View Full Version : New chiller
This is a new chiller I started to build with a cheap Kenmore 5,200 BTU A/C
another of evap and stuff
and the O' so beatiful temp
havent done the insulation yet, but as Gary Lloyed said, anything that is below ambient needs insulation! and thats the plan :D
the evap is at a slight angle, which is good according to someone ;)
I know how you guys like pics! thank GeekGodess and jamal! nice camera too
Questions? Comments? Beers to send to put in cooler? :toast:
Next step? tuning the charge for better temps! jamal has been collecting tools and has another AC for a guinea pig to test on. Quite interesting stuff, this should get my P4 and Radeon nice and zippy :)

Thanks for the tip :toast:

That sure looks like a winner. Congrats. :D
Looks like the Kenmore model is an easy bend job. How much did it cost?
Don't pinch the cap tube just yet. Let's see what it will do first.

Nice :D
I wish I could have gotten a smaller cooler like that for mine :(

Madd stuff, what exactly is 'tuning' of a phase change system?
Thanks, well I got it somewhat sealed up atm and its sitting at -38.5c. on the low setting. I let it sit all night chillin some fluid and im still alive so it must be somewhat sealed. Also, that annoying chopping sound from the fan, I fixed that with another idea. I put a power supply on top of the plastic. Id have to show you one of the pics so you know

This is something Gary would know better then any of us I think.but you tune these A/C chillers for better temps because they are overcharged for chilling liquid, and you can get better temps if you take some of that freon out

Yea there overcharged. You need a peircing valve to let some of the refrigerent out.

YOu linked to them before, and we were using them to bend these tubes, but small problem! it will only work on lines that are straight? Ones that are looping and stuff you just cant get it on to bend! You linked to this tool in the chill AC sticky. Can you help us with what you do ?

Practice, practice, practice. :D

There is a lot more to it than just tuning the charge. I could write a book. In fact I did. :D

Going to have to show you a pic of what we were trying to do. It seriously doesnt work if the tube is bent. It works if the tube is straight though.
Another question. how warm should the compresser to be? Right under the label it is cold, and everwhere else on it, it is luke warm. Also, would you know how many HP that compressor is? we cant find any specs!
Gary Lloyd
03-14-2004, 03:47 PM
12000BTU = 1HP (roughly)

:P I dont want this thing to die. Is it ok to run this thing when certain parts are cold?

Gary sell me that book :P
It's at my website: "ACR Trouble Shooting". Covers A/C's, coolers, freezers, and cascades.

No, but the accumulator is protecting it from the liquid.

Gary, does your book show how to use tube benders to straighten a tube tied in knots? hehe...
Gary Lloyd
03-14-2004, 04:55 PM
Nope, it doesn't do that... LOL

Where can we get tube benders, can't find nottin.

Yeah, thats kinda what I was asking.
Gary one more question. After looking at those pics, are there anything I need to work on or does it all look good :confused:
Gary Lloyd

So far, so good. Fill it up, and insulate, insulate, insulate.

Techmethod, argh heavy stuff!!
Gary, when I first fire up the unit with it filled with liquid... the suction line freezes up for about 20 seconds then defrosts. The compressor is still going and all too. Then I look at the cap tube coming from the bottom of the evap coming up near suction line and its frozen instead. Then after 3 minutes the suction line freezes up like I thought its supposed to do. Is it supposed to do this?

Yep, sounds about right. :D

Say I wanted to get better temps after i tuned the charge with R22. Whats the next refrigerant to use that gets even colder and is safe to use?
Gary Lloyd
03-16-2004, 08:26 PM
One of the R502 substitutes (R408A, R404A, R507, R402A). To use R404A or R507, you will need to change the compressor oil to polyol ester (POE).
thanks :toast: ok , i think i might be an idiot. I was looking at boiling points of certain refrigerants.... and r22 was in the -41.9c area if i remeber right. Then I looked at what you said, like r404a and saw a boiling point of like -45c, thats like nothing! but then, doesnt pressure make a difference? Maybe i got this all wrong, im sure i do. If we tuned this lil kenmore AC thing, I could get much better temps then -42c? They must rate these refridgerants at the same pressure? im clueless
I figured it all out pretty much about my last post but new question! how hot shoud the compressor get? I heard 140f about? I ran this thing , and pulling down it went to a max of 96.8f... and it started dropping, and is now at 83f. Its still dropping too. This is coming from under the label on the compressor
Gary Lloyd

The temperature in compressor heaven is 140-160F/60-70C.
wow! so im way off. ATM this thing has been running for 6 hours, and ambient is 69f and the compressor is at 74f. I taped a thermal probe to the bottom of the compressor right underneath the sticker. Is it doing this because it is overcharged? :confused:

Yes.

I understand that its not hurting the compressor because the accumulator doesnt let it. The liquid puddles at the bottom of the accumulator , and a venturi effect lets the vapor go through a nozzle at the top of it preventing liquid back into the compressor. Glad to know im not hurting it.
Guess next step is tuning for better temps! :toast: lol, have never even hooked this thing to a computer yet, and im all over this. Jeez im sick:D
Gary Lloyd
03-18-2004, 04:35 AM
Hook it up to your computer. It is best to tune it under heavy load.
I want too, but my blocks dont get here till tommorow probly. Then I got to insulate. My stuff is being modded by Hell-Fire.
Oh yeah, jamal made a shrine next to his chiller. It is you and he bows too it, weird huh lol :eek: ahhh im joking but we want to be smart like you kinda
;)
wonder what temps I can get outa this beast. Sorry for all the questions im sooo n00b
Gary Lloyd
03-18-2004, 04:43 AM
First things first. Get everything set up and insulated.
I hope the Via Aqua 1300 pump will work under this liquid, because thats what im getting. im on a very tight budget, and probly cant even afford the insulation now :( ok, ill let ya know what happens when i get it under a load and how it performs,,,,,someday :rolleyes: :)

Ok , Got the chiller running at jamals and......
some Chaintec nforce2
1700 JIHB 312 DUT3C
Screwed up BH6 ram.
the results?
this chip would do 2.17ghz MAX stable on air. Its running 2.4ghz just fine at same volts.
I put a temp probe in the tank and the highest temp was -18... and I turned the pump on when it reached -30, so it dropped that much. and yes, it was insulated.

The pump should be running whenever the compressor is running.
Where's the pics?

Where's the pics? The pics are on jamals cam. I let it pull down all the way before I turned on the pump and computer, or it takes a long time to pull down with the pump on. Maybe later today he can upload them to me :)
