WOW!!!! CRYO-TEK/Chilly1/Polycold Modded Autocascade Rev.3!

And as I said so fare I have much in common with Cryo, so fiew to seriously talk to about any thing technicle here, all my friends just roll their eyes and nod, So both him and I are tech talk deprived! lol diferant fields but hey it's some thing in common, and I've had weirder but increadibly awsom stuff happen! Why not be thankfull that such an expert happend to fall in this forum! Out of all the forums he stumbled accross this one and was happy to see so much about the technology he holds so dear and decided to grace the community with his skill, much like you have (I'm guessing about that part).

I'm sure he'll post more info as he has time, untill he gives a reason to be suspicius enjoy the idea. I too am waiting for a schematic, I'm a patient pony, I'll wait.

Why the hostility? He is a peer and you aut to show him some professional curtisy. (Or at the very least have your info streight)

Well any body with decency (which I think cryo does right now) would not teach people on things he doesn't know exactly what will happen.
I mean, he certainly didn't have to play with meager 150w heatload, he probably didn't use much of 1/4 hp or 1/3hp compressor we use often. Basics are same but actual variation is still unfounded for this small load with OUR configuration (well with good guesses from his end I would think).
I mean, any HVAC guys can build single stage really... but building it well for our use... good luck finding one that even dealt with our situation... (well there are few here I guess lol)
Besides, only thing that is not mentioned at this point really seems to be...
#1 exact charge which will be different for each system anyway.
#2 exact metering amount which again will be different for each system again anyway.
It's for us to start finding out really.
(hopefully cryo guiding us as we come with questions, I know I got my first build nearly perfectly done thanks to you wrdzal and few others :P)

So, I'm a little confused.

Is the polycold an autocascade or a Joule-Thomson machine?

I read it, doesn't explain what argon does, just that it is needed. But I'm now convincid it doesn't do anything under load temperature wise. I think it just helps the gasses to condens and seperate. No helping with load temps

lol, you don't have a clue what my point is do you? and still diss about it :clap:

:toast: Impressive.

@ cryo-tek:

I think a lot of us are wondering what oil is inside the polycold compressor. Some people here who considered using R14 got stuck with oil problems.

Please let us know..

Think u are not following his threads go flip over what he posted for wdrzal its somewhere in there.

to be honest with you Nyx, I am following this topic very close. But all I saw is that R123 is helping with the oil management. But that is'n providing very much info. Or I should simply have missed it, to be honest with you I am stupid enough for that :).

Anyway, if R14 is able to handle the oil because of R123 being there too, how could this information been used in the "classic" cascade system like cold_ice's?

I wonder about the oil too. Since r14 doesn't seem to work in a normal cascade with POE oil no matter what oil seperator you use. Especially because the air liquide site reports that R14 and hydrocarbon based oils aren't compatible. So Guuz's question is a good one. What oil is inside? If it is POE then we can conclude that apparently the oil completly dissolves into the other refrigerants and therefor doesn't react with the r14. We can use this knowledge to build normal cascades with r14.

If the polycold uses special oil this is also usefull because we can search for this oil.

I think its Zerol 150 or a derivative.

Regards

John.

pythagoras you are right.

http://www.xtremesystems.org/forums/...ighlight=zerol
http://www.xtremesystems.org/forums/...ighlight=zerol

As i said he did mention about the oil to be used.

Good morning,

Pythsgoraa is correct, the Polycold units use Zerol 150 in most of there cascades. Telemark Cryogenics uses POE theres.

The job of an oil separate or a phase separator is to separate the liquids from the gas.
The two have the same function. Oil in a hot discharge line is hard to trap. If the discharge line has been cooled the oil is easier to trap. It gets easer if there is a high boiler refrigerant that will mix with the oil.(R-11,113,114,123)

The oil management in an autocascade is easer than in a mulit compressor cascade. In the autocascade, the oil must pass through the phase separators before it reaches the low temp stages. The oil is separated out of the discharge gas along with the condensed refrigerant. The bulk of the oil is removed from the gas stream along with the highest boiling refrigerants in the first separator. (The high boilers need to be miscible with the oil used) The oil mist that passes through the separator is cooled in the cascade condenser along with the refrigerants. The condensed refrigerants and oil are than separated from the gas in the second separator.

