Definitions
- the invention relates to a product display cabinet, in particular a refrigerated shelf, with at least one cooled at least partially by means of a cooling air flow Goods room, with means for generating a cooling air flow and with means for Circulation of a cooling air flow.
- FIG. 1 shows a sectional representation on the side, not to scale Generic cooling rack belonging to the prior art. This shows one isolated body 1, which rests on a base 2.
- the insulated body 1 encloses a goods room in which, as a rule, several goods presentation shelves 5 are arranged.
- the warehouse floor 6 is also usually used for storage and / or the presentation of goods.
- a return air grille 9 is arranged in the lower front area of the cooling shelf, over the cooling air - represented by the arrows - as well as air from the environment of the Cooling shelf sucked in by means of a fan, not shown in FIG. 1, and can be supplied to an evaporator 7.
- the one cooled in the evaporator 7 Cooling air flow is then again via the return air duct 3 and the supply air grille 8 fed to the goods room.
- the one from the supply air grille 8 to the return air grille 9 flowing cooling air flow forms a cooling air curtain that prevents the penetration of warm Ambient air in the goods room effectively prevented.
- the rear wall 4 of the goods room be perforated so that cooling air flows through the perforated back wall 4 can enter the goods room from the return air duct 3, this portion of the Cooling air flows over the goods arranged on the goods display shelves 5 and this cools.
- the cooling air generated is thus by means of a or several fans via a comparatively complex system of air ducts and evaporators.
- the air sucked in by means of the fan or fans is in cooled the evaporator system and passes - with friction losses sheet-like air ducts on the head panel of the furniture.
- the cooling air emerges from this and - with friction losses - passes through the return air grille or the fans.
- a pressure increase of the cooling air to be circulated does not exceed 10 mbar.
- the object of the present invention is a generic Goods display furniture to indicate that in terms of its cooling technology Properties compared to the prior art is improved or optimized.
- a generic product presentation furniture in particular a generic refrigerated shelf, proposed that is characterized in that the means for circulating a cooling air flow as at least one fan, compressor and / or fan, in particular roller fan, are formed, the cooling air flow to be circulated in the fan, Compressor and / or fan experiences a pressure increase of at least 50 mbar and the flow rate of the circulating cooling air flow at the outlet of the means for circulation is at least 1 m / sec.
- the means used to circulate the Cooling air flow should be designed so that the flow rate of the circulated cooling air flow at its outlet is at least 1 m / sec.
- Cooling air lines are preferably hoses and / or ducts.
- the previously required sheet-like cooling air ducts are no longer necessary for the merchandise display furniture according to the invention.
- FIGS. 2 and 3 show not to scale, lateral Sectional representations through two possible embodiments of refrigerated shelves.
- the embodiment of the refrigerated counter according to the invention shown in FIG. 2 has a so-called. roller fan 10, which from the goods room and possibly from the Area in front of the furniture sucked in cooling air or air compressed and one downstream evaporator or evaporator system 11 supplies.
- the one in the Evaporator or evaporator system 11 is cooled in the air, a small Cross-section cooling air lines 14 and 15 a cooling air outlet area 12 supplied, this - according to a further advantageous embodiment of the invention - a cooling air mixing and / or cooling air relaxation function having.
- the Cooling air outlet area over the entire width of the product presentation furniture be provided.
- the cooling air supplied in this way must be before leaving the goods area evenly across the entire width of the goods room be distributed, for which the cooling air outlet area 12 is used. He can also be designed such that the cooling air supplied to it exits the Channels or hose lines in the cooling air outlet area 12 and / or their Exit from the cooling air outlet area 12 is relaxed, the Cooling air flow cools again advantageously during this expansion.
- cooling air outlet area 12 may have an illuminating space for the goods Lighting device 13 on.
- Cooling shelves are two roller fans 10 and 10 'in series in the rear furniture area connected. Furthermore, a cooling air system 11 'is shown schematically, which with the or the cooling air lines 14 is in thermal contact and the cooling of the in or the cooling air flow 14 is used cooling air flow.
- Such a cooling system is composed, for example, of one or more cooling coils, in which a refrigerant flows. This cooling system is also conceivable To arrange the floor area of the product presentation furniture.
