         10 . The display unit of  claim 9 , wherein the supply post is a first supply post, further comprising a second supply post extending vertically along the housing and fluidly coupling the plurality of shelves to the air driver, wherein the first supply post and the second supply post are positioned on opposing sides of the plurality of shelves. 
     
     
         11 . The display unit of  claim 9 , wherein the supply post includes a plurality of baffles spaced along a height thereof to divert a portion of the air stream to each of the plurality of shelves. 
     
     
         12 . The display unit of  claim 9 , wherein the duct system includes a return post extending vertically along the housing, the return post including one or more air returns configured to draw the air curtain into the duct system. 
     
     
         13 . The display unit of  claim 12 , wherein the return post is disposed along an interior surface of the supply post, wherein the supply post includes a plurality of shelving ducts spaced along a height thereof and extending therefrom, and wherein the plurality of shelving ducts extend through the return post to the plurality of shelves. 
     
     
         14 . A display unit comprising:
 a plurality of shelves, each of the plurality of shelves having an internal volume, a first outlet positioned along a first edge thereof, and a second outlet positioned along an opposing second edge thereof; and   a duct system including:
 a first supply post including a first plurality of shelving ducts spaced along a first height thereof; 
 a second supply post including a second plurality of shelving ducts spaced along a second height thereof, the first plurality of shelving ducts and the second plurality of shelving ducts coupled to the internal volume of the plurality of shelves; 
 a first return post positioned along a first interior surface of the first supply post, the first return post including a first plurality of air returns spaced along a third height thereof, the first plurality of shelving ducts extending through the first return post; and 
 a second return post positioned along a second interior surface of the second supply post, the second return post including a second plurality of air returns spaced along a fourth height thereof, the second plurality of shelving ducts extending through the second return post. 
   
     
     
         15 . The display unit of  claim 14 , further comprising an air driver configured to provide an air stream to the duct system such that the air stream flows through the first supply post and the second supply post, through the first plurality of shelving ducts and the second plurality of shelving ducts, into the internal volume of the plurality of shelves, out of the first outlet and the second outlet of the plurality of shelves to provide an air curtain, and into the first plurality of air returns and the second plurality of air returns. 
     
     
         16 . The display unit of  claim 15 , further comprising a thermal element positioned to at least one of heat or cool the air stream.
