I think you have to jumper the thermostat. Just unplugging it doesn't give the desired results.

Your unit could be different though. Try unplugging and see what happens, if that doesn't do the trick, just short it out.

OK.

I decided to insulate all the tubes. I'm pretty sure it gained me 1-2c. Hard to tell with the thermostat still working.

I should have used some black electrical tape, but I always have way more gray around leftover from work.

UPDATE: I have shorted the 2 wires to the thermostat, and when the temperature inside that box reaches -15c the compressor shuts off. What gives?

oops, I tried to edit, but I flocked it up.

EDIT:

BUT, whether I leave the thermostat open(wires cut and separated) or closed(wires shorted) it behaves the same way. It shuts off @ -15c, and back on @ +5c(box temperature).

Very strange if you ask me. What should I do?

Here is a picture of......well it's obvious. The entire probe is inside the box.

Odd that it shuts off when the probe is shorted and at -15c. I'm confused, is the evaporator submerged in coolant or did you just put the rad up against the evaporator (cold thingy on the a/c)?

At any rate, here's our buddy Gutter'z v.2 Chiller action: http://www.overclockaholics.com/foru...ead.php?t=1218

Naww it's just a box on the front of the a/c. My rad is in the box, obviously, but the a/c is still whole and the -15c is the air temp inside that box.

Like I said I tried with the wires shorted and open, but now I have lengthened the wires to the thermostat so it's easier to work with and it's right on top of a light-bulb now. The compressor should be shutting off any second unless I have it straightened out.

Yup it still shuts off at the same temperature. F$#@$##@!

Thanks for the link.

The only thing I can think of is that the entire unit, including the compressor is getting too cold to function inside that contraption.

I know spfoam1 did a best air temp of -15c in a similar setup that blew -15c air into his sealed pc case.

I've been down the road, it was fun as hell tinkering with it all every day and tweaking till I found absolute best case scenario in efficiency and setup. But, I must say, once you go Ln2/Dice Pot action, you never look back except to say "Man, I wish I skipped that whole chiller phase I went thru"

Man I'd have the a/c in the shop and the chiller built tonight, but I need to get 3 gallons @ of denatured alcohol, and antifreeze.

Heres a few pics from my quickchange action. I ran a chiller and an ducted a/c unit to the case. The cold air assisted with condensation issues and the insulation on the chiller tubes assisted in the retention of low temps.

I'm looking for my chiller build pics now.

Gonna update pics below as I find them:

That's insane....when I get some money to spend I am going to get my board all waterproofed and really start playing. That bottom picture is awesome. I want my system to look all frosty on top too.

I always used RV antifreeze and prestone windshiled washer fluid and a few drops of anti - fungal from the pet shop. It was the -50 windshield stuff i think. i never liked the idea of denatured alcohol in the system.
