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.
Claims9
A wall sleeve for a packaged terminal air conditioner (PTAC) that is configured to be mounted in a wall opening of a wall of a structure, comprising:
- first and second opposing vertical sides which extend from a front of the wall sleeve to a back of the wall sleeve, each of the first and second vertical sides having a bottom;
- a top that extends horizontally between the first and second opposing vertical sides at a top of each of the first and second vertical sides, and which further extends from the front of the wall sleeve to the back of the wall sleeve;
- and
- a wall sleeve drain pan at a bottom of the wall sleeve that extends between the first and second opposing vertical sides at the bottom of each of the first and second vertical sides, and which sits on the bottom of each of the first and second vertical sides, and which further extends from the front of the wall sleeve to the back of the wall sleeve, wherein the wall sleeve is configured to receive therein a PTAC chassis including a chassis drain pan, wherein the wall sleeve drain pan is configured to receive condensate from the chassis drain pan, the wall sleeve drain pan having:
- a floor;
- a drain opening formed in the floor at a location that is inside the structure relative to the wall of the structure in which the wall sleeve is mounted when the wall sleeve and wall sleeve drain pan are mounted in the wall opening;
- a drain extension that extends from a bottom of the wall sleeve drain pan at the drain opening which is configured to couple to a drain fitting;
- wherein the floor slopes downward from the opposing vertical sides and the front and back of the wall sleeve to the drain opening.
