摘要
为了科学有效地评价不同降温背心的降温性能,通过模拟高温中湿环境(温度34℃,相对湿度50%),利用恒功率控制干态暖体假人,获得假人着装时胸部、肩部、腹部、背部和躯干的皮肤温度,对3种降温背心(即蒸发型、相变型和凝胶型)的降温性能进行综合评价。结果表明:3种降温背心均有不同程度的降温效果。蒸发型降温背心质量轻,降温速率缓和,对躯干的有效降温时长为102 min;相变型降温背心质量大,服装动态舒适性差,对躯干的有效降温时长最大为134 min;凝胶型降温背心质量最大,背部降温速率过大,最低温度达29.4℃,存在骤冷、过冷情况,对躯干的有效降温时长最小为96 min;3种降温背心适合在较低劳动强度下穿着。
To evaluate the cooling performance of different cooling vests scientifically and effectively,a dry thermal manikin with constant power in a simulated hot environment(temperature 34℃,relative humidity 50%)was utilized to evaluate cooling performance of three cooling vests(evaporation,phase-change and gel)by measuring chest,shoulder,abdomen,back,and torso skin temperatures.Results show that the three cooling vests have different cooling performance,evaporative cooling vest has lightest weight,moderate cooling rate,optimum comfort performance,and the effective cooling time is 102 min;phase change cooling vest is hard and heavy,has poor clothing fit and dynamic comfort,but has the longest cooling time of 134 min;gel cooling vest is heaviest,the cooling rate of back is high,and the lowest temperature can reach 29.4℃,there exists sudden cooling and supercooling,but has the longest cooling time of 96 min.
