摘　　要：针对目前适用于单段暖体假人局部热阻测试系统较少的问题,结合康奈尔大学的单段暖体假人(Walter出汗暖体假人)系统,设计搭建了开放式局部热阻测试系统并进行了局部热舒适性研究。采用该系统对Walter出汗暖体假人的裸态和穿M号全棉衬衣和休闲裤、穿大孔M号全棉短袖衫和休闲裤、穿小孔M号全棉短袖衫和休闲裤、穿全棉T恤和休闲裤等4种着装状态下共5种情况进行了整体热流密度、局部热流密度和服装热阻3项测试。结果表明,开放式局部热阻测试系统可准确表示穿着不同服装条件下假人的局部热流密度数值,其整体热流密度误差不超过4.6 W/m2,热阻误差不超过3.1%。In view of very few tests on local thermal insulation using″Whole-segment″thermal manikin,with″Whole-segment″(″Walter″sweating manikin)in Cornell University,the open local thermal resistance test system was designed and developed,and related research was carried out.By several instances including nude state and wearing M type cotton shirt+trouser state,wearing M type cotton short sleeve shirt(large hole)+trouser state,wearing M type cotton short sleeve shirt(small hole)+trouser state,wearing M type cotton T-shirt+trouser state,whole body heat flux test,local heat flux test and local thermal resistance test were completed with this system.The results show that the open local thermal resistance test system can accurately represent the local heat flux value of the manikin under different clothing conditions,the overall heat loss tested does not exceed 4.6 W/m 2,and the local resistance error can be conrolled within 3.1%.
