Abstract: A duct (100) comprises the molded combination of: an inlet flange (110) surrounding an inlet (102), the inlet having a height and a width; and body (112) extending from the inlet to an outlet (104) and having a body interior that laterally outwardly diverges and upwardly shifts from the inlet toward the outlet.

Abstract: A fan coil unit is provided including a cabinet formed from a plurality of panels. A fan assembly is configured to circulate air through the cabinet. A heat exchanger assembly is positioned within the cabinet. The heat exchanger assembly includes at least one heat exchanger coil arranged in a heat transfer relationship with the air circulating through the cabinet. An inner surface of at least one of the plurality of panels is partially lined with an elastomeric foam insulation so that the air circulating through the cabinet does not contact the portion of the at least one panel lined with the elastomeric foam insulation.

Abstract: A cover for a transport refrigeration unit has at least one door (150) having a body formed of an inner sheet (152) and an outer sheet (154) and a joint (156) formed between the respective peripheral edges ((153), 155) of the inner and outer sheets such that the respective peripheral edges are integrally bonded together to provide a cavity (157) between the inner and outer sheets, with at least one of the inner sheet and the outer sheet formed of a flame retardant material. In an embodiment, the inner sheet (152) is formed of a flame retardant thermoplastic olefin sheet and the outer sheet (154) is formed of a non-flame retardant thermoplastic olefin sheet.

Abstract: The front cover of a transport refrigeration unit includes a plurality of hinged access doors, with each door being formed of a pair of spaced thermoplastic olefin sheets with their edges being bonded along the entire periphery of the door to form a hollow space between the sheets without a need for foam. The edges are bonded by a thermoforming process which provides strength and rigidity to the door. Additional thermoforming bonds are made at locations other than the periphery to provide further strength and rigidity. A ribbing structure is formed in one of the sheets and extends around the periphery thereof. Further ribbing may extend transversely across the sheet in non-peripheral positions.

Abstract: A blower wheel housing for an air conditioning system is formed of a single molded element having a base section and a nozzle section with included vanes having complex shapes. This is accomplished by employing a pair of mold core elements which together form a cavity into which a plastic material is injected to form the cover with its integral nozzle and vanes, and the mold core elements are then withdrawn in opposite directions but at an angle to the direction normal to the two mold core elements to thereby accommodate the complex shapes of the vanes. In one embodiment, the top wall of the nozzle is disposed at an acute angle to the longitudinal plane of the cover, and the mold core elements are also withdrawn in a plane that is parallel to this wall.

Abstract: Provision is made for a single person to easily install a bottom panel for the cover of a transport refrigeration unit. A plurality of forwardly extending tabs are spaced on a rear frame member and corresponding pockets with horizontal slots are similarly spaced near the rear edge of the bottom panel. The bottom panel is then advanced such that the tabs fit into the slots, and then the front portion of the bottom panel is attached to the framework by a plurality of fasteners passing through front pockets of the bottom cover and into L-shaped brackets mounted on a front portion of the frame. The bottom panel is preferably formed of a thermoplastic olefin material that provides flexibility for ease of assembly but is sufficiently rigid and strong and exhibits good sound absorbing characteristics.

Abstract: A transport refrigeration unit has a front cover that includes a grille supported by and attached to a surround assembly by means of latch members.

Abstract: A transport refrigeration unit having a front grille supported by a frame and being composed of a rigid material that is subject to cracking because of vibrations being transmitted from the frame, there is provided a relatively flexible support structure surrounding the grille and supporting it in the manner which allows for the damping of vibrations so as to prevent them from reaching the grille. The flexible material is preferably a thermoplastic olefin. The manner in which the supporting structure is attached to the frame and in which the grille is attached to the supporting structure also described.

Abstract: A method of fabricating a door for a cover of a transport refrigeration unit includes the steps of forming first and second sheets of plastic material, forming a core member of foam material, assembling the core member of foam material between the first and second sheets of plastic material, and bonding the respective peripheral edges of the first and second plastic sheets together. A transport refrigeration unit has a front cover that includes a pair of front doors of composite structure. Each door is formed of an inner sheet and an outer sheet of plastic material bonded together at their respective peripheral edges about a core of preformed foam material between said first and second sheets.
