摘　　要：探讨冬季采暖时的PMV-PPD新的综合求解法。在静坐、站立、轻作业的状态下,对室内空气温度与平均辐射温度相等,相对湿度20%、气流速度0.1～0.5m/s的室内空气温度16～24℃与PMV关系进行图解化的同时,探索居室者在冬季不同活动量的情况下求解PMV的计算公式。为追求舒适采暖设计技术提供简便计算PMV的方法。The new calculate method of Predicted Mean Vote （PMV） and Predicted Percentage of Dissatisfied （PPD） have been discussed under heating in winter season. The relationship between the ambient air temperature at the range of 16～24℃ and PMV is turned into nomograph for seated, quiet, standing and sedentary activity under the condition of relative humidity 20%, air velocity 0.1-0.5 m/s, and the equal mean radiant temperature against to the ambient air temperature. At the same time, the equation has been obtained for PMV calculation under different metabolic rate in winter season. The new calculate method of PMV is provided through nomograph together with equation for the comfortable design condition with heating technology.
