摘　　要：商业综合体由于在内部空间结构、功能及人员行为方面的复杂性,其负荷特征、空调运行及室内环境等状况复杂,冷站设计及节能优化需要结合自身特点。首先,针对商业综合体分析其空调使用需求特征,通过室内热湿环境实测分析,发现室内环境较传统商业建筑波动较大,不同业态室内环境有显著差异。其次,通过冷站实际运行工况分析其能耗特征、供冷系统运行模式及问题,发现商业综合体冷负荷稳定、冷站运行时间长、冷机设计容量普遍存在过大的问题。最后,利用DeST软件对两类典型空间分布(环绕型、中庭型)的商业综合体建立模型,分析不同区域、不同时间段的负荷特征,并根据业态负荷或时间负荷特征对冷源设计方案进行优化设计和对比,发现按照业态负荷特征对体量大、业态布局分散且各业态负荷差异大的商业综合体进行冷源设计对冷站节能有利。Because of the complexity of the internal space structure and function diversity,personnel behavior in commercial complex,the load characteristics,plants operation and indoor environment are complex.Therefore,the chiller plants design and energy optimization need to combine their own characteristics.Firstly,through indoor thermal environment test to analyze the air conditioning demand of commercial complex,it is found that the indoor environment fluctuates more greatly compared with traditional commercial buildings,and there are significant differences among different commercial types.Secondly,the refrigeration system operation is analyzed through chiller plants operation records.It is indicated that the cooling load of commercial complex is relatively stable with the refrigeration system running for a long time,and the design capacity of the plants is generally too large.Finally,the load characteristics is analyzed through DeST modelling,and different chiller plants design optimization is compared.The result shows that the refrigeration system design method according to the commercial type load distribution is beneficial for energy efficiency,especially in the commercial complex with scattered commercial type layout and large difference in cooling load of different commercial type.
