Fan mounting deck for an air handling unit

Abstract

The disclosed technology includes fan mounting decks used in air handling units of heating ventilation and air conditioning (HVAC) systems. The disclosed technology can include an air handling unit having a heat exchanger coil and an axial fan housed within an enclosure. The enclosure can include a fan mount that can receive and support the axial fan when the axial fan is in a first orientation configured to direct air across the heat exchanger in a first direction and when the axial fan is in a second orientation configured to direct the air across the heat exchanger in a second direction.

What is claimed is: 
     
         1 . An air handling unit for a heating, ventilation, and air conditioning (HVAC) system, the air handling unit comprising:
 a heat exchanger coil configured to (i) receive a refrigerant circulated through the heat exchanger coil and (ii) facilitate heat exchange between the refrigerant and air directed across the heat exchanger coil:   an axial fan configured to direct the air across the heat exchanger coil; and   an enclosure configured to house the heat exchanger coil and the axial fan, the enclosure comprising:
 a first port configured to facilitate passage of air between an interior of the enclosure and an exterior of the enclosure: 
 a second port configured to facilitate passage of air between the interior of the enclosure and the exterior of the enclosure; and 
 a fan mount configured to receive and support the axial fan when the axial fan is in (1) a first orientation configured to direct the air across the heat exchanger coil in a first direction such that air enters the enclosure via the first port and exits the enclosure via the second port and (2) a second orientation configured to direct the air across the heat exchanger coil in a second direction such that air enters the enclosure via the second port and exits the enclosure via the first port. 
   
     
     
         2 . The air handling unit of  claim 1 , wherein the axial fan further comprises a fan mounting deck configured to support the axial fan, the fan mounting deck being configured to interface with the fan mount. 
     
     
         3 . The air handling unit of  claim 2 , wherein:
 the fan mounting deck comprises a mount extension, and   the fan mount comprises a recess configured to slideably receive at least a portion of the mount extension when the axial fan is in the first orientation or the second orientation.   
     
     
         4 . The air handling unit of  claim 3  further comprising a stator positioned in an airflow path downstream from the axial fan, the stator being configured to straighten an air flow path of the air. 
     
     
         5 . The air handling unit of  claim 4 , wherein the fan mounting deck is further configured to support the stator. 
     
     
         6 . The air handling unit of  claim 5 , wherein the mount extension is positioned on a plane that extends between the axial fan and the stator. 
     
     
         7 . The air handling system of  claim 5 , wherein the mount extension is attached to the stator. 
     
     
         8 . The air handling unit of  claim 2 , wherein:
 the fan mounting deck comprises a mount extension, and   the fan mount comprises a railing configured to receive at least a portion of the mount extension when the axial fan is in the first orientation or the second orientation.   
     
     
         9 . The air handling unit of  claim 8  further comprising a stator positioned in an airflow path downstream from the axial fan, the stator configured to straighten an air flow path of the air. 
     
     
         10 . The air handling unit of  claim 9 , wherein the fan mounting deck is further configured to support the stator. 
     
     
         11 . The air handling unit of  claim 10 , wherein the mount extension is positioned on a plane that extends between the axial fan and the stator. 
     
     
         12 . The air handling system of  claim 10 , wherein the stator is configured to support the axial fan. 
     
     
         13 . The air handling unit of  claim 2 , wherein the fan mounting deck comprises a rotation interface configured to rotatably attach the axial fan to the fan mounting deck and facilitate rotation of the axial fan between the first orientation and the second orientation. 
     
     
         14 . The air handling unit of  claim 13 , wherein:
 the fan mounting deck includes an aperture, and   the rotation interface is configured to facilitate rotation of the axial fan at least partially within the aperture.   
     
     
         15 . The air handling unit of  claim 14  further comprising a stator positioned in an airflow path downstream from the axial fan, the stator configured to straighten an air flow path of the air. 
     
     
         16 . The air handling unit of  claim 15 , wherein:
 the stator is attached to the axial fan, and   the rotation interface is further configured to facilitate rotation of the stator at least partially within the aperture.   
     
     
         17 . A fan mounting deck assembly for a heating, ventilation, and air conditioning (HVAC) system, the fan mounting deck assembly comprising:
 an axial fan configured to (1) direct air across a heat exchanger coil in a first direction when the axial fan is in a first orientation and (2) direct air across the heat exchanger coil in a second direction when the axial fan is in a second orientation; and   a fan mounting deck configured to support the axial fan and comprising a mount extension extending from a peripheral surface of the fan mounting deck, the mount extension configured to extend at least partially into a recess of a fan mount of an HVAC system such that the mount extension can slide into, and slide out of, the fan mount.   
     
     
         18 . The fan mounting deck assembly of  claim 17  further comprising a stator configured to straighten an air flow path of the air downstream from the axial fan.
