摘要
针对VRV-VAV联合空调系统,本文提出了一种优化控制策略,通过改变屋顶机送风温度设定值实现了系统的优化控制。采用状态参数自适应递归和时间序列分析法建立了系统能效比的预测模型,并针对模型的问题对其进行了修正,进而提出一种组合预测模型。修正后的模型平均误差为0.05%,最大误差仅为0.342%,将其应用于系统的优化控制节能率可以达到6.7%。
Optimal control strategy for the VRV-VAV combining air conditioning system was proposed, and the energy saving operation was realized by changing the supply air temperature set point. The adaptive recursive method and time series analysis method were adopted to set up the prediction model, and revisions were made for insufficiency of the model. The mean and max errors of the revised model are 0.05% and 0.342%. The energy consumption can be reduced to6.7% after applying the revised model to the optimal control strategy.
