Suction Accumulators
Whilst estimating the holding capacity of an Accumulator, is the entire internal volume of the accumulator considered or about 75 to 80% as is normally done for a Cylinder? The volume would be multiplied by the density of the liquid refrigerant at the evaporating temperature, I presume , to arrive at the weight of the refrigerant.
I would like to know if this assumption is correct.
Also, the weight calculated as mentioned above would be about 50% of the refrigerant charge inthe system, as recommended in most manufacturer tables. Some manufacturers talk of 65 or 70 % . What would be appropriate and what is the rationale behind this percentage factor?
