Abstract

L'invention porte sur un dispositif de climatisation, dans lequel dispositif un élément de tuyau enfoui dans le sol est utilisé. Cette invention a : l'élément de tuyau, à travers lequel de l'air pour la climatisation s'écoule le long de la direction de l'axe du tuyau ; un canal disposé sur la paroi de l'élément de tuyau, et formé de telle sorte que de l'eau s'écoule à partir d'une extrémité jusqu'à l'autre extrémité de l'élément de tuyau ; et un mécanisme de fourniture/évacuation d'eau pour fournir de l'eau au canal à partir de la première extrémité, et évacuer l'eau, qui s'est écoulée à travers le canal et qui a échangé de la chaleur avec l'air, à partir de l'autre extrémité.
