An improved heat transfer column for geothermal heating and cooling in which refrigerant lines are wound in a spiral fashion about a vertically oriented support. The spiral tubing is surrounded by a flexible, semi-flexible, or rigid liner which is filled with water, the liner being positioned within a cavity in an earth mass. During operation, water within the tube rises and/or by convection and transfers heat evenly to the water within the liner for subsequent transfer to the earth mass. This heat is subsequently extracted from or rejected into the earth mass during a heat transfer cycle, and means is provided for transfer of a portion of the heat in the water to the ambient atmosphere.
La présente invention concerne une colonne de transfert thermique améliorée pour le chauffage et le refroidissement géothermique dans laquelle des conduites de fluide de refroidissement sont enroulées en spirale autour d'un support orienté verticalement. Le tubage en spirale est entouré par un revêtement intérieur flexible, semi-flexible, ou rigide qui est rempli d'eau, le revêtement intérieur étant positionné à l'intérieur d'une cavité dans une masse terrestre. Lors de son fonctionnement, l'eau à l'intérieur du tube monte et/ou par convection assure un transfert uniforme de chaleur vers l'eau dans le revêtement intérieur pour un transfert ultérieur vers la masse terrestre. Cette chaleur est ultérieurement extraite depuis ou rejetée dans la masse terrestre lors d'un cycle de transfert thermique, et un moyen est prévu pour le transfert d'une partie de la chaleur dans l'eau vers l'atmosphère ambiante.
