Circulating water cooling system and method for inhibiting corrosion of circulating water cooling system

摘要

PROBLEM TO BE SOLVED: To provide a circulation water type cooling facility capable of suppressing corrosion in a heat exchanger of a high load device, and a corrosion suppression method of the circulation water type cooling facility.SOLUTION: A circulation water type cooling facility includes a cooled device group cooled with cooling water, and a first cooler configured to cool cooling water returned from the cooled device group and then supply it to the cooled device group. In at least a part of the cooled device group, included is a high head load device where indirect cooling is performed through a heat exchanger between cooling water and a cooled device, and where a water temperature of cooling water after heat exchange becomes high. At a rear stage of the first cooler and at a front stage of the high heat load device, included is a second cooler configured to cool cooling water supplied to at least the high heat load device.SELECTED DRAWING: Figure 1
