4 Stage Cascade by august123

[august123]

Last October I started planning my new cascade.
First I wanted to build an 3 Stager, later I decided to build a "really" 4 stage cascade with sould hold about 200-250W at -160°C. I hope to come in this regions with this build, we will see.

Main Compressors are Danfoss/ Maneurop Reciprocating Compressors, I get them for good prices.
Everything is mounted on an steel construction, weight of all together is about 200kg I think :D Dimensions are 1,3m x 0,75m

On this picture are the temps with actual tuning, freqency converter for extra power in first stage. T1 is condensing Temp from R23, T2 is evaporating Temp, T3 is condensing Temp R14 and T4 is the evaporating temp at the plate HX. :cool:
(need to adjust TXV in second Stage a little bit more, to get compressor ice-free)

http://www.extremecooling.net/index/e107_files/public/1204982452_119_FT31681_dsc_4545.jpg


two of the electronic temperatur controllers, they start each stage automatic when temperatur is deep enough. Need to make nice control panel for them and the Build- In Manometers.

Holy.. good job :up: Very impressive, what load are those temps at?

edit: nm, I assume the 3rd stage temps were unloaded? Damn nice man, R50 will be wicked, want to see some "suicide" shots :)

[before]

Looks very impressive... :)

[t800]

looks very nice...u have "few" wires in electric panel :P

[DagoDuck]

This project is AWESOME. Keep up the good work, my friend!

[runmc]

Excellent build!! :shrug: It is a pleasure to have your build here to study. :welcome:

Your work looks very clean and organize, not cluttered and dangerous looking like some. :)

[7499richard]

holy :banana::banana::banana::banana: that is so sick looking man.....it must sound like a jet engine, and literally not just a figure of speech lol

wicked project and awesome work.

how do you like those Allen Bradley terminals, I work in automation and work with those a lot, as well as Phoenix terminals, I find the Phoenix much nicer to work with.

[kayl]

go hard or go home hey :up:
thats going to be a mean cascade :welcome:
so whats going to be used for the refrigerant in stage 4, methane or methane/argon blend??

[godmod]

It is going to be R50, Methane.
Really nice build.

[Clemmaster]

"MT and MTZ compressors have a large internal free volume that protects against the risk of liquid hammering when liquid refrigerant enters the compressor. MT and MTZ compressors are fully suction-gas cooled. This means that no additional compressor cooling is required and allows the compressors to be insulated with acoustic jackets, to obtain lower sound levels, without the risk of compressor overheating."

For those like me who were hurt seeing this :
http://www.extremecooling.net/index/e107_files/public/1204466777_119_FT31681_dsc_4426.jpg
:p:

Impressive work and very nice compressors you've got there! Second stage seem a bit overkill with only -75.5°C evaporating temperature don't you think? Don't you think you could also switch 2nd and 3rd stage compressor to get benefit of the 67ccm for a gas with high specific volume like R14? In every case this beauty may work like a charm :)

Can't wait to see this beast loaded!

[SoulsCollective]

Needs moar jiggawatts.

In other news, if I pledge my soul and first-born child, can I touch it :p:

[heanwi]

Good look transporting it to LANs and other events! :P What a mean machine...

[teurorist]

my hope is in the last stage 400V 3~ rotary :D because then he can use a frequency converter to change load temperature on the cpu

[Sneil]

Holy crap! That is one beautiful piece of work! That is one hell of a build, im sure this would have cost you close to 10Gs!!:eek:
Looks like you're an electrician too!
Amazing!:clap:

[toaster]

nice :up:

[Pete]

This is wild and crazy but so cool. Amazing work and some real skill been put to use here. Dread to think what it has cost but well worth it.

Not tempted to try and expand on it and get LN2 temps?

[Marvin]

impressive. Awesome.
congrats

[4Qman]

Are you implementing any features to allow control of the temperatures for Cold bugged CPU's ?

