Chilled Water Bubbler = Water Chiller?

[kommando]

I've been offered a Chilled Water Bubbler (Makes chilled water drinkable) for 30 aussie bucks and im wondering is it suitable as a waterchiller or will it needs some modifications to the evapourator to lower temps as well as a regas?

[jamaljaco]

Depends on how low you wanna go,you could probably find a window ac for the same price and do way better.Can't say much more to little info on the "bubbler". You say it makes chilled water drinkable ,but does it make the water chilled?

[kommando]

Yer it makes chilled water, like really cold.

Its a cheap method because ac's here are really expensive and second ahdn fridges are bulky to transport and this is nice n' small. But i guess i could always change some of the things n' all so it becomes better?

[chilly1]

The water chill does it have hot water also? If so disable it. The one major advantage is the two pipes already into the res of the water chiller. Remove the spigots. If you pipe the cold outlet to your pump and the warm pipe to the return line your done. Fill with antifreez and jumper the tstat out so it will go below freezing, These usually have a 1/8 or 1/10 hp compressor that will goto -20 with a load of 120 watts or so. Watchout for ice forming on the walles of the chiller. If it does generate too much you could put a small computerfan on the static condenser for a little air flow... Of course you could dismantle and repackage the entire thing, but it is not nessary nless you need the space.

Tstats?
Spigots?

Got pics of these things?

spigots are those little lever thingys where the water comes out.

[jamaljaco]

I say get the thing ,like Chilly1 said it sounds like a ready made chiller.

[kommando]

So then jsut bend copper pipign so the evap goes in the esky then it should be running niceley?

[Learn]

i' ve a chiller as you.
recover for free.

it use 1/6 hp danfoss R12.
it does -7°c loaded, and -17°c idle.
i'll change the captube, gas r12 => r22, drier and evaporator.
i hope for -20/30°c loaded

Leave it as it is only cover it and remove the spigots these are you connections the cold spigot comes from the bottom the warm one for the return. Returnes the liquid to the top.

Well

if the unit can deliver hot water also...
it could be using a peltier, and then it isn't usable (lack of power).

But if it uses a vapor change like cooling, it will be ideal for GPU cooling (direct die).

[chilly1]

These always use a resistance heater and a compressor and captube to heat and cool.. I got one in my garage... 5 gallon water cooler..

[Epsilon]

wow
i need one of those ;)
great to have new stuf, for about 20euro :)

can u sens me a dozen or something by are mail ;) :P

[Epsilon]

chilly1

what compressor is it using ?
where do u live ?

these kind of systems are far more expensive (like AC's) in europe. Why? I don't know, but it definatly sucks.

[chilly1]

I am using this one it has a 1/10 hp r134a compressor. I have a bunch of compressors here, I have a 1/10 hp 230v 50 hz compressor new and a bunch of 120v 1/7 condensers that are new. I also have 7 1/8 hp compressors that were removed from new equipment.

[Epsilon]

Well,

I'm looking for a system to cool my GPU down to about -30.
a 1/10 or 1/8hp compressor seems perfect.

and esspecially when it's that cheap
Can u give me some type numbers of compressors which i can use ? I have 230v here (netherlands).

tnx

[kommando]

Ill be using it as a waterchiller and getting it on saturday hopefully. So ill just make a box for it then put the evaporuator in the esky and i should be right?

[chilly1]

You should be able to get danfoss or aspersa compressors, you only neet to have a compressor with a 200w motor.

The bubbler should be ready to go all you should have to do is connect your pump to the inlet oand outlet spigots (remove the two handles) on the water cooler...

[Epsilon]

Well, as soon u have more info about the cooler, i really like to know more about it (type of compressor etc).

Because for 30 aus dollar, i would REALLY like to have 1 (much cheaper then here in holland).

Then i can get some info about shipping from aus to NL (well, pretty much the longest trip possible ;))

[kommando]

Im getting in contact with the guy now, saturday, 30bucks, TESTing time :D

[Epsilon]

*bump* ;)

I really like to hear some more details and the test results (that why i give this topic a bump under its *ss :)+

[kommando]

mmmm §§§§e, driving and gas started leaking so it needs a refill. Got it for free which was a plus.

Has them 2 things to put tubing through but ones bigger then the other.

[kommando]

Got some pics for ya'll

Please help me out with what to do.

Kommando, I can't tell much from your pics. Did you find out where the refrigerant leaked out?

Learn, your next project should be insulating the hoses, blocks, and boards. You also need a tight fitting lid for your reservoir.

On switching from R12 to R22, my best guess on cap tube size would be about 8 feet of .036.

Why change the evaporator?

[kommando]

Aah i know where the leak is, down near a bend near the comrpessor. Just gonna re gas it seal it etc. then should be right hoepfully.

[kommando]

Okay umm there are 2 things, which i guess i connect the hosing to. But theres no barbs. Do i barb them and hook a pump up to it and pump water through the evapourator then to the cpu etc. etc?

Also the wiring is a bit confusing so thats a problem. Could i get rid of the lines to connect the hosing up by cutting them then shutting them off and just sticking the evapourator in an esky to chill that?

[Gary Lloyd]

I have no idea what you just said, and I can't tell much from your pics. Both need a little more clarity.

