摘　　要：进行文献调研，统计不同气候区办公建筑空调动态冷负荷的实测及能耗模拟数据，通过对调研数据的处理得出15条空调冷负荷时间分布曲线。利用一种基于EDA技术并结合经典概率统计法的改进的处理方法——箱图剔除法，对时间分布曲线进行处理分析，剔除数据样本中的离群样本；利用SPSS统计软件对剩余的数据样本的分布形态进行分析，求出各段负荷率区间上的时间频数平均值的95％置信区间，定义为时间频数基准带，进而对办公建筑的空调冷负荷特性进行分析。最后，得出空调系统为风机盘管加独立新风的办公建筑空调冷负荷的时间分布主要集中在30％～70％负荷率区间；时间频数基准带的整体分布形态近似呈扁平状的正态分布等结论。The paper conducts statistical analysis of office building＇s dynamic cooling load from actual measurement and simulation result in different climate zones 15 cooling load time profile are obtained by further processing of the survey data. And the time distribution profile is processed and analyzed by using box figure out method which bases on EDA technology and combine classics statistics probability method through getting rid of the data set＇s stray sample. Also, this paper use SPSS statistical software to analyze the rest of the new data distribution patterns of the samples and get 95% confidence interval of each segment on the frequency range of the load factor for the mean number, which is defined as the time reference frequency band, and then the office building cooling load characteristics were analyzed, finally, we get conclusions that primary air fan-coil system of office building cooling load time is mainly concentrated in the 30 to 70 percent load factor interval and overall time-frequency distributions of the benchmark was flat with the approximate conclusion of the normal distribution.
