【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。更多还原

【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.更多还原
