This works, but it may take the fridge a few cycles before the temperature of the liquid gets to the set temperature on the controller.
What it means: If the temp inside the fridge reaches the lowest setting allowed by the fridge, say 38F, it'll turn off the compressor and wait for it to warm up above the setting (probably around 40-42F). All this time, the temp inside the liquid will be dropping say from 68 down to 50F. This is when the heat transfer is occurring. Eventually the liquid will have given off all its heat, and the inside of the fridge and the liquid will reach a near-equilibrium. (near, because they will always vary a bit).
