COOL ROOM FOR THE PRESENTATION OF CHILLED GOODS

Description

[0001] The present disclosure includes a cold storage room for the presentation of chilled goods.

[0002] Such a cold storage room is known from WO 2018 / 233770 A1. The cold storage room can be located in the sales area of ​​a supermarket or petrol station and allows for the refrigeration of goods such as food, beverages, or the like. At the same time, the cold storage room allows for the presentation of its goods to customers of the supermarket or petrol station. For this purpose, the cold storage room has a product display side with a passageway so that the goods in the cold storage room can be viewed and / or accessed from the outside.

[0003] In the cold storage room, the cooling of the goods is supported by a circulating air system. This system ensures the circulation of the cool or chilled air contained within the cold storage room.

[0004] Another cold storage room is known from US 2001 / 047660 A1.

[0005] One task is to propose at least one way to optimize a cold storage room of the type mentioned above in terms of refrigeration technology and / or airflow technology.

[0006] The problem is solved by a cold storage room which has the features of claim 1. Advantageous embodiments and / or configurations and / or aspects will become apparent from the dependent claims, the following description and the figures.

[0007] A cold storage room is proposed, suitable for cooling food, beverages, or other goods, particularly chilled goods. The cold storage room is also suitable for installation in a sales area. Specifically, it is suitable for placement on the floor of, for example, a supermarket or gas station. The cold storage room can be either walk-in or non-walk-in.

[0008] The cold storage room has a product display side. This gives the cold storage room a product display function, allowing goods stored in the cold storage room to be presented to customers outside, for example, in the sales area. The product display side has a passage opening. This passage opening is designed for the removal of goods. The passage opening is therefore designed to allow goods stored in the cold storage room to be removed from outside the cold storage room. In order to be able to close the passage opening, at least temporarily, the cold storage room can have at least one door element, which is, for example, located on the product display side.

[0009] The cold storage room has a shelving system. For example, the shelving system is a product display shelf or includes a product display shelf. Specifically, the shelving system is located within the cold storage room and serves, for example, to hold goods contained within the cold storage room, particularly to display them. The shelving system comprises several shelves arranged in a row, one below the other, with one long side facing the product display area. The shelves are spaced from the product display area by a first gap. The long side of the shelves opposite one long side faces a second gap. Such a shelving system supports the product display function of the cold storage room by allowing the goods displayed on the shelving system to be viewed and / or accessed from the outside via the product display wall or its opening.

[0010] In the present disclosure, the term "shelf" refers in particular to a section of the shelf system on which goods can be placed. The shelf can be flat, in particular a full-surface shelf. The shelf can have or consist of a plurality of shelf elements. For example, the shelf elements may be flat elements or roller tracks.

[0011] The shelving system comprises at least two elongated uprights. These at least two uprights extend vertically along their length. The at least two uprights support the shelves. At least one upright is assigned to, and in particular arranged on, each of the opposite transverse sides of the shelves. For example, the shelving system comprises more than two uprights, such as four uprights. For example, the uprights are assigned in pairs to each of the opposite transverse sides of the shelves. For example, the at least two uprights are supported on a shelf or stand on a shelf. For example, the ceiling of the cold storage room is supported on the uprights.

[0012] The shelving system can be a sliding rack system. In this case, the shelves are inclined downwards towards the product display side. Specifically, the shelves extend downwards along their transverse sides towards this side. This inclination allows merchandise to slide down, for example, when an item near the bottom is removed. Positioning the bottom of the shelves towards the product display side helps to prevent any gaps in the merchandise display area.

[0013] The cold storage room has a recirculating air system. Specifically, the recirculating air system is designed to circulate an airflow, particularly within the cold storage room, for example, around a horizontal axis parallel or substantially parallel to the product display area. The recirculating air system comprises one or at least one fan and a nozzle assembly, which are interconnected in terms of airflow.

[0014] The recirculating air system makes it possible to direct an airflow to the interior of the cold storage room, and in particular to specific areas within it. For example, this facilitates targeted airflow to areas of the racking system, such as to reach goods stored there and / or to create an air curtain along the product display side, acting as a barrier to air exchange through the access opening. Therefore, the nozzle assembly is designed to have multiple nozzle tubes directed downwards into the first space between the shelves. Furthermore, the nozzle tubes are designed to be arranged along the sides of the shelves, one behind the other, and in particular in a row.

