摘　　要：就严寒地区冬季外窗附近较低的平均辐射温度的变化对人体的热舒适影响进行讨论.经计算,室内距外窗0.5 m处的平均辐射温度可比空气温度低3℃;在衣物热阻较小、空气温度较低、相对湿度较低的环境下,平均辐射温度的变化,对人体的热舒适影响会较大;当PMV的绝对值大于1的时候,平均辐射温度的变化对人体热舒适影响会较为明显.The paper discusses the influences of human thermal comfort caused by the change of mean radiation temperature near the window in winter. According to calculations, mean radiation temperature is 3 ℃ lower than air temperature away from window. Human radiation temperature would be affected obviously by mean radiation temperature in the conditions of lower clothing thermal residence, air temperature and relative humility. It would be also affected obviously when absolute value of PMV is greater than 1.
