船舶中央冷却系统节能优化设计研究

现代船舶设计中，节能设计成为船舶设计成败的关键之一。为了降低船舶的燃油消耗，除通过优化船体线型减小船体阻力、增加桨径提高推进效率外，还可以通过对一些系统进行优化布置来实现一定的节能目的。以一型5万吨级散货系列船为例，利用功能关系转换的方法，通过表列比较其中央冷却系统改进前后对燃油消耗量的变化，证实了改进后的系统对燃油消耗量有所降低，从而说明通过对动力系统优化布置是可以达到一定的节能效果。

Research on the Design Optimization of Marine Central Air Conditioning System for Energy Saving

Energy saving performance is one of the crucial factors in terms of modem ship design. It is possible to reduce ship＇s fuel consumption by arrangement optimization for some systems, besides hull lines optimization to reduce hull resistance or increasing propeller diameter to improve propulsive efficiency. This study takes a 50k dwt bulk carrier as an example and compares the fuel consumption variation before and after central air-conditioning system optimization based on the power-energy transfer relation, which proves that the fuel consumption is reduced after system optimization and that it is possible to achieve energy saving through the arrangement optimization of power systems.
