I'm really looking forward to see how you fair with R50. Any sort of milestones you plan on achieving or is it just being built in your sparetime.

[ultralo1]

Thats a helluva first post!!!!!!
Great craftsmanship.
Looking foward to more.

[Ozzfest05]

the thread you linked shows posts in 2005 is this a build that is done or are you still working on it.
This is a beast and very interesting choice in refrigerants
What are you planning with the build what sort of heatload

[Moc]

the thread you linked shows posts in 2005

Sun Nov 16 2008 was the day he startet. Not 2005 ;) ...

Good Luck :)

[Ozzfest05]

yeah sorry I was going to edit I was looking at join date I got confused with all the german in the thread lol
but im really looking forward to some updates please keep us posted this looks to be a mamoth project good luck

cheers

[sdumper]

Whats the intended use?

My 3 stage that NoL built for me cold bugged all of my CPU's even with a shim so wondering what your plan for this beast is :--)

[Buckeye]

New AMD Chips have no cold bug :up:

[kayl]

what a cascade this is going to be, good luck and welcome to XS ;)

Are all those thing sin the top right condensers?

[plasmatique]

We are impatient to see working a waterfall 5 stages

Good continuance:)

[bazx]

you just have to love this unit

best of luck rockstar

Q. what is the condencing temp for the R170?

[-EC-UnRockStar]

Thanks,
sry for my bad english :D
More Pictures from the cascade i can show you tomorrow

what do hold you from the Control (http://www.extremecooling.net/index/e107_files/public/1230844487_107_FT47785_touch_steuerung_5stage.wmv) ? ;) :D

E:


Tc2.= -15°C 15,3bar
Te1=-25°C

thus I have at least laid out it then praxis will appear

sorry for übersetzer in English

[BulldogPO]

Very interesting project you have there :)

[s0lid]

5stage Cascade, man that must be atleast -210C cooler :worship:

[Patrickclouds]

-180 is a realistic number.

here is another pic of the suction lines:

Wow man, that is one amazing build! Can't wait to see more pics of that monster.:clap:

[Sam__]

Holy sun of a gun this this is a proper beast!! cant wait to more pics......:drool:

[tiborrr]

Man, that's some hell of a horsepower. I am sure R50 will have no problems condensing if you get the R14 stage right.

[Ant1Xr1st]

Holy s*it О_о
Is it a first 5 stage unit?
How much $ it's going to cost?
Good luck, man))

:welcome: to the forums!

[Simps]

Holy MOLY!

Can the creator please give us some aprox. / est. numbers on:

a) full loaded temps on a high clock with high volts quad core?
b) weight and size of the 5 stager?
c) noise level?
d) total cost?

I know the system is not ready, but please give us some aprox. est. numbers.

[teyber]

hey unrockstar, how bout some pics of that sexy evap you made/ had made :)

[Simps]

I am a noewcomer to phase, I am still learning, but from what I've read so far, this guy must be a phase guru, because I don't think there are a lot of people out there capable of fine tunning a 5 stager correctly. This seems just, very complicated.

[Entsafter]

He's not a guru, but he's a pioneer and crazy :D

[august123]

Man, that's some hell of a horsepower. I am sure R50 will have no problems condensing if you get the R14 stage right.

thats right, but it isn`t easy at all. I`m working on this since few weeks on my stage and in needs much finetuning. R50 is a strange and difficult refrigerant but it is interesting to work with :D

Good luck Unrockstar!

[V2-V3]

WOW, that is absolutely Xtreme!

Congratz on your first post! may there be many many more to come!!!

I believe these are pictures of the Evap he will be using :)

l*b*h=1,60m*0,78*1,50m

[Oliver]

sick man ... that cascacde will push some things huh

keep pushing it

[runmc]

Oh my gosh :eek: How are you going to find a leak in all of that if there is one? Are you pressure testing as you go?

Congrats on the challenge. :)

[Expat GriZ]

I'm speechless!!! :eek: This is going to be GREAT!! Can't wait to see it finished and running!! Don't envy you your power bill...that monster is going to slurp some watts!!

[[XC] gomeler]

Am I the only one concerned about that evap? Even just blasting refrigerant at the base, wouldn't it be terribly inefficient? Why not a beefy maze or stepper?

