I think your article is what spurred my question. Maybe I need to read it again. But a/c and refrigeration units remove moisture, so I guess a freezing unit would do the same. When you cool air, it is like squeezing a sponge, moisture condenses somewhere. Usually at the location where it is being cooled. I wonder if there is a warm/freeze/warm/freeze cycle going on which keeps drawing out water.

I am fogetting that there is a vacume, and not circulating air. I see the problem now.
