Abstract：
This article presents the types of closed-circuit cooling towers, the characteristics of outlet water temperature, as well as the system forms, temperature and accuracy control methods of closed-circuit cooling tower cooling water systems for large scientific facilities. Taking a certain large scientific facility project as an example, the system form and main equipment applied to typical process equipment are presented, in order to provide references for similar projects to adopt the closed-circuit cooling tower cooling technology.
