如您选用其他厂家生产或特制的非Danfoss控制器 来驱动ETS电子膨胀阀，请务必注意一下几点，以 防缺步。 a. 为了保证阀门的完全关闭，控制器应带有使阀门在 关闭方向过盈的功能。建议过盈步数为全步数的 10%。 b. 缺步的数量会随着阀门开启度的变化量而增加。可 以通过控制器，在确定阀门开启度的变化量后，对 缺步进行补偿。 警告: 除非安装了备用电池这样的安全装置，否则ETS电子 膨胀阀将在断电时，停留在原先的开启位置。 ETS 50, 100, 250 和 400 均配有带湿度试纸的视液镜。 可以通过视液镜来检查阀内活塞的位置，也可以用来 确定系统中制冷剂的流向(ETS 50 和ETS 100)。 同时，通过视液镜还可以观察到由于过冷不足产生的 闪发气体。视液镜中的湿度试纸通过改变其颜色来指 示干湿度。 视液镜和指示器 关闭 步数 线圈 I线圈 II 打开

杆，将旋转运动转化为阀的线性运动。 AST电机外壳有标准配置的玻璃密封的M12接头，同 时也兼容其它特制的电缆和插塞插口连接件。 ETS阀门的活塞为压力平衡设计，能够提供完全一致 的双向流性能以及大致相同的最大能力。 通过过盈关阀使得步数的参考值始终正确。 ETS电子膨胀阀需要一个控制器带动运行，该控制器 可由12V直流电压(5.5W)或100 mA RMS斩波器电流 驱动。 推荐使用Danfoss EKC 316A，EKC 312和EKD 316 作为 驱动器。 注意: 根据控制器或驱动器的类型，阀门传动机构和驱动器 之间的电缆长度会存在限制。 电缆的实际长度，现场的EMC 辐射水平以及驱动器电 路均对驱动电动机的实际电流失真有影响。 对于Danfoss控制器，根据经验，EKC 316A 和 EKC 312 为 5 m 15 feet，EKD 316 为50 m 150 feet。 所有这些控制器都可以在各自的4个电源端子上安装 一个100 mH 的 AKA 211型滤波器，从而大大增加电 缆的长度。 如果您在电缆长度上有任何疑问，请与Danfoss联系。 阀门应用 控制器 / 驱动器 温度传感器 温度传感器 压力传感器 蒸发器 ETS电子膨胀阀 ETS 系列电子膨胀阀 8 为了确保最高性能，需要修正蒸发器能力。选型还 应确保阀门具有可被接受的压降。当过冷度偏离 4K (7.2F) 时，必须修正蒸发器能力。为选择规格正 确的ETS，您将需要下列信息： 制冷剂：CFC, HCFC 或 HFC 蒸发器能力 Qe (以 kW 或 TR 为单位) 蒸发温度 te(以 C 或 F为单位) 冷凝温度 tc(以 C 或 F为单位) ETS 电子膨胀阀最大的可接受压降(以bar 或psig 为 单位) 过冷度 tsub 接口尺寸 示例 当选择阀门时，可能需要对实际蒸发器能力使用修正 系数。当系统条件不同于表格中条件时，需要使用修 正系数。选型还应确保阀门具有可被接受的压降。下 例为正确选择阀门的方法。 制冷剂：R410A 蒸发能力：Qe = 500 kW (143 TR) 冷凝温度：tc = 25C (77F) 冷凝压力：pc = 23 bar (330 psig) 蒸发温度：te = +10C (50F) 蒸发压力：pe = 9.8 bar (142 psig) 液管压降：pl = 0.5 bar (估计值) 阀最大压降： p = pc - pl - pe = 23 - 0.5 - 9.8= 12.7 bar (184 psig) 接口尺寸：11/8 11/8 in 阀门大小 阀门选型 现在选择合适的能力表，按照制冷剂为R410A，蒸 发温度te = +10C (50F)，选择一个在阀门可接受 压降为12.7 Bar(184 psig)时，阀能力等于或高于 435 kW (124 TR) 的阀。 ETS 100在阀门压降为14 bar(略高于12.7 bar (184 psig) 时，提供503.8 kW (143 TR) 的阀能力，并提供 11/8 in 的 接口尺寸，对于本例是恰当的选择。 步骤 3 te C 正向流额定能力 kW ETS 50ETS 100 压降 p bar
