Abstract (en)
[origin: ES8608085A1] A refrigerant liquid flows through congelation probes (S1, S2, . . . ). The temperature of the liquid supplied to each probe is regulated as a function of the rate of congelation of the ground around the various probes and/or is progressively increased as the congelation progresses.
Abstract (fr)
Les sondes de congélation (S1, S2, ... ) sont parcourues par un liquide réfrigérant. La température du liquide envoyé dans chaque sonde est régulée en fonction de la vitesse de congélation du sol autour des différentes sondes et/ou est augmentée progressivement au fur et à mesure de la progression de la congélation.
