商业建筑电气负荷密度调查与分析

Investigation and analysis on electrical load density of commercial buildings

针对目前商业建筑各类负荷的功率密度资料欠缺,通过调研国内大型商业建筑各类负荷的数据,并利用统计学分析得到了动力系统、空调系统以及照明系统负荷的功率密度的选取范围建议值和各类负荷所占比例的推荐值,并且将总建筑面积与各类负荷进行了相关性分析。结果表明总安装容量和总计算有功功率与建筑面积的相关性较强,且呈现显著的线性相关关系,这将为商业建筑电气方案设计提供参考。

In view of the lack of power density data of all kinds of loads in commercial buildings,the data of all kinds of loads in large-scale commercial buildings in China is investigated,and statistical analysis are used to obtain the recommended value of the selection range of power density of power,air conditioning and lighting loads and the recommended value of the proportion of all kinds of loads,and a correlation analysis between the total building area and all kinds of loads is made.The results show that the total installed capacity and the total calculated active power have a strong correlation with the building area and show a significant linear correlation,which will provide a reference for the electrical design of commercial buildings.
