I really needed a fermentation chamber, but we also needed space to store frozen meats and veggies. With a top/bottom freezer/fridge, the freezer is pretty worthless once you start regulating the temperature of the refrigerator.
So I rigged it up with dual temperature controllers so that I can control the two zones independently. Now our meats stay frozen, and I can ferment ale, lager, or cold crash without worrying about the freezer thawing out.
The freezer temp controller runs the compressor. That circuit just ties into the existing thermostat on the fridge. The fridge temp controller powers a duct fan for cooling by bringing the freezer's air down and a space heater for heating in the winter.
I don't have a wiring diagram drawn, but I could produce one if anyone is interested in a similar build. I have seen one or two similar ferm chamber builds, but I figured I would post this anyway, as I haven't seen one in a top/bottom unit. And it seems not too many builds focus on providing two temperature zones.
