Cooling systems Heat from diesel engine and auxiliary units is directly or indirectly dissipated to sea water. Exceptions are exhaust gas and radiation. Temperature control is important • Wide variation of the cooling energy demand. • Wide variation of sea water temperature • Engine sensitivity to temperature deviations • Preferably independent systems for ME’s (2x) and AE’s for simple adjustment Water flow can be prevented by air pockets, ice slush or entered material. Chemical purity is important LT Cooling Systems
