Another members post got me thinking. Couldn't a mini fridge with a couple of holes cut in it work for a water chiller in a recirculating system? Used mini fridges are cheap, they dont cost much and they dont put out anything like the heat a water chiller does. Just a thought
I don't think I'd put the res in it, I'd run copper tubing in one side, coil it inside, and run it out the other side. Or hook the copper to a heat exchanger inside, that might give the water more time to cool?
I've got a fridge to use, I just never worked out the details.
