本文针对公共建筑中的空调能耗,尤其是冷水机组能耗过大的问题,建立了多台冷水机组配置模型及优化目标。以某办公建筑为例,分析了不同运行策略下多台冷水机组运行时的能耗,同时对不同策略和配置情况下的运行情况进行了经济性比较。分析可知,当选用多台机组时,平均分配负荷的运行策略比较节能,节能效果视组合方式的不同而不同,其中容量相同的组合方式采用该运行策略优势最为明显。
In this paper, the air conditioning energy consumption in public buildings, especially the chiller excessive energy consumption, the establishment of multiple chiller configuration model and optimization goals. Taking an office building as an example, the energy consumption of multiple chillers under different operation strategies is analyzed. At the same time, economic comparison is made between different strategies and configurations. The analysis shows that when multiple units are selected, the operation strategy of average load sharing is more energy-efficient and the energy-saving effect is different depending on the combination mode. The combination strategy with the same capacity and the advantage of the operation strategy is the most obvious.
