ok an air conditioner is exactly like a dehimidifier except they opperate fans differently. by the motions of chemisty an airconditioner has a compressor which gets hotter then hell. but on the other end when ur freon(not sure of spell) is expands its gets cold. its the process of filtering out the cool from hot. an airconditioner will suck air in (from the inside) and blow it out cold inside. and will suck air in out side and blow it back out to cool the compressor. this is why ur airconditioner hangs out ur window. if u have cetral air, then u know there are still 2 parts to the system, one out side one inside. a dehimidifier is the same thing but all the air is mixed together so the room doesnt get colder or hotter. hope it helps, alot of moisture builds up to around these things becasue ur cooling the air. So if u can find a workable system using duckting for the hot air it can work ur gonna need a catch dish for water to, this in theory should drop ur humididty too.
