Hello,
I am looking to put together a glycol chiller using an old AC that we have. In fact, we have two old ACs that I've taken apart to see which would suit the project better. They are both different styles but both are 5-6k btu. Can you please assist in letting me know which AC would be best to work with?!

183038.jpg and 183054.jpg are of an AC with analog controls. It has a coil pack on both the front and back side of the unit. It has a fan that is nested and set close to the rear coils.

The remaining two pictures are of a unit with digital control. It only has the coil pack on the front. It has a larger fan in the center of the unit with coils wrapping around the rear.
It appears that this AC was used in the following build:

I understand that ACs with analog control are easier to work with. I'm not opposed to working with the digital as it can't be too difficult to mod. I really appreciate any and all input that you can provide. If I need to explain anything further please let me know.

Thanks!!!
