        摘要:

        利用PMV理论和谐波反应法分析了环境参数对空调能耗的影响,得知各参数对空调能耗的影响由大到小排序为:温度、相对湿度、风速。分别对PMV=0和PMV=0.75时不同参数组合的空调能耗进行了计算,发现最优的参数组合可使空调能耗最小。简要介绍了变PMV控制的思想,并通过计算得知变PMV控制的空调能耗介于PMV=0和PMV=0.75控制之间,但出于人员健康的考虑,认为变PMV控制优于定PMV控制。

        Abstract:

        Analyses the influence of environmental parameters on the air conditioning energy consumption using the PMV theory and the harmonic response method. The results show that the influence of each parameter on the energy consumption sorted from high to low is temperature, relative humidity and wind speed. Calculates the air conditioning energy consumption of different parameter combinations when PMV=0 and PMV=0.75, and turns out that the optimal parameter combination can minimize air conditioning energy consumption. Presents the idea of variable PMV control, and obtains that the air conditioning energy consumption with variable PMV control is between the two results calculated from PMV=0 and PMV=0.75. However, considering the health, the variable PMV control is better than constant PMV control.
