Abstract
A packaged terminal air conditioner (PTAC) system includes a wall sleeve in which a chassis is mounted. The wall sleeve includes a bottom configured as a drain pan to collect condensate from the chilling components of the chassis. The floor of the drain pan includes a reservoir that extends downward from the floor. The floor slopes downward from the sides of the bottom to the reservoir so that water falling onto the floor flows toward and into the reservoir where it is retained until the height of the water in the reservoir exceed a rim around the drain opening. The rim further prevents treatment pellets from falling into the drain so that they can dissolve in the water captured by the reservoir until the water level of the reservoir flushes the treated water into the drain.
