Description

[0001] The invention relates to a room-like cell for cooling or heating goods.

[0002] A generic room-like unit for cooling or heating is known from US 5,097,673 A. Further room-like units for cooling or heating are known from FR 2,230,150 A5 and FR 2,378,481 A1.

[0003] One object of the invention is to propose a novel concept of a space cell for cooling or heating goods.

[0004] The problem is solved with a space cell that has the features of claim 1. Advantageous embodiments and / or configurations and / or aspects of the invention will become apparent from the dependent claims, the following description and the figures.

[0005] A room cell according to the invention for cooling or heating goods is bounded at the top by a ceiling, at the bottom by a floor, and laterally in one spatial direction by two, for example, opposing side walls. At least one of the side walls is designed as a product display wall and is provided with at least one opening for this purpose.

[0006] The room unit has at least one merchandise display unit, which includes a display side for the goods and is arranged between the side walls such that its display side faces the display wall and is set back from it, creating a first gap. This allows the goods to be removed from the display unit via the opening from the outside, particularly from outside the room unit, and a second gap is formed between the display unit and the other side wall. This second gap may be accessible. An access point may be provided on one of the side walls of the room unit for this purpose.

[0007] In such a modular unit, the goods contained within can be displayed to the outside, i.e., outside the unit, thanks to the opening in at least one side wall. Likewise, goods can be removed through this opening, for example by a customer.

[0008] To close the opening in the side wall or the merchandise display wall, at least one, preferably several, doors or door elements can be provided. The at least one door can be a swing door or a sliding door. To maintain the display function, the doors have at least one area or section that is transparent, in particular, made of clear material. For example, the at least one door is a glass door.

[0009] In this disclosure, the term "room cell" refers in particular to a room that is assembled from individual elements, for example, from individual elements assembled on-site, i.e., in the room where the room cell is installed. The individual elements are, for example, industrially prefabricated. In this disclosure, the term "goods" includes in particular perishable goods and / or foodstuffs.

[0010] The modular unit is suitable, for example, for use in any type of retail space, such as supermarkets or petrol station sales areas. The modular unit is also suitable for cooling or heating goods. In the present disclosure, "cooling" means, in particular, that the goods are cooled to a predetermined temperature and / or kept cool at a predetermined temperature. The predetermined temperature may be such that the goods are subject to deep freezing or can be stored at a deep-freeze temperature. In the present disclosure, "heating" means, in particular, that the goods contained in the modular unit are heated to a predetermined temperature and / or kept warm at a predetermined temperature.

[0011] In such a modular unit, the floor is designed to include at least one floor element covered with an elastomer coating. This gives the floor of the modular unit favorable properties in terms of resistance, flammability, and solvent resistance. The floor of the modular unit also exhibits favorable robustness. All these properties are essentially achieved through the elastomer coating, which forms the contact surface facing the interior of the modular unit, for example, for the merchandise display. Due to these favorable properties, the elastomer coating is suitable for use as a floor covering in modular units used for cooling or heating goods, i.e., maintaining corresponding temperatures within the unit. Furthermore, it is advantageous to place the merchandise display on the at least one floor element.

[0012] In this disclosure, the term "elastomer coating" refers in particular to a coating that comprises or consists of at least one elastomer. In this disclosure, the term "elastomer" refers in particular to a dimensionally stable but elastically deformable plastic. Specifically, this plastic has a glass transition temperature below its service temperature, such that the plastic permanently retains its dimensionally stable but elastically deformable shape.

[0013] The elastomeric coating can contain or consist of rubber. In principle, the elastomeric coating can be made of or comprise any elastomer. In particular, the elastomeric coating is PVC-free.

[0014] The elastomeric flooring may be designed to have a slip-resistant surface. This helps prevent potential injuries if the interior of the room is designed to be accessible and people walk on the floor.

[0015] Such a slip-resistant surface can be designed to meet, or be capable of meeting, the high slip resistance requirements of R11. This can be achieved by incorporating solid particles into the elastomeric coating, for example, by scattering them into the surface to provide slip resistance.

[0016] The solid particles can be made of granite or contain granite. This facilitates achieving a high level of slip resistance. In principle, any type of material is suitable as solid particles, provided the material has sufficient strength.

