基于负荷预测的机场航站楼冷源系统运行调控策略研究与应用

Control Strategy of Chiller Plant for Airport Based on Load Forecasting Method

机场航站楼作为重要的交通枢纽,其室内环境营造与节能减排工作逐渐成为航站楼空调系统高效运行的重要任务和挑战。以我国北方寒冷地区某枢纽机场航站楼为例,利用其历史运行数据,建立了供冷负荷预测模型,定量刻画了供冷负荷影响因素,从而为合理供冷、营造舒适室内环境提供了关键方法。随后基于负荷预测模型,开展了冷源系统中冷水机组及冷水输送系统运行调控策略的优化研究,并根据实时运行数据持续优化运行策略,以提升冷源系统供冷季运行性能,从而实现提高效率、节能减排的目标。

As an important transportation hub,the indoor environment construction and energy conservation and emission reduction have gradually become the crucial tasks and challenges for the efficient operation of air conditioning system in airport terminal.The terminal building of a hub in the cold area of northern China is analyzed,using its historical operation data,a cooling load forecasting model is established,quantitatively describing the influencing factors of cooling load,thus providing a key method for reasonable cooling condition and creating a comfortable indoor environment.The operation control strategy of water chiller and the cold water transmission system are optimized based on the load forecasting model.The operation strategy is continuously optimized according to the real-time operation data,so as to improve the operation of the cold source system in the cooling season,and efficiency,energy saving and emission reduction.
