Coleman A/Cs have slinger ring on the condenser fan. There is a delivery tube form the evaporator to a small cavity under the evaporator fan the holds the water. This way, the wet conditioner helps evaporate the water and increase efficient or at least that is the theory. Of course if you are in a humid area the extra water just runs off the roof unless your A/C gas a condensate pump.
