Check in perodically to see my progress. I have most of the components already, but I'm in search for a different compressor. I brazed the evap and cap tube today. When I leak tested it in water I found a super small leak. You can't even see it with the naked eye. I'm thinking about 7.5 feet on the cap tube as I don't have 200w it will be ok if its a little short as I have an accumulator. It will allow me to step up to a higher load without retuning. Right now I have a unlocked 2500 barton moble. With the stock clock of 1.8 it only puts out 35w. I have it at 2.2 with the stock heatsink. Hopefully on phase I will be able to get it to 2.6 or 2.8.

This is my first build. And FINALLY I have my compressor and enclosure on its way. I swapped my enclosure for a clamshell as I have an AthlonXP. The compressor is a Danfoss NF11FX. :yawn2:
I think I'm going to be building a chiller before the end of the year also.

Ok I just got the compressor. Is it supposed to feel like there is something knocking around in there? :confused: And damn that thing is heavy. Does anyone have a diagram to what goes where on the electrical connector?

There are 2 ports on the suction side. Is one just for the low side schrader? I've always seen the schrader inline with the low side.

Well things are finally starting to come together. The power supply takes up a bunch of room. With the powersupply out of the way I could move the compressor back more to make more room for the condenser. I will have to see how everything fits.

nice the compressor fitted.
Now make a switch in the front of the case.
that will power the compressor and the psu (2 pole switch). Mine is rated at 30A at 230 V

That is the cheapest way to get 12v (free). Do you have a link for what you are talking about n00b?

boshuter
09-11-2007, 06:50 PM
What size cap tube are you using? If it's .031 you should be up around 9'+ if you plan on tuning for 200w. I'm using 8' 10" on a much smaller compressor unit and it works great at 200w +.

Have you checked Radio Shack online?

Is there a reason you need a DPDT? You should just need a SPST to complete the circuit.

[XC] 2long4u
09-12-2007, 11:20 PM
One circuit for 12v and the other for 120v on the same switch. I'll have to take a closer look in the radioshack. Today I only had about 5min. There are also rocker switches. I don't think I'll go with the push button switch. They are pretty neat but they come from Taiwan.

Throw -
Single - off-on
Double - on-on

Pole - How many leads to be switched
Single - one device
Double - two devices

You could use a DPDT and just not connect one side but for simplicity sake I would just look for a DPST

It's kind of hard to see scale but there is almost no room for a de-superheater coil. It doesn't help the discharge port points right at the condenser. I got rid of the power supply. I am going to be going with a hardwired converter. (about $6)

teyber
01-04-2008, 12:21 AM
nice!
however i notice 2 things: will it work with compressor discharge going into bottum of condenser and out of top of condenser? and will a filter/drier work tilted upwards?

Great work :D i do hope you spraypaint that case, but great work.

The condenser is upside down. That is the way I got it. It works the same whichever way its mounted. I need to cut off that dryer and put a new one on the bottom. It will be like this. By the way did you ever figure what movie that pic I drew was from?

Not much going on in the phase section right now so here's a question for everyone. I have .028 captube. Everyone seems to be using .031 right now. What would be the current limitations be, if any, by sticking with the .028. Would a short piece of .028 be equivalent to a longer piece of .031?

Ya technically you can get away with it ;)
And it does work, just a length between 5 and 14ft is mostly recommended.

I didnt measure how long it is but it looks like I used about half of the 10' roll. I didn't get the quad today because I went to Fry's and they wanted $300 for it so I will get the chip from newegg for $275. But I did get 2 gigs corsair xms2 4-4-4-12 and an Asus P5K-E WiFi-AP edition mobo. I got a great deal on the memory it was normally $120, I ended up getting it for $98 with a $50 rebate. The mobo supports 45nm chips. It also supports crossfire but it will do 1 card at 16X nad the other at 4X. If I end up getting 2 video cards I will sell this one and get a X48 or 780i.

Quad is ordered today. I also bought another thermaltake 120 mm fan and 2 antec 80mm for my case as the fans in there now wont connect to the mobo. It will be nice to be able to use the case fan connectors on the mobo. It will really help clean up the wiring. I am also going to be cutting up the case bigtime for wire management! I was thinking about giving it a paint job too.

