摘　　要：以某型客船的公共餐厅为研究对象,采用计算流体力学(CFD)方法对几种不同的送风末端方案进行数值模拟分析,包括圆形散流器、方形散流器和孔板天花板,从温度场分布、空气流动速度场分布、PMV及PDD指标和室内空气龄等指标角度对3种不同方案的模拟结果进行分析比较。结果表明:不同的送风末端型式对该公共处所内的空调送风效果有显著影响,其中,孔板天花板送风末端方案的室内空气质量和热舒适度水平高于其他方案。Taking the mess room of a passenger ship as the study object, several types of air diffuser schemes, including circular diffuser, square diffuser and perforated ceiling air diffuser, are simulated and investigated by the computational fluid dynamics（CFD） method. The temperature distribution, air flow velocity distribution, PMV, PPD and indoor mean age of air is employed to evaluate the performance of the 3 types of diffuser schemes. The results indicate that the type of air diffuser has a significant influence on the air distribution condition of the air conditioning system, in which the perforated ceiling air diffuser has a better performance on the thermal comfort and indoor air quality level for the space.
