A temperature-controlled case is provided including a rear wall spaced apart from an intermediate wall, forming a cavity therebetween. The intermediate wall includes a first set of openings disposed below a second set of openings. A deck may be disposed proximate to the first set and the shelves proximate to the second set of openings. Each shelf may include a shelf base and cover, the cover having openings through which air may be directed. An air distribution system having an air diverting device provides for improved air flow and cooling of products within the case. The air diverting device directs a first portion of an air flow toward the deck and permits a second portion to be directed toward the shelves. The air diverting device may direct the first portion of the air flow through the cavity and towards the deck, or away from the cavity and towards the deck.

The temperature-controlled case of claim 1, wherein the air diverting device is a single air diverting device that extends substantially continuously along the rear wall. 3. The temperature-controlled case of claim 1, wherein the air diverting device comprises a plurality of air diverting devices aligned proximate the rear wall. 4. The temperature-controlled case of claim 3, wherein the rear wall includes a plurality of segments, each of the air diverting devices substantially corresponding to one of the plurality of segments of the rear wall. 5. The temperature-controlled case of claim 1, wherein the air diverting device comprises a formed sheet having a first portion generally above a second portion and a bend defining a transition therebetween. 6. The temperature-controlled case of claim 5, the first portion of the air diverting device being at least partially disposed within the cavity. 7. The temperature-controlled case of claim 6, wherein the second portion of the air diverting device is disposed at an angle relative to the first portion. 8. The temperature-controlled case of claim 6, wherein the second portion of the air diverting device is a substantially planar panel. 9. The temperature-controlled case of claim 6, wherein the air diverting device is coupled to the intermediate wall to define a plenum at least partially between the first portion of the air diverting device and the intermediate wall to substantially separate and confine air from the first portion of the air flow between the air diverting device and the intermediate wall for discharge only through the first plurality of openings, and to prevent the second portion of the air flow discharging through the first plurality of openings. 10. The temperature-controlled case of claim 9, wherein the upper barrier further defines the plenum, the upper barrier extending substantially between the first portion of the air diverting device and the intermediate wall to prevent the first portion of the air flow from flowing to the second plurality of openings. 11. The temperature-controlled case of claim 10, wherein the first plurality of openings are disposed substantially below the location at which the upper barrier and the intermediate wall converge, and the second plurality of openings are disposed substantially above the location at which the upper barrier and the intermediate wall converge. 12. A temperature-controlled case, comprising: a rear wall, a front wall, and a deck having a front portion and a rear portion;an air flow device configured to provide an air flow;an intermediate wall spaced apart from the rear wall to define a cavity;at least one shelf including a front portion and a rear portion, the rear portion of the shelf disposed adjacent to the intermediate wall; andat least one air diverting device configured to receive and direct a first portion of the air flow through the cavity and through a first pattern of openings defined by a first size, shape and spacing toward the deck and to permit a second portion of the air flow to be received in the cavity and be directed through a second pattern of openings defined by a second size, shape and spacing toward the shelf;wherein at least one of the first size, shape and spacing of the first pattern of openings is different from at least one of the second size, shape and spacing of the second pattern or openings;wherein the first pattern of openings includes an upper row of openings configured to direct a first sub-portion of the first portion of the air flow toward the rear portion of the deck and a lower row of openings configured to direct a second sub-portion of the first portion of the air flow toward the front portion of the deck. 13. The temperature-controlled case of claim 12, wherein the intermediate wall comprises a first set of openings disposed substantially below a second set of openings, and wherein the rear portion of the deck is disposed adjacent to the intermediate wall proximate the first set of openings, and the rear portion of the shelf is disposed adjacent to the intermediate wall proximate the second set of openings. 14. The temperature-controlled case of claim 13, wherein the air diverting device directs the first portion of the air flow through the first set of openings towards the deck and permits the second portion of the air flow to flow through the second set of openings toward the at least one shelf. 15. The temperature-controlled case of claim 12, wherein the first portion of the air flow flows substantially in front of the air diverting device and the second portion of the air flow flows substantially rearward of the air diverting device. 16. The temperature-controlled case of claim 12, wherein the air diverting device at least partially defines a plenum at least partially enclosing the first set of openings and thereby at least partially preventing the second portion of the air flow from flowing through the first set of openings. 17. The temperature-controlled case of claim 16, wherein a first portion of the air diverting device is at least partially disposed within the cavity substantially parallel to intermediate wall. 18. A temperature-controlled case, comprising: a front wall, a rear wall, and a deck, the deck extending at least partially between the front wall and the rear wall;an air flow device disposed beneath the deck and configured to provide an air flow;an intermediate wall spaced apart from the rear wall to define a cavity, the intermediate wall including a first plurality of openings defining a first pattern having a first size, shape and spacing, and a second plurality of openings having a second size, shape and spacing, the first pattern being different from the second pattern;at least one shelf including a front portion and a rear portion, the rear portion of the shelf disposed adjacent to the intermediate wall; andat least one air diverting device configured to receive and direct a first portion of the air flow away from the second plurality of openings and through the first plurality of openings toward the deck and configured to permit a second portion of the air flow to be directed away from the first plurality of openings and through the second plurality of openings toward the shelf;wherein the first pattern of openings includes an upper row of openings configured to direct a first sub-portion of the first portion of the air flow toward a rear portion of the deck and a lower row of openings configured to direct a second sub-portion of the first portion of the air flow toward a front portion of the deck. 19.
