基于极值判优的热环境综合评价方法探讨

设定服装热阻和人体能量代谢率为定值，以PMV=0为依据，建立室内热环境单指标空气温度、相对湿度和风速标准参数库，以此获得基于标准参数的单指标无量纲值，采用极值判优概念构建了综合评价矩阵，进而建立表征各单指标权重的判断矩阵，以获得黑球温度与空气温度差为定值时影响室内热环境的空气温度、湿度、风速三个参数的权重，加权各指标无量纲值，得出综合评价值。据此对一组实测结果采用综合评价方法进行热环境评价，获得空气温度权重为0．815，风速为0．1，湿度为0．085。综合评价结果与删y评价结果具有良好的线性关系，其相关系数接近0．9。通过对比分析可知，论文所提出的热环境综合评价方法可以反映实际室内热环境舒适性。

Discussion on Comprehensive Evaluation Method Based on Extremal Judgement

Data bank of standard parameters of the air temperature,relative humidity and air velocity for thermal comfort were established,based on PMV=0 when clothing thermal resistance and energy metabolism in the human body were set to be constant. The dimensionless quantities for single target was obtained based on the data bank and comprehensive evaluation matrix was constructed,and then the judgment matrix to signify single target was established,so that the weight of the three parameters of air temperature,rela...
