I am going to need to build a box to keep temps down this summer.
I don't want to deal with changing ice blocks and I want it to be cheaper than buying a chest freezer, and a temp controller.

I have a dorm fridge and a window a/c unit. I'm wondering which would be more efficient to maintain temps in the mid 60's. I think the a/c would be easier to build around, but might use way more electricity.

I'm planning to use either of those sealed to a box built from plywood and foam insulation. And I do plan on buying a temperature controller (ranco seems to be the popular choice).The temps in my basement last summer got up to about 72-73 on the really hot days.

Any thoughts or advice would be appreciated.
Primary: Spurhund Zunge (Berliner Weisse), C&C for C's (gluten free Pale Ale)
Conditioning: Pomapfelwein, Oaked Imperial Stout
Drinking: Juniper Pale Ale, Baltic Black Porter, Single Malt IPA
Planning: ?

You can use the AC unit. If it has a thermostat you should be able to set it for those temps. I believe the temp sensor monitors the incoming air.

But if you plan on getting a temp controller already, the fridge would be easier(and cheaper after the controller price) to convert.

Regarding Aust1227's post...

Sorry for the unrelated question. Noobie (me) wants to know what the glass(?) things are in the top of your carboys?

Those are just airlocks. I think they are called S-type airlocks.

Any advise offered after 10:00p.m. should be regarded as questionable

Is there a write-up on this somewhere?

Check out my sig for my project. There is also

Keep in mind you'll need a pretty good drip tray for the water run off from the fridge cutting on/off.
