在人工气候室内研究了不同劳动强度下至适温度标准。结果表明:(1)国家体力劳动强度Ⅰ级,着衣量(Clo)0.8±0.15或体力劳动强度Ⅰ级至Ⅱ级以下,着衣量0.7±0.15时,至适温度为24±2.5℃;如体力劳动强度为Ⅱ级,着衣量(clo)0.7±O.15,至适温度为22±2.5℃。(2)平均皮温对环境热负荷的反应明显,当着衣量(Clo)0.7左右时,至适温度下的平均皮温为32—32.5℃。 In the artificial climate laboratory under different labor intensity to fit the temperature standard. The results showed that: (1) The national physical labor intensity grade Ⅰ, the clothing cloisonné volume (Clo) 0.8 ± 0.15 or physical labor intensity Ⅰ grade to grade Ⅱ or less, the clothing volume 0.7 ± 0.15, the suitable temperature is 24 ± 2.5 ℃; The labor intensity is grade Ⅱ, the amount of clothing (clo) is 0.7 ± O.15, and the suitable temperature is 22 ± 2.5 ℃. (2) The average skin temperature had obvious response to the environmental heat load. When the Clo was about 0.7, the average skin temperature at the proper temperature was 32-32.5 ℃.
