My DD Unit

[sl4ck]

Some time doing this, searching for material, no time to work on this, but keep going

Need some advice about the capilar lenght, i'll be using 0.8 (.031) with R440a

Embraco 1/3hp
30gr filter/dryer

And this condensor:
22cm = 8.66"

[Bergo]

looking very nice, is that your own Evap enclosure or one from a mach1 or something?

[sl4ck]

it's from vapochill LS

[sl4ck]

no one has capilary lenght advice? :slap:

[quintus]

patience! and look around: http://www.xtremesystems.org/forums/showthread.php?t=29694
u must know also the heatload for what u gonna use this toy...
gr, q

[sl4ck]

i'm estimating 200W = 3,08m capilary

[Marvin]

thats a very nice system. Congratulations.

[Ssilencer]

I built my last unit with almost the same compressor and r502, I used 3.20mts of 0.031, I think 3mts will be ok.

[sl4ck]

Thx Ssilencer ;)

[sl4ck]

Update here :)

The minimum temp. i can show you is -49.7 :(, my "uGuru" :lol: only reads -50, and i don´t have another thermometer

Vacuum with an old compressor i have here, but i'm glad with this temp, i'm gonna try to get a good thermometer and vacuum pump.

It misses the LCD, side panel and rest of the insulation

Hey nice case, what is that hole on the front for...?

Let me guess... you want the answer to be... that hole is for my G-froster XE, the most beautifullest bestest thing ever :woot: :banana: :woot: :slapass:

[Ssilencer]

I'd buy a GFroster in an instant if I had the money. I'll probably have to take it to PM's, but ssilencer, would you be willing to ship an unassembled gfroster for a bit cheaper than an assembled one? Like, just the parts + pcb.

Man, you had a really nice gesture with us sometime ago, and I dont forget that, send me a pm, we will find a way.

[sl4ck]

i'd like to get one gfroster but it gets a little bit expensive for the money i have now :(

[Ssilencer]

I will be sending 4 G-Forster Xe to portugal next week.
It depends on what froster you want to get.

[Blaster]

im waiting for them :D

[4everCS]

I want that case!!! Your system looks great!

[MaRtIe]

how long did it take to get you down to 0Hg with using a compressor as vac?

[sl4ck]

only a few seconds.

I run Vacuum for 30 minutes, charge the system with 50PSI, hold for 5 minutes, run Vacumm again for 30 minutes and charge again with 50 PSI, hold for 5 minutes and let it run vacuum for 15 Hours(night and morning).

[sl4ck]

What do you think about this:

160PSIg seems a little low compared to what I've seen others use. Most that I've seen are closer to 200PSIg.

I think you are not getting enough mass flow due to this lower pressure, hence the unit can't hold the load of your CPU at a lower temp. Don't hold me to this though.

[sl4ck]

maybe capilar tube to big? I have 10feet (3m) of 0.031"(0.8mm) cap tube, maybe better try with less 4" (10cm) cap tube !?

I agree.

U need more gas in it to hold load

[PT mode on]
Mas esta fixe !! :D
[/PT mode off]

[sl4ck]

Blaster but less than 200 PSI (180~190) i have entire succion frozen until compressor and that cannot hapen

[yngndrw]

Then your cap tube is too short.

You tuned your cap tube for 200Watts, but I bet your CPU is giving out nowhere near 200Watts.

[sl4ck]

how much Watts a 3700+ SD @ 3000Mhz @ 1,6vcore dissipates?

[Ssilencer]

You can have you suction frozen, what you dont have to get is liquid return in the compressor.
I agre with blaster, put a little more gas on it, almost 200psi on load is ok for r404.

"Then your cap tube is too short.

You tuned your cap tube for 200Watts, but I bet your CPU is giving out nowhere near 200Watts."

If the cap tube is too short, he is having a lot more capacity, then there's no way the unit cannot hold good temps on less watts.

I want to know how are your evap temps, idle and load.

[sl4ck]

i was thinking ice should be from 2~3cm from compressor on succion :confused:

200PSI temps got worst :( -3 Full Load

[Blaster]

ice formation on suction depends on system config


can you show us the evaporator temps like Mr. S asked ? :D

[sl4ck]

-36 Idle
-34 Full

[Ssilencer]

Mr S... LOL
Mmm I dont like your evap temps at all, something is wrong, you can't have 1 or 2hg and -34c with r404

[Blaster]

wheres the sensor of the evap thermometer?

