Sea Water Coooling System Line Diagram…….. The machinery systems fitted on board ships are designed to work with maximum efficiency and run for long hours. The most common and maximum energy loss from machinery is in the form of heat energy. This loss of heat energy has to be reduced or carried away by a cooling media, such as central cooling water system, to avoid malfunctioning or breakdown of the machinery.
The sea water is used as a cooling media in large seawater cooled heat exchangers to cool the fresh water of the closed circuit. They are the central coolers of the system and are normally installed in a duplex.
