基于模糊理论的中央空调水自动控制系统设计

由于中央空调水系统非线性、大滞后的特点,目前楼宇自控和通用变频器控制方法的节能效果不显著,提出了模糊控制方法,通过负荷预测模糊控制的冷冻水控制和自适应模糊算法的冷却水控制,实现了冷水机组制冷量的供给与末端负荷需求大小相匹配、冷却水系统处于最大效率运行,取得了最大的节能效益。最后完成了冷冻站中央空调水系统的控制设计,并以实际工程测试结果分析了中央空调模糊控制取得节能效果。

Design of air conditioning automatic control system based on mould and theory

In view of the non-linear and large time-delay characteristics of the air conditioning water system,the energy saving effect of the current building automatic control and the universal frequency converter control methods is not significant,and a mold and control method is proposed.Through load forecasting mode and self-adaptive mode and cooling water control algorithm,the supply of cooling capacity of chillers is matched with the demand of terminal load,and the cooling water system operates at maximum efficiency The maximum energy-saving benefit has been obtained.Finally,the control design of the air conditioning water system in the freezing station is completed,and the energy saving effect of the air conditioning is analyzed based on the actual engineering test results.
