So I’m thinking about the kegerator collar I’m about to build and planning its features. I got to wondering whether anyone has tried drawing cold air from a kegerator and piping/ducting it into an external fermentation chamber. For example, have a port cut into the collar with insulated ducting, a computer fan to draw in cold air, connected to a foam insulated fermentation chamber that would sit on the floor next to the kegerator. When not needed, I would remove the ducting and cover the port in the collar.
Has anyone tried something like this before?
