摘　　要：为了满足制冷系统节能要求,设计出一种采用ARM LM3S8970芯片的制冷系统智能控制器。该控制器硬件构成为数据采集模块,通信模块,输出控制模块和显示模块;软件功能包括现场监控,远程控制,和多控制器级联群控等。该控制器采用变最小过热度控制方法,以保证制冷系统运行在最小稳定过热度附近,并通过实验验证了该控制器的节能优势。To satisfy energy efficiency requirements of the refrigeration system, a kind of intelligent controller based on embed- ded ARM LM3S8970 chip was designed. The controller hardware structure includes data acquisition modules, communication mod- ules, output control module and display module. Its software capabilities included local monitor, remote control, and multi-controller cascade group control. The controller used a variable minimum superheat control method, to ensure that the refrigeration system to run as far as possible in the vicinity of the minimum stable superheat. And through the experiments, the data of the experiments ver- ifies outstanding energy-saving effect of the controller.
