This is a very odd setup because you can never cool lower than the current dew point and cannot reduce humidity which is a very important function of AC as it makes air far more comfortable even at the same temperature. Any error will cause condensation to form. This is why AC is normally done in a way where the water in the air will condense on the cold coils and be collected and drained safely. In hot, humid conditions, a typical central air system can extract 5 to 20 gallons of water a day from the air.
