摘　　要：动力分散式空调水系统采用分布式水泵取代平衡阀的方式,为空调系统在建筑中的应用带来了一定的节能空间。本文采用Pipe Flow Expert模拟软件,建立某商场的动力分散式空调水系统仿真模型,并设定相应的评价指标将其与传统的动力集中式空调水系统进行对比,分析两者在节能性与稳定性方面的差异。结果表明,动力分散式空调水系统的节能优势明显,但稳定性不如动力集中式空调水系统。该研究为动力分散式空调水系统在实际工程中的推广及应用提供参考。The distributed power air-conditioning water system uses distributed pumps to replace balance valves,which helps to the energy-saving for the air-conditioning system applied to the building.The simulation model of distributed power air-conditioning water system in a market is established using Pipe Flow Expert software.Comparing it with the traditional concentrated power air-conditioning water system by related evaluation index,the differences about energy-saving and stability between them are analyzed.The result shows that the distributed power air-conditioning water system has various advantage of energy-saving,but it's weaker than concentrated power air-conditioning water system on stability.The research provides reference for the popularization and application of distributed power air-conditioning water system in the actual engineering.