Oh and awesome work. Very skilled indeed ;)

[quintus]

''4m flexline + CPU Evap''

and i tought that you will have at least 4heads:D

succes,
q

[godmod]

Why would you want to use a 4 stage cascade on a cold bugged cpu???

[teurorist]

Because i think its more impressive to use a 9650 then anny a sokel or a old Intel but i also think it's a lot of fun to bench non cold bug cpu's

[Felipe]

lol!! 11hp cascade xDD

[n00b 0f l337]

Whoa 11hp? Wee inefficienct?
One of those maneurop in autocascade could hit your goal...

[jimmyxxx]

Holy **** :shocked: , 6000W @ 400v, dam having that thing on for 3 hours should be very expensive.
11,5 HP :eek2:

[[XC] gomeler]

Why would you want to use a 4 stage cascade on a cold bugged cpu???

Well I guess you could spend thousands looking for a cold-bug resistant chip. There are a few that seem to be able to handle more cold than others. It's going to be very interesting seeing what this thing can accomplish. I fear though it may actually be TOO cold for our uses :( Good thing he's got a frequency modifier but his first 3 stages would already be overkill :cool:

[godmod]

One of those maneurop in autocascade could hit your goal...
Please proove that ;)

[teurorist]

may anyone have to say he start building before he have build a real 2 stag ore 3 stage :D but he plans the project perfectly
for cold bug we hope for a 400V 3~ rotary with frequency modifier
for fast melting the evap the cascade becomes a hot gas line hopefully with an hot gas control valve
and whats with little copper plates ;)


Please proove that ;)
Me toooo :D

[Clemmaster]

Useless and what about safety? Is there any need to do that when a "normal" cascading system can achieve what he aims at?

[teurorist]

i think he built it saver than someones 2 stage :D
and i can often see the system and learn a lot of it more than i can learn from a 2stag

It is about building such a thing I think.

[Noob-ftw]

Please proove that ;)

Ohhhh, NoL will prove it; just wait a bit. :)

Back on topic:


That cascade is very impressive, I'm sure you've put a lot of work into it, and it shows.

[Oliver]

Impressive work, really a good job there for sure...

I like it, i like it really much...

Looking forward to further updates and numbers...

Keep building it...

I have to add that you are totally useless.
Think about whats useful and useless here, what is efficient and what not, what is worth the effort and what not. We all are doing this becaus we like it and not because it brings us money or beacuas it safes us something like electricity. therefore i have to say that your comment is absolutely dumb.

[i hope that i understood your posting right.]

edit: i cannot see yomething unsafe at this build.

[[XC] gomeler]

It is about building such a thing I think.

Agreed.

This is like slapping four huge turbos on a 454 cubic inch engine just so it'll push 50 PSI from 5500RPM to 6500RPM for a Dyno chart :D Who cares that it's in-operable below 5000RPM and impossible to use for any normal application.

[teurorist]

we are germans we have no speed limit :D

I'm talking about 1st stage autocascading, not the cascade like it is now :rolleyes:

This cascade is impressive, 1st stage autocascade is useless with those monsters and the gases he's using.

You're absolutely dumb too :up:

Maybe you should use the quote function. Then everybody would know who you are talking with or what you are talking about. In this case there was no relation between first stage autocascading and your post.

[lukas69]

Amazing Cascade :shocked:
how many Watt need ?
-160 is near LN2
great work

[Solarfall]

OH sweet jesus that thing is a freaking monster... :eek: really nice work buddy :up:

For tempresure adjustment he is going to use a frequency converter to slow dow n the last compressor. As far as I know also a hot gas bypass valve from danfoss will get into the last stage.

-160°C at the evap isn't in your CPU ;) you know the big delta T between Evap and CPU.

But while planing this monster, I also said that a 3 stager will be way more usefull and efficent.

[n00b 0f l337]

Honestly I know what hes about though, screw efficiency its going to be sweet for sure.

