柴油机船舶机舱通风设计中若干问题探讨

Discussion on ventilation design of engine room on ships using diesel engines

优良的机舱通风设计是保证机舱内设备正常运行和船员舒适的前提。文章归纳总结多个项目机舱通风系统设计中船东和船检经常提出的几个问题:船东侧重于总风量的计算、风管布置和风量的分配;船检则注重系统的安全性,如防火要求和风管布置不能影响机舱水雾系统等。文中分别就各个问题进行较详尽的分析与讨论,可为相关设计人员解决实际问题提供借鉴。

Excellent ventilation design of engine room can ensure the normal operation of the equipment and the comfort of the crew.This article summarizes several questions often presented by ship owners and classification societies in the ventilation design of the engine room.The ship owners mainly focus on the total air capacity calculation,the air duct arrangement and the air flow distribution,while the classification societies mainly concerns the system safety,such as the fire protection requirements and the air duct arrangement without affecting the water mist system of the engine room.Each problem is analyzed and discussed thoroughly,which can provide reference for the relevant designers.
