一、空调送风量和送风参数的确定 1.舱室的显热负荷和湿负荷单位时间内渗入舱室并能引起室温变化的热量称为舱室的显热负荷,单位为kJ/h,用Q。表示。它主要包括:

一、船舶空调系统的分类 集中式和半集中式船舶空调装置根据其调节方法的不同主要有以下几种形式。 1.集中式单风管系统 2.区域再热式单风管系统 3.末端再处理式单风管系统 4.双风管系统

为了能在舱室内创造出一个适宜的 人工气候,以便为船员、旅客提供一个 舒适的工作和生活环境,现代船舶大都 设有空气调节装置

一、降温工况的自动调节 二、取暖工况的温度自动调节 三、取暖工况的湿度度自动调节 四、送风系统静压的自动调节

一锅炉在船舶动力装置中的作用 在蒸汽轮机动力装置的船舶上:锅炉产生的高温高压过热蒸汽用驱动主蒸 汽机,以推动船舶前进,这种锅炉称为主锅炉。 在柴油机动力装置的船舶上:锅炉产生的饱和蒸汽仅用于驱动蒸汽机、加 热燃油、滑油及满足日常生活的需要,这种锅炉称为辅锅炉

Provide for data logging, remote control and automatic action-pneumatic electro￾pneumatic, and electronic equipment, self￾regulating apparatus, etc. The chapter will give a general instruction above system and function. The other chapters of the book focus on the oil handling devices onboard

In motorships there are two main circuits, one salt , one fresh. The salt circuit is: sea inlet box (seachest) - pump(s) - f.w. coolers in series (first LT then HT) – turbo blower aftercoolers in parallel (if any) – provision condenser in parallel (if any) - overboard

Air at high pressure, i.e. at 25 bar or more, is required for starting main and auxiliary engines in motorships. Air at low pressure, say at 6 bar or less is required for much remote or temperature or pressure controlled equipment, for which purpose it must be clean and oil-free

Open systems using gravity tanks, etc., are rarely met nowadays and Figure 1.8 shows a characteristic arrangement of pressure tanks, calorifiers and pumps for a large ship. The fresh water pumps are self-priming, drawing from storage tanks and discharging through filters to a rising main, branched to give a cold supply and a hot supply in closed circuit through a calorifier. A tank kept under pressure by an external supply of compressed air rests on the system and provides the head necessary
