摘　　要：通过正交数值实验分析了热湿环境参数对PMV影响的显著性,在通常的环境参数变化范围内,影响程度从大到小依次是:空气温度、风速、平均辐射温度及相对湿度.分析了4大环境参数在定PMV控制时对能耗的影响规律及影响显著程度.保持PMV不变的前提下,分别比较了不同热湿环境参数组合下的能耗,发现不同组合之间能耗差异较大,说明其中存在最优参数组合,使得满足人体热舒适的前提下能耗最小.研究结果为今后实现空调系统的PMV优化控制提供了方向和依据.Through orthogonal numerical experiments,the significance of the effect of four thermal en-vironmental parameters on PMV was compared,which indicates that the degree of the influence of four thermal environmental parameters on PMV in descending order is air temperature,indoor wind velocity, mean radiant temperature and relative humidity within the usual range.Furthermore,the influencing laws and the significance of the effect of the four environmental parameters on energy consumption under PMV control were analysed.Under the premise that PMV remains unchanged,the energy consumption of differ-ent combinations of thermal environment parameters were compared.It is found that there is a huge differ-ence between different combinations on energy consumption,which indicates the presence of an optimal combination consumes the minimum energy while satisfying human thermal comfort.The above analysis provides directions and basis for the further study of PMV optimal control of air-conditioning systems.
