摘要:
为实现防寒服保暖性能的动态调节,研发了以空气为保暖材料的Mountain充气夹克,采用外置手动按压充气泵连续改变充气量及其保暖性能。基于暖体假人实验,在不同充气量、有无袖子、是否穿抓绒衣3种实验条件下测试了充气夹克的局部热阻和总热阻,对比了NuDown充气夹克的隔热性能。实验结果表明:充气状态下的局部热阻和总热阻明显高于未充气状态,充气量会显著影响热阻,充气量越大服装热阻越高,且Moutain充气夹克在充气状态下比NuDown充气夹克具有更佳的保暖调节能力;有袖子时的局部热阻和总热阻明显高于无袖子状态,腹部和背部表现尤为明显;穿抓绒衣可有效增加服装系统热阻,但会很大程度地影响充气夹克的保暖调节能力。
