I've considered using a deep freeze, but I'm thinking I might want to expand the chamber in the future and be able to put a conical or two in it. Right now I just need it big enough for a bucket and a couple of carboys.
I think the window ac unit would be the best solution, but my wife is leaving her job and will be bringing home the tiny minifridge that we bought last summer. It's only 2 cubic feet I think, so it wouldnt really work as a kegerator. Any thoughts on using the minifridge, or should I just buy a window unit and keep bottles in the minifridge?
Any examples of similar builds would also be appreciated.
If you want to use the mini fridge, you have a couple options:
1. You can gut it, and all the cooling coils and such out of it and buid a chamber to suit.
2. You can integrate the entire fridge into a chamber per your explanation.
Many use a window A/C unit because they have a higher BTU rating, can cool quicker, and are proabably suited for more extreme environments.
A couple thiings on them though:
1. Newer units can be difficult to wire controllers to.
2. They require more energy.
3. They are louder than a mini-fridge.
4. There will be an additional cost to you, and you siad you are getting a free, or at least already paid for unit.
I'm sure there are a ton more pros and cons, but that is what came off the top of my head in the 60 seconds it took to type this!
I say go mini-fridge, build it right, and it will serve you well.
FWIW, I just finished my mini-fridge fermentation chamber about a month ago, it uses a ~4cu mini fridge (not a cube, but a vounter height).
