Not really thermodynamics, more like chemistry.
Anyway when humid air encounters a cold surface, the water in the air condensates, the water vapours are in a gaseous state and become liquid.
When a wet surface Is heated the liquid water becomes gas (evaporates).
Even if idle, I doubt that any electric or electronic device can not only avoid creating heat (this is actually thermodynamics) but actually produce cold.
Ok, there are Peltier cells, still …
