服装面积因子的测评

利用暖体假人测定服装热阻时，考虑到着装后服装外表面积变大导致的边界空气层变化对服装的基本或固有热阻的影响，需引入服装面积因子的概念。本文首先阐述了服装面积因子的定义和应用：接着从直接法和间接法两大方法归纳现有测评服装面积因子的研究：最后对服装面积因子与热阻间的关系做了详细论述。

The Evaluation of Clothing Area Factor

While the heated manikin is needed in clothing insulation measurement, the surface area of a clothed body is larger than nude body, the increased surface will increase the dry heat transfer from the surface to the surrounding environment. Therefore, a correction by using clothing area factor is introduced. This paper describes the definition and application of clothing area factor, then clothing area factor evaluation from the two major direct and indirect methods are summarized, finally the relationship between clothing area factor and thermal resistance is given out.
