摘要

中央海水冷却系统的优化设计是船舶节能减排的重要手段之一。结合中央冷却系统的工作方案，建立了系统数学模型，利用ISIGHT软件建立了系统仿真和优化环境。为了满足更高的船舶能耗标准，在系统设计中采用了变频技术。通过动态仿真，对不同频率控制方案进行了比较和分析。通过船舶精算实验结果验证了仿真模型的准确性。单船仿真结果表明:变频海水泵能全面降低能耗，显著提高工作负荷变化大、频繁的多用途船舶的经济性;为了实现最大的节能，必须根据不同的系统配置确定优化的频率控制策略。

Study on optimize design of central cooling system

Optimize design of central sea water cooling system is one of crucial means on ship energy-saving and emission reduction. Accompany with the working scheme of central cooling system, a system mathematic model was established, simulation and optimization environment was established with ISIGHT. In order to meet higher ship energy standard, variable frequency technology was applied in system design. By means of dynamic simulation, different frequency control scheme were compared and analysis. The veracity of simulation model was confirmed with the actuarial ship experiment result. The results of one ship simulation show that: variable frequency sea water pumps can comprehensively decrease energy consumption, and dramatically improve economic performance of multi-purpose ship, which working load greatly and frequently change; for maximal energy-saving, optimized frequency control strategy must be confirmed according to different system configuration.
