Refrigeration unit

Abstract

For effective and energy-saving cooling of articles using straightforward designs, a refrigeration unit, in particular a refrigerated cabinet, freezer cabinet, refrigerated island or refrigerated counter, for storing and/or displaying articles, having a refrigeration chamber for the articles, and having a channel, which is assigned to the refrigeration chamber and is intended for supplying air, wherein two air flows can flow out of an outlet of the channel at different flow speeds and form a double protective air curtain in front of an access to the refrigeration chamber, is configured so that the channel has an element which acts on the supplied air so that the supplied air is divided up into the two air flows with different flow speeds by the element.

         2 . The refrigeration unit according to  claim 1 , wherein the element ( 8 ) is positioned inside the duct ( 2 ) or near the outlet ( 3 ) of the duct ( 2 ). 
     
     
         3 . The refrigeration unit according to  claim 2 , wherein the element ( 8 ) is embodied in a wing-like fashion to make use of a Bernoulli Effect. 
     
     
         4 . The refrigeration unit according to  claim 3 , wherein the element ( 8 ) is embodied so that in relation to the duct ( 2 ), it is adjustable and/or pivotable around an axis ( 9 ), and/or able to shift. 
     
     
         5 . The refrigeration unit according to  claim 4 , wherein the element ( 8 ) has a plurality of sections that can be adjusted and/or pivoted relative to one another. 
     
     
         6 . The refrigeration unit according to  claim 5 , wherein a guide device ( 10 ) for parallel guidance of the supplied air is provided inside the duct ( 2 ), before the element ( 8 ) in a flow direction. 
     
     
         7 . The refrigeration unit according to  claim 6 , wherein in order to guide the two air flows in parallel fashion after the element ( 8 ) in the flow direction, a guide device ( 11 ) can be positioned inside the duct ( 2 ), at the outlet ( 3 ) of the duct ( 2 ), or after the outlet ( 3 ). 
     
     
         8 . The refrigeration unit according to  claim 7 , wherein the guide device ( 10 ,  11 ) has a plurality of flat guide elements arranged parallel to one another. 
     
     
         9 . The refrigeration unit according to  claim 8 , wherein the guide device ( 10 ,  11 ) is of a plurality of individual sections ( 10 ). 
     
     
         10 . The refrigeration unit according to  claim 9 , wherein the duct ( 2 ) has at least one other outlet ( 13 ) for the supplied air opening into the refrigeration chamber ( 1 ) and the at least one other outlet ( 13 ) is embodied so that air flowing into the refrigeration chamber ( 1 ) is essentially turbulent and preferably forms a supporting air curtain for the protective air curtain. 
     
     
         11 . The refrigeration unit according to  claim 1 , wherein the element ( 8 ) is embodied in a wing-like fashion to make use of a Bernoulli Effect. 
     
     
         12 . The refrigeration unit according to  claim 1 , wherein the element ( 8 ) is embodied so that in relation to the duct ( 2 ), it is adjustable and/or pivotable around an axis ( 9 ), and/or able to shift. 
     
     
         13 . The refrigeration unit according to  claim 1 , wherein the element ( 8 ) has a plurality of sections that can be adjusted and/or pivoted relative to one another. 
     
     
         14 . The refrigeration unit according to  claim 1 , wherein a guide device ( 10 ) for parallel guidance of the supplied air is provided inside the duct ( 2 ), before the element ( 8 ) in a flow direction. 
     
     
         15 . The refrigeration unit according to  claim 1 , wherein in order to guide the two air flows in parallel fashion after the element ( 8 ) in the flow direction, a guide device ( 11 ) can be positioned inside the duct ( 2 ), at the outlet ( 3 ) of the duct ( 2 ), or after the outlet ( 3 ). 
     
     
         16 . The refrigeration unit according to  claim 6 , wherein the guide device ( 10 ,  11 ) has a plurality of flat guide elements arranged parallel to one another. 
     
     
         17 . The refrigeration unit according to  claim 6 , wherein the guide device ( 10 ,  11 ) is of a plurality of individual sections ( 10 ).
