【摘要】：为了探讨气冷服的近体调温性能,构建了体表-服装几何模型,采用数值模拟的方法研究了平均皮肤温度、内外温差关于进气速度、进气温度及人体散热率的变化关系。结果表明:体表上半部分温度高于下半部分温度;平均皮肤温度与进气速度成幂函数关系,温差与进气速度成对数函数关系;平均皮肤温度及温差关于进气温度成线性关系,进气温度每降低1℃,则平均皮肤温度降低0.39℃,而温差上升0.41℃;平均皮肤温度关于人体散热率成线性变化,散热率每增大5W/m~2,平均皮肤温度升高0.6℃。
[Abstract]:In order to study the near-body temperature regulation performance of air-cooled clothing, a body surface-garment geometric model was constructed. The relationship between average skin temperature, internal and external temperature difference and inlet air velocity, intake temperature and body heat dissipation rate was studied by numerical simulation. The results show that the temperature of the upper part of the body surface is higher than the temperature of the lower part, the average skin temperature has a power function relationship with the inlet air velocity, the temperature difference has a logarithmic relationship with the inlet air velocity, and the average skin temperature and the temperature difference have a linear relationship with the inlet air temperature. The average skin temperature decreased by 0.39 鈩，
