环境温湿度及风速对消防服热舒适属性影响的定量研究

为量化环境条件对消防服热舒适性能的影响，选取我国02式消防服，测量其在不同环境温度、湿度及风速条件下的热阻和湿阻并得出拟合公式；通过回归分析法分析环境条件对热阻和湿阻的影响，提出其对热阻和湿阻影响的数学模型。结果表明:风速对热阻和湿阻的影响较大，而环境温度和湿度对热阻及湿阻的影响较少；风速与整体热阻及整体湿阻呈负相关，而风速与固有热阻和固有湿阻呈正相关。该研究可为消防服热舒适性能测试及高性能防护装备研发提供理论指导。

Quantitative study on influence of ambient temperature,humidity,and wind speed on thermal comfort properties of protective clothing for firefighting

In order to quantify the influence of ambient conditions on the thermal comfort properties of protective clothing for firefighting,the ‘02’ type protective clothing for firefighting was selected to measure the thermal resistance and evaporative resistance under different temperatures,humidity and wind speeds and obtain the fitting formulas.Then,the influence of ambient conditions on the thermal resistance and evaporative resistance were analyzed through the regression,and a mathematical model for the influence of ambient conditions on the thermal resistance and evaporative resistance was put forward.The results showed that the wind speed had great influence on the thermal resistance and evaporative resistance,while the ambient temperature and humidity had less influence on the thermal resistance and evaporative resistance.The wind speed presented the negative correlation with the total thermal resistance and total evaporative resistance,while it presented the positive correlation with the intrinsic thermal resistance and intrinsic evaporative resistance.The results can provide theoretical guidance for the tests on the thermal comfort properties of protective clothing for firefighting and the research and development of high performance protective equipments.