[0017] The floor element comprises a plate-shaped base body onto which the elastomeric coating is laid, in particular directly. Specifically, the elastomeric coating is bonded to the base body by means of a material bond and / or a form-fit connection, for example, by means of additional connecting elements. For example, the elastomeric coating is glued to the plate-shaped base body. In this way, measures are taken to achieve a stable and highly durable floor covering made of the elastomeric coating.

[0018] Simple and cost-effective manufacturing is facilitated if, after a certain design, the plate-shaped base body is a wooden panel. The wooden panel can be a veneered plywood panel or another type of MultiPLEX panel.

[0019] The base element comprises at least one foot element, which has a standing surface for placement on a substrate and a bearing surface for supporting the base body in order to create at least one ventilation channel between the base body and the substrate. For example, the at least one foot element is attached to the base element.

[0020] In particular, at least two base elements are provided, which are arranged at a distance from each other and on which the base body is placed, and in particular attached, so that a ventilation slot or other ventilation channel exists between the base body and the surface when the base element is placed on the surface. The at least one base element can be a wooden strip.

[0021] According to a further embodiment, the room unit includes a cooling unit or a heating unit, or at least a component thereof. The cooling unit or the heating unit, or the at least one component thereof, can be mounted on the ceiling of the room unit or at least be supported against the ceiling of the room unit. For example, the cooling unit or the heating unit could be a device that generates cold air or warm air.

[0022] According to a further embodiment, the room cell has a recirculating air system comprising at least one blower, at least one, preferably several or a plurality of air outlet openings and at least one air inlet opening, wherein at least some of the air outlet openings are directed towards the first intermediate space in order to blow air into the first intermediate space by means of the air outlet openings.

[0023] It may be provided that at least one air inlet opening is arranged in the area of ​​the second gap and / or in the area of ​​a space occupied by the merchandise presentation device in order to draw in a predetermined amount of air via the second gap and / or via the space occupied by the merchandise presentation device.

[0024] For example, the recirculation system, in particular the air outlet openings and / or the at least one air inlet opening, is arranged in the area of ​​the ceiling, so that air is blown from above into the first intermediate space by means of the air outlet openings and air is drawn in, for example, from above from the second intermediate space and / or from a space occupied by the merchandise presentation device by means of the at least one air inlet opening.

[0025] According to a further embodiment, the room unit is modular and comprises at least two modules, a first module comprising at least one floor element and the merchandise display unit, and a second module comprising another floor element and another merchandise display unit. It is further provided, in particular, that the elastomeric covering of one floor element is connected to the elastomeric covering of the other floor element at their facing edges, and in particular, that it is welded together.

[0026] The room cell can be such a room cell as described in DE 10 2018 108 230.4.

[0027] Additionally or alternatively, the room unit can also be a cold storage room, as described in DE 10 2018 111 346.3.

[0028] Further details and features of the invention will become apparent from the following description of several exemplary embodiments with reference to the drawings. These show Fig. 1 shows a possible embodiment of a floor element for a room unit for cooling or heating goods in a perspective view, Fig. 2 shows a possible embodiment of a room unit for cooling or heating goods in a sectional view, Fig. 3 shows the room unit according to the Figure 2 in a front view, Fig. 4 the room cell according to the Figure 2 In a further sectional view, Fig. 5 shows another possible embodiment of a room cell for cooling or heating goods; in a sectional view, Fig. 6 shows another possible embodiment of a room cell for cooling or heating goods; in a sectional view, Fig. 7 shows another possible embodiment of a room cell for cooling or heating goods; and Fig. 8 shows the cooling cell according to the Figure 7in another sectional view.

[0029] Figure 1 Figure 1 shows – in a schematic representation – a possible embodiment of a floor element 100, suitable for use in a room unit for cooling or heating goods, in a perspective view. The floor element 100 has a top surface 110, which, when installed in the room unit, faces the interior of the room unit. The floor element 100 also has a bottom surface 120, which faces a substrate on which the floor element 100 can be placed.

[0030] The floor element 100 has an elastomeric coating 130 on its upper surface 110, which, for example, comprises or consists of rubber. Preferably, the elastomeric coating 130 has a tread surface 140 that is slip-resistant. For this purpose, the elastomeric coating 130 may contain solid particles that are embedded in the tread surface or surface of the elastomeric coating 130, in particular firmly embedded, thus creating, for example, a certain surface roughness. Granite grains or granite particles can be used as solid particles.

