The Authors, of Alfa-Laval S.A., introduce the article with some general information on central cooling systems, in engine rooms, covering main and auxiliary machinery, air conditioning, refrigeration plant, and other shipboard cooling requirements, and describe, with diagrams, some basic central systems, both with and without connections between the low- and high-temperature circuits in the fresh-water section. A description is then given of a comprehensive central cooling-system designed for medium-size multi-purpose cargo ships with a 14,000-bhp low-speed main engine. The system, which has a single closed fresh-water circuit, is shown diagrammatically, together with dimensioned drawings of the two central coolers, which are of the titanium plate-type, and a detailed heat-balance table. There are three separate plate-type coolers for, respectively, the main-engine jackets, lubricating oil, and piston water. This particular system, and the advantages of central cooling systems in general, are discussed, and it is concluded that, though the coolers have a high initial cost, such systems reduce maintenance costs significantly, increase availability, and save man-power. There are now over 200 ships with central cooling systems. Order from: BSRA as No. 47,793.
