Re: Pressure drop through the suction line accumulator?
Interesting drawing, looks like a oil recovery bottle on a flooded ammonia evaporator.
If not ammonia, could be anyones guess.
I can see why you have a 2 bar delta P from evap to compressor, with 3/8 dry suction.

Re: Pressure drop through the suction line accumulator?
OK, I went back and read the original ost again, its R134A. Could still be a scavenge oil recovery line that rises up in vessel to control level, the 1/4 "line would restrict flow and limit it. Also the 3/8 dry suction may be intentional to restrict carry over.
What controls liquid feed to flooded evaporator ?

Re: Pressure drop through the suction line accumulator?
dunno here we go years ago came across this sort of cascade system and i reckon that something like this was used on the expansion recovery,over run what ever circuit,come suction accumulator what ever to keep the feed up to the refrigerant pump.must say it was a little bit bigger on sizing but.ammonia blokes should have an idea
anybody else good for ideasmmm to beer or not to beer...........lets drink breakfast

Re: Pressure drop through the suction line accumulator?
The 1/4 inch pipe you mentioned is usually a support pipe . I have in one instance noticed that one of the pipe tilts if you test the accumulator indepedently . So to my knowledge it is a support pipe . Just check with manufacturer . Besides, give me the following data to select the right model for you to compare.
Refrigerant
evap capacity
condensing temp
evaporation temp .