[0031] The base element 100 has a plate-shaped base body 150 on which the elastomer coating 130 is attached, for example, by a material bond and / or a form-fit bond. Preferably, the elastomer coating 130 is bonded to the base body 150. For example, the base body 150 is rectangular or square. In principle, the surface of the plate-shaped base body 150 can have any shape, in particular angular or round.

[0032] The base element 100 has at least one, preferably two, foot elements 160, which are spaced apart from each other and each has a base for placement on a surface. The foot elements 160 are attached to the underside of the plate-shaped base body 150, so that when the base element 100 is placed on a surface, for example, a room for the modular unit, a gap exists between the two foot elements 160 and between the surface and the base body 150. This gap promotes ventilation of the base element 100.

[0033] The base element 100 can be used in various embodiments of a room module. Several such room modules, each utilizing the base element 100, are described below as examples. In the following embodiments, the room modules are referred to as cold storage rooms, which serve to cool goods. These cold storage rooms can also be used to heat or keep goods warm. Therefore, the term "cold storage room" also encompasses a room module used for cooling or heating goods.

[0034] Figures 2 , 3 and 4 The figures show – in schematic representation – a possible embodiment of a cold storage room or a room cell 1. Figure 2 shows a cross-section of cold storage room 1. Figure 3 shows cold storage room 1 in a front view. Figure 4 shows cold storage room 1 in a top view as a partial section.

[0035] The cold storage room 1 is bounded at the top by a ceiling 2, which is located in the Figures 2 and 3 However, this is evident in the partial section of the Figure 4 The cold storage room 1 is furthermore bounded downwards by a floor 3 and laterally in one spatial direction by two, preferably opposing, side walls 4, 5.

[0036] The floor comprises the floor element 100 described above. Preferably, the floor 3 is modularly constructed, so that, for example, three modules, each containing the floor element 100, are provided.

[0037] At least one of the side walls 4, 5, for example side wall 4, is designed as a merchandise presentation wall 8 and has at least one passage opening 9 for this purpose.

[0038] The cold storage room 1 has inside at least one product display unit 20 for receiving chilled goods, which in particular comprises a front 24 and a rear 25, preferably opposite the front 24. The product display unit 20 has a product display side 21 for presenting the chilled goods, which is, for example, associated with or formed by the front 24.The merchandise display unit 20 is arranged between the side walls 4 and 5 such that, on the one hand, the merchandise display unit 20, with its merchandise display side 21, faces the merchandise display wall 8 and is spaced from it, forming a first gap 30, so that the refrigerated goods in the merchandise display unit 20 can be removed from the outside via the opening 9, and on the other hand, a second gap 40 is formed between the merchandise display unit 20 and the other side wall 5. The second gap 40 can be dimensioned such that it is accessible to at least one person. For example, the merchandise display unit 20, with its merchandise display side 21, is arranged essentially parallel to the merchandise display wall 8.

[0039] As can be seen in particular from the Figure 2As can be seen, the merchandise display unit 20 can be a shelf or shelving system and have several compartments arranged vertically one above the other, at least one of which is continuous, i.e., forms a passageway extending from the merchandise display side 21 to the rear 25 of the merchandise display unit 20. For example, each compartment has a shelf 20.1 or other support for holding the refrigerated goods. The shelves 20.1 are attached to or supported by shelf uprights 20.2, in particular vertical uprights. Preferably, the shelf uprights 20.2 rest with their lower end on the floor 3 and extend with their upper end into the upper area of ​​the refrigerated compartment 1, preferably to or against the ceiling. 2.Preferably, the shelf supports 20.2 are dimensioned such that they serve as a supporting structure for the ceiling 2, so that at least in the area of ​​the merchandise presentation equipment 20 a separate supporting structure for the cold room 1 can be dispensed with.

[0040] For example, the merchandise presentation unit 20, designed as a shelf or shelving system, is a sliding shelf or sliding shelf system, as shown in the Figure 2 This is evident. Preferably, the shelves 20.1 are inclined diagonally downwards towards the product presentation side 21 in order to cause or at least promote the sliding of the refrigerated goods on the respective shelf 20.1.

