淋雨及不同温度条件对消防员防护服各部位热阻的影响

Effects of rain and different temperature conditions on thermal resistance of various parts of firefighters’ protective clothing

为了研究淋雨及不同温度条件对消防员防护服各部位热阻的影响,以消防防护服为研究对象,利用环境舱和暖体假人系统,在20 mm/h降雨强度和20~30℃的复合环境条件下,研究淋雨、不同温度复合环境对服装各部位热阻的影响。研究结果表明:淋雨过程中,服装热阻的变化趋势为先上升再下降最后趋于稳定;淋雨与不同温度复合环境会使得消防防护服热阻降低,其中影响较大的部位为上臂部、腹部、胸部、背部及臀部等。

In order to study the influence of combined raining and different temperature conditions on the thermal resistance of various parts of firefighters’protective clothing,the fire-fighting protection clothing was used as the research object,through using the environmental chamber and the thermal manikin system,The effects of rain and different temperature composite environment on the thermal resistance of various parts of the clothing were studied under the combined environmental conditions of rainfall intensity as 20 mm/h and ambient temperature as 20-30℃.The results showed that during the raining process,the change trend of clothing thermal resistance increased first and then decreased and finally tended to be stable.The combined raining and different temperature environment would reduce the thermal resistance of fire-fighting protective clothing,and the most influential parts were the upper arm,stomach,chest,back and hip,etc.
