Some oil still circulates in the system. And you would not want that to stay in the accumulator.

Why is the reciever for the first stage so much bigger than the one for the second and third stages?
In the first stage we need more gas becauste a small fluxuation in the third translates to a larger in the first. Also we need to minimize the total system charge in the second and third stages.
how many inches of 1"" pipe would you reccomend for the recieveer on the low side?Quote:

I use a 1.5 inch OD pipe and two pipe caps the pipe is 3 inches tall and the outlet is at the 1.5 inch level.
i really want to learn all this stuff about what each part is and does etc and how to build one, are there any good websites or documents explaining it all? or would it be best to just keep poping in and out of here and learn things over time?
Read the stickies, there are links there on where to go to learn more. Buy Gary's book.
talking abount garry
he's not around as much laterly has anyone heard form him?
hes missing all the cold action here
Gary is very busy at the moment. I got the impression hes got some personal stuff to take care off.
But he said he'd be back as soon as he could.
what gases could be used in a cascade low stage that dont require the use of high pressure cut off's?
Non that are worth the effert of making a cascade.
what about r507 and r404a for learning
then maybe later the good stuff.
what safety devices are needed in a cascade
pics please someone and/or a drawing
The infamous three stager......
Why you deleted the labels??Could you pls put lebels on the tristge???Pleeeeeease??
Question: Where can I buy Gary's book? and What is it called? Thx.
Titled tristage with additions.

I think I get this now. and again, good job!!

For a starter, in cascades, what gases can we use in first place to test our work, and what temps can we anchieve with them?
Do we really need an accumulator, or can we do a coil (what size +-?) with copper tube instead? (sorry if this is explained earlier, but I can't understand somethings)
Do we must insulate accumulators and oil separators?
Best regards!
suctions hx are essentialy?
I don't think so, but they improve the subcooling :)
Another question, what is the minimal compressor power for a cascade ? I was planning to make something out of two 1/3HP compressor, but I don't know if it will be enough to cool a gpu ;)
In cascades I think they are..
HX=Heat Exchange?
Also instead of using an accumulator, to boil off any remaining liquid in the suction line returning to the compressor u can wrap some copper tubing tightly around the compressor's shell to help cool it without having to worry about it sluging liquid.
