Hello,
The little self contained water chiller I am building needs a suction accumulator.
Ideally the suction line will be 3/8" OD, however the most appropriate suction accumulator I have found (going from the manufacturers tables for refrigeration capacity, pressure drop, oil return rate) has 5/8" connections (and presumably 5/8" internal U-tube).
This would give a much lower vapour velocity than the suction line.
My question is:
- Is seperation of the oil from the refrigerant a problem in very short lengths of vertical line (i.e. a few inches) or is it only a problem in longer pipes?
Cheers All,
James.
