摘要
消防员在执行危险化学品事故处置和灭火救援等任务时,长时间穿着密闭防护服或处于高温环境下作业的热负荷较大,甚至可能会出现中暑、热射病等热应激现象.本文选取典型液冷型与蓄冷型降温背心,开展35℃炎热环境下穿着气密型化学防护服的人体运动热生理反应试验研究,分析降温服的降温效果以及提高消防救援人员热舒适性方面的有效性.结果表明,与仅穿着化学防护服相比,蓄冷型与液冷型降温背心均可有效降低人体皮肤温度、核心温度、心率等,从而有效改善人体热舒适性,其中液冷型降温背心对热舒适效果改善更优.
Abstract
Firefighters have to handle dangerous situations such as hazardous chemical accidents,firefighting,and rescue operations.They often wear protective clothing for extended periods and work in high-temperature environments,which can lead to heat stress such as heatstroke and heat exhaustion.This study focuses on two personal cooling systems-liquid cooling garments(LCG)and phase change materials cooling vests(PCM),and conducts ex-perimental research on their effectiveness in reducing the thermal physiological response of human movement wearing airtight chemical protective clothing in a high-temperature environment of 35℃.The results indicated that,comparing with only wearing chemical pratective clathing,both LCG and PCM are effective in reducing skin temperature,core temperature,heart rate,etc.,thereby improving human thermal comfort.However,LCG of-fers better improvement in thermal comfort.
