Air guiding strip for refrigerators
A refrigerator has an open front, an air curtain system having at least one upper air egress having an outer edge and at least one lower air-recovery ingress. The air curtain system is adapted to produce a substantially vertical air curtain over at least part of the open front of the refrigerator. The refrigerator has a plurality of shelves between the egress and the ingress a plurality of shelves between the egress and the ingress including a first shelf that has an aerofoil positioned in front of it, the first shelf being located in the upper half of the open front of refrigerator. The refrigerator also includes a second shelf that does not have an aerofoil positioned in front of it, the second shelf being located below the first shelf.

7. The apparatus of claim 1 , wherein a number of airfoils in the plurality of airfoils is one fewer than a number of shelves in the plurality of shelves.
8. The apparatus of claim 1 , wherein the plurality of shelves includes at least three shelves, at least a lowest shelf from the plurality of shelves not having an airfoil from the plurality of airfoils coupled thereto.
9. The apparatus of claim 1 , wherein the plurality of shelves includes at least four shelves, at least a lowest shelf from the plurality of shelves not having an airfoil from the plurality of airfoils coupled thereto.
10. The apparatus of claim 1 , wherein the plurality of shelves includes at least four shelves, at least a lowest two shelves from the plurality of shelves not having airfoils from the plurality of airfoils coupled thereto.
11. The apparatus of claim 1 , wherein the plurality of shelves includes at least five shelves, at least a lowest three shelves from the plurality of shelves not having airfoils from the plurality of airfoils coupled thereto.
12. An apparatus, comprising:
a housing defining an interior configured to be refrigerated;
an upper air egress configured to produce air to form an air curtain that separates the interior of the housing from an exterior of the housing;
at least three shelves disposed in the interior of the housing, no shelves other than the at least three shelves being disposed in the interior of the housing; and
a plurality of airfoils, each airfoil from the plurality of airfoils coupled to a shelf from the at least three shelves, no airfoil from the plurality of airfoils coupled to a bottom-most shelf from the at least three shelves, no airfoils other than the plurality of airfoils coupled to a shelf from the at least three shelves.
13. The apparatus of claim 12 , wherein a greater number of airfoils from the plurality of airfoils are disposed in an upper half of the housing than a lower half of the housing.
14. The apparatus of claim 12 , wherein:
the at least three shelves includes at least four shelves; and
no airfoil from the plurality of airfoils is coupled to the two bottom-most shelves from the at least four shelves.
15. The apparatus of claim 12 , wherein:
the at least three shelves includes at least six shelves; and
the plurality of airfoils includes at least five airfoils.
16. The apparatus of claim 12 , wherein a number of airfoils from the plurality of airfoils is fewer than a number of shelves from the at least three shelves.
17. The apparatus of claim 12 , wherein a number of airfoils in the plurality of airfoils is three fewer than a number of shelves in the at least three shelves.
18. The apparatus of claim 12 , wherein a number of airfoils in the plurality of airfoils is two fewer than a number of shelves in the at least three shelves.
