中央空调冷水机组群控优化方法研究

摘要

For the central air conditioner equipped with multi⁃ple chillers, the group control strategy is very important to enhance the overall efficiency of the system. In this paper, firstly, the load ef⁃ficiency of each chiller is modeled. Secondly, the air conditioning load is calculated, in the premise of ensuring the function effect, the optimal matching model for air conditioning load and the chillers’ load is established,so as to realize the group control of the chillers. The models and algorithms are not only for saving energy of the air conditioning, but also can be used for air conditioning load regulation. Flexible control of the air conditioning load is achieved.%对于配备多台冷水机组的中央空调来说，中央空调冷水机组的群控方式对于提高中央空调系统的整体效率具有重要意义。首先根据各台冷水机组负荷效率特性建立模型，其次对空调负荷进行计算，在保证空调效果的前提下建立空调负荷和冷水机组负荷的最优匹配模型，实现冷水机组的群控。相关模型和方法不仅可应用于空调节能，而且可以应用于空调负荷调控，实现空调负荷的柔性控制。
