CENTRAL COOLING SYSTEMS FOR MARINE DIESEL ENGINE PLANTS
The paper covers problems involved in comparing conventional engine rooms in which all heat exchangers are cooled by sea water, with one where the sea water is replaced by a closed fresh water circuit, cooled by sea water in one or more heat exchangers called central coolers. Maintenance and running conditions are considered as are economical aspects, and details are given of such factors as water flow circuit diagrams for various systems, flow distribution, temperature levels, location of components, sizes, materials and installation costs for both the central coolers and secondary heat exchangers, aspects on the choice of materials for pumps, valves and pipes, and principles for regulation of water, oil and air temperatures. Practical operating experiences gained from shipowners and engine room staff in regard to the economical advantages and favourable running conditions for the main engines, including maintenance of pipings, valves, coolers and the engine room in general, are also presented.
