Murphy's Law hit me today. This is now just a test bench log.

This is going to be the sneak peak of the chiller build and all you'll get for around a week or two as I'm moving to a new house during the next two weeks.

AC unit taken apart. Radiator looking thing closest to me is the cold part, one farthest is the hot side radiator. Kind of like a TEC in a way.



Up close of the cold side radiator that will be dipped in the cooler to chill the water.



I still need to figure out a poor mans way of cutting the aluminum sheet and cutting the plastic. Ideas are welcome

Thanks guys! I have it running in the garage right now with the temperature prob stuck in a cup of hot water so that it doesn't shut off


Let's see how cold this thing can get


In the end though, I will be tuning it so that it keeps the water at a steady 5C, as my pump and waterblock are only good down to 0C. It will still be a good 10-30C drop in temps though.

Here is a nice little frost picture for you guys


It appears that straight out of the box, with NO INSULATION at all, this chiller maxes out at 18F/~-8C

Not bad at all, not bad at all




EDIT: After taking off the fan blowing on the cold side rad, I was able to hit -20F

Just curious, because me and a friend are doing the same with a 3/4 HP rotary running on R22.

Not sure on the refrigerant. All I know is that it's 5,150 BTU.

EDIT: Just added some insulation to the lines for a quick run and hit a wall at -21C! I just need to figure out a way to make the unit stop when the water temperature hits 0C and start at around 10C

Alright, just got the go ahead from Syrillian to make this a dual-log of sorts. I will be posting pictures here as he makes more progress and sends me pictures of the test bench. Stay tuned!

Syrillian is making your Test Bench

Any designs yet?

Yep







The components will be added in via the back door on hinges like this



And the pumps and reservoirs will be added on a sort of platform mounted on the side of the case.

I made some more advancement today. Minor, but still something that needed to be done.

I remove the parts of the aluminum shroud circled in blue



I did that so that I can remove the entire bottom of the front section so that I have space enough between the main unit and the cold side rad so that I can mount it in a cooler. I circled the plastic part on the bottom that would block me from putting the rad into the cooler. Well...... once I take a saw to it, it won't be blockin anymore

Just got my backplate in and installed it. Took 7C off the temps off of all 4 cores. I'm also getting closer temps as well. The temps between cores don't vary nearly as much anymore, so overall a very worthy investment.

The reason I chose that backplate is because it will be a hell of a lot easier to insulate the motherboard with that compared to having no backplate or an X style backplate.

@Syrillian, you're jacked.

I can't wait to see the final product


Luckily for us he is good spirited and has a huge heart

From what I've learned, the BTU of the unit won't make the temps any lower. It is the gas that is used that determines the lowest achievable temps. however, having a unit with more BTU will give you more headroom to add more components in to the loop without taking a performance hit.

Oh and you Canadians use "jacked" differently than us in America. Jacked is usually used in this sense "Man, that was jacked up" or "That guys' teeth are jacked"

So for us, it has a negative connotation, but anyone with an IQ above whale crap will realize what you canuks meant

LOL at the jacked comment


Also, like you said, the BTU will give the unit more capacity to cool things, not make them colder. Too bad it's only going to cool my friend's Q6600

Be careful with it. What pump and waterblock is he going to use? Delrin and pump plastic will crack if you go too far below zero.
