Naked, 2x 1HP cascade

Hello

I move this cascade from this topic : http://www.xtremesystems.org/forums/...=166418&page=3, becasue this contest finished :) .

This is quite ordinary cascade - metal baseplate, plate HX, R507/R1150, 4 gauges ...but it finally have 2x 12000 BTU,1HP compressors, not ordinary for me 9000-11000 BTU :D .

Specs :

compressors: Sanyo remark C-RN110H5A around 12000 BTU so 1HP on both stages
evap: steeper
XVes: ALCO TI-HW (designed for R22, but I bet it'll be working well with R507) + nozzle 01 / captube 0.9 mm
HX: plate HX , 12 plates
condenser: 3.0 Kw, alu-cu, cooled by 300mm/230V fan
refrigerants : R507/R1150
oilseparator : Shine Year automatic
safety : JOHNSON CONTROLS cut-off, 1.8 litre TORRECILLA expansion tank
case : baseplate 46 x 46 cm, zincked steel + wheels
others: 4*REFCO gauges, Anaconda shocks absorber on 1st stage's suction line,DIXELL XR20CX controller (turn on 2nd stage automatically when 1st stage is enought cold) .

TORRECILLA 1.8L receiver will be modded to expansion tank :D .

Then ...

I've decided to use 12000 BTU 1HP compressor in both stages :D :

and more work ...

http://www.members.lycos.co.uk/piotres2/solar/19.jpg

Finally, I've put wooden plate under steel plate to make it more stiff - those 1HP rotaries aren't light ;-) .

Temperatures during filling,no loaded, with almost no insulation :) (except that which You can see so on suction line and on HX) .

I've already almost made complete insulation, in next few days I'll made electrics and final tests on new 260W dummyload which is already waiting for frost :D .

this one is for me right :)

hehe, sorry but no :p: .

Nice work like always Piotres ?

Are people queing up ?

In pic #11, it looks like you've polished the evap base to a distorted shape???

I've been worried about doing that, so I've not yet made one a mirror finish.

Looks a little distorted to me also. You can avoid that by sanding on glass as you all know. But instead of polishing with a wheel or by hand you can use what is called Finnese sanding paper. With soapy water you can SAND to a mirror finish.
Edit: Sorry, forgot to say that sand paper goes to 12,000 grit.

Mirror need to be quite thick to be honest. Machinisit Granite FTW on that one if someone is patient.

I think that it is just the way the picture is taken.

Did you make the base yourself?

Pretty sure that's not flat.
Attachment 70005

Maybe Convexed? :) After all that is the rage with waterblock it seems.

Ha, I didn't even notice that.

this is why i don't polish evaps ;) justd grind it with 1200-2000grint and you're fine I've done even more but it doesn't affect the performance.

Yes, maybe 2mm ring on the outer side of evap isn't flat, but rest is rather flat :) .

Ok, You're right in hand it's hard to polish and sand evap to make it absolutelly flat, so do You think I shouldn't polish evap in future anymore ? :rolleyes:

Thanks,
Peter

Well, to be quite honest, YES I think we all should not polish evap bases anymore (well, I'm already on that wagon, it's too much work :rolleyes: ). A polished base seems more about bling to me than reality. Reality is you need a very FLAT surface first, provided the IHS is flat, and your evap doesn't flex when clamped to the cpu ( I think the flex is quite small compared to thin/wide waterblocks). If you can lap it to a better suface finish, that's great (it takes some good technique) but you shouldn't sacrifice flatness in the process. A very nice looking fun-house mirror evap base is not going to make good thermal contact. How about polish the rest of the evap for bling factor. (your evaps and piping are quite beautiful Piotres :clap: )

In regard to that. I wonder how can controlled convex lapping can be done... IHS unfortunately tend to be bowed in (concaved) now a day -_-; And you know how well thermal paste transfers heat at that temp... bleh...

excellent seems like my cascade is almost finished.. :toast:
i was gonna ask for more pics today but seems like you beat me to it :D..
im eagerly waiting for the final tests !!!

Seems like someone got what they wanted for Christmas ;) I am jealous! :p:

Piotres...if you can please can you make a video of the cascade running? Iv never heard rotaries in action before... :D

Thankyou and....the unit looks impressive :D

K

Its hard to gauge how loud something is from a video without a reference. It would be better to get a db meter and give a spec. But I love youtube videos! :D

Hehe, please don't stop with polish'ing evaps. The evap on the cascade you made me was pretty flat imo.

Don't forget there's more than just cpu's :rolleyes:

I can make a video for you. I'm also a happy owner of a piotres rotary cascade.

"The sound" is not roommate friendly...To give you a little indication.

Please make that video Magoa ...and put it on Youtube with "piotres" in title please so search engine can find it :) .

You can find already on Youtube one of mine cascades (ultramarine one) :D -just put piotres in search window :) .

Today I check contact with dummyload - pretty good I can say, paste was thin after unmount. I'll upload pics of that too . :)

Thanks
Peter

Nice cascade as always! Hope that you can do the load-tests soon :)

About the polished evaps - the one you made for me is also flat in the middle and looks on the outside like the one for this cascade.
You can see this only on the thermal paste when the evap was mounted on a dummyload. A normal S.775 CPU is a bit smaller, so the outside of the evap is not really important...

Evap after unmounting it from 225W dummyload, that part non covered with paste wasn't covered in mounting process :( .

