基于暖体出汗假人的双层保暖内衣热舒适性研究

以男士双层保暖内衣为研究对象,使用暖体出汗假人同时测量了该内衣的热阻与湿阻,并使用三维人体扫描仪对其与暖体假人之间的空气层体积进行了测量,建立了空气层体积与保暖内衣热阻和湿阻之间的多项回归模型。结果显示,在内衣测量范围内,其热阻随着号型的增大先增加后减小,而湿阻则随着号型的增大逐渐增加。进一步研究发现,其透湿指数随着号型的增大逐渐减小,说明其热舒适性随着号型的增大而减弱。

An Investigation to the Thermal Comfort of Double-layer Thermal Underwear Based on Thermal Manikin

By taking men’s thermal underwear as example, the thermal resistance and moisture resistance of the underwear were measured by using a thermal manikin, the volume of the air layer between the thermal underwear and the thermal manikin was also measured with a 3D body scanner, and a multivariate regression model between the volume of the air layer and the thermal resistance and moisture resistance of the thermal underwear was built. The result shows that within the measurements of the underwear, the thermal resistance first increases and then decreases when the size increases, and the moisture resistance increases along with the increase of sizes. From further study it is found out that the moisture permeability decreases along with the increase of sizes, indicating the larger the sizes, the poorer the thermal comfort.
