The invention particularly relates to an energy-saving group control method for a central air-conditioning system based on fuzzy self-adaptation. The method comprises chilled water system control, cooling water system control and air treatment system control. The chilled water system control comprises water chilling unit addition and reduction control and chilled water pump frequency conversion control; the cooling water system control comprises cooling water pump frequency conversion control and cooling tower fan frequency conversion control; and the air treatment system control comprises airsupply volume control and fresh air ratio control. A self-adaptive fuzzy-PID controller is adopted for room temperature control of the central air-conditioning system, a control steady-state error issmall, and the robustness is high. 本发明具体涉及一种基于模糊自适应的中央空调系统节能群控方法，中央空调系统节能群控方法包括冷冻水系统控制、冷却水系统控制以及空气处理系统控制；所述冷冻水系统控制包括冷水机组加减机控制与冷冻水泵变频控制；所述冷却水系统控制包括冷却水泵变频控制与冷却塔风机变频控制；所述空气处理系统控制包括控制送风量控制与控制新风比控制；本发明中中央空调系统房间温度控制采用的是自适应模糊-PID控制器