01-18-2008, 01:31 AM
as far as I see there is a 25mm fan (1"), which is to thin to work proper with condensers. try to get a 38mm (1½") thick fan instead, much more capacity without adding noice.. the issue isn't the cfm rate, ut's the capacity to force air with a pressure..

[XC] 2long4u
01-18-2008, 10:45 AM
I have a thick antec that makes no noise, but also has minimal airflow. These Thermaltake fans move 93cfm. When they are both running the difference in airflow is amazing. What I've found is the condenser will cut the amount of air that the fan can move big time. When there is a fan sandwich the airflow comes up to the rated spec of the fan. Thats why I got another Thermaltake fan to put in the front.:shrug:
Let me know if I'm missing something here. Maybe it was just the antec fan that I had. I don't have any 110v fans just 12v, don't know if that makes a difference?

About the captube:

Captubes work in a range between 1.5 an 5m. Longer is bad and shorter is bad. A shorter captube than 1.5m works more like an orifice than a captube. If this is a Danfoss FX11, I can (based on many experiments) recommend the following:

2.1m (=83") of 0.031" captube

Makes you hold about 240W at -37 C.


Regards,

Philipp

[XC] 2long4u
01-18-2008, 11:58 AM
Thanks PhilippF. If I did my math right that is just shy of 7ft. The captube was one of the harder things to braze on the evap. It is a problem that the captube heats up so quick and the evap doesn't.

n00b 0f l337
01-18-2008, 12:04 PM
Gotta keep the flame off the cap tube in my experience. Heat evaps from there base up :)

n00b 0f l337
01-18-2008, 12:10 PM
Can indeed be a pain. If your going to be playing with captube alot, or just want a very easy solution, next time drill a 3/16" hole and braze in an inch or two of 3/16" tube. Then captube can go in there ;)

PhilippF
01-18-2008, 12:35 PM
Absolutely right! Never braze the captube directly into the evap. Braze about 3/4 of an inch of 6mm copper tubing into the evap, then it is a breeze to change the captube.

n00b 0f l337
01-18-2008, 12:38 PM
Ya, but cap tube rihgt inside works well too, just need more control on your flame :)

It really looks like 3 ft.

What is that adapter you made for?

[XC] 2long4u
04-14-2008, 10:34 PM
It is for the rear suction port. The case is so tight the port points right at the wiring for the plug. The adaptor is just a 90*. It is the only thing Home Depot had. :(
This is basically the same as yours Killer. With an exception of the condenser.
What captube length did you end up with after all the changes?
The suction line will be way over 3' before I'm done. It will snake all over the case. I will have to mount the accumulator up over the compressor because there is nowhere else to put it.


Edit: How long is the suction line outside the case? I don't want to make it too long as it needs to fit nicely in the computer case.

killermiller
04-14-2008, 11:13 PM
I am guessing 5ft for the capillary. For the service port, 1/4" tubing fits right in there. I see a tube bender, just do a U and and aim it downward.

Good to see you are making progress 2long. :)
Please for gods sake replace those dam awful screw electrical joiners, they were justly made illegal in this country last millennium because they are very dodgy.

I usually purge in through the cap tube and out through the suction. You are less likely to get pin holes in your welds from pressure building up in the evap/suction because the cap tube is metering it down. Make sense?

You aren't pressure testing with air are you? :slapass:

[XC] 2long4u

Yea I'm pressure testing with air.:D :cord:
The wire nuts will be gone. I just had them there to test the compressor before I got everything together and found out it didn't work
So far every joint has not been under pressure. I just seal the captube and let it blow through.

Huge suggestion for ya mate, purge THROUGH the captube into the evap and out the suction, else you end up building pressure in the evaporator before the captube sometimes and blowing out your joints.

I am purging THROUGH a cap tube. Not the captube in the system tho. :P
I see what you are saying tho. :D
Going to go braze some more. Will post pics in a sec.

How come the braided line is so much more flexible then the bronze line?

teyber
04-15-2008, 08:41 PM
braided is supposed to go over the bronze line, braided itself won't hold any refrigerant. its for very high pressures to give it some more rigidity.

Unit is looking great :O

Did you fix that evap yet?