[0015] For example, a heat exchanger is assigned to the recirculating air system and is specifically designed to be coupled to a chiller or other refrigeration unit. For example, the heat exchanger is flow-connected to the fan and / or nozzle assembly, or the heat exchanger is located in a flow path of the recirculating air system. For example, the heat exchanger is directly and / or immediately associated with the fan or located in its immediate vicinity, for example, on the fan's pressure side. The heat exchanger may, for example, be an evaporator. This allows the recirculated airflow generated by the system to carry cooled air, or for the airflow to be cooled. Alternatively, the recirculating air system may have an inlet or connection through which cooled air, for example, from an external cold air generator, can be supplied.

[0016] The recirculating air system further comprises an inlet duct. The inlet duct is, for example, connected to the fan and / or the nozzle assembly and / or the heat exchanger. The inlet duct is designed to extend downwards. It is further designed to be located in the second intermediate space. Finally, the inlet duct is designed to have an air inlet opening, which is arranged at the level of or below at least one of the shelves.

[0017] It has been shown that such an inlet channel counteracts any potential short-circuiting of the recirculated airflow. A desired airflow path, particularly in the vertical direction and especially along the product display side, can thus be better maintained. This also allows for improved airflow around the products in the cold storage room. It has been observed that the inlet channel reduces any potential cold air losses through the opening. Overall, improved cooling of the products placed on the shelves has been observed.

[0018] In the present disclosure, the term "short-circuit current" means that the airflow leaving the nozzle device leaves the intended flow path, in particular the intended flow path between the two spaces, and instead circulates via an unintended, shortened flow path.

[0019] In one embodiment, the inlet channel extends into the lower half of the cooling compartment, and the air inlet opening is preferably located in this lower half. This facilitates a vertical extension of the flow path. It has been shown that this method allows for better airflow to reach lower shelves, thus improving the cooling of goods stored there.

[0020] This is also the aim of a further embodiment in which the air inlet opening is arranged at a lower end or end region of the inlet duct. For example, the air inlet opening has a downward-facing surface. In this case, the air inlet opening is thus arranged on a downward-facing side of the inlet duct, and is specifically designed as such. This places the air inlet opening at a point in the inlet duct which, given the downward length of the inlet duct, promotes the greatest possible downward extension of the flow path with regard to the recirculated airflow blown out by the nozzle assembly.

[0021] The air inlet opening can be configured such that the downward-facing side of the inlet duct is open, meaning, for example, that the opening area of ​​the air inlet corresponds to, or substantially corresponds to, the cross-sectional area of ​​the inlet duct. Alternatively, the downward-facing side of the inlet duct can also be closed. In this case, the air inlet opening is located on the side of the inlet duct facing the shelves, and is specifically designed as such.

[0022] According to a further embodiment, the inlet duct has at least one, preferably a plurality of, additional air inlet openings. Preferably, these additional air inlet openings have an opening surface facing the shelves, i.e., they are arranged, for example, on a side of the inlet duct facing the shelves. This facilitates the flow of at least a portion of the recirculated air as a transverse flow perpendicular to the vertical direction, distributed over a vertical surface area. This vertical surface area is created by the distribution of the additional air inlet openings on the inlet duct. A similar approach is taken, for example, by arranging the additional air inlet openings vertically in horizontal rows, with the horizontal rows of additional air inlet openings extending along the sides of the shelves.

[0023] The aforementioned measures also promote the cooling of goods placed on the shelves, as the additional air inlet openings on the inlet duct and the resulting cross-flows improve air circulation across the contact areas on the shelves. This effect is further enhanced, for example, by the fact that the additional air inlet openings have a cross-sectional area smaller than that of the main air inlet opening. For instance, the additional air inlet openings are nozzle-shaped with respect to their cross-sectional area. For example, the additional air inlet openings have a circular cross-sectional area.

[0024] In a further embodiment, the additional air inlet openings are distributed over a section of the surface of a side of the inlet duct facing the shelves. The inlet duct has a preferably closed intermediate section on this side, located between the surface section with the additional air inlet openings and the nozzle tubes. The term "closed intermediate section" means, in particular, that the surface section is free of air inlet openings. This ensures that the crossflow of the recirculated air stream caused by the additional air inlet openings is only achieved at a predetermined vertical distance from the nozzle tubes, which is determined by the intermediate section. The intermediate section thus counteracts unwanted short-circuit currents.

