<p>Method for storing a coolant fluid (1) comprising two phases (1a, 1b) of one and the same substance in melting equilibrium, according to which the said fluid is arranged in a storage enclosure (2), in which the coolant fluid stored settles into a liquid lower layer (1b) and a solid upper layer (1a), the coolant fluid to be stored is introduced (3) into the enclosure (2) at the level of the lower layer (1b) and the coolant fluid to be removed from storage is extracted (4) from the enclosure at the level of the upper layer (1a), characterised in that, in combination, on the one hand, a gaseous atmosphere (6) is established between the upper layer (1a) and the upper wall of the enclosure (2) and, on the other hand, the coolant fluid to be removed from storage is extracted from a withdrawal zone (8) located at the level of the interface between the upper layer (1a) and the gaseous atmosphere (6) by a vertical flow (7), with generation of a vortex. <IMAGE></p> |
