Abstract
The present disclosure is directed to implementation of an environmental control unit using rotomolded techniques to fabricate the structures of the unit instead of the standard conventional sheet metal, extruded, forged, and punched parts. Such implementations will provide a lighter weight and more durable mechanical configuration that will also simplify inspection, simplify assembly/disassembly, and reduce fabrication costs. Implementations incorporate rotationally-molded interlocking structures to contain and attach the critical items of the ECU's mechanical components including the compressor, and the indoor and outdoor coils, as well as the fan and blower motor assembly. In one implementation, the rotomolded structure is strengthened and insulated (thermally and acoustically) by filling the interior void of the rotationally molded structure with a closed-cell foam.
