| 摘 要： | 为了解决冰蓄冷中央空调存在的板换堵塞问题,提出了以制冰板换回水温度为控制变量,采用模糊控制预热变频泵流量的方法,以实现制冰快速性和可靠性的解决方案.设计了预热泵流量模糊控制器,研制了制冰板换防堵塞的预热回路;采用离线计算与在线查询相结合的方法,对基于西门子可编程逻辑控制器（PLC）的冰蓄冷中央空调系统进行了试验研究,给出了制冰板换回水温度控制结果,并对该模糊控制结果与传统的PID控制结果进行了比较.试验结果表明：在环境温度为28℃时,采用模糊控制调节制冰板换回水温度,其下降时间为90 m in,调节时间为158 min,稳态误差为0.26℃.该方案为智能化冰蓄冷中央空调稳定运行提供了依据.

| Abstract: | The plate heat exchanger of ice-storage centralized air-conditioning system is always jammed.With the objective of making ice quickly and reliably,a solve scheme was proposed.With consideration of the return water temperature of ice-making plate heat exchanger as controlled variable,the scheme regulated the flow rate of pre-heat pump by means of fuzzy control.A fuzzy controller was designed to dominate the flow rate of the pump,and a pre-heat loop was developed to prevent the ice-making plate heat exchanger from jamming.The experimental investigation of Siemens PLC based ice-storage centralized air-conditioning was performed by combining offline calculation with online inquiry,and the control effect of return water temperature of ice-making plate heat exchanger was compared with the traditional PID control.The results show that when the environmental temperature is 28 ℃,the fall time,the settling time and the steady state error of return water temperature are 90 min,158 min and 0.26 ℃,respectively.The scheme provides the basis for stable operation of the intelligent ice-storage centralized air conditioning system. |