[0025] The inlet channel is designed to have a width along the side of the shelves that is less than the distance between the shelves on opposite sides. In this respect, the width of the airflow channel is less than the distance between the shelf supports spaced along the sides of the shelves. Furthermore, the opening on the product display side is dimensioned such that the width of the inlet channel is less than the clear width of the opening. This offers advantages during installation, as the inlet channel can still be installed, for example, via the opening on the product display side, even after the shelf supports have been erected. This also facilitates the retrofitting of a cold storage room with the inlet channel.

[0026] In another embodiment, the shelving system is extended by additional shelves. In this case, for example, the row of shelves arranged one below the other forms a first shelf row, and the shelving system has a second shelf row with shelves arranged one below the other, wherein preferably the first shelf row and the second shelf row are arranged next to each other in a vertical direction.

[0027] For example, in this embodiment, the nozzle pipes are arranged one behind the other along the shelves of the first shelf row and along the shelves of the second shelf row, in particular in a single row. For example, the inlet duct is also arranged between the at least two shelf supports for the first shelf row. For example, the inlet duct then has lateral air inlet openings, which are arranged on a transverse side of the inlet duct facing the second shelf row. The lateral air inlet openings facilitate and / or improve the flow of recirculated air through the second shelf row without the inlet duct being located along the shelves of the second shelf row or extending into the second shelf row.

[0028] In a further embodiment, the shelving system is extended by additional shelves. In this case, the shelving system can have at least a third row of shelves arranged one above the other. In particular, the first, second, and third rows of shelves are then arranged vertically next to each other, with the first row of shelves positioned between the second and third rows.

[0029] For example, in this embodiment, the nozzle pipes are arranged along the sides of the shelves of the first shelf row, along the sides of the shelves of the second shelf row, and along the sides of the shelves of the third shelf row, one behind the other, in particular in a row. For example, the inlet duct is also arranged between the at least two shelf supports for the first shelf row. For example, the inlet duct has additional lateral air inlet openings, which are arranged on a transverse side of the inlet duct facing the third shelf row. These additional lateral air inlet openings facilitate and / or improve the flow of recirculated air through the third shelf row without the inlet duct being located along the sides of the shelves of the third shelf row or extending into the third shelf row.

[0030] Another embodiment consists of the fan being housed in a duct section, preferably horizontal. In particular, the duct section is located horizontally between the nozzle assembly and the inlet duct. Specifically, the duct section is positioned above the top shelf, for example, in the area of ​​the ceiling of the cold storage room and / or near the ceiling. This places the duct section in an area of ​​the cold storage room that is only minimally or not at all disruptive to the racking system or the goods stored therein.

[0031] The heat exchanger described above can be assigned to the duct section, and in particular, arranged within it. Specifically, the heat exchanger is arranged downstream of the fan in the direction of airflow, i.e., on the pressure side. For example, the duct section forms a pre-assembled unit with the fan and, in particular, the heat exchanger. This simplifies the installation of the recirculating air system.

[0032] In particular, the channel section running lengthwise along the shelves has a width that is smaller than the distance between the opposite transverse sides of the shelves. Therefore, the width of the channel section is smaller than the distance between the shelf supports spaced lengthwise along the shelves. For example, the width of the channel section corresponds to the width of the inlet channel. This also offers advantages during installation, as the channel section can still be installed, for example, via the access opening on the product display side, even after the shelf supports have been erected. This also simplifies the retrofitting of a cold storage room with the inlet channel.

[0033] In another embodiment, the inlet channel is attached to a rear wall of the cold storage room opposite the product display side. For example, the inlet channel is open along one side, which is located, for instance, opposite the side facing the shelves. This open side is then closed, particularly airtight, by the rear wall of the cold storage room. This facilitates a technically simple and / or cost-effective manufacturing of the inlet channel. Furthermore, it simplifies the attachment of the inlet channel and / or the sealing of the open side, as the existing rear wall of the cold storage room is used for this purpose.

[0034] For example, the inlet duct has a polygonal cross-sectional contour. For example, the inlet duct is made of or consists of a metal or metal alloy, particularly if it has a square cross-sectional contour. In this case, the cross-sectional contour of the inlet duct can be produced by bending a blank. For example, the inlet duct is a sheet metal part. In this case, the cross-sectional contour of the inlet duct can be produced by bending a sheet of metal. This facilitates simple and cost-effective production of the desired cross-sectional contour.

