I'm building an Kegerator/Fermentation Chamber. My plans are to drill two 4" holes into the refrigerator with a vent fan "Inductor 4 In. In-line Duct Fan" that will kick on every time the temperate gets above 50F. To pull colder air for the Kegerator into the fermentation chamber. The second hole is for the returning air to recycle warmer air. My full plans are to have a full size refrigerator "top freezer" next to the fermentation chamber.

First I'm going to try this on a small refrigerator, filled with bricks to be allowed to cool for several days before the fermentation chamber is "plugged" in. I do not want to burn out the refrigerator compressor. I'm getting the smaller refrigerator for free but I had to pay for the full size frig. I would rather keep an good Kegerator and look for something else to cool down my fermentation chamber.

Fermentation Chamber 30"Wx4'Lx4"H

What you think?

I was actually thinking about doing something similar. My fermentation chamber is under my work bench about 6 inches away from my Keezer. I was thinking about connecting the two with a 4" hose and using a fan (perhaps thru a 4" hole in the collar) to blow cold air from the Keezer to the fermentation chamber. My chamber is small so it wouldn't take much air to cool it down.

I wonder if you would need the return air? If you did, I wonder if you need it to be as large a diameter? Maybe just vent it with a one way valve somehow?

Has anyone ever tried this before?

Yeah, I've seen that when I was looking around myself, very interesting.

I found a couple of other links where they're using fans to push air. Here they are in case you hadn't seen them yet.

I'm not sure which way I'm going to go. The glycol idea seems like it could be more effecient than just pushing air. However, I'd like to use my fermenter for lagering as well. My Keezer temp is around 37 deg so I'm not sure either of these methods would be able to get to the low 40's.

Good luck with your build and let us know how it works.

Those are some noisy fans, he should have spent a few more bucks on quiet fans. If you are going to go to that level of a fermentor build you may as well go all the way and make a full on glycol jacket.

Be very careful where you drill holes in a fridge. If you hit any of the coolant likes, you just scrapped your fridge.