[nachthymnen]

What a beast!:eek:
Amazing work:clap: :up:

[TopherTony]

if you can build a solar farm to power this, you got efficiency

you can buy a dixell xt110 and you have a thermostat which works down to below -100 with a pt100 probe.. cost about 70-75euro+probe..

[[N@irolF]]

Hey August,

congratulations to that extremely well-done stage!
This one is one of the best processes i've ever seen!
I really wish that this monster will work in that way you used to dream of :rolleyes:

:up:

[godmod]

I did not calculate it myself, but I trust the calculation:

4th stage 315 W at -160°C
compressor size 20 ccm / 3,48 m³/h
Max. motor power ~ 585 W
Max condensor power ~ 900 W
COP ~ 0,54

sorry, I don't know more e.g. superheat or something...

In few weeks we will see how it works out :)

[M.Beier]

Outstanding... :|

[dinos22]

talk about having some muscle :D

good luck with your build man :up:

[Clemmaster]

I did not calculate it myself, but I trust the calculation:

4th stage 315 W at -160°C
compressor size 20 ccm / 3,48 m³/h

Max condensor power ~ 900 W
COP ~ 0,54

sorry, I don't know more e.g. superheat or something...

In few weeks we will see how it works out :)

Qv = (P / (h_gaz - h_bub)) * Ug (*3.6 to get m³/h)

For -160°C captube end, -145°C out, 20°C suction temperatue you get
Qv = (315 / (705-165))*1.32*3.6 = 2.8 m³/h

Which is in fact achievable with his last compressor I think :D

[godmod]

Is there a post missing?
I thought i would have been replying to a very certain post this morning :confused:

[august123]

THx for all the nice words guys :up:



how do you like those Allen Bradley terminals, I work in automation and work with those a lot, as well as Phoenix terminals, I find the Phoenix much nicer to work with.

I took these form an old A/C unit, manufactor is “Weidmüller”. For final electrics I will use Phoenix- Contact terminals.

Impressive work and very nice compressors you've got there! Second stage seem a bit overkill with only -75.5°C evaporating temperature don't you think? Don't you think you could also switch 2nd and 3rd stage compressor to get benefit of the 67ccm for a gas with high specific volume like R14? In every case this beauty may work like a charm :)


It looks like the second compressor is a little bit too big, but we will se how it performs when all four stages are running. I can use frequency modifier here, too :D As you see, I like this machines.



Are you implementing any features to allow control of the temperatures for Cold bugged CPU's ?

Oh and awesome work. Very skilled indeed ;)

As teurorist said, there will be the possibility to change compressor speed, or do some regulation with hot- gas.


Efficience… When you want to have a fast and energy saving PC, buy an new CPU instead of using phase change und overclocked CPU :D


What are fuctions of that XMT7100 controller ? This is controller till -100C :eek: ?



Till -200°C, takes PT100 and K-Type. Little bit cheaper than dixell, only "problem" is that the display is little bit small i think.
Write me PM.

Qv = (P / (h_gaz - h_bub)) * Ug (*3.6 to get m³/h)

For -160°C captube end, -145°C out, 20°C suction temperatue you get
Qv = (315 / (705-165))*1.32*3.6 = 2.8 m³/h

Which is in fact achievable with his last compressor I think :D

Can you give me a tip how long captube for last stage have to be and what diameter it should have? Need to prepare the "extreme" suction line soon, insulation is really heavy :eek: Pics in some weeks.

Is there a post missing?
I thought i would have been replying to a very certain post this morning :confused:

Yes, there was an post with an really huge compressor and some calculation this morning, don`t know what happend :confused: .


stay extreme!

august

[sacha35]

Truly outstanding workmanship and spec august123, this has got to be the best cascade on all accounts for loaded cooling power.

[Clemmaster]

Is there a post missing?
I thought i would have been replying to a very certain post this morning :confused:

Yes I deleted a post with previous calculation because of wrong starting values :) (~30m³/h which was off course a freaky value :rolleyes: )

[Clemmaster]

Can you give me a tip how long captube for last stage have to be and what diameter it should have? Need to prepare the "extreme" suction line soon, insulation is really heavy :eek: Pics in some weeks.


