Thinking about different ways to pull this off. Even being completely below grade, my basement only gets to about 63, even in the winter in Denver. I could just use a stand up freezer with a temp controller, but want something a little more visually appealing. I was thinking an insulated cabinet of some sort in a bar area that we're planning on building soon. I'd like 150-200 bottle capacity, and shallower for ease of seeing everything.
Keeping it cool is the part I get stuck on though. I plan on having a kegerator/keezer in the bar, and was thinking I might be able to cool it off of that? Similar to the way a regular fridge gets its cold air from the freezer. I was thinking on having some ducting run from the keezer to the celler, and use a temp controller to power fans to blow cold air from the keezer into the cabinet. Maybe put a damper in there too. This will make the keezer work a little harder, but I'm not really worried about that since I'm just asking a device meant to maintain roughly 0 degree temps to maintain 38 and 55, albeit in a larger space. I really only need it 10 degrees below ambient, so I will insulate it and seal it off as best as I can, but mainly wondering if anyone has tried this before or if I'm completely off track somewhere in my thinking.
