Abstract

An air handling unit (AHU) for housing a number of components used in a heating or cooling system to provide forced air for climate control in a particular structure includes a single raceway construction having both low thermal conductivity and enhanced mechanical properties for use with lifting the AHU; a single insulated panel construction having a minimum number of components as well as enhanced mechanical properties for use as the floor in an AHU compartment; to minimize costs associated with fabrication and installation.

Dependent claims

A structural member for constructing an air handling unit, the structural member comprising:

a first segment having a first end and a second end opposite the first end, the first segment including a first recessed portion being disposed adjacent the second end;
a second segment having a first end and a second end opposite the first end, the first end of the second segment being coincident with the first end of the first segment, the second segment including a second recessed portion being disposed adjacent the second end of the second segment;
a plane of symmetry coincident with the first ends of the first segment and the second segment, wherein the second segment and the second recessed portion being symmetrical with the first segment and the first recessed portion about the plane of symmetry;
a third segment having a first end and a second end opposite the first end, the first end of the third segment being coincident with the second end of the first segment;
a fourth segment having a first end and a second end opposite the first end, the first end of the fourth segment being coincident with the second end of the second segment, the second end of the fourth segment being disposed adjacent to the second end of the third segment to form an edge portion;
and
wherein the first segment, the second segment, the third segment and the fourth segment defining a closed geometry, the closed geometry extending for a predetermined length wherein the second ends of the third segment and the fourth segment form a flange portion;
and wherein the flange portion and the first segment are substantially parallel.
