通过水泵变频对空调水系统进行变流量控制是目前空调系统的主要节能手段.针对负荷变化趋势大致相同的商业建筑,基于局部控制和全局协调优化控制两种模式,进行了水泵的能耗分析;提出了一种根据水力失调度来确定最不利支路位置的新方法.并建立了变流量水系统动态优化函数,实现了水系统的全局协调优化控制.分析结果表明该协调优化控制方法,不仅可以减少因管网耦合而带来的水力畸变,而且可以取得更佳的节能效果.

At present,to regulate the water flowrate by adjusting the pump frequency is one of the major methods for energy saving for central air-conditioning system.For the commercial buildings which load change is in the same trend roughly,energy consumption of the pump is analyzed based on two modes of local and overall coordinated control;According to the size of the water maladjustment degree,a new approach is used to obtain the most disadvantaged position of hydraulic network.Dynamic optimization function is provided for variable volume water system.The overall coordination control is achieved for the water system. The results show that the coordinated control method can not only reduce hydraulic aberration of the coupling pipe network,but also achieve better energy-saving effect.
