Développement d'un outil de conception pour les rideaux d'air à recirculation utilisés dans les meubles frigorifiques de vente.

Development of a design tool for recirculated air curtains used on retail display cabinets.

Résumé

Recirculating cold air curtains are used to seal the open front of all multi-deck refrigerated display cabinets. Infiltration through this air curtain has been estimated to be the source of between 70 and 80% of the total heat gain to the cabinet. More efficient air curtains would not only save energy but would enable more precise temperature control of the produce within the display cabinet. Curtain thickness, length, discharge temperature and velocity all influence the efficiency of the air curtain and design optimisation has until recently been largely empirical. The aim of this study was to generate a design guide which would enable designers with limited fluid flow expertise to rapidly identify the most efficient air curtain design to seal any given cavity from fundamental measurements without any need for intensive computation.