[0041] The refrigerated compartment 1 is particularly suitable for use in a sales area, for example, in a supermarket. The refrigerated goods stored in the display unit 20 are presented to the outside, for example, towards customers, and can be removed by customers as needed through the access opening 9 from the display unit 20 without having to enter the refrigerated compartment 1. The display unit 20 can also be accessed via the second intermediate space 40. This requires entering the refrigerated compartment 1 or walking through the second intermediate space 40. The display unit 20 can be accessed from the rear, for example, from the back 25, via the second intermediate space 40. The display unit 20 can thus be restocked from the rear via the second intermediate space 40.Preferably, the second space 40 is dimensioned such that a person can easily enter and that the merchandise display unit 20 can be accessed from the rear with a certain volume of refrigerated goods in order to fill or refill the merchandise display unit 20.

[0042] The second intermediate space 40 can be accessed through at least one, preferably two, passage openings 67, 68, wherein the passage openings 67 and 68 are preferably provided on side walls 6, 7, which lie between the side walls 4, 5 and together with the side walls 4, 5 form the lateral outer perimeter of the cooling chamber 1. A door 80 or a door element can be provided for closing the passage opening 67. A door 81 or a door element can also be provided for closing the passage opening 68.

[0043] At least one, preferably several, doors 82 or door elements can also be provided to close the passage opening 9 in the side wall 4 or merchandise display wall 8. To maintain the display function, the doors 82 have at least one area or section that is transparent, in particular clear. For example, the at least one door 82 is a glass door.

[0044] As can be seen particularly from the Figures 2 and 4 As can be seen, the side wall 5 can also be designed as a product presentation wall 10 and may have at least one passage opening 11 for this purpose. Furthermore, the cold storage room 1 may have an additional product presentation device 22 for holding refrigerated goods, which includes a product presentation side 23 for displaying the refrigerated goods held therein. The additional product presentation device 22 is located in the Figure 4 indicated by dashed lines.

[0045] For example, the additional product presentation device 22 is arranged between the side walls 4, 5 such that the additional product presentation device 22 faces the product presentation wall 10 with its product presentation side 23 and is spaced away from it by forming a further first gap 31, so that the refrigerated goods of the additional product presentation device 22 can be removed from the outside via the passage opening 11 and the second gap 40 exists between the product presentation device 20 and the additional product presentation device 22.

[0046] The additional merchandise display unit 22 can be structurally and / or functionally identical to the merchandise display unit 20. For example, the additional merchandise display unit 22 has shelves 22.1 and shelf supports 22.2. At least one, preferably several, doors 83 or door elements can also be provided in the side wall 5 to close the passage opening 11. The at least one door 83 can be functionally or structurally identical to the door 82 for the passage opening 9 of the side wall 4.

[0047] Preferably, the cold storage room 1 uses at least one air circulation system 50 to cool the goods stored in the cold storage room 1. Preferably, the air circulation system 50 comprises at least one, preferably several or a plurality of, air outlet openings 52 and at least one air inlet opening 53. Preferably, the air outlet openings 52, in particular at least one or several, or at least a plurality of, the air outlet openings 52, are directed towards the first space 30 between the product display wall 8 and the product display side 21 of the product display device 20, in order to blow air, for example, cold air or cooled air, into the first space 30 by means of the air outlet openings 52. Preferably, the at least one air inlet opening 53 is arranged in the area of ​​the second space 40, in order to draw in air via the second space 40.In principle, at least one air inlet opening 53 can also be located in the area of ​​a space occupied by the merchandise presentation device 20 or extend to it.

[0048] At least one blower 51 is provided for blowing air in through the air outlet openings 52 and / or for drawing air in through the at least one air inlet opening 53. Preferably, the blower 51 is continuously or steppedly adjustable or controllable by means of a control and / or regulating device (not shown in the figures), for example, with regard to its speed.

[0049] The arrangement of the air outlet openings 52 and the at least one air inlet opening 53 creates a controlled recirculation of air, which can be used to circulate around the merchandise display unit 20 and / or to circulate through the compartments of the merchandise display unit 20, depending on how the recirculation flow is adjusted by means of the air outlet openings 52 and / or the at least one air inlet opening 53 and / or the at least one fan 51. is. The recirculated airflow generated by the air outlet openings 52 and the at least one air inlet opening 53 is in the Figure 2 This is exemplified by arrows 90. Regarding the recirculation system 50, the first intermediate space 30 and the second intermediate space 40 each serve as a flow-through space. Therefore, the first intermediate space 30 and the second intermediate space 40 are designed to contribute to achieving the desired recirculation of air.

