Abstract
An air conditioning system includes an air duct, an air conditioning unit in which condensation forms and a condensation drain outlet. A drain system includes a fitting having a first tube, a second tube and a third tube joined together at a common intersection. A water drain line communicates the first tube with the drain outlet. An air line communicates pressurized air from the air duct to the second tube. The third tube is communicated with the environment. The second and third tubes are oriented so that air and condensed water flow away from the intersection and through and out of the third tube. Preferably, the third tube has a down stream end which is not above its upstream end, and the first tube has a down stream end which is not above its upstream end. The tubes may form a T-shaped or a Y-shaped fitting.