[jinu117]

-36 Idle
-34 Full

Ahaha.... haha... yes... you did tune it for way too much load. (even if it is sitting right at suction line start for probe where it is coldest). The specification you mentioned on my test only netted like 115W or so... :P Try tuning for about 150W and that is good for quite some time for cpu. Great temp though... I think evap temp is still better than vapo LS :) considering load tuned for.

[sl4ck]

My evap sensor is something like this:

http://img157.imageshack.us/img157/2151/sensor8sq.jpg


So, i have to size my cap tube to 15.7 Feet(4.8m) of 0.031 (0.8mm)?

By the 0.031 (0,8mm) cap tube Gary Lloyd rule 150W = 10feet(3m) x 1.6 = 15.7 Feet(4.8m)

m I correct? :D

[LittleDevil]

What about for R402a gas, how long captube (0,7mm) do you recomended?

tnx

I dont think so
I really dont understand, 3mts of 0.031 and -36 idle is not good at all, I built a unit with same compresor and same cap tube and same gas, got more than 10 degrees better temps, anyway, I hate r404, later regased with r502 and it was a happy unit ever after :D.
Again, pressures do not correspond with temps, even if we get a little delta ( 5/6 degrees) from the temp probe and gas pressure.

So Jinu, what's your help?, "your specs, your tests" but not a tiny little number to tell the guy to try... I know that lately we are in the secret service (secret gas mixes, secret way to hold a load with no gas, secret indications of good evaps just comparing with nothing, etc) but I think he need help, you were doing a lot of testing last months with cap tubes, give him a clue.:)

Littledevil, I dont use r402, so I can't recomend anything on that, being a lot of people with real experience with that gas here.

[sl4ck]

maybe evap bad design?
how much sould be +/- the evap temp diference between full and idle?

CPU I have -5 full, idle -30

...but I think he need help...

I need so help as i can get :(

Huh? I thought it was a little repeititve by now... but here it goes.
for r402a gas optimal 0.031 cap tubing for such compressor with load we typically use is right on 9ft 6inches. With R404a, it's actually 9ft 4 inches. (That is for NF9FX but works similar on Aspera 1/3hp 12cc compressor I played with). Typical full load evap temp with cpu running 150W with 1/3hp compressor would be from -45c to -39c depending on gas used on side of evap. If you put probe on suction line, it might get even colder reading which I haven't done for a while. I suggest putting probe closer to cpu so you are actually tuning for COOLING processor not just getting good suction return temp for optimal temp tuning. Considering size of your condenser though you might be overcharged right now. How do you charge? do you let things settle down at least 10 minutes each time you change charge?

PS) What you read on mbm for temp delta is typical I would worry more about evap temp change for time being. Than work to get best temp from mobo reading after that.

[Ssilencer]

I knew you will be jumping like that LOL (I know you) ;)
Have to go now, I will elaborate later

[sl4ck]

So i'm gonna try something like 2,85m :D

Thx all of you people

[sl4ck]

I've shorten Cap tube (lenght is now 9feet 4 inch)compressor became less noisy, evap temps are now:

-41.5 @ 160PSI @ 1,650 @ 3000Mhz Full Load

maybe system overcharged @ 160 PSI?
may my desupperheater affect temps by the negative way, having to much passages and be to much restrictive to the system?

EDIT: charged with 170PSI and Evap temp dropped to -38.8, i think my system is getting overcharged

[sl4ck]

Is it ok 170PSI for:

Idle Evap Temp: -47.5ºc
Full Evap temp: -42ºc

Idle CPU temp: -30ºc ~ -29ºc
Full CPU temp: -11ºc ~-10ºc

3700+ SD @ 3000Mhz @ 1,650v ??

i have similar setup as you my high side pressure on 404 is 160psi idle on evap is -49 with full evap temp -44 idle temps the same as yours but load temps are -16 at 3400 and 1.8v after 2 hours but no ihs on. ps if you want a opty 146 with no ihs then pm me have one for sale

Can use the same cap tube size for Danfoss NL11F?
What cap tube MachII uses? 0.028? 0.031?

[jinu117]

Can use the same cap tube size for Danfoss NL11F?
What cap tube MachII uses? 0.028? 0.031?

I haven't opened up mach in ages... I think they use 0.026?
Don't hold me to it though.
Considering I use NF9FX which is equivalent of NL11F in US... probably same hold truth :)

[sl4ck]

i asked about mach2 capilary because o want to replace it with 0.031 and r404a, but i don't want to disassembly mach 2 evap, i want to replace 0.031 cap tube with a litle bit of cap tube that came from mach 2 evap, but a can´t get a replacement lenght with the 2 kinds of cap tube
