Ed, I've never used a fridge myself, but I have fishkeeping friends who have, simply coiling 10-20 metres of plastic hosepipe inside the fridge for heat transfer. It's not terribly efficient, but since it runs constantly, it does work. The amount of cooling depends on the setup: ambient temperature, length of hose, etc. You can get a reasonable degree of control by adjusting the fridge thermostat. The reason I've never done it is partly space issues (wife complains about tanks, the idea of old fridges standing around is unthinkable), partly because of the condensation problem - if you drop the temperature by more than a couple of degrees, this becomes a real issue.