I don't know what's under the braid but it is SUPER flexible.
Anybody have any ideas?

Its obviously not corrugated stainless steel. What does it feel like underneath? Can you squeeze it with you fingers? Where did you get it? Might just be for a waterline.

I got it from some dude in the FS section.
When I squeeze it the braided part moves around a little.
I would use it but it is pretty short, about 18".

Holey crap is that accumulator hard to braze! :shocked:
That thing was dissipating more heat then the evap. It is the ugliest joint in the whole system. It globbed up and looks like somebody puked on it.
If I ever use another accumulator I'm going to have to borrow some oxy/actelyene. :hm:

Sh1t, I pressure checked the compressor which was full of oil with air. :D
I'm telling you guys "Everything is gonna be okay."
It has been in a 30" vacuum for 48 hours now. Any moisture that is in there is going to be a vapor. I will break vacuum with refrigerent and suck it down again. :up:
Edit: The compressor shakes the ground!!!

POE oil absorbs the moisure and becomes acidic.

[XC] 2long4u
04-18-2008, 11:52 PM
You sure thats not PAG?

killermiller
04-19-2008, 12:10 AM
All POE oils are highly hygroscopic. That is, they absorb moisture quickly and hold the moisture they absorb. Once absorbed, the moisture cannot be removed through system evacuation even at vacuum pressures of 500 microns. Therefore, it is important to prevent moisture from getting in the oil in the first place. The general recommendations for handling POE oil is to keep it in a metal container, transfer it with an oil pump and keep the container sealed except when absolutely necessary. POE oils are also irritating to the skin and a real medical concern if it comes in contact with your eyes. Gloves and safety glasses are essential items when working with this oil.
Readily absorbing moisture, as from the atmosphere.

what type of compressors use pag?

sorry not trying to go to but i know they are completely uncompatible with aluminum. What type of compressors have aluminum(gaskets?)

[XC] 2long4u

Most automotive compressors use PAG. All automotive compressors have aluminum in them. :confused:
it mentiones PAG as hygroscopic bot says nothing about POE.
http://youracauthority.com/acterms/Refrigeration_Oil_AC_Compressor_Oil_printer.shtml
Also commonly called A/C Compressor oil, every A/C system includes between 8 and 12 ounces of oil, only for the purpose of lubricating the A/C compressor. There is no other component in the A/C system that requires lubrication.

Adding or replacing refrigerant oil has become far more complicated on R-134a systems than on older R-12 systems. Older R-12 A/C systems utilized Mineral oil. Most used 525 viscosity with a few compressor manufacturers specifying a 300 viscosity oil.

When those R-12 systems are retrofitted to work with R-134a refrigerant, part of the retrofit process is to remove as much of the mineral oil and install Ester (Polyolester) oil. Ester oil was used because it was compatible with both R-12 and R-134a refrigerants and would mix with any remaining Mineral oil left in the A/C system.

Factory R-134a systems specify the use of PAG (Polyalkeline Glycol) oil. PAG oils are manufactured in a variety of different viscosities and you will have to refer to the compressor manufacturer’s guidelines to determine the proper one for each A/C system. Use caution when working with PAG oils. They are very hygroscopic. That means they attract (and hold) moisture.

A better solution to A/C compressor oil is to use synthetic replacement oils that will replace Mineral, PAG and Ester oils in all auto A/C system. These oils are non-hygroscopic and have a natural cleansing action that helps to reduce oil slugging, which is a build of oil residue on the inside of the evaporator and condenser. That oil build up starts to insulate the heat transfer and reduces cooling performance of the A/C system.

Getting impatient. I can't really finish it up until I paint the case. All I need to do is braze the flex line and braze the captube into the filter.

I just got done casting the insulation. The fit is very tight inside the enclosure. It is a little bit loose on the evap side as I used a wrist pin for the inside diameter. It would be better if I had an extra chilly one laying around. Let me know what you guys think.

This stuff expands 30 times the original size. I used 5ml of each to make 10ml total. I bought a mold release but it didn't work at all. I ended up using crisco. :D

Just like with your cookies. The grease makes it so it doesn't stick to the inside of the mold. The X-30 is very sticky and glues itself to everything it touches. It is also used to make floatation devices.
