Turning a window a/c unit into a chiller (56k warning)

Hey, i ususally hang arround xtreme fourms, and i thought i'd share some of my info with you guys over on this fourm.

First of all, i got a 5250btu window a/c off ebay for $31. It is a kenmore and has a LG 3/4 hp compressor.

Here is the top view of the unit.

Here is the side view of the compressor

And here is how the evap lays out. Forget the ones in blue, i was asking a question to one of the members. It sits diagonally like the red line to get max efficency by having the liquid go past though it.

This is my danner mag 5



I am not quite done with it, but i will be sure to take and post more pictures of it. I have heard it should get as low as -40c so i will have to use denatured alcahol or winter grade anti-freeze. Any questions or suggestions would be appreciated.

wow! $31 bucks, nice deal. that looks like i'll work well, only i would consider a slightly bigger RES for that evaporator to cool. post pics when you're done!

Very cool! Keep us updated, that's a great quasi-first post ^_^.

I use a mix of antifreeze/water in my chilled system. That's the main thing I'm working on improving: finding the perfect mix of coolant. The water freezes up pretty fast otherwise =/. I'd stick with a simple solution to start, that way your later experiments have a solid base to make comparisons to. Like... if you used 50%water with 50%Antifreeze... upping the AF to 75% is an easy comparison... In other words, keep with simple numbers for the first tests.

yeah, i just think its going to get so cold that it will freeze solid. btw, i have to drill holes for the water to be sucked out of and brought back in. I actually think that res is perfect. there is enough room in there for a decent ammount, and it will always stay cold. I will work on it more this weekend, but not too sure what all i'll get done. looking to find a female barb for the top of the danner mag, and an extention into a 1/2" barb on the outlet.

I worked a bit more last night and i'll have the picture up soon of what all i did.
