摘要
采用自主研发的导热系数测试装置及方法,得到了防寒服填充絮料厚度与导热系数间的试验关系.利用多层服装隔热值分配规律,推导了防寒服内胆材料工程厚度与隔热值之间的关系,并最终建立了絮料面密度与其隔热值之间的关系式.根据人体的代谢产热率及国标中有关保持人体热舒适的标准,提出了一种快速简易获得不同温度下保持人体热舒适所需防寒服内胆材料最佳面密度的方法.
By the self-developed coefficient of thermal conductivity test devices and test method,the experimental relationship between the thickness of wadding used in cold protective clothing and its thermal conductivity was acquired.According to the distribution laws of a multi-layers clothing ensemble,the relationship between the engineering thickness of wadding and its heat resistance was obtained.Finally,the formula between the surface density of wadding and its heat resistance was established.A quick and easy method for determining the surface density of wadding under different temperatures to maintain human thermal comfort was proposed,which was considered on the human body metabolic heat production rate and the national standards about maintaining human thermal comfort.
