Abstract
A packaged air conditioner or heat pump unit is provided with an elongated removable drain pan having an inner longitudinal portion that underlies and receives condensate falling from the portion of the unit's indoor coil positioned within the conditioned air flow through the unit. An outer longitudinal portion of the drain pan underlies tubing portion return bends of the coil positioned outside of the conditioned air flow and separated from the inner longitudinal pan portion by a vertical dividing wall having a small condensate transfer hole therein. During cooling operation of the unit, the unit blower creates a negative pressure inwardly adjacent the hole which draws return bend condensation from the outer longitudinal pan portion into the inner longitudinal pan portion for drainage outwardly therefrom, with the condensate received from the balance of the coil, via a drain line connected to the pan.