[-EC-UnRockStar]

The refigerant means are injected into the evaporator Collecting to themselves like with a pot LN2 below. I Having the design electively around later an Capacity regulation to use and to compensate temperature variations

[Wava]

This beast is absolutely the sickest cascade I have ever seen. Best of luck with building this monster! But I also think your evap is pretty inefficient.

[Polizei]

Do I see 7 compressors for 5 stages? Are the blue compressors working in parallel, two for the first stage and two for the second stage?

Are all those blue things on the bottom shelf compressors?

[sdumper]

Fine example of German engineering!!!

[Polizei]

Fine example of German engineering!!!

Now, when you're done with this cascade, lets see some pictures of the BMW/Mercedes/Porsche/Audi. :D

[Moc]

hehe, he drives VW :) !

Nice choice. :up:

[SAE]

Wow. There's some serious work to do. Eagerly awaiting loaded temps when finished. IMHO looks are secondary when creating such a monster. :D

Viel Erfolg, Kamerad! :up:

[Patrickclouds]

@ polizei

there are "only" 5 compressors.
four blue maneurop compressors in the lower level and one rotary on top.
the other black things you can see are expansion tanks to lower the pressure of the stages when the unit is off.

Woops. Scrolling through quickly, they looked like compressors. :)

[tool_462]

That...thing...is...monsterous.

ETA on some results? :D

[piotres]

Seems like those blue Maneurops are very trendy in DE :D. I have one MTZ40 for sale (new) if anybody needs ;) .

I've very interested about results. For sure big MINUS is that cascade can't be bring in any other place :( .

Peter

[tuchan]

Watching and learning........if I can..........from this build!

Keep up the killer work!:up:

[Ultimation]

Insane project. Looking forward to the testphases! Goodluck on building this monster.:toast:

[BoNgWiZarD]

that is one sick lookin machine!! well built and well engineered... cant wait to see this thing in action

and that evap should give you some pretty ganrly performance... with the mix of CH4, Ar and N2 what kinda temps ared you expecting on a real load?? around -180 if you get a good flow rate??

[godmod]

This unit is completely experimental. Expet what you what; what's possible remains to be seen in the end when it is about fine tuning.

I am happy that Unrockstar is building that thing, I am sure, that most of us can learn a lot :clap:

Epic...

What temp/load is this unit build for?

[TheKarmakazi]

I dont know much about phase but this thread is subscribed now!! The implementation and complexity are awesome :up: Cant wait to see load temps on this beast!!!

[teurorist]

most we learned form august don't forget his running :eek: quad stage
but the project from unrcok is real great

[Sneil]

Gah! To cool a cpu lol!

Man for some reason i lost my mojo for phase building. Dont know why but i just keep looking at the $$$$ and ask myself, why!? i need my mojo back, ill keep an eye on this build, maybe it'll spark something in me because this is freaken amazing. Obviously you have some tremendous zeal towards this stuff.:)

btw, as RUNMC said, i strongly urge you to pressure test as you go. cap off the ends after a certaing amount of progress and test, otherwise you'll be in a world of pain my friend.;)


Edit: also personally im not a fan of the evap desing but that's just me. we'll see how she works out for ya:up:

[before]

Looking good so far. :)

[runmc]

What brazing alloy are you using?

[-EC-UnRockStar]

Gah! To cool a cpu lol!

no its for the Northbridge :ROTF:

[sdumper]

Amazing amount of brazing going on!! I pray you never have to track down a leak but im sure your pressure testing as you go.

[EXPANDER]

Good project.

[jasonelmore]

Awnser some damn questions haha :) j/k

Massive ammounts of copper. that baby is going to take 2X 220 outlets to run haha

Good stuff.

YIKES!!!!!:shocked: Keep progressing Mate!! Heck, If you are accepting interested spectators I'll drive to Germany just to see this BEAST in action when its completed!! It has been asked before, what kind of Load Temps are you anticipating??

[[XC] gomeler]

I don't know what I'm looking at but I like it. It's like in 60's movies they'd show rows of blinking lights on computers. Don't know what they mean, but they sure look cool.

[teyber]

i think the cascade will be controlled via a touch screen computer?