[0050] For example, the air outlet openings 52 are arranged in a row 70 one behind the other, as can be seen in particular from the Figure 4 This is evident. For example, the air outlet openings 52 are distributed along the merchandise presentation side 21 of the merchandise presentation device 20 and / or along the side wall 4 serving as the merchandise presentation wall 8, preferably in the direction from the side wall 6 to the side wall 7. Preferably, the air outlet openings 52 are arranged in an upper area of ​​the cold storage room 1, for example in an area of ​​the upper third of the cold storage room 1, in particular in the area of ​​or near the ceiling 2 ( Figures 2 and 3 Preferably, the air is blown out from top to bottom via the air outlet openings 52, as shown, for example, by arrows 90 in the Figure 2This is evident. Preferably, at least one air inlet opening 53 is arranged in an upper area of ​​the cold storage room 1, for example in an area of ​​the upper third of the cold storage room 1, in particular in the area of ​​or near the ceiling 2 ( Figures 2 and 3 ).

[0051] Preferably, the air outlet openings 52 are assigned to, and in particular arranged on, a common air duct 54 or supply air duct. In the Figure 4 For better understanding, the air duct 54 is shown in a cross-sectional view, so that the lower air outlet openings 52 of the air duct 54 are visible. At least one of the air outlet openings 52 can be formed by a flow outlet 56 of a nozzle tube 58 flow-connected to the air duct 54, as exemplified by the Figures 2 and 3The air duct 54 can be formed by a pipe, in particular a plastic pipe, which has a round, especially circular, cross-section. For example, the air duct 54 runs essentially straight or in a straight line in the area along the side wall 4, which serves as a product presentation wall 8. Preferably, the air inlet opening 53 is assigned to, and in particular arranged on, a separate air duct 55 or exhaust duct.

[0052] For example, the blower 51 is associated with the air duct 55, and in particular is arranged within it. The air ducts 54 and 55 can be flow-connected to each other, for example via an intermediate chamber, so that the recirculation system 50 allows for the circulation of the air within the cooling chamber 1. Preferably, the air duct 54 and / or the air duct 55 is closed in cross-section at one longitudinal end 75 and preferably open in cross-section at the other longitudinal end 76, so that an airflow can be directed through the air outlet openings 52 or the at least one air inlet opening 53 provided therein and through the open end 75 in the air duct 54 or 55.

[0053] The air duct 54 and / or the air duct 55 can be modular. For example, the air duct 54 can be formed from several detachably connected duct sections 62, 63, 64, as shown in the Figure 4As indicated, at least one of the duct sections 62, 63, 64, for example, duct sections 63, 64, can have some or all of the air outlet openings 52. Preferably, the duct sections 62, 63, 64 are each designed as plug-in elements, for example, each duct section 62, 63, 64 having a plug-in receptacle at one end and a plug-in section at the other end for insertion into the plug-in receptacle. Preferably, the air duct 54 or the duct sections 62, 63, 64 are formed by pipe sections. Preferably, the duct section 62 is a pipe bend.

[0054] The recirculating air system 50 can be flow-connected to a heat exchanger 65, for example, a heat exchanger, through which heat is extracted from an outside air stream and / or the air stream drawn in via the air inlet opening 53 and supplied to the air outlet openings 52 as a cold air stream or cooled air stream. Preferably, the heat exchanger 65 is flow-connected to the air duct 54 on the outlet side, in particular via the open end 76 of the air duct 54, and, for example, flow-connected to the air duct 55 on the inlet side, in particular via the open end 76 of the air duct 55. Preferably, the heat exchanger 65 is arranged outside the cooling chamber 1.

[0055] Preferably, the heat exchanger 65 is a component of a cooling unit 66, which includes a refrigeration unit that is coupled to the heat exchanger 65, for example, via a refrigerant-carrying circuit system, in order to extract heat from the air flowing past or through the heat exchanger 65. The cooling unit 66 thus generates cold air at its outlet, which is supplied to the cooling room 1 as cold air or cooled air via the air duct 54 and the air outlet openings 52.