No I can't sorry, I've never played with such gases (very low density :p:) and captube diameter (~1 - 1.2mm seen the length of the line :eek:)

Why don't you try any CPEV to start with and high diameter captube after CPEV? That would be a solution for coldbug :shrug:

[FUGGER]

Moster build, very nice.

CPEV would be a way to adjust temps on the fly, it took quite a few attempts to get the right one. I am using a half ton valves now on my three stage.

I love the cleanness of it all, the power is tight too.

[teurorist]

you joke, the tev in third stage lost at -140 a little bit at gas superheat screw CPEV will be critical, too i think ?and 4m away with only 2mm captube from the cpev to evap you think that will work good ??

i think to find the right captube length this will start with much testing because he also wants to use the 95% methan like ricky

fugger
a -160° cpev who wants touch it to change settings no I think the Adjustment screw will freeze like the screw in the r23 stage at the Expansion Valve
we wanted to change but it was sitting very strange by -80° so what is by -160°C, other problem is the sealing...
but this is my opinion

[godmod]

Since methane is very cheap i would use a captube and try until i got the right lenght. i would not take a cpev because i would be afraid of leak issues.

[DagoDuck]

Good solution.

How are you running this thing? Houses don't come wired for 400v and you'll only see 3phase power in commerical buildings.

[teurorist]

we are in Germany we can have in our houses 63a 3phase 400v
august have 16a 400v 3phase
august learns Electrician ... ;)

[wdrzal]

How are you running this thing? Houses don't come wired for 400v and you'll only see 3phase power in commerical buildings.

You can convert single phase power to 3 phase by making a rotary phase converter out of a 3 phase motor.( You can also boost the power to 460v 3 phase )if needed by use of a transformer. Builing one is simple Depending on HP of load and number of motors run you may also have to add a few capicitors to have a balanced 3 phase load..........

[tim-]

_HL4E_HalfLife_:
in europe almost everyone has 3phase who's living in a detached house.

i got 3phase 400v 63amps for example.. old house had 3phase 400v 25amps..

most people has 3phase comming in the house but it's rare people use 3phase for anything else then sauna and kitchen oven..

[edit]
mr push the wrong botton is here.. 63amps not 64.

not necesary to do that. at least in austria and germany all the 3 phases from the generator come directly to your house. you have 230V from phase to neutral and 400V from one phase to another. so you can have 3 phase power in every building, it just depends if you installed the 3 phases in the house. (sorry, i did not formulate the text good, but its a bit hard for me ;))

WOW...you are crazy man!
i'ts the biggest cascade, and probabily the best i've ever seen before...about the temps, i've no words.... -160° degrees, AMAZING!

Here in Nova Scotia homes have 120/240v 1Phase 60Hz power.

[august123]

hehe i cold never live without 3 phase power :D
Such problems we don`t have in Germany/ Europe. But you in America/ Canada have 60Hz, thats more power with same compressor. Not bad, too.

[Clemmaster]

In france 95% people have only 240~ 1ph in their house even if 3 phases are accessible ;)

AWESOME project august :up:
keep update us :D
btw you can buy danfoss frequency changer (dunno what shold be exact name of it)
but I heard you can overclock copressor to 90Hz :eek:

In france 95% people have only 240~ 1ph in their house even if 3 phases are accessible ;)

OMG
here almost ppl in normal houses has 3 phase

on flats only 220V of course but if someone live in 40-50 old flat he can found 3 phase plug (in kitchen) too lol

[Clemmaster]

In old houses you can find 220~ 3ph for heating, I have it in my holiday's house :D

[Xeon th MG Pony]

you can get 3 phase here in Canada, but the utillity companies really try to not let you as it costs them more to run the line, cheap basterds lol

I`m going to use 8 Meters of 1,1mm Capillary tube for the first test. Will be done in some weeks :cool:

[Bullen]

im speechless!

