A family member is building a brand new barn and she's amenable to my idea of makeshift-ing a 4'x4' (or so) closet that would be used primarily for meat ageing (I like to hunt) but also pickling and other similar stuff that a regular fridge is too small for and a restaurant-grade walk-in cooler would be too costly.
The barn is studed up and I can use a corner to implement this idea. The ceiling is high enough to hang even a cow although deer is more likely. I was planning to modify (hack) a regular window AC unit to be able to chill down to 40 deg F, I have heard this is possible and if not, I hear Cabela's sells some kind of conversion kits. The room would be against a wall facing outside so I could make an opening to fit the unit.
- Considering it is a makeshift cooler, what insulation should I put?
- Will using a regular (laminated) door with a spongy gasket around the perimeter properly seal it from the outside?
- Any ideas on how actually difficult it is to modify an AC unit for this purpose?
When not in use, I would like the closet to be modifiable for storage, e.g. have shelf support brackets etc.
