变频器技术在大区域中央空调系统中的应用

The Application of Inverter Technology in the Large-Scale Area for Control System of Central Air Conditioning

中央空调系统是工业中耗能的重要部分。针对大区域分区独立式中央空调系统存在的工况及环境变化适应性差,控制惯性较大,容易产生超调,能源浪费等问题,文章提出将变频调速技术与神经网络控制相结合,以克服采用常规PID控制方式在相邻的分区中有时会出击一个区域制冷,另一个区域加热的现象,融合技术的应用有效地避免了系统振荡造成的能源巨大浪费。

The system of central air conditioner is most important part in the industrial energy consuming of power, aimed at the problem of being bad in work situation and environment adaptability, and big in control inertia, and easy in producing oscillation, and waste in energy, and so on, the paper proposed combining frequency varying technology with artificial neural network technology to overcome the phenomena that will be produced by traditional PID control mode, for example, sometime this subarea is cooling, and the next to subarea Is heating, the system oscillation must be produced. The application of amalgam ation technology can effectively avoid oscillation phenomena and make a great energy saving.
