An open-front refrigerator comprising: a display cabinet having an open face; an air circulation system comprising: an air inlet located substantially adjacent to a perimeter of the open front face; an air outlet located substantially adjacent to the perimeter of the open front face substantially opposite the air inlet , and configured to blow air across the open front face toward the air inlet such that at least some of the air blown from the air outlet is blown into the air inlet ; an air conduit for conveying air from the air inlet to the air outlet ; and an air pump configured to draw air from the air inlet , move the air thus drawn through the air conduit to the air outlet , and blow the air thus moved out of the air outlet toward the air inlet ; at least one shelf disposed within the display cabinet for placing items to be refrigerated thereon; and equipment to cool the air received at the air inlet; wherein the air conduit is arranged such that at least a portion of the air from the air inlet follows a path that passes out from a wall of the display cabinet through the at least one shelf ; and characterised in that the air conduit is further arranged such that the portion of the air from the air inlet that follows the path that passes out from the wall of the display cabinet through the at least one shelf passes back through said at least one shelf to the wall of the display cabinet, before being passed to the air outlet . a display cabinet having an open face; an air circulation system comprising: an air inlet located substantially adjacent to a perimeter of the open front face; an air outlet located substantially adjacent to the perimeter of the open front face substantially opposite the air inlet , and configured to blow air across the open front face toward the air inlet such that at least some of the air blown from the air outlet is blown into the air inlet ; an air conduit for conveying air from the air inlet to the air outlet ; and an air pump configured to draw air from the air inlet , move the air thus drawn through the air conduit to the air outlet , and blow the air thus moved out of the air outlet toward the air inlet ; an air inlet located substantially adjacent to a perimeter of the open front face; an air outlet located substantially adjacent to the perimeter of the open front face substantially opposite the air inlet , and configured to blow air across the open front face toward the air inlet such that at least some of the air blown from the air outlet is blown into the air inlet ; an air conduit for conveying air from the air inlet to the air outlet ; and an air pump configured to draw air from the air inlet , move the air thus drawn through the air conduit to the air outlet , and blow the air thus moved out of the air outlet toward the air inlet ; at least one shelf disposed within the display cabinet for placing items to be refrigerated thereon; and equipment to cool the air received at the air inlet; wherein the air conduit is arranged such that at least a portion of the air from the air inlet follows a path that passes out from a wall of the display cabinet through the at least one shelf ; and characterised in that the air conduit is further arranged such that the portion of the air from the air inlet that follows the path that passes out from the wall of the display cabinet through the at least one shelf passes back through said at least one shelf to the wall of the display cabinet, before being passed to the air outlet . <EOS>