[Ozzfest05]

I wouldnt be surprised if this was controlled by touchscreen infact he might be making this into a transformer and it will drive its @ss on over to its owners house
Mad respect this looks like such a huge project

[-EC-UnRockStar]

The Cascade will be controlled by the Simatic S5.

The Touchscreen is only the Operator Panel ;)

The Cascade has 30 PT100 and 10 Transmitter for HP and LP

[Moc]

I asked him if he was pressure testing as he went along and I also asked what brazing alloy he was using. :)

Major respect to you -EC-UnRockStar for under taking such a massive project. :up:

I'm sure he uses Silfos 15 (15% silver) and 45% silver brazing rods.
In our forum, he wrote that he will pressure test when all stages are brazed.
But I doubt that there are leaks....:up:

[piotres]

What is role of those thicker pipes brazed before TXVs inlets ? :rolleyes:

mother of god what part of the planet are you going to freeze first lol

suscribed this looks good nice workmanship !

[godmod]

What is role of those thicker pipes brazed before TXVs inlets ? :rolleyes:

hmm, let's think, maybe receivers?? ;)

[-EC-UnRockStar]

right :)

[piotres]

hmm, let's think, maybe receivers?? ;)

Well I guess that was sarcastic, I know that before TXV people often mount receivers, but I have always thought that in receivers inlet should be at lower level that outlet - in way like Unrockstar did it, how it can accumulate any liquid ?

[Moc]

lol! The outlet should be at the lowest point. How can a receiver accumulate when the the output is on the top? The TEV need liquid refrigerant.
Get a refrigeration book, there are detailed pictures...

[Kepons]

lol! The outlet should be at the lowest point. How can a receiver accumulate when the the output is one the top? The TEV need liquid refrigerant.
Get a refrigeration book, there are detailed pictures...

But this way you aren't sure if you are supplying the TXV with onlky liquid refrigerant. I think i know what Piotrek means and i think the same.:up:

[Patrickclouds]

the outlet is on the lowest point.

if you buy a receiver there is also a standpipe which goes to the bottom of the receiver. this often ends on top of the receiver because of the rotalock to make the pipes at one point lockable.

so i don´t realy understand where you see any problems.

[godmod]

Piotres after a bit of thinking i know what you mean. But after all the inlet is on the top side and the outlet of a receiver is on the bottom.
You mean that in this case there is the danger that the gasous and the liquid wont unmix/seperate, do you?

[Moc]

It's better than nothing.
If he wouldn't use those small receivers, in idle the plate HX would fill with refrigerant and this "removes" surface for condensing.
To bad there are no sightglasses for -120°C @ min. 20bar :D , he could show use that it works.

The only stage that should ever have absolutely no load in normal operating conditions though would be the final stage with the direct-die evaporator.

I enjoy looking at this build in the same way I enjoy looking at people build huge skyscrapers. I don't quite recognize everything but it's still awesome to look at. Need shots from further away so we can trace piping and understand what is a compressor and what's an expansion tank :D

[piotres]

Yes maybe at start I wrote that in bad way, I mean that outlet IMO should not be at absolutelly lowest point like it's ..becasue from mine point of view those acumulator doesn't acumulate anything, refrigerant will just go too fast to pipe after receiver .

Look at chilly1's drawing of receiver on this scheme :

peter, those receivers have a tube inside to the bottom, it's only on the outside that it looks like that.

or do you mean something else ?

[Sneil]

grtz

The reciever still has to accumulate liquid before it can exit the tube. Not so in -EC-UnRockStar's, it just acts like a wide tube which the liquid quickly flows through. I get what he's saying, but im sure -EC-'s way will work fine, just not function exactly as an accumulator should.

[aenigma]

It isn't an accumulator, it's a receiver, but I think that was just a typo. His way will work fine, exceptional really and I will get to why soon. First off you must know a receiver's purpose is to add internal volume for liquid storage so it doesn't back up into the condenser under varying loads. There isn't any secret science behind it or anything, so any old design will usually work fine.

On the other hand this is where his design is great and seems to be thought out very well. A standard receiver has a pickup line at the bottom which requires the large receiver to fill enough to get a liquid seal on the liquid line, which means extra refrigerant is required. But with his receivers the bottom of the receiver doesn't have to have enough liquid before the liquid line pickup starts picking up liquid, and that is great for a cascade. The less refrigerant the better the static pressure. Keeping the area on high side as small as possible, especially on the liquid line, is a good idea and good practice. Although it probably isn't required with his large expansion tanks, it's still a good idea.

