摘　　要：当前制冷空调行业最为关注的要点是节能和可靠性。在所有的系统设计当中,节流装置的控制是满足节能和可靠性的最为关键的因素。本文对当前制冷空调系统中各参数如何影响电子膨胀阀的开度控制进行了梳理,并总结了通过过热度控制电子膨胀阀的控制逻辑,最后通过引入丹佛斯的电子膨胀阀整合控制方案介绍了如何通过过热度实现系统的精确控制。The control method for throttling devices is one of the most effective factors to energy saving and reliability in refrigeration and air conditioning system design. This article describes how the system parameters work upon electron ic expansion valve, as well as the control logic that can be used when using suction superheat to control electronic ex pansion valve. Some conclusion about how to make the system work precisely through superheat can be drawn from the example of Danfoss integrated optimized electronic expansion valve.
