Antifreeze cooling subsystem

摘要: Liquid cooled systems having coolant circulation loops (136) must often operate in below freezing conditions. For instance, various applications certain fuel cell (10) be able to tolerate repeated shutdown and storage Conventional glycol-based coolants typically used for internal combustion engines are generally unsuitable use the associated cooling subsystems due presence of additives and/or inhibitors which normally included deal with problems relating decomposition glycol. With or present, conductivity can sufficiently high as result electrical shorting corrosion problems. However, provided purity is maintained, a pure glycol water mixture may system obtain suitable antifreeze protection. Adequate maintained by including an ion exchange resin unit (158) subsystem.
