摘　　要：本论文应用预计冷热感指标（PMV）的热舒适方程式计算方法,在热舒适指标1≥PMV≥-1范围内,计算室内取暖环境的热舒适参数的阈值,探索其至适值。在冬季取暖环境相对湿度30%～60%,气流速度0.1～0.2m/s,静坐、坐姿轻作业的代谢量分别为58.15、69.78 W/m2的计算条件下,标准着衣量为0.155 m2.K/W满足PMV≥-1的空气取暖,静坐、坐姿轻作业的至适温度分别不小于21.0、18.4℃;在空气温度18℃的条件下,满足PMV≥-1的静坐、坐姿轻作业的,标准着衣量热辐射取暖的至适平均辐射温度分别不低于25.3、19.0℃,或空气取暖的至适着衣量各不少于0.217、0.163 m2.K/W。According to the thermal comfort index of 1≥PMV≥-1,the threshold of parameters are computed for thermal comfort based on the PMV＇s thermal comfort equations,and inquiring out their comfort threshold under indoor heating environment.The computed conditions are relative humidity 30%~60%,relative air velocity 0.1~0.2m/s,the metabolic rate of 58.15 W/m2 for seated,of 69.78 W/m2 for light sedentary activity in winter.In order to achieve range of PMV≥-1,while the normal clothing insulation is 0.155m2·K/W,the comfort threshold of temperature is never lower than 21.0℃ for seated,18.4℃ for light sedentary activity under the heating air-conditioning.When the air temperature is 18℃ for achieving PMV≥-1,the comfort threshold of mean radiant temperature is never lower than 25.3℃ for seated,19.0℃ for light sedentary activity under the normal clothing insulation and heating includes thermal radiant,or,the comfort threshold of clothing insulation is never less than 0.217 m2·K/W for seated,0.163m2·K/W for light sedentary activity under the heating air-conditioning.
