Abstract

L'invention concerne un procédé permettant de mettre à disposition de l'eau de lac et/ou de l'eau de mer, l'un ou l'autre type d'eau s'utilisant de préférence comme substance réfrigérante ou chauffante pour les processus les plus divers. Selon l'invention, l'eau de lac et/ou l'eau de mer sont pompées selon le principe du siphon et mises à disposition. Le dispositif mis au point selon l'invention comprend a) au moins une conduite de prélèvement d'eau de lac et/ou d'eau de mer (1, 2), dont l'orifice d'entrée se trouve à une profondeur h 3 en dessous du niveau du lac ou de la mer, dont le point le plus élevé se trouve à une profondeur h 1 en dessous du niveau du lac ou de la mer, h 1 étant < h 2 < h 3; b) au moins un bassin dans lequel débouche la conduite de prélèvement d'eau de lac et/ou d'eau de mer, et c) des éléments pour ajuster le niveau de l'eau dans le bassin.
