A shelved cupboard for refrigerated goods comprises an opening (1) for putting in or taking out refrigerated goods (2) and a ducting arrangement (3-10) for circulating of cooled air form a cooling element (11) provided thereto. The ducting arrangement (3-10) enables cooled air to be carried in separate streams, partly in between the refrigerated goods (2) and partly past the opening (1) in order to create a screening layer. The distribution of cooled air between the refrigerated goods (2) takes place via an outlet nozzle (7) at an end of an overlying shelf (12), while the distribution of cooled air to the screening layer takes place via an outlet nozzle (10) near the upper transverse end of the opening (1). The creation of the screening layer is brought about by means of cooled air that has first been led in between the refrigerated goods (2), in order then to become somewhat less cooled than cooled air directly from the cooling element (11), whereupon such less cooled air is drawn into a ducting section (8) through perforations (13) in the back wall (12) of the goods compartment, and then passed form the perforated ducting section (8) through an upper ducting section (9) and finally distributed via the outlet nozzle (10) near the opening (1).

1. A cupboard for storing and refrigerating goods, said cupboard comprising: an opening, said opening providing access to a storage area wherein the goods are stored; a primary ducting system directing air cooled by a cooling element into said storage area to refrigerate the goods; and a secondary ducting system connected in series with said primary ducting system, said secondary ducting system collecting air from said storage area, and directing said air across said opening to create an air curtain across said opening. 2. The cupboard according to claim 1, wherein said primary ducting system comprises a lower section and a vertical section disposed along a back wall of said cupboard.3. The cupboard according to claim 1, further comprising at least one shelf for supporting the goods, said at least one shelf disposed in said storage area.4. The cupboard according to claim 3, wherein said at least one shelf comprises an air conduit communicating with said primary ducting system and conveying the cooled air from said primary ducting system into said storage area.5. The cupboard according to claim 4, wherein said at least one shelf further comprises an outlet nozzle, said outlet nozzle disposed at an end of said shelf proximate to said opening in said cupboard.6. The cupboard according to claim 4, further comprising a plurality of shelves, wherein each shelf comprises a spacer.7. The cupboard according to claim 1, further comprising a primary air fan disposed in said primary ducting system and effecting air flow through said primary ducting system.8. The cupboard according to claim 7, wherein said primary air fan is disposed in a lower section of said primary ductwork.9. The cupboard according to claim 1, wherein said cooling element comprises an evaporation battery.10. The cupboard according to claim 1, wherein said cooling element is positioned above a drip tray.11. The cupboard according to claim 1, wherein said secondary ducting system comprises a perforated section through which air from said storage area is collected.12. The cupboard according to claim 11, wherein said perforated section is disposed along a back wall of said storage area.13. The cupboard according to claim 1, wherein said secondary ducting system comprises an outlet nozzle for directing air across said opening to form said air curtain.14. The cupboard according to claim 13, wherein said outlet nozzle is disposed along a top portion of said opening.15. The cupboard according to claim 1, further comprising a secondary air fan disposed said secondary ducting system, said secondary air fan drawing air from said storage area into said secondary ducting system and forcing air from said secondary ducting system across said opening to form said air curtain.16. The cupboard according to claim 1, further comprising means for creating a secondary air curtain immediately outside of, and adjacent to, said air curtain from said secondary ducting system.17. The cupboard according to claim 16, wherein said means comprise a fan disposed in an external ducting section.18. The cupboard according to claim 1, further comprising a common outlet section uniting said primary ducting system and said secondary ducting system, wherein said primary ducting system and said secondary ducting system are selectably placed in communication with said outlet section by a dampening member.19. The cupboard according to claim 18, wherein said dampening member comprises a valve that is selectively positionable to alternatively link either said primary ducting system or secondary ducting system to said outlet member.20. The cupboard according to claim 19, wherein when said primary ducting system is linked to said outlet member, air cooled by said cooling element is directed across said opening to form an air curtain across said opening.21. The cupboard according to claim 20, wherein when said primary ducting system is linked to said outlet member, a primary air fan and a secondary air fan communicate in series to force air through said primary ducting system and said outlet member and across said opening.22. A cupboard for storing and refrigerating goods, said cupboard comprising: an opening, said opening providing access to a storage area wherein the goods are stored; a primary ducting system directing air cooled by a cooling element into said storage area to refrigerate the goods; a secondary ducting system connected in series with said primary ducting system, said secondary ducting system collecting air from said storage area and directing the collected air across said opening to create an air curtain across said opening; and a dampening member, said dampening member selectively positionable to close said secondary ducting system and open said primary ducting system, such that air from said primary ducting system bypasses said storage area and is directed across said opening to create said air curtain. 23. A method of controlling circulation of air in a refrigerated cupboard having a storage area accessible through an opening, said method comprising the steps of: directing air cooled by a cooling element into the storage area to refrigerate goods stored therein; and collecting air in series from that directed into the storage area and redirecting the collected air across said opening to create an air curtain across said opening.
