Hmm, my wife wants me to make a small space in the garage for a cold storage, mostly for winter food storage that won't freeze, but that got me thinking. There is an available corner about 4' x 6' x 6'hi that is already framed and could easily be insulated. It would be easy enough to keep above freezing in the winter, but I wonder what kind of cooling device I could install that would keep it at refrigerator temps, around 40F, in the summer. Any ideas? I was thinking about a cheap 5000 BTU window A/C but I don't think they can be set that low (well, maybe one could be modified?) I'll be glad to listen to any ideas about walk-ins or above ground cellars, etc. I could do just about anything here as long as it's above ground.
