摘　　要：为研究乘员舱内不同气流组织下的人体热舒适性,找出进气参数对人体热舒适性影响的规律,将Fluent计算得到的9种进气方案的流场结果作为环境参数导入TAITherm中进行热舒适性分析。同时引入面部平均空气龄和能量利用率两项指标对乘员舱气流组织进行更全面的评价。结果表明进气总量对3位乘员热舒适性和平均面部空气龄影响程度最大,1号口进气温度对能量利用率的影响程度最大。综合考虑3位乘员的热舒适性、面部平均空气龄和能量利用率3项评价指标,发现当进气总量为1800 kg/h,1、2号口进气温度都为22℃,1、2号口进气量比值为6∶4时3项指标均表现良好,为最优的进气参数组合。In order to study the thermal comfort of human body under different air distribution in the crew cabin and find out a law of influence of intake parameters on human thermal comfort,taking the flow field results with nine intake schemes being calculated and imported into TAITherm as environmental parameters,the thermal comfort analysis is made.At the same time,two indexes of mean facial air age and energy utilization are introduced to evaluate the air distribution in the crew compartment more comprehensively.The results show that the total amount of air intake has the greatest effect on the thermal comfort and average facial air age of the three occupants,and the inlet temperature of No.1 port has the greatest effect on the energy utilization rate.In consideration of the three evaluation indexes in thermal comfort,facial average air age and energy utilization of the three occupants,it is found that the three indexes perform well and the combination of inlet air parametersis the optimal when the total air intake is 1800 kg/h,the inlet temperatures of No.1 and No.2 are both at 22℃,and the inlet air ratio of No.1 and No.2 is 6∶4.
