摘　　要：分析了同型号变频冷冻水泵并联运行时的特性模型,定义了同型号变频冷冻水泵并联运行时的高效流量区间。在干管定压差控制下,以冷冻水泵高效运行为约束条件,给出了寻找并联变频水泵最优转速比和最优台数的优化控制策略。最后,结合实例分析了该冷冻水系统优化控制策略的节能效果。The article analyzes characteristics model of same type variable frequency chilled water pumps in parallel and defines high efficiency flow interval of same type variable frequency chilled water pumps in parallel during operation. Under the constant pressure difference control of main pipe with high efficiency operating chilled pumps as constraint condition, it looks for optimal control strategy of variable frequency water pumps optimal speed ratio and optimal operation pumps numbers in parallel. Finally it analyzes energy saving effect of chilled water pumps system after optimal control strategy combined with case study.