[kommando]

Alright out of the big gray thing there are 4 lines, one coming from the compressor and one going to the condensor. The other 2 from my thinking are barbs where i connect my clearfex tubing up which is included in the loop of the watercooling setup. One of the pics isn't working and is a proper barb the other one seems to be a hole to screw a barb in.

So if that dosn't make sense then argh.

[Gary Lloyd]

Let's assume the big grey thing is a heat exchanger/evaporator. The tube from the evaporator to the compressor is the suction line. The tube from the bottom of the condenser to the evaporator is the liquid line, which should also have the cap tube at the evaporator end. The refrigerant flows from the cap tube end of the evaporator to the suction line end of the evaporator. The water should flow in the opposite direction, from the suction line end to the cap tube end.

Of course, this assumes that the grey thing is a heat exchanger/evaporator. If that is the case, then you won't need to stick it in an esky, which I assume is a reservoir.

[kommando]

Yer i think you got it right. Ill refill it and barb it to my tubings needs and give it a run.

Lets hope it all goes well.

[kommando]

I've decided to make this my project thread for my waterchiller so if anyone wants to see a noob in action come here.

Anyway i've started securing the system in a box. But when i was taking it out of the car i saw what caused the leakage.

Don't laugh at all this crap stuff i've got, im suuccch a noob. Only did watercooling on the christmas holidays so this a huge step.

[kommando]

I found an old fruit box which will do great to store this unit.

[kommando]

Staples.

[kommando]

Base

[kommando]

I then removed the two side peices so working on it would be easier.

[kommando]

Then tested everything in the box.

[kommando]

...

[kommando]

I then marked up the holes to hold down the compressor then drilled then found some nice big screws and put them through the back then bolted the compressor down.

[kommando]

I bent down the copper suction line (if im correct) to show what happened.

[kommando]

Screwed down the compressor and placed the condensor on the side to see how it would look. I nailed in one side peice with pvc glue applied on to the sides. Im thinking this will reduce temps because the condensor isn't getting much airflow BUT, im gonna drill a seris of holes so airflow can be produced.

[kommando]

The condensor was moving around to move so i drilled 4 holes and used string to hold it in place as i had no other way to fit it in.

In future projects ill be using a more user friendly condensor.

[kommando]

The suction line(from condensor to compressor right?) had snapped and was too long so i need to dremel it down.

[kommando]

Suction line dremeled then fitted near the connection to the compressor. Also what has been done so far.

[kommando]

I tried to get the suction line as close as possible to the connection so then i could braze it if i would ever braze.

[kommando]

While i was moving the heat exchanger (i think) i made a 180degree turn. Should i have done this?

[kommando]

The thermal-stat controller (maybe).

[kommando]

Finished product for the night.

Hope you enjoyed my §§§§ty progress.

[Gary Lloyd]

Your condenser is sideways. The tubes must be horizontal, not vertical. The line from the compressor to the top tube of the condenser is the discharge line.

Check this out:

Look for the "Samples" button.

[kommando]

Aaaaaaaahhh, okay so change it to horizontal and should make it a little bit better?

[jamaljaco]

sorry but your pics are hard on the eyes.

[kommando]

Yer i was working on night. Its a §§§§ed up system looks nothing like others :(

Anyway did some work on it today, update once i get pics resized.

[kommando]

Okay, lets get some good descriptive words into this log. Well i thought to myself that the fruit box wasn't suitable for the chiller so i asked dad for a nice peice of wood and found a nice one that was perfect. I then cut all the lines and placed all the components on the wood to see how everything would go.

[kommando]

While i was at the hardware store i picked myself up a blowtorch and some flux and solder stuff.

[kommando]

This is some weird thing which i don't know what is that is supposed to be connected up to the heatexchanger using a thin wire.

[kommando]

This is the line which connects to the above picture.

[kommando]

To secure the condensor to the base i cut up a peice of wood the size of the condensor to secure it down. To do this i would have to drill holes in and use wood screws for the peices and condensor to secure.

[kommando]

I then screwed the peice on and marked the holes to drill for the screws to secure the condensor in place.

[kommando]

I then marked up the holes for the compressor so i could secure the compressor in place. I used the same screws from the fruit box to do this.

[kommando]

Secured the compressor in place with screws then put the heat exchanger somewhere suitable just to see how it would all look. Im thinking of putting the heatexchanger in foam to insulate it.

[kommando]

Then using my blowtorch for the first time i heated up the inlets and outlets for the water to go in and out of the heatechanger. I did this because i wanted the lines to point up so securing tubing on would be alot easier.

Andd to be honest this was fkn fun ass!!

[kommando]

And... while i was playing with the blowtorch i accidently burnt a warning paper saying let air through system blah blah blah...

[Gary Lloyd]

Your condenser is still mounted wrong. Turn it 90 degrees clockwise. The tubes in the condenser must be horizontal.

You need to do some studying:

http://www.refrigerationbasics.com

Look for the "Samples" button.

[kommando]

Aahhhhh rightt, whys that.

Edit: But when i picked it up it was like that, oh god this is getting hard. Im gonna scrap this project all together if i can't make a simple thing.
