So I picked up a portable air conditioner the other day. Its the Sharp CV-NH13 if that matters. The thing is, it's making the room very very humid. The air gets cold in the room, no problem there, but it's got to be 5 times more humid in that room than the unconditioned rooms in the rest of the house. It's not even humid outrside, just in this room. It has a built in dehumidifier but, according to the manual, does not cool if that mode is selected. Any idea why it's doing this?
