摘　　要：2017年对保存南海Ⅰ号沉船的“水晶宫”实施了封闭改造,加装玻璃罩。此后,饱水木质结构船体散发出的异味在玻璃罩内持续扩散难以排除,对于船体的永续保存、观众与工作人员的健康造成了威胁。本文运用采集环境数据、建立CFD模型、采用PMV-PPD热舒适评价指标分析等方法,对现有保存环境的通风系统、空气流动、污染物浓度分布等进行了比较研究,发现了问题及产生原因。并用CFD仿真模拟技术对“水晶宫”内通风系统的优化设计进行了初步探索,提出了调整送排风管、下拉回风管、优化通风调控值等改善措施,为南海Ⅰ号沉船保存环境的预防性保护提供了参考。In 2017,the Crystal Palace,which preserved the Nanhai I Shipwreck,was closed and retrofitted with a glass enclosure.Since then,the water-filled wooden structure of the ship’s body emitted by the smell of continued diffusion in the glass cover is difficult to rule out,for the ship’s sustainable preservation,the health of the audience and staff posed a threat.By collecting environmental data,establishing the CFD model and analyzing the index of thermal comfort evaluation of PMV-PPD,this paper makes a comparative study on the ventilation system,air flow and pollutant concentration distribution of the existing preservation environment,and points out the existing problems and causes.The CFD simulation technology is applied to explore the optimal design of the ventilation system in the Crystal Palace,and some improvement measures are put forward,such as adjusting the air supply and exhaust pipes,pulling down and returning pipes,optimizing the ventilation control value,etc.provides a reference for the preventive protection of the preservation environment of Nanhai I Shipwreck.
