摘　　要：为提升精密空调压缩机节能性,提出基于PID技术的精密空调压缩机柔性控制节能系统设计。硬件方面针对温度采集器和驱动控制器进行设计;软件方面根据精密空调压缩机柔性控制特点,构建节能工作方案。利用PID技术设计柔性迭代控制模型,实现空调温湿度输出的精确控制。针对PID控制器参数进行自适应整定,再结合蚁群算法实现压缩机柔性控制节能。系统测试结果表明,应用所设计的节能系统进行为期半个月的测试,与往年同一时期精密空调压缩机柔性控制用电量相比,节电量达到了3 103 kW·h。In order to improve the energy-saving performance of precision air-conditioning compressors, a flexible control energy-saving system design for precision air-conditioning compressors based on PID technology is proposed.The hardware is designed for the temperature collector and drive controller.In terms of software, an energy-saving work plan is constructed according to the characteristics of flexible control of precision air-conditioning compressors.PID technology is used to design a flexible iterative control model to achieve precise control of the temperature and humidity output of the air conditioner.Self-adaptive tuning of PID controller parameters is combined with ant colony algorithm to achieve energy-saving compressor flexible control.The system test results show that the energy-saving system designed for a half-month test has saved 3 103 kW·h compared with the flexible control power consumption of precision air-conditioning compressors in the same period in previous years.
