摘要
从服装舒适性角度出发,以服装热舒适性的研究为入口,着重分析风速与步速对服装表面空气层热阻的影响,给出服装的热阻与风速及步速的关系公式。在设定的环境条件下,通过人体假人进行测试,验证公式的预测性和实用性,并找出裸态人体表面空气层热阻和着装后服装表面空气层热阻之间的差异。服装的热阻,以服装的表面为分界线,分为基本热阻与着装人体服装外表面边界空气层的热阻。实验结果表明:风速、行走速度会使服装外表面空气层的热阻减小。
Starting form the viewpoint of the comfort of a garment, this paper analyses the relationship between speed of wind and clothing thermal insulation. It gives the formulae about the relationship between both wind speed and walk speed and clothing thermal insulation under the controllable circumstance conditions and uses a manikin to test in order to validate that the formulae present are useable. The differences of surface air insulation between the manikin with clothing and that without clothing are determined. Clothing thermal insulation includes intrinsic thermal clothing insulation and surface air insulation. The experiment shows that the speed of wind and/or walk can make the resistance of the air layer next to the outer surface of the clothing decrease.