[mike8913]

you know, as coo as this is, i begin t think to myself: at what point does size and portability outweigh system performance?

[n00b 0f l337]

Hahahahaha a longggg time before this ;)

[august123]

Hahahahaha a longggg time before this ;)

when you take off boxed cooler from your CPU ;)
Honestly, bigger than 2-stage is horrible in size and portability for the advantage it gives you.
Who cares :confused:

Xtreme Cap Tubes :D

[godmod]

Xtreme Cascade? ;)

[wdrzal]

you can get 3 phase here in Canada, but the utillity companies really try to not let you as it costs them more to run the line, cheap basterds lol

All commercial AC electricity is generated in 3 phase. Supplying 3 phase to homes is generally not worth the up front cost that the home owner has to ultimately pay for lines,transformers & equiptment thats has additional circuits.

[TheKarmakazi]

i dont even know what so say.

this is simply amazing work.

so clean and well put together.

one of the nicest cascades ive ever seen, especially for something so HUGE!

congrats man this will be a cpu-killer for sure. theyre all gonna have hypothermia when your done with them!

[august123]

did some work on last stage :

http://www.extremecooling.net/index/e107_files/public/1208626600_119_FT31681_dsc_5229.jpg

(of course the suction line is not final, there will be one with about 4 Meters when unit is running well)

[4Qman]

Wow amazing mate, i wana see numbers hehe

[Duniek]

and I hope you will use a thicker insulation on suction

[august123]

yes of course. Suction line will have about 12cm outer diameter with full insulation.
BTW your evap is great :)

[sacha35]

Any updates august ?

[Moc]

Updates will come in the next two weeks, as far as I am informed.
He organized a benchsession last weekend, there most members of our german phase change forum were, so he had no time to play with this monster :) .

At the moment, I'm doing electronics...

[august123]

i did a litte test this afternoon :)

[teurorist]

and there will come more :D

[toaster]

very nice, august :up:

[teyber]

incredible!

im sure you have plans, but for the size of that cascade i hope you include some sort of bench station ON it. The panels look incredible :O whats the 5th gauge for though?

i am in awe... can't wait to see the casing, seeing how well that panel came out...

regards

[n00b 0f l337]

Incredibly nice, is that R50 in the last stage? Your temperatures across the board look very good for unloaded, except the first which has me a bit uneasy. But.... *huge pat on the back*, congrats :)

[Solarfall]

OMG that thing is HUGE. how much watts does it consume on a full load ??

[teurorist]

stag 1-3 have no problem with the load of the last stag but he didn't made a load test :(

[sacha35]

Outstanding temperatures there mate, totally awesome, what sort of temperatures you are seeing loaded with a quad core in toe.

[DagoDuck]

Congrats! Truly insane. Outstanding work, august! Looking forward to load numbers! :up:

[bazx]

what a great read and build august thanks for sharing

i have enjoyed watching this build

[FireLight]

august you are very very sick man:worship:

Awesome achievement! :)

nice job ;)

Maneurop aren't efficient with high pressure ratio or low suction pressure, that's not that surprising.

Anyway, excellent (not to say perfect :shrug:) job you made there august :up:, now you have another thing to care of : coldbug :p:

[Duniek]

forget :D
this cascade is for cedar mills :ROTF:

[august123]

first stage temperature is already a little bit to low, i use R23 as refrigerant in second stage, it`s easy to condence. With -40 in first stage, my pressure in second stage is a way to low. But it works.

[PhilippF]

I dont know exactly, but the actual idle temps on this cascade should be world record (at least among the overclocker cascades)?

Ooops, didnt you post them yet?

[DagoDuck]

Not yet. :p:

[august123]

but I can give you icewater pics & correct evaporating temperature ;) I don`t want to discuss that here...

[teurorist]

i cant wait i will bench on it :D

[Duniek]

now Germans will be famous on three things in my guess
- Porsche cars
- Oktoberfest
- august123 quad cascade

:D :p:

Nice job, we wait for suite with impatience

Insane build my friend! Now you got to find a cpu that can this cold.