I love this but I have to do some real work.

I’m still new at this thread thing, is this the right place to ask a question or do I need to start a new thread? If this is the wrong place please tell me and I will move it

My problem: A new unit that was built has lower suction pressures that the standard units. It also performs better. A new person charged the unit. The rest should be the same but it’s not. What could affect suction pressure?
Captubes
Compressor pumping speed
?
?

Since the question isn't related to the current thread, it will be a good idea to start a new thread. :)

And at what location did you measure the suction pressure?

Don't beat me if I'm wrong (:D) .... but:
Isn't R600 / R600a ~ the same as R-11,113,114,123?
It's rly cheap and easy to get (@ Austria, where I live, you can buy nearly everywhere, where you can also buy some other gasses! ^^ :))

So ... I think nice gasses for an autocascade would be:

R134a / R600a / R23 / R14 / R740

What do you think about this? :)

regards
404Power

:slapass:

R600a is isobutane and has a BP of - 11,7 C

not rele usefull I think

Can u think of a blend for those withouht much cash to spare :D . R14 and argon is way out of scope. What some of us can get is R22 / R290 / Co2 /R600 / R134A and with some luck ethlyene. And those R 4 or R 5 series refrigerants which i think someone say that it is not suitable due to seperation issues. So autoc is really high up the ladder for me to reach for now. But i do enjoy the learning procedure ;). Unless cyrotek comes up with a cheap blend with the above refrigerant which could let us see some -100C action :D

Zerol Refrigeration Oil is a high-quality, synthetic alkylbenzene refrigeration oil.

it comes in sus 150,200,300 nothing special ,works great in burn outs as a solvent. I never thought is was any thing special,looks like milk.

but zerol has a new product zerol ice,its a additive to improve lubercation.

I have a power point presentation. you may need a power point veiwer to see it.

can't upload it.

I wouldn't even know what to ask about such a.....a.........
....a beaaaaaaaaaaast ^^ I'm speechless really :slobber:

man its kinda nice to see some fresh blood that knows alot! most of the time its newbs like me, who dont know jack about this stuff, but its seems like you do know your stuff. i mean even from what little proff weve seen. and if all the other stuff you said is true..... THEN DAMN. im really looking forward to the stuff you cook up for are pc's

and hows that orginal regassed system running right now? saw the -150 screeny, but how bout with loads etc... and can we see some ON chip stuff whith that system???? i want to see how well they OC with it *drools*

cant wait to see what is to come

compressor pumping speed only depends on the frequency of the mains. unless you put a frequency converter in between.


does the unit hold the same load as any other system? is the charge different (amount)? Is the high side pressure lower?

If this isn't Xtreme News, I don't know what is.

Checked the water tower and some one had turned the temp down. My water temp dropped 4c and my evap dropped 8c across the full load curve.
I think I need to look at the sizing of the Aux condenser.

Thanks for the help:D

water cooling tower is pointles here, so humid living next to the ocean, if I where closer I'd do a water to water heat exchanger :D Supamega cold! lol

s7e I have a file you should read. Its a design proposol to cool a ccd chip (evaporator). Its for a telescope but no difference between a ccd (digital camera chip) and a cpu. The head(polytiger/evaporator) with a poly cold will do 510 watts at -150c. It will give you guys some of the techinal dificulty of getting 150c. its a pdf file with pictures and design drawings. problem is its 705kb and the limit is 200kb.

Anyone know how I can post it without spliting it up.??????

try this link

http://www.eso.org/projects/odt/cont..._potential.pdf

The cooling head (coil) is mounted in a cryo vacuum chamber. they are pictured seperate and togeather. pricing is also included :eek:

make screenshot and post?

