating or cooling using an energy well (1) in the form of an elongated hole the bottom of which is arranged at a greater depth than its opening, where a cooling agent streams through the well (1) in a collector conduit (3) and is heat exchanged against the material surrounding the well (1). The invention is characterised in that a tube (301) runs down into the energy well (1) from above its opening and down along the energy well (1) towards its bottom, in that the end (303) of the tube (301) facing towards the bottom of the energy well (1) is open, in that liquid is supplied through the tube (301) so that the liquid thereby streams down and out into the energy well (1) through the open end (303) of the tube (301), in that gas bubbles (305) are supplied to the liquid streaming down through the tube (301), and in that the added gas bubbles (305) are so small so that they rise more slowly in the liquid than the velocity of the liquid at the supply point.
(FR)
L'invention porte sur un procédé permettant d'augmenter le rendement durant le chauffage ou le refroidissement en utilisant un puits d'énergie (1) se présentant sous la forme d'un trou allongé dont le fond est disposé à une profondeur plus importante que son ouverture, un agent de refroidissement s'écoulant à travers le puits (1) dans une conduite de collecteur (3) et subissant un échange de chaleur avec le matériau entourant le puits (1). L'invention est caractérisée en ce qu'un tube (301) s'étend vers le bas dans le puits d'énergie (1) à partir d'au-dessus de son ouverture et vers le bas le long du puits d'énergie (1) vers son fond, en ce que l'extrémité (303) du tube (301) tournée vers le fond du puits d'énergie (1) est ouverte, en ce que du liquide est distribué à travers le tube (301) de telle sorte que le liquide s'écoule ainsi vers le bas et hors du tube pour rentrer dans le puits d'énergie (1) à travers l'extrémité ouverte (303) du tube (301), en ce que les bulles de gaz (305) sont distribuées au liquide s'écoulant vers le bas à travers le tube (301), et ce que les bulles de gaz ajoutées (305) sont si petites qu'elles s'élèvent plus lentement dans le liquide que la vitesse du liquide au niveau du point de distribution.