[0035] Additionally or alternatively, the duct section described above, which accommodates the fan, can have a polygonal cross-sectional contour. For example, the duct section may be made of or consist of a metal or metal alloy, particularly if it has a rectangular cross-sectional contour. In this case, the cross-sectional contour of the duct section can be produced by bending a blank. Alternatively, the duct section may be a sheet metal part. In this case, the cross-sectional contour of the duct section can be produced by bending a sheet of metal. This facilitates simple and cost-effective production of the desired cross-sectional contour.

[0036] In another embodiment, the cold storage room includes an additional product display area, an additional shelving system, and an additional air circulation system. Specifically, the additional product display area, the additional shelving system, and the additional air circulation system are arranged symmetrically to the product display area, the shelving system, and the air circulation system with respect to the longitudinal center plane of the cold storage room. The additional product display area can be designed in the same way as the product display area. The additional shelving system can be designed in the same way as the shelving system described above. The additional air circulation system can be designed in the same way as the air circulation system described above. This allows for the simple realization of a cold storage room that enables product display on two opposite sides and provides cooling optimized for this configuration.

[0037] In such a cold storage room, the inlet duct of the recirculating air system and the inlet duct of the additional recirculating air system may be mounted opposite each other. Preferably, the inlet duct of the recirculating air system and the inlet duct of the additional recirculating air system are flow-separated from each other to prevent an undesirable flow short circuit between the two inlet ducts. If the inlet duct of the recirculating air system and the inlet duct of the additional recirculating air system are open along their length, a partition is, for example, interposed to achieve flow-separation of the inlet ducts.

[0038] The air circulation system may be attached to the walls of the cold storage room, in particular exclusively to the walls of the cold storage room. Alternatively or additionally, the air circulation system may be attached to the at least two shelf supports, in particular directly or indirectly via intermediate elements. The air circulation system may also be attached exclusively to the at least two shelf supports.

[0040] Figure 1Figure 1 shows a possible embodiment of a cold storage room 1 in a front view. The cold storage room 1 is suitable for installation in a sales area, for example, of a supermarket or a gas station. The cold storage room 1 allows for the cooling of goods such as food, beverages, or the like. At the same time, the cold storage room 1 allows for the external presentation of its goods. For this purpose, the cold storage room 1 has a product display side 10.

[0041] The cold storage room 1 has a passage opening 11 on the product display side 10. The passage opening 11 is dimensioned such that goods located in the cold storage room 1 can be accessed and / or viewed from the outside. For example, the product display side 10 is open through the passage opening 11, in particular, completely open. Door elements 12 can be assigned to the product display side 10 to close the passage opening 11. For example, the door elements 12 are partially transparent or see-through, so that when the door elements 12 are closed, the goods located in the cold storage room 1 are visible from the outside. For example, the door elements 12 are glass doors whose surface is at least partially made of or consists of glass. For example, the door elements 12 are designed as a swing door or a sliding door.

[0042] The Figure 1Figure 1 shows the cold storage room 1 as an example with the door elements 12, some of which are shown in an open position and some in a closed position. Figure 2 Figure 1 shows the cold storage room 1 in a perspective view from the front, where the door elements 12 are not shown for the sake of simplicity. Figure 3 Figure 1 further shows the cold storage room 1 in a cross-sectional view with the door elements 12, which are located there in an open position.

[0043] As from the Figures 1 to 3As can be seen, the cold storage compartment 1 has a bottom 2, a top 3, a front 4, and a back 5, which preferably extend along the same spatial axis A. Viewed from the front 4, the cold storage compartment 1 has a left side 6 and a right side 7, which preferably align transversely to the spatial axis A. Preferably, the bottom 2 and the top 3 are horizontal or lie in a horizontal plane. Preferably, the front 4, the back 5, the left side 6, and the right side 7 are vertical or lie in a vertical plane. The product display side 10 is associated with the front 4. Preferably, the product display side 10 is located on the front 4 and / or corresponds to the front 4.

