摘　　要：为了实现节能减排的目的,船舶在各个系统上都积极寻求优化设计,最大限度地实现节能。根据不同工况下主机运行的台数及负荷的大小对机舱通风系统进行优化设计,以达到节能的效果。通过在机舱中安装压差和温度传感器实时监控机舱状态并将信号反馈给中控系统;中控系统将信号值与系统设定值进行对比,输出相关命令给风机变频器,以实现对风机的启停及速度的调节。通过实船验证可知,风机可以根据环境反馈信号实现自动调节启停及风速大小,机舱通风系统在智能化及节能方面实现了优化。此种设计可为船舶机舱通风系统的智能优化设计提供参考。In order to achieve the purpose of energy saving and emission reduction,the ship actively seeks to optimize the design of each system to maximize energy saving.According to the number of main engines running under different working conditions and the size of the load,the ventilation system is optimized to achieve the effect of energy saving.By installing differential pressure transmitters and temperature sensors in the engine room to monitor the status of the engine room and feed signals back to the central control system,which compares the signal value with the system set value and outputs relevant commands to the fan frequency converter to realize the starting and stopping of the fan and the adjustment of the speed.Through the verification of the real ship,the fan can automatically adjust the start-stop and fan speed according to the environmental feedback signal,and the ventilation system has been optimized in terms of intelligence and energy saving.This design can provide a reference for the intelligent optimization design of marine engine room ventilation system.