Awesome project too, it is looking awesome, you've got too much cool stuff!

[FFlegend]

Awesome work man, really xtreme!

Why would you need that much wiring to run this?? I hope to god u don't plan on hooking this thing into the powergrid:nono:

[fubarswe]

I am speachless.., never seen anything like it.., turning powerswitch and belsebub will emerge in vapors... :-)

[mike8913]

this is just silly

[thenrz]

Looks like you plan on running this thing pretty much automated. JUST INSANE! You've got the opposite of add my friend.

[sdumper]

Backup power,starter components, fans, temp display ect...
Still it seems like a ton of electrical for just 5 compressors

[teyber]

correct me if im wronb but hes setting up a controller via a computer i believe, hence all the complicated electronics

[biglipzit]

Holy wiring batman!! I am speechless.... Looks like some generator automatic changeover boxes I have worked on already....

MOST EXTREME PC COOLING IN THE WORLD

I nominate for a new catagory

[Evil_AnAnAs]

Makes my modded mach 1 look like a heatsink...

I ask again, what temperatures are you aiming at?

[Patrickclouds]

he is going to use argon in the 5th stage.

so i think temp should be around -180°C :D
in darts it´s a tripple 20 and they say "one hundret and eighty" :D

[mike8913]

using a computer to control a cooling unit to cool another computer. . .

definitely xtreme, amongst other things.

you could set up a small tablet pc to mount by it to control it all

I would also like to see some zoomed out shots of the unit. Just to get an idea of the size :D

isulating the Suctionlines from stages 2-4
piping the first stage ..

Big congrats!

Man, I hope you can achieve -200C!!!!!

[Buckeye]

Looks fantastic !!

Question tho. From the first pictures it looked like you had 3 of the big blue compressors on the bottom all lined up. Now it looks like you have removed 1 or moved it someplace.

[Patrickclouds]

the first stage compressor is dead. the crank doesn´t move anymore. he is going to replace it.

here are pics of the dead one:

maybe not reach 0K, but with a bit of pressure, and some He :D maybe to 10K :welcome:

do you know cause of death (Dr :P )?

[barbus]

Hi, I just love the size and complexity of your build! very good.
A Maneurop compressor in bits, seen plenty of them whilst fault finding. Most failed Maneurop I come across all die due to poor superheat, they seem to be very sensitive to it causing either lack of oil or dilution which ultimatly causes lock up.

[runmc]

Are we waiting on new compressor? :)

new 1st stage compressor has still arrived ;)

now he is insulating the pipes
doing some electric work, installing the temperature probes, ...

I'd hate to see your electric bill.

[teyber]

I don't know what the displays are saying, but I'll have to agree with the "Uber" that was onscreen :D
Question: Is that -80 measured in kelvin?

Real Question: what are your temps at each stage? Sorry, I cannot tell from the images :(

well that would be somewhat of a scientific miracle :rofl: jp mate, also there is a video in the previous post. he links at the bottum of the post :) :up:

[Duh]

I saw the video but couldnt see the lowest temp achieved by the moster

[Patrickclouds]

we only started 1st and 2nd stage

[Ozzfest05]

I am afraid of this unit I never go into this thread past sunset or I wont sleep at night!

[dinos22]

what sort of a budget do you have for this project

amazing stuff indeed :)

[-EC-UnRockStar]

roundabout 3000-5000 € material

You mean unglaublich and YES this is some insane build!

[-EC-UnRockStar]

18.5.09 i will Refill the 3rd Stage with R14 and i think i can do a testrun on Stage 3 and Stage 4 (Stage4 is filled)

[tiborrr]

Fantastic, UnRockStar. Waiting impatiently!

[eligray]

any updates man? :)

[exemay]

this is INSANE, i wouldnt like to think of the build or running cost of this.....wow

cant wait to see more

[lalPOOO]

Just remembered why I love this XS. Amazing craftsmanship, can't wait to see this on a cpu.

