How does ice become thinner in a no-frost fridge? I thought ice can't evaporate at all since, well, it's below freezing temperature and it's solid, too. In my other yes-frost fridge, the ice never becomes thinner, but thickens over time, so I have to de-frost it.
I don't believe the no-frost fridges have some patented magical mechanisms that make ice evaporate, but it has to somehow occur naturally, and they just speed up the process by drying the air. Still, I don't understand how the ice evaporates.
