介绍了某宾馆传统中央空调装置的运行方式,指出其存在的局限性,采用变频调速、集散控制、模糊PID等技术实现了压缩机、水泵转速的控制以及它们的平稳启动和停止,克服了电机直接启动或停止所带来的电流和机械冲击,更重要的是避免了电机长期在满负荷状态下运行,有效地节约了能源,提高了经济效益,具有很大的应用价值。 The running mode of a traditional central air conditioning unit in a hotel is introduced. The limitation of the operation is pointed out. The control of the speed of compressor and pump as well as the steady start and stop of the compressor are realized by the technologies of frequency conversion speed regulation, distributed control and fuzzy PID. More importantly, it avoids the long-term operation of the motor under full load condition, effectively saving energy and improving economic efficiency, and has great application value because of the current and mechanical impact caused by the motor being directly started or stopped.
