I have been thinking about building a fermentation chiller as I have gotten interested in brewing sakes and got caught by some unusually warm weather.
I rent and don't want to deal with the hassle of buying a chest freezer, which I will ultimately end up doing if and when I buy a house. I have seen the SOFC, and while I like this, I'm not sure I always have the freezer room and go away enough that I am not sure I would be able to replace the frozen bottles on a 2-3 day basis.
Peltier cooling devices don't seem to hold enough promise for this application. A cut away small refrigerator seems like the best bet but I am wondering if there is some type of refrigerator guts out there I am not thinking of that would include a compressor, expansion valve, cooling coil, radiator etc in a nicely package small unit.
I have been thinking maybe a very small window air conditioner would work, but I am not sure if this would provide enough cooling and it's still a little larger than what i think I need. Is there anything out there I am not thinking of? Would a window air conditioner be able to provide cooling below 50F (35F ideally) or so with a little modification?
