Ok, I have a dehumidifier in the basement. Actually, it was given to me, so I don’t have a manual which might give me a clue, but…I am certain the device doesn’t have a compressor. You only hear a fan running. The other day, the coil on the back was covered in a block of ice! How could this be? (My basement is a cool ~60 F)
Then, I started wondering…how does it dehumidify across this coil without a compressor to provide a cool working fluid by which to cool the air and thus dehumidify?
In short, how does this thing dehumidify, and why am I getting ice build-up? (What’s running through the coil?) No, there’s no piping to this stand-alone unit except the condensate drain is hard-piped.
Weird! A thermo mystery. I can’t believe I’ve sucked the sensible AND latent heat out of the air to create ice without some kind of prime mover! Can someone explain the seemingly impossible?
