Liquid floodback

[A.Mortezania]

Dear All,

In all of sources we see that for example 10% of end of evaporator (+ Suction line) is called super heater and it means when refrigerant comes out form evaporator it should be in superheat position on PH diagram.
But at low temperature evaporators even by using proper expansion valve and proper heat transfer area on evaporator and proper fan, Twice we have liquid floodback. This is one of reason that most of companies make accumulators for prevent liquid floodback to suction of compressor.

"I Think at low temperatures, If we do anything we can not prevent liquid floodback form evaporator and we should use accumulator to protect compressor".
It is true or even by using proper evaporator and proper expansion valve even at low temperature evaporators we have superheat at end ?

Sincerely yours.
