摘要
大型客船通常配置多种厨房以保障不同乘客的需求,每个厨房都需配置1台或多台排风机,因此厨房需求的排风量非常大,对应的排风风机能耗也较高。厨房集气罩用于收集厨房里各类设备工作时产生的水蒸气和油烟,是厨房排风系统的重要组成部分,目前的大型客船厨房排风一般都采取集气罩进行集中局部排风。文中对大型客船厨房传统集气罩排风系统控制技术进行分析,针对其排风量大、能耗高的缺点,基于风机变频及变风量控制技术,提出了1种新型厨房集气罩节能排风控制系统的设计方法。通过在某客滚船上进行试验验证,对比分析传统排风系统与节能排风系统中厨房排风机的风量数据,验证了该新型厨房集气罩排风系统具有显著的节能效果,可在其他船型进行推广应用。
Large passenger ships usually have multiple galleys to meet the needs of different passengers for delicious food.And each galley demands to be equipped with one or more exhaust fans.The galley therefore requires high exhaust air volume,correspondingly with high energy consumption of the exhaust fan.The galley hood is an important component of the galley exhaust system,which is used to collect water vapor and oil smoke generated by various equipment in the galley.At present,the galley on large passenger ships generally uses the hood for centralized local ventilation.This study analyzes the control technology of the exhaust system of the traditional galley hood on large passenger ships.A new design method of energy-saving exhaust control system is proposed for the galley hood based on the frequency conversion control technology and variable air volume control technology for fans,in order to address the disadvantages of high exhaust air volume and high energy consumption.Through experimental verification on a Ro-ro passenger ship,the air volume data of the galley exhaust fan in the traditional exhaust system are compared and analyzed with those in the energy-saving exhaust system.It is verified that the new galley hood exhaust system has significant energy-saving effect and can be popularized in other ship types.
