Next steps:

Drain compressor oil

Layout where compressor and condenser are going and mount them.

Cut base wood platform down to size

Start pipe bending to get ready for Brazing

Go on vacation from 2/13 until 2/19 :)

Braze evap

and, and, and :-)

Absolutely loving that attitude m8 :clap: :up:

Looks like its gonne be one cool build. I wish my SS was stronger, I am limited by cooling with my 920 at 4,4 right now :ROTF: :rolleyes:

[sdumper]

Going with .042 cap...

A few more picts...bolted down the condenser/compressor
Cut my accumulator and added a flow reduction coil inside and drilled end caps

Hmmm. .042 cap tube @ 92 5/8 inches? I wonder if I should follow your lead with that for my build.... That isn't just specific for danfoss compressor's, right? Also, what's the accumulator for? Should I have one of those too?

hey my friend you should get a refrigeration book and read through it :up:

cap tube is different for every different refrigerant/compressor. the accumulator traps liquid in the low side so you don't get compressor slugging/floodback (er, well helps with it :rolleyes:)

Well, we are using the same gas and have about the same load. The Danfoss app doesn't let you specify which compressor, sooooooo, why would they make a recommendation of cap tube size/length without a model number?

The program makes a recommendation on massflow, you then match the compressor to that. I haven't used DanCap much but it seems in most cases to offer a close estimate to what I would originally guess. As always though, nothing replaces book knowledge coupled with years of experience, both of which I'm a bit short on :(

How does it make a recommendation based on massflow if it doesnt know the compression ratio and displacement of the compressor? Maybe it makes a generalization on those based on the refrigerant used? (ex: 134a most danfoss compressors are 7cm^3?)

LoL thats what I keep telling my wife but she wont budge :)

Used a pipe bender this time and the desuper looks a bit better than my last build...

http://i190.photobucket.com/albums/z294/sdumper/IMG00281.jpg

[MeltedDuron]

Personly i would of gone for a large ring style. Wrapping the copper around a tank per say, perhpas a MAP or Propane type or larger too fit directly in the path of the condenser. Then bend the rest to fit with the tube bender. More anit vibe and more cooling on the DSHC

[sdumper]

Dont think I need it directly in front of the fan because my condenser is huge. Maybe I should lower it hmmm....

I also intend to run my suction at the base in front of the fan at the bottom so I wanted my desuper as far away from the insulation as possible.
As for the vibe im thinking that if its a problem I can spread the coils out a bit but the tight coil approach seems to work well on the Mach II GT design.

[teyber]

no don't, this is so far looking much better then the last one mate :)

if you stick to all the same components every time it will make making these quite easy : )

this looks very nice mate

You list the heat needed to be removed at the temperature specified. It then figures out with the refrigerant selected how much mass you need to remove that amount of heat. It is then your job to size the compressor appropriately for the amount of mass-flow you need through the system.

[sdumper]

Going to make this more compact and have airflow from side to side so that it can take on more of a long rectangle shape.

The size of the condenser makes it impossible to have it front to back without making the case huge.
The shroud is just a mock to show how far out the fan will stick ...
The accumulator and electrical will go in the back..

[godmod]

are you planning to only use one fan? (don't think so..)

The components are nice, but to the desuperheater coil: with a well dimensioned condenser you dont need a desuperheater, just a few turns for vibration dampening; so you could have done one or two turn with a larger diameter and saved copper.

[sdumper]

Nope using two in the front 1 in back :)

Just propped it up to show spacing.

Regarding desuper..Goemler was telling me the same thing but its a PITA to shorten it now because of all the bends...

[sdumper]

Ok back from vacation and brazed the accumulator and evap last night. I should have Ice by this weekend.

Question on Accumulator angle.
If I angle my accumulator at 90 degrees so that the end feeding into the compressor is highest will this cause any issues? I am very cramped for space and that would simplify things for me but I havent seen anyone else doing that so wasn't sure.

long dsh isn't necessary but is cheap and looks nice :) if you were in mass production with the large condenser it isn't needed but hey... i think it makes it look "more advanced" :p:

[sdumper]

Teyber any thoughts on the angle of the accumulator?

Teyber any thoughts on the angle of the accumulator?

Depends on how it is designed. ill snag some pics later today of a combination slhx/ accumulator i made the other day(2) that is verticle

[sdumper]

Quick question...the last time I used my Oxy/Acet torch on a filter drier/captube I burned right through my filter drier.

I have been brazing with my Oxy/Acet a lot lately and think I have the main techniques down but I am getting ready to braze a cap into my filter drier again...so any tips on the flame length and color?

[sdumper]

Figured it out and am now pressure testing at 250psi

[wdrzal]

The inner blue part of the flame(close to the tip) should just start to feather(not a single point)multiple small points 3 or 4 usually.,a real quit& relitivly cool flame (for a 2 gas torch),not a lot of Blow.. a couple psi actylene < 3 to 5 depending on tip size. 10 psi o2 is usually enough.

[sdumper]

Thanks Walt!!

BTW I really like using oxy/acet over mapp now that I have had a chance to play with it some. The brazing time is more than cut in 1/2 because I can heat the metal up to red hot very quick.

[sdumper]

Really embarrassing question but I have a digital vacuum gauge and have absolutely no idea how to use it can someone give me a quick tutorial?

[teyber]

Hey!

No worries at all. Your system looks great :) :up: can't wait to see how the evap performs.

your vacuum gauge is very finicky so don't use it until you have the ropes, they can die easily if you do someothing wrong. Lets chat on msn or you can call me maybe i could help you out as we have the same gauge i think (vg64)

cheers :up:

[sdumper]

yep same gauge :)
Im on msn now if your around

[sdumper]

Hey im a bit perplexed by the vg64 specifications.
http://www.microdaq.com/supco/digital_vacuum_gauge.php

Do you know what they mean by this? Do they mean that when the supco displays between 1001 to 2000 microns its really 50 microns???