Here is some recent history of polycold,may help in searches of documents and designs..

It was sold to "intermagnetics" in 1997 and they sold it to "helix technology corp" in 2005

Hmmm...... I know that Cryo-tek has at least one of these Cryo-tigers at his home (he thinks he may have tossed the other one in the garbage :eek: ). This would make for an interesting project :p:

OK, I reread this document and I think there seems to be a bit of a mix-up here ;) After talking to Cry-tek about these "Cryo-tigers" and explaining to him that you had said that the unit was displacing 500W of heat, I was told that Polycold does actually make a unit capable of that......but it would require a PT-1100 (IIRC) Cryo-tiger which has a 10HP compressor :eek: Turns out that these Cryo-tigers don't operate on "true" cascade technology, rather they work on principles more similar to suction line heat exchangers. The unit which is mentioned in the article is actually only capable of removing ~6W of heat @ -150C. The 500W figure is referring to the amount of heat the compressor is outputting. At least that's what I'm getting from this article. Please feel free to correct me if I'm wrong :toast:

no the 510w is the compressor output. my mistake I just skimed it. but


it cools 5 to 7 watts to 95k which is -178C

you should be able to trade capacity for temperature.

just read the hole thread

what a great read thanks cryo

well, dont forget about your ram, we need that running at -150 also you know :D and also the power mosfets.... yes........ *shifty eyes* anything else on a PC that needs to be cooled?

as for the drinks, i think we want them to still be liquad, so you could just wrap the suction line around a drink holder or something, casue well -100 drink is abit to cold....

hehe anyways... back on topic. with auto cascades, would it be possible to fit them into really small spaces and still be able to move about a 200watt heat load at -50 to -100?? such as a small pc in a big case, plus the autocascade?

unknown road is right. The argon won't help, your systems not cold enough. You could try some R13, R23, R503 or R170.

freezing the mosfets wouldnt really do much, they are made to run at over 70c, if you can keep them at about room temp thats enough.

So bekut tried it on his r134 autocascade....hmmmmm interesting.....:wth:

I saw my unit in person yesterday and she's looking a bit "in pieces" :p: Solenoids are really cool though. They'll allow me to each head on and off with a flip of a switch. Nice work Cryo :toast:

no a while a go there was a myth that if you mixed r134a with argon in a single stage you'd get very low temps, it didn't do anything.

hahaha, you lucky SOB :toast:

i've been starting to get the idea in my head that i should build a SS one of these days. might not be cost effective, but it'd be a fun project. building things = happy mark :D

Shall I stick my neck out here and estimate a loaded figure on both evaps?:D

Regards

John.

Professional work Cryo !

Really great ! :toast:

I'll go for -126.3 C loaded( approximately:D ), unless Cryo has been sneeky and installed check valves in the suction side;)

Regards

John.

Thanks for the vote of confidence ;) It's taken quite a lot of convincing to bring the senior members' opinions of cryo-tek around. :toast: But even that estimate may be a bit far fetched as the soleniods are ~1/4A heat load themselves. We'll have to see what happens once the unit is mounted and abused :p:

Single card has always been my preference. I'm no 3d bencher by any sense of the word. If i have to, I'll take my Baker Gpu Phase and mount it on the yonah. Then I could attempt to mount each of these heads on a pair of 7900GTX's. That'll give me -70C on the cpu with -120C on each of the video cards :D

haha then you dont know stephen :D

Excellent work u have done there cryo guy :)
Is there any chance to make a simple photo guide for us?
Perhaps with small compressor like 3/8hp?

Ha you could do a smaller 2stage autocascade tube with a 1/5hp compressor. Its just your not going to have the capacity for a large load.

Be sure to post up some pictures of the system fully mounted and ready to go once you get her, s7e9h3n. I'm interested to see how big the final setup ends up being between system and cooling. :) Have fun with the insulation...