[Snot aap]

This thing is sick.
Waiting for updates. :D

[HenrikW]

Looks utterly insane... I love it :) Please keep us updated ;)

[teurorist]

have a look

What were the final temps on this unit? I am still amazed at the quality of work!!

0 Kelvin is absolute zero ;)

I can't wait to see this cascade finished :)

[Patrickclouds]

new pics are postet here: http://www.extremecooling.net/index/e107_plugins/forum/forum_viewtopic.php?47785.340

he has dismounted the condenser in the 1st stage zu finish insulation job.
and the computer for the electronic control has been installed.

[tiborrr]

Damn, it's past midnight - no sleeping for me :shrug:

Again I am skimming the whole thread. Fantastic job, mr. UnRockStar! :up:

[eligray]

lol @ the fact that a computer controls his computer cooler :)

I can't wait to see final temps. I want him to condense LN2 unloaded :D

[Duh]

Dude could you please post some of the pics with some description in here? My german is very primitive (very) and I am sure many would be delighted

[sdumper]

Was this build finished and posted somewhere else I cant find any links to the current status so wasn't sure.

[august123]

such a giant build takes a lot of time thats all ;) My 4 Stage Cascade isn`t completed 100% since almost 2 years, if you do this for hobby there are limits in time, money and so on.

I`m sure he will post some updates soon.

[-EC-UnRockStar]

I have Cleaned up all Pipes and add some parts on the rotary for the last stage.

The compressor in the first Stage is damage, the internal Safty Valve Leaks and produce a hotgasbypass.

i Waiting for a LT50 from august.

[Duh]

I don´t even understand the basic working background . I am just a watcher that liks the over all of the process and the frost itself :cool: . Of course watching german and american craftsmanship is completely stunning.

I understand such a monster must be done bit by bit and calculated but sometimes anxiety makes you do stupid things like submiting a thread like mine asking for more :D. I recall your build but can´t understand how comes 2 years have already taken place :S

[teyber]

the small details take up so much time. when you are trying to do something and spare nothing like august, a days work can go to something like cleaning pipes et cetera and how often do you have a days work to work on something ;(

[trance565]

just ..... wow

[Duzter]

Looks good m8! :D

A thing I'm worried about is you using AKV valves with plate HXs. Have you mounted a "filter" after the AKV valve?
I have learned that plate HXs don't like the pulsation from AKV valves.

[-EC-UnRockStar]

Today i will build in this Bitzer Compressor in First Stage.
V=32,5m³/h t0=- 35°C /tc40 Q0=4500W

What a beast :D

Was there any reason you took the endplate off? Or were you just curious?

[SAE]

Seeing this beast I'd never have guessed that it's a compressor at all. :D

[-EC-UnRockStar]

Yesterday and today i have switched the compressor in the first stage :

big stuff .. do you move all those big stuff only by yourself?

What happened to the big first stage compressor which you opened to check? I could not understand if it was ok or if it was damaged.. you will make history dude FTW

[-EC-UnRockStar]

Yes i move it only :D

i Opened The Compressor to check the Piston s and the in/outlet Valves and the winding.

The Old Compressor in the first stage is damaged

[Duh]

The Old Compressor in the first stage is damaged

:banana::banana::banana::banana: the olde big one? which one is the replacement? are you a mechanic engineer or just nuclear physicist ?

[v0dka]

Wow, this is like having an endless supply of LN2. Or better even. This is amazing. Really cool stuff. :yepp:

[-EC-UnRockStar]

The NTZ136 is the old damage compressor

the Semihermetic Bitzer is the replacement.

i´m a Refrigerant plant builder.

[s0lid]

If that were a woman i'd marry it. :rofl:

Lookin good :yepp:

[apt403]

The Ln2 Cooled SS is build by me ... ;)

Is there a build log for this?

[eligray]

Looks amazing :)

is the -148c from the 4th stage?

[Bonkers]

So... how many Megatons?

Waiting anxiously for tests on a CPU

[-EC-UnRockStar]

Is there a build log for this?

No the SS is build in ~1h


Looks amazing :)

is the -148c from the 4th stage?

Yes its the temp from the 4th stage.

i need more R14 in the 3rd stage

[tool_462]

:shocked:

Best I could come up with.