[0044] Preferably, the cold storage compartment 1 is bounded downwards, i.e., towards the underside 2, by a floor 2.1. The floor 2.1 can be an integral part of the cold storage compartment 1 or be formed by the floor of a room in which the cold storage compartment 1 is installed. Preferably, the cold storage compartment 1 is bounded upwards, i.e., towards the top 3, by a ceiling 3.1. The cold storage compartment 1 is bounded to the rear, i.e., towards the back 5, by a rear wall 5.1. Preferably, the cold storage compartment 1 is bounded laterally, i.e., towards the left side 6 and / or the right side 7, by a side wall 6.1 and 7.1, respectively. Preferably, the cold storage compartment 1 is bounded to the front, i.e., towards the front 4, by a front wall and / or the door elements 12 described above.

[0045] The floor 2.1 and / or the ceiling 3.1 and / or the rear wall 5.1 and / or at least one of the side walls 6.1, 7.1 can be formed by one or more wall elements. The wall elements can be lightweight components. This facilitates on-site assembly of the cold storage room 1.

[0046] The cold storage room 1 contains a shelving system 30. The shelving system 30 comprises several shelves 31.1, which are arranged in a row. One long side 32 of the shelves 31.1 faces the product display side 10 and is separated from it by a first gap 13.1. The long side 33 opposite one long side 32 of the shelves 31.1 faces a second gap 13.2, for example, from the rear wall 5.1 via the second gap 13.2.

[0047] The racking system 30 comprises at least two uprights 36, 37, which extend vertically between the underside 2 and the top 3 and support the shelves 31.1. For example, the uprights 36, 37 are supported at one longitudinal end on the floor 2.1. For example, the uprights 36, 37 are attached at an opposite longitudinal end to the ceiling 3.1 and / or the ceiling 3.1 is supported against or rests on the uprights 36, 37. Preferably, the at least two uprights 36, 37 are each assigned to one of the transverse sides 34, 35 of the shelves 31.1. For example, one upright 36 is assigned to one transverse side 34 of the shelves 31.1. For example, the other shelf support 37 is assigned to the other transverse side 35 of the shelves 31.1.

[0048] In addition to the shelf supports 36, 37, further shelf supports 36.1 and 37.1 can be provided to support the shelves 31.1. Preferably, at least two of the shelf supports 36, 36.1, 37, 37.1, in particular shelf supports 36 and 36.1 on the one hand and shelf supports 37 and 37.1 on the other hand, are each assigned to one of the transverse sides 34, 35 of the shelves 31.1.

[0049] The shelving system 30 can further comprise one or more shelf extensions. For example, the row with the shelves 31.1 arranged one below the other forms a first shelf row 40.1, and the shelving system 30 has a second shelf row 40.2 with shelves 31.2 arranged one below the other. Preferably, in this case, the first shelf row 40.1 and the second shelf row 40.2 are arranged next to each other in the vertical direction and / or, viewed transversely to the spatial axis A, the second shelf row 40.2 is arranged laterally to the first shelf row 40.1.

[0050] The at least one shelf support 36 or 36.1, which is assigned to the shelves 31.1 of the first shelf row 40.1 on one of their transverse sides 34, can be used as a support for the shelves 31.2 of the second shelf row 40.2. For example, the shelves 31.2 of the second shelf row 40.2 are, on one side, facing the at least one shelf support 36 or 36.1 with one of their transverse sides 35, and preferably, at least one further shelf support 36' or 36.1' is assigned to the shelves 31.2 of the second shelf row 40.2 on their other transverse side 34, which is, for example, located on the outside of the racking system 30.

[0051] Additionally, the racking system 30 can have a third row of shelves 40.3 with shelves 31.3 arranged one below the other. Preferably, in this case, the first row of shelves 40.1, the second row of shelves 40.2, and the third row of shelves 40.3 are arranged next to each other in the vertical direction, and, for example, the first row of shelves 40.1 is arranged between the second row of shelves 40.2 and the third row of shelves 40.3.

[0052] The at least one shelf support 37 or 37.1, which is assigned to the shelves 31.1 of the first shelf row 40.1 on one of their transverse sides 35, can be used as a support for the shelves 31.3 of the third shelf row 40.3. For example, the shelves 31.3 of the third shelf row 40.3 are, on one side, facing the at least one shelf support 37 or 37.1 with one of their transverse sides 34, and preferably, at least one further shelf support 37' or 37.1' is assigned to the shelves 31.3 of the third shelf row 40.3 on their other transverse side 35, which is, for example, located on the outside of the racking system 30.

