I'm getting close to building a walk in cooler for beer and wine. My plan is to use a wine cellar chiller which normally can only be set as low as 50 F, but use a Johnson controller or rewire the chiller to my own controller to chill part of the room to 45 or slightly less. I'll divide the room with one of those plastic flap doors so the wine side won't be so cold.
That's the plan. But if the plan doesn't work and I'm stuck at 50 or even 55, I was thinking I could make a electric jockey box to chill my 55 degree beer down to a serving temperature. Anyone around here made an electric jockey box? Google turned up a few hits of people that have used a small dorm fridge, bucket of water, and either a stainless coil or cold plate to do this. That seems reasonable. But I was also thinking about the original cooler based jockey boxes and wondering if a thermoelectric cooler might work. Amazon sells one for just under $100. Fill it with water, add cold plate, plug it in? For that matter, what about hooking up some sort of thermoelectric cooling element directly to a cold plate?
