艾默生膨胀阀(R404A)特定条件下参数

1、艾默生膨胀阀（R404A）特定条件下参数蒸发压力（温度）影响较明显，但是是必须要保证的控制点。选取设计点及一个故障状态（对应不达标蒸发温度及 相应的需求冷量）冷凝压力（温度）在压缩机允许范围内变化时对系统冷量影响较小；但其过冷将大大影响其单位制冷量而影响整体 制冷量，结合现状，固考虑过冷因素。最终既是保证好阀前后压差以及单位质量制冷量。常用系列选型参数如下：R404AT系列指定工况下园的最大窗里将定工脱下闺的最大容量T系列T嘉列ext，equilizerR4O4Axt oquBlizerR4MATT-RO 515B©TURBOS1W 1THR-60SHR® S134 3TH
