Any updates?
tnx
i dont understand y u guys dont run the cap lines inside the suction line at the and of it....
coldy u didnt replay to my pm, at least tell me yes no...
ciao
because you get more surface area by wrapping the cap tube around the outside of suction line.Quote:

restriction my friend:)
And some times,,, with flexes... it could be pain in the arse to braze... As for surface area for wrapping around, I deem it even as inside means you get full cooling for the length. How much cap tube really touch when wrapped on suction? Besides, for remaining length, you can still wrap it around to rest of suction. The real problem would be depending on tubing size, restriction as JORT said, and another would be the fact design might be painful to maintain, change, etc. I've seen quite a few using cap tubing inside suction line working fine (bit oversized suction to begin with so restriction was not even an issue).
No updates yet. I'm still waiting for a better quote for the R14, because 500€ for 6kg is too much. I hope that I can make a good deal this week.
Good luck with your search. Any croygenic refrigerant seems to sell around price you are talking about after my exhaustive search... kind of bites. Probably due to lack of market size.Quote:

worth a try
i always thought pc-ice used a r1150 / r50 blend in his third stage,Quote:

pure r50 is a pain to work with.
but i made a mix of r50 and r1150 and this is what i got.thats all i did.. :)
I don't think r50 and r1150 make a azeotropic blend so I doubt if the load temp will be much better as pure r1150 but you can always try it out. hard to say.
Looks good, when it worked for pc_ice why shouldn't it work for me too. I will try it for sure. Hope I get as good temps as he had.
well I would definitly give it a try but I'm afraid that when you put a big load on it the methane will evaporate leaving the ethylene liquid in the HX (too cold for the ethylene to evaporate) but when there isn't enough methane in the system to remove the load the ethylene needs to deal with the remaining load but it only starts to evaporate at higher temperatures, so temps will rise untill that point is reached. So I think the load temps will only be slightly better as with pure ethylene, depending on the amount of methane you can put in the system.
Offcourse this isn't an 100% accurate discription of what is happening in the system, but that doesn't really matter for the proces I'm trying to discripe.
I hope you understand my reasoning.I would certainly try it out because I'm not sure of it blends or not. If it blends well you can completly forget this post. :lol: but when it doesn't blend I think what I discriped will happen.
A bit colder and you could use nitrogen in the final stage. lol.
(that was a joke for all you ppl who cant figure it out)
I hope it will blend, if not I have a problem as you described.Quote:

I tried an ethylene/methane mix in my third stage too, idle temps decreased a bit, but it didn't hold any load correctly, I figure that unknown's explanation describes very well what happened to me :)
How much ethylene and methane (%) did you put into your 3rd stage? Did you use an expansion tank?
maybe your methan (not so pure) , no ?Quote:

Now imagine what would happen if you broke the neck off of a bottle like that :slap: :D
you'd have a very nice missile (I know hehehehe. (Only it wasn't methane))
Be very care full and FYI You NEVER should leave a cylinder free standing like that!
Chain n Restrain!
Think of it like a woman on her period, both are serious flaming missiles.
^Sig material right there :)
The metall-cap is on the bottle so I don't know about what you are worried about.
mmmm
yummmmyyyyyy
take time to finish it cause are stressed everywhere....
