Thanks John! Glad to know.
I just got a 2ton (24K BTU) window a/c unit for my home. While researching how to extend the temp control bulb (the wire at the front of the unit), I found some interesting info on dehumidifiers from Wiki:
A specific type of air conditioner that is used only for dehumidifying is called a dehumidifier. A dehumidifier is different from a regular air conditioner in that both the evaporator and condenser coils are placed in the same air path, and the entire unit is placed in the environment that is intended to be conditioned (in this case dehumidified), rather than requiring the condenser coil to be outdoors. Having the condenser coil in the same air path as the evaporator coil produces warm, dehumidified air. The evaporator (cold) coil is placed first in the air path, dehumidifying the air exactly as a regular air conditioner does. The air next passes over the condenser coil, re-warming the now dehumidified air. Having the condenser coil in the main air path rather than in a separate, outdoor air path (as with a regular air conditioner) results in two consequences: the output air is warm rather than cold, and the unit is able to be placed anywhere in the environment to be conditioned, without a need to have the condenser outdoors.
So it look like someone could take a regular A/C unit and convert it to be a dehumidifier. The reason for doing this would be that it's pretty easy to find one on CL for cheap and you don't see too many dehumidifiers for cheap.
Although it doesn't say specific amounts, it does say that A/C will reduce the humidity when the water collected is extracted out of the house.
