ABSTRACT:
A system for cooling hydrogen which is used for cooling an electric power generator, cooling of the hydrogen being effected by transfer of heat from hydrogen leaving the generator to cooling water extracted from a source which has a temperature determined by external conditions. The system is composed of an indirect heat exchanger for bringing cooling water into heat exchange communication with hydrogen leaving the generator and cooling water is supplied to the heat exchanger partially from the source and partially from cooling water leaving the heat exchanger. A temperature monitoring unit produces an indication of the temperature of the cooling water extracted from the source and a control unit is coupled to the temperature monitoring unit to cool the hydrogen to a desired temperature while maintaining a constant flow rate of cooling water into the heat exchanger.
