开放式局部热阻测试系统的实现

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/m², and the local resistance error can be conrolled within 3.1%.
