摘　　要：为解决中央空调运行中水力系统水力失衡的问题,确保空调节能运行.本文运用经典流体网络理论,将空调管网系统建立节点网路矩阵方程,充分考虑管网水力特性及各参数影响,编译参数逻辑语言,将求解可视化.基于方程求解,得到静态平衡的初始网络系统.系统运行时末端负荷量不断改变,通过各阀门的协作,在短时间达到目标流量并维持新的平衡,同时对该过程的稳定性进行分析.研究结果表明:静态平衡为出发点,系统末端展现出良好的可调性;可控性较好的动态网络,仍然存在失衡的风险性.In order to solve the problem of central air-conditioning hydraulic unbalance and ensure energy-saving operation, this paper used fluid network theory, and established network node matrix of existing system. The hydraulic characteristics and influence of hydraulic parameters were fully considered, the various parameters＇ logical relationship was compiled and visualization of the solution was realized. This paper obtained the static equilibrium starter system based on the solution of equation. The terminal of air conditioning loads keep changing when system is running, and it reaches target in short time and maintain new hydraulic equilibrium rely on the valve gate＇s cooperation. The progress stability is analyzed at same time. The results show that using static equilibrium as a starting point, the system terminal exhibits favorable tunability; Although dynamic networks has better controlling nature, it still exists unbalanced stability
