摘　　要：作为电子膨胀阀控制的组成部分,过热度控制器对于提高制冷系统的性能非常重要。在实践中发现,现有的过热度控制器仍然存在一些需要改进的地方。本文提出一种新型的过热度控制器,包括启停阶段控制优化、制冷和制热不同模式下控制优化、变频系统控制优化以及紧急情况控制优化。该控制器可以覆盖各个应用场景,提高对系统需求的响应度,更为智能,系统效率更高。通过硬件和软件的优化,最大可以节省20%的成本。As a part of Electronic Expansion Valve (EEV) control, superheat controller is very important to improve the performance of refrigeration system. In practice, there are still some areas to improve in existing controllers. In this paper, a new superheat controller is introduced, including on-off control optimization, cooling and heating control optimization, inverter system control optimization and emergency mode control. The controller can cover different applications, increase response speed to system demand, be smarter and have higher system efficiency. With the optimization of hardware and software, cost saving is up to 20%.
