Effects of temperature differences between air and radiation on human thermal loss
摘要：
研究了稳态非均匀温度对人体散热特性的影响。与以往非均匀温度控制方法不同，通过控制辐射温度与空气温度的差值来实现稳态非均匀温度。对于每种温差，又进行了2种操作温度（29，33 ℃）实验。实验结果表明：人体散热量和散热比例与温差呈线性变化，但增减趋势不完全相同；当操作温度升高时，散热量及散热比例的差异增大。
Abstract：
Studies the effect of steady non-uniform temperature on human thermal loss. Unlike previous non-uniform temperature control methods, achieves the steady non-uniform temperature by controlling the difference between the radiant temperature and the air temperature. For each temperature difference, performs the tests at two operative temperatures (29, 33 ℃). The experimental results show that human thermal loss and ratio are linear with the temperature difference, but the characters of increase and decrease are different; when the operative temperature increases, the differences of the capacity and ratio are great. The calculated value can provide references for human thermal load and thermal reaction research.