[0053] The shelving system 30 can be a sliding shelving system. Preferably, the shelves 31.1 and / or shelves 31.2 and / or shelves 31.3 are inclined laterally. For example, the longitudinal side 33 of shelves 31.1, 31.2, or 31.3 facing the rear 5 is higher than the longitudinal side 32 facing the front 4 of the cold storage room 1. This inclination of shelves 31.1, 31.2, or 31.3 allows goods placed on them to slide down, for example, when goods located near the bottom are removed. At least one of shelves 31.1, 31.2, or 31.3 can be extendable. For example, a telescopic rail 38 is arranged on the transverse sides 34, 35 of the at least one shelf.

[0054] The shelves 31.1, 31.2, and 31.3 can each have a plurality of dividers 41. Preferably, the dividers 41 are elongated and extend longitudinally in the direction of the transverse dimension of the shelves 31.1, 31.2, and 31.3, respectively, to form sliding tracks for the goods placed on the shelves 31.1, 31.2, and 31.3. The shelves 31.1, 31.2, and 31.3 can also have a product stop 42 at their lower end to prevent the goods from sliding and thus to hold the sliding goods on the corresponding shelf.

[0055] As from the Figures 1 to 3 As can be seen at least in outline, the cold storage room 1 has a recirculating air system 50, for example, to circulate air inside the cold storage room 1, preferably around the room axis A. This air or recirculated air promotes the cooling of the goods stored in the cold storage room 1. Preferably, the recirculating air system 50 is equipped with a (in the Figures 1 to 3 (not shown) refrigeration generator coupled or connectable in terms of refrigeration technology. Alternatively, the recirculating air system 50 can be equipped with a (in the Figures 1 to 3 (not shown) cold air generators may be fluidically coupled or couplingable.

[0056] Figure 4 Figure 1 shows a perspective view of an area of ​​the cold storage room 1 with the parts of the air circulation system 50 located there, whereby the shelf system 50 and the door elements 12 are omitted for a better understanding of the operation of the air circulation system 50. Figure 5 The recirculation system 50 is shown, as it is in the Figure 4 shown without the cold storage room 1. Figure 6 The image shows the recirculation system 50 in a perspective view from above.

[0057] The recirculating air system 50 comprises a nozzle assembly 52. ​​The nozzle assembly 52 comprises a plurality of nozzle tubes 54. Preferably, the nozzle tubes 54 are arranged distributed along the product presentation side 10 and / or along the front longitudinal side 32 of the shelves 31.1, 31.2, and 31.3, respectively, for example, arranged in a row. Preferably, the nozzle tubes 54 are arranged distributed along the front longitudinal side 32 of the shelves 31.1 of the first shelf row 40.1, and preferably along the front longitudinal side 32 of the shelves 31.1 of the second shelf row 40.2, and preferably along the front longitudinal side 32 of the shelves 31.1 of the third shelf row 40.3, in particular arranged in a row. The nozzle tubes 54 are directed downwards onto the first gap 13.1. Air can be blown in a targeted vertical direction downwards through the nozzle tubes 54, particularly in the direction indicated by arrows 80, as for example from the Figures 3 and 4This is evident. The first space, 13.1, can be used for this purpose.

[0058] Preferably, the nozzle tubes 54 are associated with an air duct 53, preferably an elongated one. Preferably, the air duct 53 extends longitudinally along the shelves 31.1 of the first shelf row 40.1, preferably along the shelves 31.1 of the second shelf row 40.2, and preferably along the shelves 31.1 of the third shelf row 40.3. Preferably, the nozzle tubes 54 are arranged circumferentially on the air duct 52. At least one, some, or all of the nozzle tubes 54 is or are, for example, inserted into a corresponding opening of the air duct 53. A rubber-elastic pipe bushing 55 can be installed between the inserted nozzle tube 54 and the edge of the corresponding opening. Figure 6 ) arranged which on one side rests against the edge of the opening and on the other side clamps around the inserted nozzle tube 54.1.

[0059] Preferably, the air duct 53 and / or the nozzle tubes 54 are arranged in an upper area of ​​the cooling room 1, for example in the area of ​​the ceiling 3.1, preferably near the ceiling. For example, the air duct 53 is mounted on the ceiling 3.1, in particular mounted against the ceiling 3.1. The air duct 53 can have a rectangular cross-sectional contour. Furthermore, at least some of the nozzle tubes 54 can be assigned to the same longitudinal side of the air duct 53 and distributed along its length.
