Résumé

The introduction of Ecodesign criteria and energy labeling schemes in the EU has started a race for increasing the energy efficiency of commercial sales cabinets.
DTI has investigated the role of the refrigeration system and the cover glass for plug-in sales cabinets. Tests were conducted for cabinets with curved glass lids and for cabinets with horizontal flat glass lids.
By optimizing the refrigeration system and using a new compressor for R600a, the energy consumption was reduced by 24.5 %.
By installing a new glass cover with super low emissivity at the lower surface, the energy consumption was reduced by an additional 15,8 % compared to the prototype with new compressor. For horizontal glass, this creates a still layer of air under the glass which helps to reduce the heat transfer through the lids even more.
Static air freezers with horizontal lids with one layer of glass with super low emissivity coating insulate the cabinet like a solid lid or a night cover.
