摘要
本文以空调系统各部分的总能耗最小为目标函数,选取冷却水流量率和冷水出口温度为优化参数,建立了某宾馆空调系统的优化模型,并利用MATLAB计算出空调系统不同负荷率时,冷却水流量率和冷水出口温度的最优运行值。优化结果表明:当这两个参数控制在最佳值运行时,空调系统的总功率比额定功率明显下降25.5%到38.3%不等,节能效果明显。
The lowest energy consumption was chose as the objective function in this paper, and the flow rate of cooling water and the outlet temperature of chilled water were chose as optimization parameters. With the help of MATLAB the optimal value of the flow rate of cooling water and the outlet temperature of chilled water were obtained for different load ratio. The optimization result shows that control the operation parameters rationally can make the air-conditioning system＇s total power drops from 25.5% to 38.3% compared with rated power obviously.
