针对我国目前智能建筑中冷源系统运行效率偏低、控制实际应用水平与理论研究水平有相当大差距的现状,本文指出了冷源系统控制对智能建筑节能的重要性,分析了楼宇自控在冷源节能群控中的基本监测与控制、能量调节及水系统控制。包括:多台冷水机组并联运行时的控制策略、机组的阶梯递进、机组轮换、冷冻水温的再设控制等部分。 In view of the current low efficiency of cold source system in intelligent buildings in our country and the gap between actual application level and theoretical research level, the importance of cold source system control in smart building energy saving is pointed out. Energy-saving group control in the basic monitoring and control, energy regulation and water system control. Including: multiple chillers parallel operation of the control strategy, the unit progressive ladder, unit rotation, re-set the frozen water temperature control and other parts.
