Definitions

  • the present disclosure encompasses a cold store for the display of chilled goods.
  • Such a refrigerator is from WO 2018/233770 A1 known.
  • the refrigerated space can be set up in a sales room of a supermarket or a gas station and allows goods such as food, drinks or the like to be cooled. At the same time, the cold room allows you to present your goods to customers in the supermarket or petrol station.
  • the refrigerated space has a goods presentation side with a through-opening in order to be able to see and/or remove the goods in the refrigerated space from the outside.
  • the cooling of the goods is supported by a circulating air system.

  • a refrigerated space which is suitable for cooling food, drinks or other goods, in particular refrigerated goods.
  • the cold room is also suitable for being set up in a sales room.
  • the cold storage room is suitable for being set up on a floor area of, for example, a supermarket or a gas station.

  • the refrigerated space preferably has a goods presentation side.
  • the cold room has a goods presentation function in order to present goods in the cold room to the outside, for example in the sales room, for customers.
  • a through-opening is assigned to the goods display side and/or the goods display side has a through-opening.
  • the through-opening is preferably designed for the removal of goods.

  • the refrigerated space can have at least one door element which is assigned, for example, to the goods presentation side.
  • the cold room preferably has a shelving system.
  • the shelving system is a product display shelf or has a product display shelf.
  • the shelving system is arranged inside the refrigerated space and serves, for example, to accommodate goods contained in the refrigerated space, in particular to place them thereon.
  • the shelving system comprises at least one, preferably several, in one Row of shelves arranged one below the other, which face the goods presentation side with their long side.
  • the shelves are spaced apart from the goods presentation side, for example via a first intermediate space.
  • the shelves face a second intermediate space with their longitudinal side opposite the one longitudinal side.
  • Such a shelving system supports the goods presentation function of the cold room, in that the goods placed on the shelving system can be viewed and/or removed from the outside via the goods presentation wall or its passage opening.
  • shelf is to be understood in particular as meaning a floor section of the shelving system on which goods can be placed.
  • the shelf can be flat, in particular full-surface.
  • the shelf can have or consist of a plurality of floor elements.
  • the floor elements are surface elements or roller conveyors.

  • the shelves are then aligned inclined downwards in the direction of the goods presentation side.
  • the shelves then have an extent directed downwards along their transverse sides in the direction of the goods presentation side.
  • This inclined position of the shelves makes it possible for goods placed on them to slide down, for example when goods located in the area of the lower end are removed.
  • the cooling space preferably has an air circulation system.
  • the air circulation system is set up to circulate an air flow, in particular to circulate within the refrigerated space, for example to circulate a horizontal axis parallel or essentially parallel to the goods presentation side.
  • the circulating air system comprises one or at least one fan and a nozzle device, which are flow-connected to one another.
  • the circulating air system makes it possible to clean the interior of the refrigerator compartment, in particular certain areas inside the To act on or to reach the cold room in a targeted manner with an air flow. For example, this promotes a targeted flow to areas of the shelving system, for example to reach goods stored there and/or to generate an air curtain along the goods presentation side as a barrier to air exchange via the passage opening.
  • the nozzle device prefferably has a plurality of nozzle pipes which are directed onto the first intermediate space from above. Furthermore, it is provided, for example, that the nozzle pipes are arranged one behind the other alongside the shelves, in particular in a row one behind the other.
  • a heat exchanger is assigned to the circulating air system and is set up in particular to couple the heat exchanger to a refrigeration machine or other refrigeration generator in terms of refrigeration technology.

  • the heat exchanger is directly and/or directly assigned to the fan or arranged in the immediate vicinity of it, for example arranged on the pressure side of the fan.
  • the heat exchanger is an evaporator. This makes it possible for the circulating air flow generated by the circulating air system to entrain cooled air or for the air flow to be cooled.
  • the circulating air system can have an access or connection via which cooled air can be supplied, for example from an external cold air generator.
  • the air recirculation system further includes an inflow duct.
  • the inflow channel is flow-connected, for example, to the fan and/or the nozzle device and/or the heat exchanger.
  • the inflow channel extends downwards.
  • the inflow channel is located in the second intermediate space.
  • the inflow channel has an air inlet opening, which is preferably arranged at the level of or below at least one of the shelves.
  • short-circuit flow means that the air flow leaving the nozzle device leaves the desired flow path, in particular the desired flow path between the two intermediate spaces, and instead circulates via an unwanted, shortened flow path.
  • the inflow channel extends into a lower half of the cooling chamber and the air inlet opening is preferably arranged in the lower half. This favors an extension of the flow path in the vertical direction. It has been shown that in this way lower shelves can also be reached better in terms of flow and thus improved cooling is promoted for the goods stored there.
  • the air inlet opening is arranged at a lower end or end area of the inflow duct also aims in this direction.
  • the air inlet opening has a surface pointing downwards.
  • the air inlet opening is arranged, in particular formed, on a downward-pointing side of the inflow channel.
  • the air inlet opening is arranged at a point in the inflow duct which, for a given length of extension of the inflow duct downwards, favors the greatest possible lengthening of the flow path downwards with regard to the circulating air flow blown out by the nozzle device.
  • the air inlet opening can be formed in such a way that the side of the inflow channel pointing downwards is designed to be open, ie for example the opening area of the air inlet opening corresponds or essentially corresponds to the cross-sectional area of the inflow channel.
  • the side of the inflow channel pointing downwards can also be closed.
  • the Air inlet opening arranged, in particular formed, on a side of the inflow channel pointing towards the shelves.
  • the inflow channel has at least one, preferably a large number of, further air inlet openings.
  • the further air inlet openings preferably have an opening area pointing towards the shelves, ie they are arranged, in particular formed, for example on a side of the inflow channel pointing towards the shelves. This favors at least part of the circulating air flow being distributed as a transverse flow running transversely to the vertical direction over a vertical surface area, this vertical surface area being caused by the distribution of the further air inlet openings on the inflow duct.
  • the above measures also promote the cooling of the goods placed on the shelves, since the additional air inlet openings on the inflow channel and the resulting cross-flows allow improved flow through the contact areas on the shelves.
  • This effect is also promoted, for example, by the further air inlet openings having a cross-sectional area which is smaller than the cross-sectional area of the air inlet opening.
  • the other air inlet openings are in Formed like a nozzle with respect to the cross-sectional area.
  • the additional air inlet openings have a circular cross-sectional area.
  • the further air inlet openings are distributed over a surface section of a side of the inflow channel facing the shelves, with the inflow channel having a preferably closed intermediate section on its side facing the shelves, which is arranged between the surface section with the further air inlet openings and the nozzle tubes.
  • closed intermediate section is to be understood in particular as meaning that the surface section is provided without air inlet openings, ie is designed without air inlet openings.
