Blower Assembly

Abstract

An air handling unit has a blower assembly, a first interior zone, and a second interior zone and the blower assembly physically separates the first interior zone from the second interior zone. A method includes providing a cabinet configured to receive a blower assembly, inserting a blower assembly into the air duct, and closing a cabinet door of the cabinet, wherein upon closing the cabinet door, the primary air flow path from a location within the cabinet downstream of the blower assembly to a location within the cabinet upstream of the blower assembly is through a blower housing of the blower assembly. A blower assembly has a blower housing comprising at least one air inlet and at least one air outlet and a blower deck extending from the outlet, wherein the blower deck comprises at least one substantially flat component having a substantially orthogonal wall extending from the flat component.

1 . An air handling unit, comprising:
 a blower assembly;   a first interior zone; and   a second interior zone;   wherein the blower assembly physically separates the first interior zone from the second interior zone.   
     
     
         2 . The air handling unit of  claim 1 , wherein the first interior zone is associated with an input to a blower housing of the blower assembly. 
     
     
         3 . The air handling unit of  claim 2 , wherein the second interior zone is associated with a blower output of the blower housing. 
     
     
         4 . The air handling unit of  claim 3 , wherein a pressure differential between the first interior zone and the second interior zone is primarily attributable to a zone boundary between the first interior zone and the second interior zone provided by a blower deck of the blower assembly. 
     
     
         5 . The air handling unit of  claim 4 , wherein the blower deck is formed integrally with the blower housing and wherein the blower housing houses at least a portion of a motor of the blower assembly and an impeller of the blower assembly. 
     
     
         6 . The air handling unit of  claim 4 , wherein substantially the entire zone boundary is formed by components of the blower assembly. 
     
     
         7 . The air handling unit of  claim 6 , wherein at least one of the components forming the zone boundary are sloped to manage a flow of water away from an electrical component of the blower assembly. 
     
     
         8 . The air handling unit of  claim 1 , wherein the blower deck extends substantially an entire distance from a left interior wall of a blower cabinet of the air handling unit to an opposite right interior wall of the blower cabinet. 
     
     
         9 . The air handling unit of  claim 8 , wherein the blower deck extends from a blower outlet to a rear interior wall of the air handling unit. 
     
     
         10 . The air handling unit of  claim 9 , wherein the blower deck extends from the blower outlet to a front panel of the blower cabinet. 
     
     
         11 . A method of creating air pressure zones in an air handling unit, comprising:
 providing a cabinet configured to receive a blower assembly;   inserting a blower assembly into the air duct; and   closing a cabinet door of the cabinet;   wherein upon closing the cabinet door, the primary air flow path from a location within the cabinet downstream of the blower assembly to a location within the cabinet upstream of the blower assembly is through a blower housing of the blower assembly.   
     
     
         12 . The method of  claim 11 , further comprising:
 blocking air flow around the primary air flow path by spanning a blower deck of the blower assembly between the interior walls of the cabinet.   
     
     
         13 . The method of  claim 11 , wherein the blower assembly comprises a blower deck extending between at least two opposing interior walls of the cabinet. 
     
     
         14 . The method of  claim 13 , further comprising:
 sliding the blower deck into integral mounting channels of the at least two opposing interior walls of the cabinet.   
     
     
         15 . The method of  claim 14 , further comprising:
 sliding the blower deck into a third mounting channel of the interior walls of the cabinet.   
     
     
         16 . A blower assembly for an air handling unit of an HVAC system, the blower assembly comprising:
 a blower housing comprising at least one air inlet and at least one air outlet; and   a blower deck extending from the outlet, wherein the blower deck comprises at least one substantially flat component having a substantially orthogonal wall extending from the flat component.   
     
     
         17 . The blower assembly of  claim 16 , wherein the wall is located along an edge of the flat component. 
     
     
         18 . The blower assembly of  claim 17 , wherein a structural web extends between the wall and the flat component. 
     
     
         19 . The blower assembly of  claim 17 , wherein a structural web extends between the flat component and the blower housing. 
     
     
         20 . The blower assembly of  claim 16 , wherein the blower assembly comprises a first shell mated to a second shell and wherein the first shell comprises a portion of each of the blower housing and the blower deck and wherein the second shell comprises a portion of each of the blower housing and the blower deck.