[Duh]

No the SS is build in ~1h




Yes its the temp from the 4th stage.

i need more R14 in the 3rd stage

go and steal some from the fabric you work at (I m joking)... your build is simply awesome..

[-EC-UnRockStar]

We doesn´t have R14 at my work... = (

[Hampti]

Do you know anything about your target temperature? How deep would this be?

[Patrickclouds]

about -180°C to -185°C

because argon gets solid at -188°C

maybe it is possible to use Nitrogen in the 5th stage, then he is going to rock the -200°C wall :D

[Turrican]

wow, so who need ln2 then? :D

i guess this cascade is for sure very expensive too. ;)

[SAE]

Naaa, it's one of the cheaper ones. ;)

[tiborrr]

UnRockStar once said (in some other topic) that this cascade costs about 8-10k € just in parts. That's a resell value of about 15-20k € I think :)

Waiting for progress, mr. UnRockStar! :yepp:

[sdumper]

Tiborrr did he build this under contract for someone or did he just do it for fun.
Thats a lot of money and in the US would buy a car.

[eligray]

I can't imagine that this would have been under contract, it's just too big and experimental of a build.

Besides, we know that he likes doing crazy projects; he built a LN2-cooled SS :D

$5 says its just a personal project :)

If that true I feel sorry for his wife :)


No wait I feel sorry for him because if his wife is like mine she will be all over him for spending the money.

[Knight]

From post 178:

roundabout 3000-5000 € material

Maybe it has increased since that point in time, I don't know. :shrug:

But one cool project. :yepp:

[-EC-UnRockStar]

increased because a Compressor is damage and i build a new Controll

[-EC-UnRockStar]

New Colour:

[eligray]

Looks a lot better than it did before! I think it looks good to have an unusual color (orange) in such an incredible project.

Do you still need more r14 for third stage?

Is there a HP rating for that orange compressor?

[-EC-UnRockStar]

The Compressor is Red not orange =)

He has round about 15HP/11kW

[Kartoff]

Verry nice looking :)
And i think red is a good color regarding blue others...

[Foamy]

That's a very old plc, i hope it can stay stable :) (S7 ftw!:D)

[bartx]

I can't imagine here leak testing, when I've got problems in my small SS unit :ROTF: But if you're good in brazing and have some leak detector tools it should be a big problem I think. Waiting for finish :rolleyes:

[-EC-UnRockStar]

the Only leaks i have on the cascade were the damaged pressuretransmitters -.-

[piotres]

He has round about 15HP/11kW

Won't it be too weak ? :rofl: :ROTF: :p:

[-EC-UnRockStar]

a little bit ;)


Hp 2nd stage 6bara with R170 (ethane) condensingtemperature ~ 48°C with 4 running Stages :D

[Hampti]

and what do you think... when can you start the engine^^ or better the Kaskade will be finished? i'm very interested what you can reach with this monster.

[Patrickclouds]

there has been a lot of electronic work before the cascade is going to run.

[-EC-UnRockStar]

a "little" bit

[RyderOCZ]

I don't want to pay the power bill to run this thing :ROTF: :up:

[SAE]

I think his town's lights would dim as soon as he started it. :lol:

[-EC-UnRockStar]

The Cascade need round about 16kW per Hour with running all Stages :D

[SAE]

I need that thing - it's THE weapon against the "green guys". :bananal: :shock2:

^^ It ensures nuclear powerplants do not get futile. :lol:

[sofos1990]

The Cascade need round about 16kW per Hour with running all Stages :D

WTF???:rofl::rofl:
I'm so curious about the cost of this beast:D
What temps are you aiming for?:up:

[eligray]

Dam, from a rough working out via Google on the price (way out i think) thats gonna cost me £15.90 per hour too run!

16 kilowatts = 16 kilowatt hours per hour * .13euros/KWh =

around £2 per hour :up:


Cheap, if you ask me :yepp:

[[XC] gomeler]

16 kilowatts = 16 kilowatt hours per hour * .13euros/KWh =

around £2 per hour :up:


Cheap, if you ask me :yepp:

Yeah, cheap compared to LN2 costs.

[gosmeyer]

WOW-I've got nothing :D Hell, i'll be honest and say i cant even follow the pluming. This forum is an amazing resource:up:

Tell Georgia Institute of Technology to take a peak here:rofl:
