大多数冷冻水系统的设计和运行均采用恒定的冷凝器水流量。最近，有一种趋势是将VSD应用于所有组件，以便在采用专门定制的操作策略时实现更高的操作性能。本文通过模拟一个冷凝器水回路实例，研究了不同冷凝器水流量下的节能潜力。仿真结果表明，如果通过阀门或阻尼器对泵水流量和风机流量进行节流，系统在降低冷凝器水流量时会消耗更多的能量。如果泵和冷却塔配备VSD，最佳冷凝器水流量在很大程度上取决于设计条件和冷却器性能对冷凝器水流量的敏感性。当地气候对最佳冷凝器水流量的影响较小。在最佳CW流量附近，系统年总能量消耗对CW流量不敏感。 与恒定最佳CW流量运行相比，采用可变最佳CW流量的节省可以忽略不计。该方法可应用于实际系统，以寻找最优的凝汽器水运行策略。引用:ASHRAE Trans。，第118卷第。德克萨斯州圣安东尼奥2号

Most chilled water systems are designed and operated with constant condenser water flow rates. Recently, there is a trend to apply VSDs to all the components to achieve higher operation performance when specially tailored operating strategies are incorporated. This paper studied the energy savings potential of varying condenser water flow rates by simulating an example condenser water loop. The simulation results show that, if the pump water flow and fan airflow are throttled by valves or dampers, the system could consume more energy when reducing the condenser water flow. If the pump and cooling tower are equipped with VSDs, the optimal condenser water flow is highly dependent on the design conditions and the sensitivity of chiller performance to the condenser water flow. The local climate has a minor effect on the optimal condenser water flow rate. At around the optimal CW flow rate, the system annual total energy usage is not sensitive to the CW flow rate. Compared to operation with a constant optimal CW flow, the savings of applying variable optimal CW flows are negligible. This method can be applied to actual systems to find the optimal condenser water operating strategies.
