【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.
[Abstract]:Through orthogonal numerical experiments, the significance of the influence of thermal and wet environmental parameters on PMV is analyzed. In the usual range of environmental parameters, the degree of influence from large to small is: air temperature, wind speed. Mean radiation temperature and relative humidity. The influence of the four environmental parameters on energy consumption and the degree of influence on the energy consumption were analyzed under the condition of constant PMV control, while keeping the PMV unchanged. The energy consumption under different combination of heat and wet environment parameters is compared, and it is found that there are great differences in energy consumption among different combinations, which indicates that there is an optimal combination of parameters. The energy consumption is minimized under the premise of satisfying the thermal comfort of human body. The research results provide the direction and basis for the realization of PMV optimal control of air conditioning system in the future.

【正文快照】： 目前,大多数舒适性空调均采用定温控制,然而,影响人体热舒适性的环境因素除了温度还有相对湿度、风速和平均辐射温度,人体的热舒适感是这些因素共同作用的结果.在两个围护结构等条件完全相同的房间,即使温度相同,而其他热湿参数不同的情况下,人体的热舒适度是不同的[1],同时,
