摘要/Abstract

摘要： 为定量研究防刺服(SRBA)的热湿传递性能,改善防刺服的热舒适,采用暖体假人试验测量分析不同温度(25、30和40 ℃)和湿度(40%,55%,70%)下,降温服、防刺服以及两者叠穿时的热阻和湿阻及其变化特征。发现3个温度下3种着装的热阻变化为防刺服＞降温服与防刺服叠穿＞降温服,湿阻则在30 ℃以上遵循这一特征。温度越高,降温服对防刺服的传热效率影响越大,热阻最高可降低46.75%,湿阻最高可降低82.97%。结果表明:在较高环境温度下(30 ℃以上),降温服可有效降低防刺服的热阻和湿阻,提高防刺服的热湿传递效率。降温服对防刺服的热湿传递影响特征随环境温度、湿度和设计特性而改变。

Abstract: In order to quantitatively study the heat and moisture transfer performance of SRBA and improve the thermal comfort of SRBA, a thermal manikin was used to measure and analyze thermal insulation and evaporative resistance of cooling vest, SRBA and both stacks at different temperatures (25, 30, 40 ℃) and humidity (40%, 55%, 70%). It is found that the thermal insulation changes at the three temperatures measured as SRBA> both stacks > cooling vest, and the evaporative resistance follows this characteristic above 30 ℃, that the higher the temperature is, the greater the effect of the cooling vest on the heat transfer efficiency of the SRBA will be, and that the thermal insulation can be reduced by up to 46.75% and the evaporative resistance can be reduced up to 82.97%. The results show that at higher ambient temperature (＞30 ℃), the cooling vest can effectively reduce the thermal insulation and evaporative resistance of the SRBA and improve the heat and moisture transfer efficiency, and that the influence of the cooling vest on the heat and moisture transfer of the SRBA changes with the ambient temperature, humidity and design characteristics.

Key words: cooling vest, stab-resistant body armor (SRBA), thermal insulation, evaporative resistance, thermal manikin
