摘要/Abstract

摘要： 为改善消防服的热舒适性,制备一种无机相变材料,基于人工环境舱的高温高湿环境开展模拟试验,得出消防服内空间温度分布特征,计算出高温高湿高强度试验组中人上肢躯干的产热量;并以试验数据为依据,开展无机相变材料的改进试验研究。结果表明:环境温度变化比湿度变化对人体皮肤温度变化的影响更大,消防服内空间各部位温度由高到低的排序为左肩胛骨、左肩部、左腰、右肩胛骨、右肩部、右腰、右腹、左腹、正面中部、后背中部;在温度和湿度最高的环境条件下,人员进行重强度劳动时,上肢躯干部位皮肤蒸发散热量为7.20 kJ;十水硫酸钠与碳酸钾两者配比为3∶1 时材料的降温效果最好。

Abstract: In order to improve thermal comfort of fire-fighting clothing, an inorganic phase change material was prepared, and simulation tests were carried out under high temperature and humidity environment in an artificial cabin. Secondly, spatial temperature distribution characteristics of anti-fire suits were obtained and thermal output of upper torsos from high temperature, humidity and strength group was calculated. Then, improvement experiments were performed based on test data. The results show that change of temperature has more significant influence on variance of skin temperature than that of humidity. Temperature of each part under suit range from high to law as left shoulder blade, left shoulder, left waist, right shoulder blade, right shoulder, right waist, right abdomen, left abdomen, front middle and back middle. Under circumstance of highest temperature and humidity, evaporation and heat dissipation of skin on upper torsos was 7.20 kJ with intense labor. The material shows optimal cooling effect when ratio of sodium sulfate decahydrate and potassium carbonate is 3∶1.
