Method for storing thermal energy in, and recapturing thermal energy from, respectively, an underground energy storage (1) , comprising at least four holes (2) , through which a heat carrier is transported and therewith heating or cooling the ground (3) , respectively. The invention is characterized in that the holes (2) are arranged essentially along at least two concentric circles (10, 11, 12) , in that a control gear is arranged to control a valve system, which is arranged to direct the heat carrier to holes that are arranged along one circle and thereby heating or cooling, respectively, the ground along said circle, in that when the temperature of the heat carrier is higher than that of the surrounding ground (3) , inner circles are heated before outer circles, and in that when the temperature of the heat carrier is lower than that of the surrounding ground (3) , outer circles are cooled before inner circles. The invention also relates to a device.
L'invention concerne un procédé de stockage d'énergie thermique dans, et de reprise d'énergie thermique depuis respectivement, un stockage (1) d'énergie souterrain, comprenant au moins quatre trous (2), au travers desquels un porteur de chaleur est transporté et en conséquence réchauffe ou refroidit le sol (3) respectivement. L'invention est caractérisée en ce que les trous (2) sont disposés sensiblement le long d'au moins deux cercles concentriques (10, 11, 12), en ce qu'un pignon de commande est prévu pour commander un système de vanne, qui est prévu pour diriger le porteur de chaleur vers des trous qui sont disposés le long d'un cercle, et ainsi chauffer ou refroidir respectivement, le sol le long dudit cercle, en ce que lorsque la température du porteur de chaleur est plus élevée que celle du sol (3) environnant, les cercles internes sont chauffés avant les cercles externes, et en ce que lorsque la température du porteur de chaleur est moins élevée que celle du sol (3) environnant, les cercles externes sont chauffés avant les cercles internes. L'invention concerne en outre un dispositif.
