Abstract
A refrigerated display case 1 of the open front type has a roller mounted night cover 51 formed of flexible material which, in a deployed position, is arranged to close the front opening of the display case. The flexible material of the night cover has a plurality of apertures 54 arranged in a first section 51 that are disposed in an upper 30%-40% of the front opening. The apertures have a constant diameter D, chosen to be a fixed dimension in the range 9 mm-11 mm, that are arranged in a vertical and a horizontal grid. The spacing between the aperture centres in the vertical direction y of the grid is 3D and the spacing between aperture centres in the horizontal direction x of the grid is in the range 2D to 4D, preferably 3D. The specific dimensions of the first section and of the apertures and their grid arrangement is arranged to eliminate hotspots and improve the efficiency of the refrigeration system.
