I have a 20 cf stand up freezer in my garage i converted to a fermentation chamber with an stc-1000. Now that ive gotten into kegging it occurs to me i may want to chill my kegs to serving temp but still ferment my brew. since buying a 2nd freezer is not an option, I'm thinkin of building a chamber inside the freezer for this. I currently have 2 ideas and im looking for feedback.
1. chill the freezer to serving temp and warm the internal chambers. The chambers would be built out of 1/2" insulation board and lined inside with reflectix. I would also wrap a layer of reflectix around the bucket for added insulation. The buckets would be warmed with 2ft of thermal tape wrapped around the buckets under the reflectix and controlled with another stc-1000
2. build a chamber out of the same insulation board and lined with reflectix. only this time i would place the kegs inside. i would duct the freezer air directly to it and setup ducts with fans to bring air out of the "freezer" chamber and into the rest of the freezer for fermentation temps as needed.
im wondering which would be more efficient? also, would insulation board and reflectix be enough to make up a 40 degree difference in the chambers? The board is rated at R3 + whatever the reflectix inside and around the bucket would add.
