The valve is stuck in mid range: This is usually associated with a contaminated system. The evaporator will
have a poor temperature drop at extreme operating parameters therefore there is inadequate refrigerant flow at
high heat loads and excessive refrigerant flow at low heat loads (coil flooding).
The valve is stuck wide open: This will cause excessive refrigerant to flow into the evaporator coil. The coil will become “Flooded “ with liquid refrigerant. The result will be poor temperature drop because the refrigerant is not evaporating in to a vapor. Because the expansion valve is wide open the suction pressure will be higher than
normal and the return line will be very cold because the liquid refrigerant is evaporating in the line instead of the
evaporator. The discharge pressure will be lower than normal because there is very little pressure drop across
an open expansion valve. There may also be bubbles in the sight glass under this
condition.怎么翻译?谢谢前辈

乱翻的
活门（的开度）卡在中间位：这通常与系统变脏了有关，蒸发器在极大的参数设置下却只有很低的温度下降，因此当温度较高时（蒸发器里）会有不足的冷凝剂流量，而当温度较低时又会有过量的冷凝剂流量（蒸发器蛇形管里液泛）。
活门卡在全开位：这将使过量冷凝剂流入蒸发器蛇形管里，蛇形管将“洪灾泛滥”充满液态冷凝剂。结果将是差的降温因为冷凝剂没有蒸发成蒸汽。因为膨胀阀位于全开位吸入压力将比正常的大，回流管将会很冷因为液体冷凝剂在管中蒸发而不是在蒸发器里。出口压力将比通常的低因为通过开着的膨胀阀几乎没有压力下降。观察窗里也可能会有气泡在该情况下。

看样子要用翻译软件了
