| Abstract: | This paper introduces the working principle of variable frequency technology; improves the calculation of efficiency and energy consumption for normal marine seawater pumps and constant-pressure variable-frequency seawater pump. A case Sea water cooling system is designed based on Class-20000TEU container vessel operating between Europe and Asia, containing central water cooling system and PID logic control system. By calculating costs between normal and variable frequency seawater pump, the accuracy of the method was verified. This method could be used to estimate the economic benefits for ships before the system is installed. |
