Supply circuit for a heat transfer medium for a consumer, industrial installation and method for operating same

An industrial installation comprising:

• a) a primary supply circuit, in which cooling water is conducted;
• b) a consumer, to which cooling water from the primary supply circuit is made available, and which is connected via a secondary supply circuit to the primary supply circuit for this purpose;
• c) an inflow line of the secondary supply circuit being connected to an inflow line of the primary supply circuit, and a return line of the secondary supply circuit being connected to a return line of the primary supply circuit;
• d) a circulation line connecting the return line of the secondary supply circuit to the inflow line of the secondary supply circuit, the circulation line being selectively openable and closable to provide a fluidic connection between the return line of the secondary supply circuit and the inflow line of the secondary supply circuit;
• wherein
• e) the inflow line of the primary supply circuit is connected to a groundwater conveying line of a well system which comprises a groundwater conveying device and by means of which groundwater can be conveyed out of an aquifer and by means of which this groundwater can be fed as cooling water into the inflow line of the primary supply circuit.
