Cooling arrangement and method of operating the same

摘要

The invention relates to a cooling arrangement, particularly for cooling electrical devices with water-cooled electric conductors, with deionized cooling water (deionate) and a closed cooling system which contains a parallel loop with a mixed-bed filter. According to the invention, the mixed-bed filter is preceded by an alkalizing cation exchanger and an anion exchanger in OH-form, and the mixed-bed filter is provided with a bypass. With this arrangement, the cooling water can be run in a higher pH-value range which for generators may preferentially be about 8 to 8.4.
