Abstract

A heating, ventilation, and/or air conditioning (HVAC) system includes a fan deck and an enclosure cooperatively defining a track, a fan configured to direct air flow through the HVAC system, and a mount positioned in engagement with the track and in the enclosure. The mount is coupled to the fan and is configured to move along the track, thereby adjusting a position of the fan in the enclosure.

First claim

What is claimed is:

1 . A heating, ventilation, and air conditioning (HVAC) system, comprising:
a fan deck and an enclosure cooperatively defining a track; a fan configured to direct air flow through the HVAC system; and a mount positioned in engagement with the track and in the enclosure, wherein the mount is coupled to the fan and is configured to move along the track, thereby adjusting a position of the fan in the enclosure, wherein the enclosure comprises a panel, the mount comprises a plate, and the panel and the plate are configured to couple to one another to secure the position of the fan in the enclosure, wherein the fan comprises an inlet, and the inlet is configured to couple to the plate of the mount, wherein the fan is configured to draw the air flow into the enclosure along an axis of the panel, the plate, and the inlet.

2 . The HVAC system of claim 1 , wherein the fan comprises an impeller and a motor, the impeller and the motor are directly coupled to one another, and the motor is configured to drive rotation of the impeller to direct air flow through the HVAC system.

3 . The HVAC system of claim 2 , wherein the motor is an electronically commutated motor.

4 . The HVAC system of claim 2 , wherein the impeller comprises blades that extend opposite to a direction of the rotation of the impeller driven by the motor.

5 . The HVAC system of claim 1 , comprising a heat exchanger, wherein the fan is configured to direct air flow across the heat exchanger.

6 . A fan section of a heating, ventilation, and air conditioning (HVAC) system, comprising:
a fan assembly comprising a plate and a fan coupled to the plate; an enclosure comprising a panel; and a fan deck comprising a bracket, wherein the plate of the fan assembly engages with the bracket of the fan deck and the panel of the enclosure in an installed configuration of the fan assembly, wherein the plate is a first plate, the fan comprises an inlet coupled to the first plate, and the fan assembly comprises a second plate coupled to a motor, wherein the first plate is coupled to the panel such that the fan assembly is configured to draw an air flow into the enclosure along an axis of the panel, the first plate, and the inlet.

7 . The fan section of claim 6 , wherein the fan comprises a direct drive fan having the motor directly coupled to an impeller.

8 . The fan section of claim 7 , wherein the bracket of the fan deck is a first bracket, the fan deck comprises a second bracket, and the second plate of the fan assembly engages with the second bracket in the installed configuration of the fan assembly.

9 . The fan section of claim 8 , wherein the fan deck comprises a third bracket that includes a first segment and a second segment extending crosswise to one another, the first segment is coupled to a base of the second bracket, and the second plate of the fan assembly engages with the base of the second bracket and the second segment of the third bracket in the installed configuration of the fan assembly.

10 . The fan section of claim 7 , comprising an intermediate support coupled to the first plate and to the second plate.

11 . The fan section of claim 6 , wherein the bracket of the fan deck comprises a flange that extends crosswise to a surface of the panel of the enclosure, and the plate of the fan assembly engages with the flange of the bracket and the surface of the panel in the installed configuration of the fan assembly.

12 . A heating, ventilation, and air conditioning (HVAC) system, comprising:
a fan deck; an enclosure comprising a panel coupled to the fan deck; and a fan assembly comprising a mount and an inlet of a fan coupled to the mount, wherein the mount is configured to engage with the fan deck and the panel of the enclosure in an installed configuration of the fan assembly to enable an air flow into the enclosure along an axis of the mount, the panel, and the inlet, and the mount is configured to slide along the fan deck and the enclosure.

13 . The HVAC system of claim 12 , wherein the mount is configured to couple to the panel of the enclosure to block relative movement between the mount and the enclosure and between the mount and the fan deck.

14 . The HVAC system of claim 12 , wherein the enclosure comprises an additional panel coupled to the fan deck, the panel and the additional panel are oriented obliquely relative to one another, the HVAC system comprises an additional fan assembly comprising an additional mount and an additional fan coupled to the additional mount, and the additional mount is configured to engage with the fan deck and the additional panel of the enclosure in an installed configuration of the additional fan assembly.

15 . The HVAC system of claim 14 , wherein the mount is configured to engage with a first surface of the panel in the installed configuration of the fan assembly, the additional mount is configured to engage with a second surface of the additional panel in the installed configuration of the additional fan assembly, and the first surface and the second surface face toward one another.

16 . The HVAC system of claim 12 , wherein the fan comprises an impeller, and a motor is directly coupled to the impeller.

17 . The HVAC system of claim 12 , wherein the enclosure comprises an additional panel coupled to the panel and to the fan deck, wherein the panel, the additional panel, and the fan deck define a volume of the enclosure, and the fan assembly is positioned within the volume in the installed configuration of the fan assembly.
