In my experience, clothes hung on a line in cold weather (think northeast US, with high temp maybe 10F) will freeze dry if it's sunny and there's a good breeze.

With a vacuum dryer, I don't think the problem would be freezing so much as it would be maintaining a vacuum. That is, as you pump the chamber to a vacuum, some water evaporates from the clothes and raises the pressure up to an equilibrim point, so you have to keep pumping...
