Introduction介绍Shipboard ventilation systems supply and remove air to/from spaces throughout the ship. In doing so ,these systems contro

Theability of ventilation systems to protect personnel from these hazards is particularly important aboard ships, shich are like floating ci

18、ties fitted into a very limited apsce.Well designed and easily maintained ventilation systems are critical to a safe and comfortable shipboard work environment.装货通风系统为整艘船舶提供并注入空气。当启动那些系统的时候，那些系统提供大量的新鲜空气，从一些潜在的经过空气传播的污染物，比如火灾，爆炸和过多的热流中，保护全体船员和敏感货物。通风系统在船上从危险中保护船上全体成员的能力是非常重要的。这个就像一个漂浮的城市忽然间被装进一个非常狭窄

19、的空间里一样。好的设计和简单的维护通风系统决定了装货工作环境的安全和舒适程度。Ventilation systems include a supply, or makeup air system and an exhaust system. Supply systems replace contaminated air exhausted from a workspace with uncontaminated outside air. Supply ventilations systems also provide replenishment air to air conditioning

20、recirculation systems. Exhaust systems remove odors, heated air, and airborne contaminants from the workspace. Both supple and exhaust airflow quantities must be balanced.通风系统包括供给或者接通空气系统和为被污染的空气。供给系统从一个未被污染物污染的空气的场所，取代污染空气的排放。供给通风系统支持补充空气给空调循环系统，排气系统能消除工作场所异味，排除热空气，排除污染物。供给和排放对空气流动的工程量必须平衡。All comp

21、onents of ventilation systems such an fans, motors, ducts, dampers, air intakes and outlets, filters, and access panels, must work properly in order for the systems to operate safely and efficiently, Therefore, ventilation system design must be considered an essential part of planning, development,

22、and production of new shipboard equipment and systems and the facilities needed for their support. Not only must the systems themselves operate properly, but the way in which the operator and maintained fit into the design, or human systems integration, must also be taken into account. Failure to pr

23、ovide effective ventilation systems in the design stag can create costly obstacles to safe and efficient ship operation and maintenance, which ultimately presents a threat to personnel safety and health.为了是系统安全和有效的工作，所有的通风系统的部件，例如风扇，马达，管道，气阀，空气吸入和排除，过滤器检修门都应该前挡工作，因此，通风系统的设计必须被看作是计划，发展，新船舷设备制作以及系统和需要

24、他们支持的设施的必须的一部分。不仅系统自身的恰当操作，并且适合设计的操纵和维持的方式以及人工系统整合，都应该是考虑的因素，在设计阶段未能成功提供有效的通风系统，会对安全和有效的船舶操纵和维护产生高昂障碍代价，因此对个人安全和健康呈现威胁。2. Ventalation design and maintenance problems in laundries and galleysAboard ships, a great deal of actively involving complex equipment makes place in a relatively small space usi

25、ng large amounts of energy, A by-product of energy is heat. The most widespread ventilation problem aboard ship is controlling heat humidity produced by the cleaning and cooking processes in laundries and galleys. the build-up dirt, grease, and oil in the ducts serving these spaces, will restrict ai

26、rflow and reduce exhaust and supply air flow capabilities. Restricted air exhaust and supply will result in elevated temperatures, High heat and humidity lead to heat stress conditions that are both uncomfortable and reduce personnel productivity. In extreme cases, uncontrolled heat stress will expo

27、se personnel to the possibility of heat-related illnesses like heat exhaustion and heat stroke. Under certain conditions, personnel must be allowed time in a cooler environment to recover physiologically from the effects of heat stress. This has an indirect, but potentially very significant effect o

28、n cost over the life of the ship, because of reduced productivity and the need for additional manpower to perform a given set of tasks.登船时大量关于复杂设备的活动发生在相对较小的空间，这些活动要消耗大量能量。发热是能量消耗的副作用，在船上通风产生最普遍的问题是控制由在洗衣房和厨房进行的清洁和烹饪产生的热量和湿度。在接触上述地方的甲板上，逐渐增加的污垢，油脂和油，将会限制空气流动，减少废弃排除和供空气流通的能力。高温和高湿度所导致的热压力状况，使人感到不舒服并降

29、低个人的劳动效率。在极度事件中，未得到控制的热压力将使人暴露在可能与热量相关的疾病下，如：中暑衰竭。在通常情况下，一个人为了从热压力影响下恢复生理作用，必须允许有足够的呆在阴凉环境下的时间。这对于船舶的寿命有间接的作用，但却是潜在的并对花费具有重要影响，因为这降低了劳动生产率和为了完成给定任务所需要的额外劳动力。Another common ventilation problem associated with shipboard laundries and galleys is that airborne materials can collect in ducts unless a goo

30、d pre-filtration system is available and effectively maintained. Large volumes of lint generated in laundries can partially obstruct airflow and serve as potential combustion sources. Grease and other cooking residues generated in galleys that collect in ducts can also become combustible, Ventilatio

31、n duct fires are extremely difficult to extinguish. 另一个几点相关的通风问题是除非有一个很好的可利用的且直接有效的过滤系统，船上洗衣房和厨房经空气传播的物质才可以收集到管理里。洗衣房里大容积的麻布由于部分地被阻隔了空气流通会成为潜在的燃烧源头。厨房里被收集到的管道的油脂和另外一些剩下的食物也有可能成为燃烧物，通风管道里的火灾非常难以扑灭。3. Ventilation and maintenance problems in hazardous material storerooms and workshopsPoorly maintained

32、shipboard ventilation systems will result in dirty aid-filters that exceed design pressure drops, clogged ductwork, and low airflow. This can be particularly dangerous in shipboard hazardous material storerooms and in workshops that use hazardous materials. Inadequate ventilation can result in build-up of potentially hazardous levels of contaminants such as paint solvents. In extreme cases, control below fire-safety levels may be jeopardized, particularly after a hazardous material spill.保养不善的船上通风系统将导致脏的空气过滤（超过设计的眼里落尘，阻塞管道，和低的空气通过量）。在船上物料间或在工作间使用危险物料将尤为危险，不恰当的通风系统将导致增加潜在污染物危险水平，例如油漆，在极端
