2023年某地铁车辆客室送风道送风均匀性优化分析王常宇1单红娜2(1．中车长春轨道客车股份有限公司，130062，长春;2．长春市轨道交通集团有限公司，130022，长春∥第一作者，高级工程师)摘要针对某地铁车辆客室送风道结构，采用STAＲ-CCM+软件分析其送风均匀性。经计算发现，当采用初始送风道结构时，客室两端送风量较大，各段送风口的质量流量偏离整体送风口平均值较多，其相对误差的标准差也较大，客室送风均匀性较差。通过改变送风道结构和增加主风道内隔板等方法优化初始送风道结构，优化后各段送风口的质量流量更接近整体送风口平均值，其相对误差的标准差也有所减小，客室的送风均匀性获得了极大的提高。关键词地铁车辆;送风道;送风均匀性中图分类号U270．38+3DOI:10．16037/j．1007－869x．2023．01．047OptimizationAnalysisofCompartmentAirSupplyUniformityinAirDeliveryDuctofaMetroVehicleWANGChangyu，SHANHongnaAbstractTargetingtheairdeliveryductstructureofametrovehiclecompartment，theSTAＲ-CCM+softwareisusedtoan-alyzeitsairsupplyuniformity．Thecalculationresultsshowthatwhenadoptingtheinitialairdeliveryductstructure，theairvol-umeofbothendsofthecompartmentisrelativelylarger，themassflowdeviationofeachsectionalairsupplyoutletfromtheoverallaveragevalueisrelativelyhigher，andthestandardde-viationofrelativeerrorisalsorelativelylarger，sotheuniform-ityofcompartmentairsupplyisrelativelypoor．Bymethodssuchaschangingairdeliveryductstructureandaddingmainductinternalbaffle，theinitialairdeliveryductstructureisop-timized，andthemassflowofeachsectionalairsupplyoutletafteroptimizationbecomesclosertotheoverallaveragevalue，andthestandarddeviationofrelativeerrorisreduced，withtheuniformityofcompartmentairsupplybeingsignificantlyim-proved．Keywordsmetrovehicle;airsupplyduct;airsupplyuni-formityFirst-author'saddressCＲＲCChangchunＲailwayVehiclesCo．，Ltd．，130062，Changchun，China随着我国城市轨道交通的不断发展，对地铁车厢内乘客热舒适性的研究备受关注［1-2］。客室空调送风道良好的送风均匀性是决定乘客舒适性的重要指标，因此合理设计空调送风道成为了整个空调系统设计中较为重要的环节。文献［3］分析了带有静压腔式空调送风道的送风原理及结构，提出...
