Updated: 2020/9/16 22:06:39

Abstract: Based on the analysis of the current research and market status of the inflatable cold protective clothing, this paper discusses its existing problems in the ventilation design. First, the thermal insulation principle and three factors that affect the ventilation performance of the inflatable cold protective clothing were introduced. And then, based on the analysis of the applicability of the current ventilation design methods, the paper put forward related optimization scheme from fabric and garment, as well as the key issues of ventilation design based on the reasonable configuration of breathable fabric and clothing opening design. In the end, besides the influence factors of its ventilation performance, the ventilation design of the inflatable cold protective clothing should consider the characteristics of a multi-layer fabric system, the hermetic air layer in the middle, and the physiological characteristics of the human body. The reasonable configuration of the breathable fabrics of the inflatable cold protective clothing was clarified; the loose volume ratio between each layer, and the quantitative control of the opening size and position were elucidated, so as to meet the different heat dissipation requirements of the human body.
