摘　　要：在Matlab/Simulink中搭建集中空调系统控制仿真模型,基于中法能源中心集中空调系统的实例进行计算,在满足房间舒适性的要求下,提出变水温和变风量优化控制策略,可以取得更好的节能效果。仿真研究表明,空调负荷越小,变水温和变风量优化控制策略的节能效果越突出。在空调负荷率为60%时,采用冷水供水温度为12℃,风机频率为35.8 Hz,可比仅采用变水量调节节能13.3%,比仅采用变风量调节节能5%。The control simulation model of the central air.conditioning system is set up in Matlab/Simulink,and calculated on the basis of the example of the central air.conditioning system in China.France Energy Center.The optimal control strategy of variable water temperature and variable air volume is proposed to achieve better energy saving effect while satisfying the room comfort.The simulation results show that the smaller the air.conditioning load is,the more effective the energy saving effect of the variable water temperature and variable air volume control strategy is.When the air-conditioning load rate is 60%,the chilled water supply temperature is 12℃and the fan frequency is 35.8 Hz,which can save 13.3%energy than the strategy of variable water volume,and save 5%energy than the strategy of variable air volume.