[0056] Preferably, the cooling unit 66 is arranged on the roof or ceiling 2 of the cold storage room 1 or at least supported against the ceiling 2 of the cold storage room 1. The heat exchanger 65 can be a component of the cooling unit 66 and, for example, be arranged outside the cold storage room 1. For example, the heat exchanger 65 is arranged in a housing of the cooling unit 66, which is located outside the cold storage room 1 and, for example, projects into the cold storage room 1 via a through-opening, for example, in the ceiling 2 of the cold storage room 1, with its inlet and outlet. Preferably, the outlet is connected to the air duct 54. Preferably, the inlet is connected to the air duct 55.

[0057] If the merchandise display unit 22 is provided, the recirculation system 50 can be extended such that the merchandise display unit 22 is also subjected to the recirculation air movement and / or a separate recirculation air movement by the recirculation system 50. Preferably, further air outlet openings 52' are provided for this purpose, which are directed towards the further first intermediate space 31 between the merchandise display wall 10 and the merchandise display side 23 of the merchandise display unit 22, in order to blow air into the further first intermediate space 31 by means of the air outlet openings 52'. This creates a recirculation air movement which flows around and / or through the merchandise display unit 22, depending on how the air outlet openings 52' are arranged and dimensioned.

[0058] The airflow supplied via the air outlet openings 52' into the further first intermediate space 31, after flowing around and / or through the merchandise display device 22, enters the second intermediate space 40 and is then, for example, together with the airflow that has flowed around and / or through the merchandise display device 20, at least partially discharged via the at least one air inlet opening 53. The recirculated airflow generated by the air outlet openings 52' and the at least one air inlet opening 53 is in the Figure 2The air outlet openings 52' are indicated by way of example by arrows 90'.

In this way, the air drawn in from the interior of the cooling chamber 1.1 via the air inlet openings 73' is conveyed in the air duct 73 towards its open end and then flows into the cooling unit 66, where the air is cooled down to a predetermined temperature and then returned to the interior of the cooling chamber 1.1 as cooled air via the air duct 54 and the air outlet openings 52.

[0064] Preferably, the air duct 73 with the air inlet openings 53' is arranged inside the cooling chamber 1.1, for example at approximately the same height as the air duct 54 with the air outlet openings 52. Preferably, in this case, the air inlet openings 53' point downwards, i.e., they are located in the downward-facing section of the casing of the air duct 73. Figure 5For better understanding, the air duct 73 is shown in a sectional view, so that the lower air inlet openings 53' of the air duct 73 are visible.

[0065] Preferably, the air duct 73 is modularly composed and has at least two detachably connected duct sections 74, which are mechanically connected to each other, for example, by means of plug connections. For example, the air duct 73 is equipped or constructed in the same way as the air duct 54, wherein the air outlet openings 52 with optionally the nozzle tubes 58 are provided in the air duct 54 and the air inlet openings 53' are provided as through-openings in the air duct 73.

[0066] Preferably, the further intended recirculation system 50' is also designed in the same way as the recirculation system 50 with regard to the air inlet openings 53'. In this respect, reference is made to the preceding descriptions regarding the several intended air inlet openings 53'.

[0067] Air circulation along the length of the cooling chamber 1.1, i.e., in the direction from side wall 6 to side wall 7, is achieved by the air duct 54, which serves as the supply air duct, and the air duct 73, which serves as the exhaust air duct. This results from the fact that the supply air duct 54(s) and the exhaust air duct 73 extend along the longitudinal direction of the cooling chamber 1.1, thus creating a circulation transverse to the longitudinal direction of the cooling chamber 1.1, which is preferably maintained uniformly along the longitudinal direction of the cooling chamber 1.1.

[0068] Figure 6 Figure 1 shows another possible embodiment of a cold storage room or a room cell 1.2 in cross-section. Components of the cold storage room 1.2 of the Figure 6 , which are identical or functionally equivalent to components of cold storage room 1 of the Figures 2 to 4 are marked with the same reference symbols; therefore, reference is made to the description of cold storage room 1 of the Figures 2 to 4 referred.

[0069] The cold storage room 1.2 of the Figure 6 differs from cold storage room 1 of the Figures 2 to 4This is because the product display wall 10 of cold storage room 1 is not provided in cold storage room 1.2. Instead, a side wall 5' is provided there, which has no opening through it. The side wall 5' has a closed wall surface 29, which is, for example, completely closed. Instead of the product display unit 22 of cold storage room 1, a storage unit 26 can be provided in cold storage room 1.2, with a front 27 and a back 28, whereby at least the front 27 can be used as a filling side.