Insulation and electric done, so now only final tests left :) .

I plan to make them in first half of this week :) .

Best Regards
Peter

looks good as always :) keep up the good work dude :up:

good work mate.. looks just the way i pictured it.. i'm loving it.
good thing you convinced me to select the green suction line sleeve as the color.. its freaking hawt :toast:
now hurry up with those final tests peter i wanna see what that baby can do :D

just out of curiosity. how heavy is that thing ???

Hello

Cascade is finally tunned and tomorrow will be 100% finished (today 99.5 % :D ) , I'll upload pics tomorrow too :) .

Results :

-107*C unloaded

-100*C @ 225W dummyload

-98*C @ 260W dummyload

Cascade is tunned to hold load over 300W . If I want to tune it for 260W as a max , it can done -101*C@260W :) .

The cascade is approx 55-70 kg .

Best Regards
Peter

wow very nice piotres !

Wow... impressive temps at such a huge load.

Why not tune for a lower load with the new 45nm chips? Is the customer using Kentsfield 65nm?

who knows how the next chip might be...better tune it for higher loads :)

nice number's.. pretty much what i expected :D

fantastic Piotres! :up:

Thanks guys :D !

Yesterday I back too late, and was too dark in that room where cascade is standing to make good pictures :( .

Today at morining I'll show pics of finished cascade :) .

Best Regards
Peter

So as I've said :D ... :

http://www.members.lycos.co.uk/piotres2/solar/39.jpg

Some final changes, mainly in electric ;) .

http://www.members.lycos.co.uk/piotres2/solar/40.jpg

First time when I powered it on in house :) .

http://www.members.lycos.co.uk/piotres2/solar/41.jpg

On 260W dummyload .

It can be tunned to make -101*C@260W , but that time 260W will be max load which it can hold .

http://www.members.lycos.co.uk/piotres2/solar/42.jpg

On 225W dummyload.

http://www.members.lycos.co.uk/piotres2/solar/43.jpg

First stage , when 2nd stage was loaded with 225W.

http://www.members.lycos.co.uk/piotres2/solar/48.jpg

http://www.members.lycos.co.uk/piotres2/solar/49.jpg

Together with some insulations :D .

Unloaded is finally around -107*C . :)

Best Regards
Peter

Nice pictures and a really powerful cascade :up:

Only the pressure gauges could be installed in a row, then it would look a bit cleaner..

The ND gauges show a pretty high pressure, is your static pressure on both stages about 9 -10 bar?

look about that, godmod.

All so should be said having the low side guages over pressurized like that is going to throw out their calibration! For futur builds you may want to use a higher pressur rated gauge for the Low side so it can handle the off cycle pressur better.

I've never seen any gauges with scale over 10 bara on low side. :(

But that's right, should be higher scale, I'll look to REFCO catalog later .

Best Regards
Peter

piotres;
buy r410 scales :) they are normally ~16bar lowside.

damn piotres she is a beauty..can wait to try it out :D

Ya I was thinking R-410 Low side gauges would be ideal as well.

Hello

Cascade has been sent some days ago, I hope it's well packed :D :

http://www.members.lycos.co.uk/piotres2/solar/50.jpg

Wooden plates are 19 mm thick :) .

Thanks
Peter

Peter, very nice cascade and I really like how you did your new load tester :) Good insulation all around and definitely plus for having consistant read out and tuning :)

Nice job indeed!

Nice job... very compact and powerful. :up:

YEESSS cant wait to get my hands on it..some cpus are gonna get punnished SOOoon :D
nice jop piotres.. ur da man :up:

Very nice job Piotres, I was always impressed by your clean and good work !

I dont know Solarfall, I dont think you be able to handle it;) better off sending it to me:D

Remember Solarfall, this isnt the BLACK MAMBA, this is for your computer:rofl:


Beautiful work piotres :clap:

i like the packing job :up:

Wow, as always very nice.

alrighty got the cascade today...works perfectly..:D:D:D:D:D:D:D
i must say you did awesome job packing the unit piotres it took a while to open the damn crate :D

here she is :D

Now thats a pretty one :D

What to do if you have coldbug at lets say -90 ?

you can use a coppershim ;)

btw nice unit piotres :up:

did some clocking with the cascade today...IT'S AWESOME.. i took a small vid for you guys.. :D

What would be correct? The bios reading -127 or the unit reading -46? Sounds evil hehehe

-46 is first stage temp, the probe on the evap isnt connected.

-127 isn't true. software temperatures is not close to real temp, more correct would be somewhere in the -90*c range.

I've seen bios show from +190*c to -70isch on SS in bios.. due to the bad temp reading, especially in negative temps.

Nice video Solar :) .

Well I just want to say that I do mine job ...job which I enjoy :D .

I wish You awesome OC scores now :clap: .

Best Regards,
Piotres

LOL guys of course thats not the real temp just though it was kinda funny.. obviously the dfi bios is showing the temp readings all wrong.. im guessing that the real temps would be around -100c.. dont really know for sure though since my trusty temp meter is broken.. :(

so how is tha cascade going???

interested to use an tx2(r22 designed valve) with freon r404a, thats y i'm asking!

thx

TXV which I use there, work with R507 as good as danfoss TS2 TXV designed for 404a/507 :)

I had a mobo (p5b-d?) that would show 255c if it went below -9.
