Abstract
An improved base pan is disclosed for a large ground or roof mounted "packaged" air conditioning unit. The base pan comprises a non-corrosive polymeric material but includes a section which is coated with a non-flammable substance. An airflow section of the base pan is defined by a raised platform, which, in combination with a set of ramp members, directs precipitation and condensation from the sensitive airlow section. Moisture droplets which do fall on the sensitive airflow section are directed toward a channel which uniformly slopes toward a drain hole.
Claims6
A packaged air conditioning unit comprising:
- a base pan having a top surface;
- and a unit chassis received on said base pan, wherein said unit chassis has a plurality of slits formed therein, each slit being generally flush with said top surface at a periphery thereof, said top surface being generally crowned so that moisture droplets falling in proximity with a center of said base pan are directed out of said unit through said slits.
A packaged air conditioning unit comprising:
- a base pan having a top surface;
- and a unit chassis received on said base pan, wherein said base pan top surface has a periphery and further wherein said base pan includes;
- a raised platform defining an airflow section of said base pan, said airflow section being adapted to receive compartment partitions of said unit and having an interior border along said top surface;
- and
- a plurality of ramp members formed along said interior border, said ramp members being constructed so as to direct moisture droplets falling thereon away from said airflow section.
