摘要
采用阻容网络法建立了内融冰式蓄冰槽模型,搭建了冰蓄冷空调系统仿真器.利用仿真器模拟和分析了冰蓄冷系统的5种运行模式.提出了用户侧供水温度优化和冷机出水温度优化两种控制策略,使系统能够调整优化、适应负荷和室外气象条件的变化.仿真实验表明,所建模型适合冰蓄冷系统动态仿真的需要,两种优化策略有较好的节能效果.
A quasi-dynamic simulation model was set up based on R-C network method and the simulator of air conditioning systems with ice storage tank was completed. Five operation modes of the system were demonstrated to analyze and correct the ice storage tank model and the system simulator. Two optimal control strategies, supply water temperature optimal control and chiller outlet water temperature optimal control, were presented. The optimal strategies were tested and validated based on the simulation plat- form. The results show that, compared with the conventional strategy of fixed set-point, the two optimal control strategies presented can both save energy.
