Shelved cupboard for refrigerated goods and method of controlled/regulated circulation of air in the shelved cupboard

Abstract

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).
