摘　　要：为准确评价船舶舱室污染物传播情况,本文以某船舶舱室为研究对象,利用多区域网络模型,研究不同通风空调工况下新风量和局部净化设备对舱室污染物分布的影响。结果表明:合理配置局部净化设备,可有效降低高污染区域和相邻区域内的污染物浓度;新风量大小与污染物浓度水平之间存在着一个合理的匹配值,该成果可为评价和改进船舶舱室的空调系统设计提供指导。For accurate evaluation of contaminant transport in ship cabins, this paper has studied the influence of fresh air volume and local cleaning device in the contaminant distribution within a ship cabin using a multi-zone network model under different conditions. The result shows that reasonable configuration of purification equipment can effectively lower the contaminant concentration in the highly contaminanted zone and the adjacent zones, and there is a reasonable match between the fresh air volume and contaminant concentration, which provides a design guide for further assessing and improving the ship cabin airconditioning system.
