Abstract
Official abstract text for this publication.
An HVAC/R unit, a condensate drain pan port insert, and a condensate drain pan are provided. The condensate drain pan includes a condensate drain pan port with a port housing having an upper end and a lower end, a condensate wall extending upward from the lower end, and an air wall extending downward from the upper end and being configured to limit an airflow through the port housing.
First claim
Opening claim text (preview).
What is claimed is: 1. An HVAC/R unit, comprising: an evaporator coil; and a port configured to remove condensate away from the evaporator coil, the port, comprising: a port housing having an upper end and a lower end; a condensate wall extending upward from the lower end; and an air wall extending downward from the upper end and being configured to limit an airflow through the port housing; wherein the condensate wall is axially spaced a predetermined axial distance from the air wall to provide clearance for condensate to flow over the condensate wall; wherein a lower edge of the air wall is offset from an upper edge of the condensate wall by a predetermined, positive radial distance. 2. The HVAC/R unit of claim 1 , wherein the upper edge and the lower edge are straight. 3. The HVAC/R unit of claim 1 , further comprising a drainage opening in the condensate wall. 4. A condensate drain pan port insert, comprising: a condensate wall extending to an upper edge along a first plane; an air wall extending to a lower edge along a second plane spaced axially from the first plane and being configured to limit an airflow through the port housing; wherein the condensate wall is axially spaced a predetermined axial distance from the air wall to provide clearance for condensate to flow over the condensate wall wherein the lower edge of the air wall is offset from the upper edge of the condensate wall by a predetermined, positive radial distance. 5. The condensate drain pan port insert of claim 4 , further comprising at least one connecting member extending between the condensate wall and the air wall. 6. The condensate drain pan port insert of claim 4 , further comprising a drainage opening in the condensate wall. 7. The condensate drain pan port insert of claim 4 , further comprising an air wall support extending from the lower edge along the second plane. 8. A condensate drain pan, comprising: an outer wall having a condensate drain pan port, the condensate drain pan port having a port housing having an upper end and a lower end; a condensate wall extending upward from the lower end; and an air wall extending downward from the upper end and configured to limit an airflow through the port housing; wherein the condensate wall is axially spaced a predetermined axial distance from the air wall to provide clearance for condensate to flow over the condensate wall; wherein a lower edge of the air wall is offset from an upper edge of the condensate wall by a predetermined, positive radial distance. 9. The condensate drain pan of claim 8 , wherein the upper edge and the lower edge are straight. 10. The condensate drain pan of claim 8 , further comprising a drainage opening in the condensate wall.