[jcool]

Holy :banana::banana::banana::banana:ing :banana::banana::banana::banana: this is incredible. Truly amazing work there August. :clap::clap::clap:

Where do you guys meet for benching anyway? Next time I might join the club just to see this monster is real :shocked: :up:

That is just incredible :eek:
Fine work there my friend, truly awesome :clap:

who the hell needs LN2 :ROTF:

[teurorist]

it's not the final ;) but he will do some Reconstruction Town (i think you cal it so)
and he have to build 2 Cascades 1 goes to No_name
but he get a n1 sps and a minicomputer for sps (i don't now in English sps its a siemens controller ;) )

AMAZING WORK :D

The coldest I have ever seen!

[august123]

and it still needs capillary tuning in last stage :D

http://www.extremecooling.net/index/e107_files/public/1214848630_119_FT31681_dsc_3813.jpg

Can't wait to work on it, but there is so much other work :( As always.

[n00b 0f l337]

Really is one hell of an electronics system.

[HitandRun]

Really the Germans! Gute arbeit! Alles Siemens auch was sonst! :up:

[august123]

Siemens und Moeller, und noch Danfoss Technik :D German High- Tech.

[HitandRun]

Siemens und Moeller, und noch Danfoss Technik :D German High- Tech.

Kenne ich alles! Good choice and it will work excellent! Work with all this stuff a lot! Danfoss freq. drives are the shizzznet! :up:

[just a noob]

how much is the electricity bill going to be for 1 hours of use, and how much does it weigh, sorry if these have been asked already

[august123]

about 1 Euro per hour (thats cheap :D), no idea of weight at the moment but she shold be between 120 and 200kg.

[one_servant]

Well done! I'm astounded at your engineering skill. Beautiful fit and finish and amazing results! Thanks for sharing all the photographs with us. :clap:

[teurorist]

i have to say it's like a family project august is planing all and when his brother have time he is helping a bit also his Father. Last Monday, when we put it down his mother and sister are helping too.
and the dog is looking that no Burglar go to the quad stage :D (he was at Monday not good with me ;) )

Germany Rocks
HitandRun you are relay cool :D

[wdrzal]

Looks like some of XS's builder's are really throwing down the gauntlet and moving builds to a very high professional level. :up::up::up:

[FireLight]

like i say you are very sick man august:up:

[Duh]

you are even making it aesthetically beautiful ( i really like the metal panels). take the time you need, dont allow us to pressure you.

I am having german lessons at the university : habe sie gut geschlafen august? I habe nicht gut geschlafen :S

[godmod]

"Ich habe auch nicht gut geschlafen, da ich jeden Tag um 6 Uhr früh aufstehen muss um zur Arbeit zu fahren :("

now you :p

august123, as it already had been said multiple times: wonderful project, awesome work with attention to detail! I hope you find time to continue soon.

holy mashed potato's! very nice really industrial look there!

[* icy *]

Sehr gut August. Deutschland über alles :up: Like others, I really like front metal panel too and stuff inside also. Whole project is awesome :worship:

Godmod, du bist nicht allein, ich auch :yepp: Wo arbeitest du, welche Stadt?

[august123]

i really like all that positive feedback! That makes me happy :D

Need to build in my other nice electronik things, and of course, finish 4rd stage soon.

stay cool,
August123

PS. Hier gibt es ja einige die perfekt Deutsch sprechen :)

[captaincascade]

You guys are out of control!! Hows anybody gunna top this? What now we gotta get multihorsepower compound compressors to compete lol. Great job on this one. i would like to hear your pressures if possible, never played with methane. very impressive.



Oh and hey guys long time no see, great to be back and all.

Ich spreche Spanish (our teacher told us to pronounce it shpansih) und English , un Sier herr august? :)

As I ve told you before I really admire your unit and the technology you ve used as well as I love Deutsche ( although I am just starting to understand very little ) :)
