2004年7月28日 · The electronic expansion valve (EEV) operates with a much more sophisticated design. EEVs control the flow of refrigerant entering a direct expansion evaporator. They do this in response to signals sent to them by an electronic controller.

电子膨胀阀（Electronic Expansion Valve，EEV）是一种在空调系统中使用的电子控制的膨胀阀。 它是一种精确控制制冷剂流量的装置，用于调节制冷剂在蒸发器中的流动量，以实现更精确的温度控制和能效优化。

An Electronic Expansion Valve, or EEV for short, is installed before the evaporator in an air handler/coil and after the condenser in a heat pump. It regulates the refrigerant flow rate to
