摘　　要：空气层热湿传递机制的研究不仅可为更加准确的实验室热防护性能测试提供指导,也可提高消防服热湿传递数值模拟的精确度。在阐述了热防护性能测试中空气层的作用以及空气层热传递机制和空气层热传递模型的研究现状的基础上,分析了服装与人体之间空气层微气候的特征,从热传导、对流换热和辐射换热3个方面总结了空气层的热传递机制,提出不同条件下空气层传热模型建立的基本思路,并对未来消防服衣下空气层热传递机制的研究动向作出了预测。Research of heat transfer mechanism of air gap can not only provide a guideline for more accurate test on thermal protective performance,but also improve the precision of numerical simulation about heat and moisture transfer model. Based on the role of air gap in thermal protective performance test and the research status of heat transfer models of air gap,the features of air gap between clothing and body are analyzed. And heat transfer mechanism of air gap is summarized in terms of heat conduction,convective heat transfer and radiative heat transfer. Modeling heat transfer of air gap is proposed under different exposure conditions,and predicting future direction in the study on heat transfer model of air gap between protective clothing and skin surface.
