双联变频空调系统中各蒸发器间相互影响以及各参数的强烈耦合 ,致使该系统的控制特性非常复杂 .为此 ,从双联变频空调系统的运行特性的研究结果出发 ,引进负荷系数并采用模糊推理方法来确定各房间的负荷 ,制定出该系统中双电子膨胀阀及变频压缩机的控制方法 .利用集总参数法 ,建立了包括房间对象和各部件的系统动态热力学模型 ,对系统的控制进行仿真 .仿真结果表明 ,该控制方法具有响应快、超调小、控温精度高的优点
Therefore, the control characteristics of the system are very complicated.Therefore, based on the research results of the operating characteristics of the dual-frequency inverter air-conditioning system, the introduction of the load factor and the use of Fuzzy inference method to determine the load in each room, to develop the system of dual electronic expansion valve and inverter compressor control method.Using the lumped parameter method, the system dynamic thermodynamic model including the room object and each component is established, Control simulation.The simulation results show that the control method has the advantages of fast response, small overshoot and high precision of temperature control
