【摘要】：為了探討氣冷服的近體調(diào)溫性能,構(gòu)建了體表-服裝幾何模型,采用數(shù)值模擬的方法研究了平均皮膚溫度、內(nèi)外溫差關(guān)于進(jìn)氣速度、進(jìn)氣溫度及人體散熱率的變化關(guān)系。結(jié)果表明:體表上半部分溫度高于下半部分溫度;平均皮膚溫度與進(jìn)氣速度成冪函數(shù)關(guān)系,溫差與進(jìn)氣速度成對(duì)數(shù)函數(shù)關(guān)系;平均皮膚溫度及溫差關(guān)于進(jìn)氣溫度成線性關(guān)系,進(jìn)氣溫度每降低1℃,則平均皮膚溫度降低0.39℃,而溫差上升0.41℃;平均皮膚溫度關(guān)于人體散熱率成線性變化,散熱率每增大5W/m~2,平均皮膚溫度升高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，
