同程式空调水系统的实船设计应用

分析了空调水系统阻力的特点和水力不平衡的原因,并对同程和异程两种空调水系统管路设计方式的优缺点进行了比较。结合某两型船舶的总体布局和空调区域特点,分别采用环形同程冷热媒水系统和开式同程冷却水系统,显著提高了系统水力稳定性,取得较好的空调效果。

Practical design and application of water system in reverse return air conditioning water system

This paper analyzes the characteristics of water resistance and the reasons of the hydraulic imbalance in air conditioning system,and compares the advantages and disadvantages of pipeline design for the reverse return and direct return air conditioning water system.Considered the overall layout and the air-conditioning area characteristics of the two ships,a circular reverse return of the chilled（heat） water system and an open reverse return of the cooling water system have been adopted respectively,which obviously improve the hydraulic stability of the system to gain the better air conditioning effect.
