Abstract：A double closed‑loop control model is used to control the chilled water flow of a central air‑conditioning system and work out a chilling unit control strategy. On this basis,intelligent methods such as fuzzy control,neural network and genetic algorithm are used to solve uncertain factors such as manpower use and climate changes. The model is combined with a conventional linear controller to guarantee control accuracy and following performance for the system,improve the system self‑learning,self‑adjustment and decision‑making capabilities and seek for the best solution for energy saving.

Key words：variable‑water‑volume air‑conditioning system;double closed‑loop control;intelligent control;constant temperature difference control;AI algorithm;big data;control strategy;following performance

摘　要：利用双闭环控制模型，对中央空调系统中的冷冻水流量进行控制，制定冷冻机组控制策略；在此基础上应用模糊控制、神经网络、遗传算法等智能方法，来解决人的使用、天气变化等不确定因素，与传统线性控制器相结合，取长补短，既保证系统的控制精度和跟随性，又增加系统的自学习、自调整及决策能力，寻找节能控制的最优解。
