温度突变下人体热响应随时间的变化特性及评价
Characteristics and evaluation of human thermal responses with time under temperature step change condition
摘要：
通过人工气候室模拟偏热环境下中性-热-中性温度突变，对20名受试者开展了不同突变温差和突变方向下的人体热响应实验。结果显示：突变温差越大，人体的平均皮肤温度增量越大，达到稳定所需时间越长；引入修正的Knothe时间函数，量化了突变环境下平均皮肤温度随突变温差、方向及暴露时间的调节特点；结合皮肤温度预测模型，建立了包含平均皮肤温度及其变化率的人体热感觉预测模型，简化了动态环境下人体热感觉预测模型应用。
Abstract：
To explore the effect of temperature changes on human thermal response, conducts a neutral-warm/hot-neutral temperature change experiment with 20 volunteers in a well-controlled climate room. The results show that the mean skin temperatures of volunteers and the stable time increase with increasing temperature differences. Presents a time-based function to quantify the relationship between mean skin temperature and temperature differences, directions and time. Combined with mean skin temperature prediction model, obtains a thermal sensation prediction model with stable and dynamic items and simplifies the application of human thermal sensation prediction in dynamic environment.
