摘　　要：文章通过对现有船舶冷却系统的现状分析,着重介绍了船舶冷却水泵变频节能原理及系统控制方案。对现有船舶海、淡水冷却水泵分别进行变频节能改造,实现降低使用功率的目的。与改造前的航行、停泊工况比较,结果表明:改造后的冷却水泵节能效果显著,经济效益和社会效益明显。Through analyzing the current situation of marine cooling systems,this paper expounds the energy saving principle of frequency conversion of marine cooling pumps and the system control scheme.Frequency conversion transformation for energy saving is carried out on both marine seawater cooling pumps and freshwater cooling pumps to reduce the service power.A comparison with the sailing and berthing conditions before transformation is conducted.The results show that the energy saving effects of the cooling pumps after transformations are remarkable and the economic,and social benefits are obvious.
