Chilled water cooling in the making.

post #1 of 73
Thread Starter 
Hey guys, I found this 10,000BTU air conditioner in the garbage, and it works 100%. It runs on R22, and cools down extremely fast. This is the unit the way I found it, but I've worked on it today (will post pictures later of the current state). Basically, I tore down the front controls, the fan shroud and the sides, so I can mount a reservoir around the evaporator.







This will be used in my friend's PC, but I'm just building it for him. He's using a GPU with a delrin top, so we'll have to make the A/C system run constantly at about 5ºC so it doesn't crack.

Feedback would be awesome =)

This makes me think about my failed chiller

I hope you have better luck than I did!

There's quite a few things I learned in the process, so if you have any questions, feel free to ask

I know not to rush or push anything too much, because the copper tubing is delicate. Any suggestions when putting in the reservoir?

The trick is to move the reservoir as much as possible instead of the evap. The mistake I made was moving the evap into the reservoir, which is when it exploded. I would suggest using some stacked books and wood or whatever you have lying around to prop up the ac unit and mount the cooler under the evap and slowly take some of the boosters away until the evap is into the cooler.

Hope that made sense. heh

This won't only cool computers, but also drinks. (Still convincing my friend to use it with his water cooling).

Expect really, really cold drinks

Got it; the cooler box/container I found easily slides underneath the evaporator. Damn, the condenser is huge... it dumps A LOT of heat.

Yea, I found that as well. If you can get a tiny old psu and mount some fans onto the condenser, just use a mobo relay switch then that will help. It is my understanding that the closer to ambient that you can get the condenser, the colder the evap will get which = lower temps.

I'll just use the stock fan, it pushes a ton of air. I'm estimating ~250CFM.
