船舶冷却系统的分析及其优化

EXERGY ANALYSIS AND OPTIMIZATION OF THE MARINE COOLING SYSTEM

船舶冷却系统是由各种换热器、管路和泵组成,用海水作为冷却介质的。本文从热力学角度对船舶冷却系统进行分析,找出正确评价其性能的热力学指标,并据此对柴油机船的中央冷却系统(图1)进行焖分析,找出改进的主要途径。 一、评价船舶冷却系统性能的热力学指标 如图2示,把船舶冷却系统取为热力学系统。

In this paper study is made of the marine cooling system from the point of view of thermodynamics and correct evaluation of its thermodynamical performance is established. And then on this basis, exergy analysis is made of the motor ship centralized cooling system and the primary methods are presented for improving the system.
