Abstract

An air conditioner includes an outdoor section comprising an outdoor coil, a fan, and a refrigerant compressor housed within a cabinet. The cabinet includes an outer wrapper supported by a plastic base. The base and wrapper include features that facilitate the cabinet'"'"'s assembly and shipping, enhance its appearance, and ensure its functional and structural integrity. For example, the base includes breakaway shipping tabs, lead-ins that help guide the wrapper and coil into position during assembly, and snaps that help hold the wrapper in place with a minimal number of screws. The wrapper includes watertight screw-receiving dimples for mounting electrical hardware, side panels that interconnect by way of a novel vertically sliding fit, and a spacer for protecting the coil from being crushed by the wrapper. A frame that supports the fan also supports the cabinet'"'"'s top cover.

Claims

1. An outdoor unit for an air conditioner comprising:

a base, said base being fabricated from an engineered material;

a wrapper, said wrapper being disposed above said base;

a top, said top being disposed on said wrapper, said base, said wrapper and said top cooperating to define a cabinet having an interior and an exterior;

a heat exchanger, said heat exchanger being disposed in the exterior of said cabinet;

a compressor, said compressor being disposed interior of said cabinet; and

a radio frequency identification device, said radio frequency identification device being disposed in said outdoor unit.

2. The outdoor unit according to claim 1 wherein said radio frequency identification device is embedded in said base, is self-powered and contains information relating to said outdoor section.

3. The outdoor unit according to claim 2 further comprising a query device, said query device triggering said radio frequency identification device to transmit information contained in said radio frequency identification device.

4. The outdoor unit according to claim 2 wherein the information contained in the radio frequency identification device is specific to the particular outdoor unit of which the base pan in which said radio frequency identification device is embedded is a component.

5. The outdoor unit according to claim 2 wherein said radio frequency identification device contains information relating to the manufacture and assembly of said outdoor unit.