[0070] The storage device 26 is arranged between the side walls 4, 5' such that its rear side 28 faces the side wall 5' and is spaced apart from it, forming a further first gap 31, with a second gap 40 between the storage device 26 and the product presentation device 20. The cold storage room 1.2 is also – like the cold storage room 1 already described – Figures 2 to 4 - accessible. Therefore, the second intermediate space 40 can be entered by at least one person.

[0071] In cold storage room 1.2, the product display unit 20 allows for both external product presentation and product removal from outside the cold storage room. Additionally, the storage unit 26 within cold storage room 1.2 enables the temporary storage of goods that are simultaneously cooled or kept cool by the cold storage room 1.2. The goods stored in the storage unit 26 can be used to replenish or restock the product display unit 20.

[0072] In principle, the same applies to cold storage room 1.2 as to cold storage room 1.1. Figure 5 The described design of the air duct or exhaust duct 73 is to be implemented. Regarding the design in the cold storage room 1.2, the identical design according to cold storage room 1.1 can be applied. Figure 5 Reference is made to the device which can be used in the same way in cold storage room 1.2.

[0073] After another (in the Figure 6 In the embodiment not shown, the cold storage room 1.2 can also be provided without the storage device 26. In this case, for example, the area where the storage device 26 would be provided allows for the stacking of goods to be stored. For example, beverage crates or other stackable boxes or packaging can be stacked in this area, which are also surrounded by cold air or cooled air in this area by means of the recirculating air system 50.

[0074] Figures 7 and 8 Figure 1.3 shows a further embodiment of a cold storage room or a room cell. Figure 7 The diagram shows a cross-section of cold storage room 1.3. Figure 8 The diagram shows a top-down view of cold storage room 1.3 as a partial section, with the ceiling omitted. Components of cold storage room 1.3 of the Figures 7 and 8 , which are connected to components of cold storage room 1 of the Figures 2 to 4 or the cold storage room 1.1 of the Figure 5or of the cold storage room 1.2 of the Figure 6 Items that are identical or functionally equivalent are marked with the same reference numerals; in this respect, reference is made to the description of cold storage room 1, cold storage room 1.1, or cold storage room 1.2.

[0075] Cold storage room 1.3 differs from cold storage room 1 of the Figures 2 to 4 because the cold storage room 1.3 has only the product display wall 8 as its sole product display wall. Therefore, the passage opening 9 for removing and / or displaying goods from the product display unit 20 is only provided in the side wall 4. The side wall at the rear of the cold storage room 1.3 is marked with the reference numeral 5', as this side wall 5' is completely closed, i.e., it has the closed wall surface 29, as already described for the refrigerated display case 1.2. Figure 6 is described.

[0076] Unlike refrigerated display case 1 of the Figures 2 to 4 Is cold storage room 1.3 the Figures 7 and 8The cold storage room 1.3 is designed to be particularly compact and therefore not accessible. Accordingly, the opposing side walls 6' and 7' are provided without an access opening to the interior of the cold storage room 1.3. Openings may be provided in the side walls 6' and 7' to allow lateral access to the product display unit 20 or the flow-through chamber, or to the second intermediate space 40 and the first intermediate space 30. However, the second intermediate space 40 is relatively compact and not accessible. Preferably, in the cold storage room 1.3, the second intermediate space 40 borders directly on the side wall 5'.

[0077] As already mentioned in cold storage room 1.1 of the Figure 5 For example, the exhaust air duct 73, which has a multitude of air inlet openings 53', is also provided in cold room 1.3. The modularity of the air duct 73 can be, as already in cold room 1.1, Figure 5 as described, also present in cold storage room 1.3.

[0078] In the present disclosure, the term "chilled goods" is understood to mean, in particular, goods requiring refrigeration, such as foodstuffs, especially perishable foodstuffs. For example, a refrigeration temperature of approximately 6 degrees Celsius or approximately 3 degrees Celsius or less must be maintained. This also includes frozen goods, which, for example, must be kept refrigerated at a temperature of at least -12 degrees Celsius or at least -20 degrees Celsius. The refrigeration capacity of the cold storage room is, or can be, dimensioned accordingly. Reference number list