0 to 200: 1 Micron
201 to 500: 5 Microns
501-1,000: 10 Microns
1,001 to 2,000: 50 Microns
2,001 to 5,000: 250 Microns
5,001 to 8,000: 500 Microns
8,001 to 12,000: 1,000 Microns


-edit- LOL I have been a bit nervous because after vacuuming for 12 hours my vg64 was reading only 1000 microns...
So I went to googling and that was the reason for the post above. Anyway I checked my manifold and realized I didnt have my valves opened all the way and as soon as I opened the valves I started dropping microns dramatically...

Lesson learned...and im sure I will learn many more along the way :)

[godmod]

1,001 to 2,000: 50 Microns
2,001 to 5,000: 250 Microns
5,001 to 8,000: 500 Microns
8,001 to 12,000: 1,000 Microns


That should be the resolution in those ranges

[sdumper]

Thanks GodMod that makes sense :)

[sdumper]

When pulling a vacuum I had the low side connected but not the high side because I used the high side hose to connect to my digital vacuum gauge.
Will this interfere with pulling a good vacuum?

Well I got ICE but have a ton of tuning to do obviously...

Very low charge.....

http://i190.photobucket.com/albums/z294/sdumper/IMG00300.jpg



Loaded high 180psi low 2psi and holding 270 watts at -34c and is starting to flash between -34c and -35c so temps are dropping a bit still also temp probe very low on the evap...

More tuning and picts after insulation

Whats really surprising to me is that by making the accumulator 8.5 inches, wrapping cap tube inside and funneling in with a dowsize to 1/4 pipe and out with 1/4 pipe I am getting none of that irritating pinging sound that comes with floodback at idle loads.

Trying to mimick idle on an i7 so set for 70 watts
http://i190.photobucket.com/albums/z294/sdumper/IMG00308.jpg

Bumped it up to 90 watts and still a decent temp i suppose...
http://i190.photobucket.com/albums/z294/sdumper/IMG00309.jpg

[filmbot]

I'm no phase expert but for a first build and only a SS, very good temps so far!

Get to tuning and insulating everything and give us some 250w temps :up:

[sdumper]

Not my first build....but thanks :)

BTW: its already loaded at 270 watts and holding -34c/-35c and this is a build for ThaWaxShop not me :)

[[XC] gomeler]

Very nicely done, good to see the accumulator with the coiled capillary is working well.

[sdumper]

Thanks Chris Im amazed by the accumulator and the difference it made. Also .042 cap at 10 feet worked better than I hoped.

nice! glad to see the evap handling that kind of load :) those are some unreal load temps

[SexyMF]

If you are selling this unit then you must follow correct wiring and protection.

[teyber]

of course he will neaten and safen it up mate, im sure this is just for testing :)

[V2-V3]

Nice SS phase unit!

What are you using for a load tester?

[sdumper]

This is not even the starting components that im using :) I borrowed it from a similar build I am using for proof of concept.
The completed unit will have a streamlined case, fan shroud, wiring harness. I just didn't have all the parts in yet so I had to use what I had for tuning/testing purposes.




Nice SS phase unit!

Thanks and heres a link to my Q&A thread on wiring the dual 150 watt cartriges and block which I bought from DetroitAC.

[teyber]

hey i can't tell if you coiled cap tube in the hx to add restrition or you coiled "the" cap tube for a slhx effect?

cheers

[sdumper]

Coiled a 5 inch piece of cap tube in the center of the Accum, used 1/4 pipe for stubs on entry and exit of accum to further restrict the flow and last made the accum really long 8.5 inches. Results no flood back and handles load perfectly even at 300 watts which im verifying right now (so far 45 minutes at -32c on evap and -4c near top of heatloader. Temp touching the cartridge itself is 1c...

I just hope the i7 isn't pulling more than 300 watts

[Gunslinger]

lol, send it to me and we'll find out. :ROTF:

[sdumper]

Your not far away just drive down with your i7 and will test it :)

[[XC] gomeler]

That would be fun, I'd drag my happy arse out there to test my cascade on a Core i7 965 :p:

[Gunslinger]

Sounds like a plan is needed......Will have to check calendar, as I have another nephew due any day now in Nashville.

[sdumper]

Sounds good!!

Maybe we could do a ethelyn charge on the 3 stager and see how it works without r14....

Chris whats yellowbeard up to these days because I think he has a couple of es I7 chip he was using while he tested his DDR3 kits.

[[XC] gomeler]

The 3 stager with R1150 would pull around -110C loaded with a deep vacuum. Just a guess, could be fun.

Yellowbeard has been busy pulling double duty with Corsair, been too busy to bench. He has a 965 he uses for testing, doubt he'd want to blast volts through it though. Maybe when the D0 revision launches I'll pick one up :shrug:

[TheKarmakazi]

Seems this unit is destined to find its way to my benchroom :D

Thanks SD :up:

Final picts of the build with all electrical done.
I will need to even out the base with a jigsaw when I crate this for shipment this afternoon.

Also note my date is set wrong on my wifes camera I just took this 5 minutes ago :)

2) What is your electrical setup? It is not clear from the pics.

That sounds pretty much like my system.

It holds the 965XE and a 4.6GHz OC just fine, about -36c idle and never gone below -29c on max load of 3DMark06 CPU Test #1

Yep its a beast when I compare it to my Mach II its not even in the same league. My modded Mach II gt crashes when I try 300 watts on the heat loader so im very pleased with how well this holds temps.
