摘　　要：冷却水系统的优化由于受到冷水机组能耗和冷冻水系统运行状态的影响,导致节能优化困难。本文采用大系统优化方式实现对变风量空调系统的分解协调优化,建立冷却水系统、冷水机组和冷冻水系统的大系统模型,充分考虑冷水机组能耗的影响因素,实现冷却水系统的节能优化。建立冷却水系统和冷水机组的能耗模型,通过能耗仿真表明采用大系统优化方式可以在全局优化的基础上实现冷却水系统的节能运行。为提高变风量空调系统的运行效率提供了一种有效方法。The optimization of cooling water system relates to the energy consumption of water chiller and the oper- ating condition of the chilled water system, so the optimization is in difficulty. The paper adopted the large scale sys- tem optimization method to achieve the decomposition and coordination optimization of variable air volume air condi- tioning systems, and provided the large scale system models of cooling water system, water chiller and chilled water system. Fully considering the influencing factors about the chiller energy consumption, we achieved the energy saving optimization of cooling water system. The energy consumption model of cooling water system and water chiller was es- tablished. The results of energy consumption simulation show that the large scale system optimization method can a- chieve the energy saving operation of cooling water system based on the global optimization. It provides an effective method to improve the operating efficiency of variable air volume air conditioning systems.
