very nice work bazx :)
thanks my friend good to see you in here:DQuote:

atm blue the same colour as the chassis
i have also noticed the unit is starting to look like wall-e

Looks like Monster :)) .
Can You post final temperatures ?
What are dimension of it :) ?
Panels - maybe white ?:rolleyes:
regards
whats the final weight on this beast
@peter i am experimenting with using a tev for the r14 mounted on the back of the evap so the unit is not quite there as far as temps are concerned atm the 3rd stage has 1150 in
@Ozzfest05 i don't know but i cannot lift it
nice one bazx i can just imagine it now , you going to a lan party and saying do you mind if i use my own cooling unit then you come into the room pushing the beast and it goes silent and all you hear is thye wheels creaking as you roll it along , nice quality of build, what was the overalll cost of building excluding the 100s of hours work you put in
i don't honestly know the cost of this unit in parts but more then 2kQuote:

One word, "WOW" whats the weight on that SOB? I hope you dont have to ship it to the next event!
Damn impressive man. I really hope you can work out the R14 issues. How did NoL make it work yet the two of you are having such huge issues? Would be great to see that baby pull down to -140C :up:
Very impressive. How loud is it?
getting a temp of -139 is one thing having a unit that does it every time you turn your unit on and can bench with a load on it is where both me and sacha35Quote:

@annton How loud is it? it was very loud before the panels went on however i have yet to try it with them on
hey whats the weight on it baz? can you lift it? are you using cap tube or a txv on the third stage? how much do you think it cost? how loud is it?
:p: :p:
hehe im just playing with you. i hope the txv fixes those frustrating r14 issues
Spectacular build. Congrats :up:
Indeed a spectacular build! :up: Is it possible you have oil related issues? Would two oil separator in series solve this issue? Have you ever tried CPEV evaporator feeding on third stage?
i had originally thought it was oil but not any more it works fine with 1150 which off load can get to -115 if there were oil there i would see problems with both refrigerantsQuote:

I still think alot of your problems are oil related Bazx.
Hope you get it pulling major ass kicking soon though it seems like it does that more then enough already :)
Cpev
after quite a bit of work with R14 i am beginning to understand its behavior a little better
link to earlier work with a tev and r14
http://www.xtremesystems.org/FORUMS/...d.php?t=214659
i have moved to a cpev (supplied by piotres) setup for the first time and so far i like it
it does not seem to leak at very cold temps altho atm i have not tried one under load
but it installed very easy and pulled down to -132
hp is 8 bar atm but most likely rise to 9 bar under load
vacuum is - 5 but i expect it to settle around 0 also once under load
the evap is a chilly clone but 1/3 longer supplied by cold ice and has 3x 2mm cross holes leading to the suction return near the base
the feed from the cpev is 1/4 and feeds in at the top of the spiral
if you look down the evap you can see the cross drilled return holes

i will be load testing on Saturday with the same AMD rig i used in the tev experiments:)

8 bar hp

temp probs fixed at evap wall on the dt and suction return on the fluke
If you do have oil issues it will log up in the cpev after running a bit and temps will drop. Very nice experiment bazx - we're all watching:D
ron if this fails mate i am going back to R1150:D
R14 has been a long and costly journey and i need to be nearing the end
also i have found that most oil problems with the refrigerant are at least with my experience linked to high vacuum
if you can control the vacuum and keep it the right side of -10 it tends not to pull oil thro the oil separator
paul came over sunday and we spent the day tunning the unit to work with R14 and the cpev under load
we completed the work with the cpev
and i have my unit stable under load now @-122 which is at around 230w (i used a cpu@1.8v5000mhz with wprime on all for cores and measured the load)
first stage refrigerant has been changed to 404a (this is just a cost saver as i did not need to go to the expense of 507)
i used a 02 orifice on the first stage and a 00 on the second stage which is the r23 tev but this is very close to its maximum and i think i will change this to a 01 orifice soon
the r14 stage needed 11.5 bar hp to hold load which i thought was a little high i had expected it to work @ 9 bar with the r23 stage @ -82 but my gauges might be out a little
one thing i have found with this refrigerant is it wont work in a strong vacuum any more then -10 inch and it wont pull down
under load i have vacuum @ +1 and high pressure at 11.5 bar this give me -122c
ready for some benching now:D
AMD are sending over a 955 CPU and Gigabyte have supplied a MA790XT-UD4P which is an AM3 setup so that will be my next project

Bazx congrats!!
I bet this feels awesome !!!
man you have no idea how many times i have almost given up on this refrigerantQuote:

Holy smoke, bazx. This is a real accomplishment!
Hats off to you, sir! :up:
Thats awesome I want a Phenom II so bad right now but the wife is already having fits about my tool purchases :)Quote:

Nice numbers :clap:.
Can You compare how many *C You gain after swap from modded tev to cpev (idle/load) ?
Does CPEV used with R14 needs frequent tuning ?
Regards
Peter
i must say peter the cpev solution to my R14 problems is by far the bestQuote:

Great job bazx!!;) You are an inspiration. :clap:
I'm guessing you used tes2 with 02 orifice on first stage and a tes2 with 00 (future change to 01) orifice on second with a cpev on third.
Was second stage a tes2? I know you said tev for r23, which a tes2 isn't.
hi ron
tevs used
TES 2 danfoss (02 orifice) R404,TEB2 danfoss (01 orifice) R23 (from Cold_ice), cpev R14(from piotres)
data on TEB 2
http://hr.refrignet.danfoss.com/RA/P...selectedTab=IN
cold_ice shop
http://www.kaeltetechnik-shop.at/Exp...-55C-Danfoss_1
i put the 01 in the TEB2 last night so will be vacuuming down today and testing
will let ya know how that went
Any news on 01 orifice results for the TEB2?:)Quote:

yes i think i would ron
with the 02 orifice whist i have lost some temps with this one it has given me an us-shakeable 1st stage @ -37
the 01 is in the 2nd stage now which has lead to a rise in temp also -73 but again this is now very stable
the knock on effect of this has been an increase in high pressure in the 3rd stage to 15 bar @ full load with a temp of -125
the unit is now full stable at this temp @ around 250w
i would add that if i looked back i can see some things i would change
1. i would go for cpev on all stages tevs are good but have restricted my refrigerant choices
2.refrigerants: i would use/tryed the following instead of the one i have used
R402 or R507/R170/R14
imo opinion the above would have given me some slack on each stage
and would more then lightly held load on each stage @ lower temp
