A Study on the Control Solution of Ship’s Central Fresh Water Cooling System for Efficient Energy Control Based on Merchant Training Ship

Large ships adopt a central fresh water-cooling system that indirectly cools waste heat with seawater to discharge the ship′s out of ship. Such is essential for future electric powered ships. Since 2010, shipping companies have attempted save energy by applying variable-speed cooling pumps FW system, but due minimum-required pressure pump, they applied existing 3-way valve alongside. However, since control systems pump and are controlled same output variable, two collide during operation. Therefore, efficient energy-saving control, it important accurately model find optimal method on this basis. In study, ship’s was mathematically modeled verified comparing actual operation data. A solution effectively proposed
