The carrier structure shown comprises a first section 110 arranged vertically according to the illustration and a second section 120 arranged horizontally according to the illustration, which is substantially perpendicular to the first section 110. The left side of the first section (not visible in FIG. 2 a) as shown is referred to as outer side 112, and the right side of the first section 110 as shown is referred to as inner side 114. The upper side of the second section 120 as shown is referred to as the outer side 122, while the lower side of the second section 120 as shown (not visible in FIG. 2 a) is referred to as the inner side 124.As shown in FIG. 2a, the sections 110 and 120 can be designed as separate components which are firmly connected to one another. Alternatively, however, the sections 110 and 120 can also be only sections of a single structural component. Furthermore, the sections 110 and 120 can be embodied as solid material construction as illustrated. Alternatively, one or both sections can be designed as a cavity construction, as shown in FIG. 2b. The construction of the support structure in a hollow construction can allow a better connection, for example if the sections 110 and 120 are designed as separate components, due to the greater contact surface of the two components. In addition, by filling the cavity 116 of the portion 110 and / or the cavity 126 of the portion 120 with a material of low thermal and / or acoustic conductivity, an improved thermal and / or acoustic insulation of the support structure can be achieved.FIG. 2 cshows the support structure 100 from FIG. 2 a, wherein the extension of the support structure 100 in the direction of the dashed line B-B is referred to as the width of the support structure or of the roller shutter / venetian blind, the extension in the direction of the dashed line H-H is referred to as height and the extension in the direction of the dashed line T-T is referred to as depth. In addition, the right-hand side of the support structure as viewed in the illustration in the direction of the dashed line T-T is referred to as the front side of the support structure or of the roller shutter / refinery drawer, the left-hand side as viewed in the illustration (not visible in FIG. 2 c ) is referred to as the rear side. Furthermore, the side of the support structure facing the observer as shown in the illustration is referred to as the left side of the support structure or of the roller shutter / venetian blind in the direction of the dashed line B-B, and the side facing away from the observer as shown (not visible in FIG. 2 c ) is referred to as the right side in the direction of the dashed line B-B.FIG. 2 d shows the carrier structure 100 from FIG. 2 a together with a third section 130 arranged on the front side of the carrier structure 100, wherein the right side according to the illustration is referred to as the outer side 132, the left side according to the illustration (not visible in FIG. 2 d ) is referred to as the inner side 134. The third section can be designed as a separate component, as shown in FIG. 2d. Alternatively, the third section 130 can be designed with the second section 120 as a structural component. The third portion 130 may have a function of a shutter. The third portion 130 may have a supporting function. The third portion 130 may have the function of an air-guiding member. The height of the third portion 130 (i.e. the extension thereof in the direction of the dashed line H-H from FIG. 2 c ) can be less than the height of the carrier structure 100, as illustrated in FIG. 2 d. In other embodiments, the third portion 130 may be extended downward as long as or longer than the first portion 110 in the height direction. The third section 130, which is shown in FIG. 2 d as being embodied as a solid material construction, can also be embodied as a hollow construction, just like the sections 110 and 120.FIG. 2 e shows the carrier structure 100 together with the third section 130 from FIG. 2 d, and a lateral end piece 140 amounted on the left side of the carrier structure 100. FIG. 2 f shows the carrier structure 100 together with the third section 130 from FIG. 2 d and a lateral end piece 140 bmounted on the right side of the carrier structure. The lateral end pieces 140 aand 140 billustrated in a solid material construction can also be designed in a hollow construction, like the sections 110, 120 and 130.The support structure 100, the third portion 130, and the side end pieces 140 aand 140 bmay be combined as desired. The sections and elements designated by the reference numerals 110, 120, 130, 140 aand 140 bmay be embodied in any desired combinations in a solid material construction and / or a hollow material construction. Further, any combinations of two or more of the portions and members denoted by reference numerals 110, 120, 130, 140a, and 140b may be configured as a unitary component.FIG. 3 ashows a perspective view of the first molded part module 200. This comprises a curved shaped part 210 and a base structure 220, which are firmly connected to one another. The base structure 220 in turn comprises a left-hand section 222 as shown, a right-hand section 224 as shown and a lower section 226 as shown. The sections 222, 224 and 226 form a cavity 230 together with the curved mold part 210.FIG. 3 bshows the first molded part module 200 from FIG. 3 a, wherein the extent of the first molded part module 200 in the direction of the dashed line B-B is referred to as the width of the molded part module, the extent in the direction of the dashed line H-H is referred to as the height, and the extent in the direction of the dashed line T-T is referred to as the depth. The width, height, and depth directions with respect to the first molding module 200 may match the width, height, and depth directions with respect to the support structure 100, and the roller shutter / venetian blind box, respectively, as shown in FIG. 2 c; in other embodiments, this may be different.FIG. 3 cshows a perspective view of the curved shaped part 210 from FIG. 2 a. The curvature r of the shaped part is adapted to the curvature of a roller shutter armour in the fully retracted state, so that the distance between the shaped part 210 and the roller shutter armour in the fully retracted state is as small as possible. A shape of the molded part 210 that is optimally matched to the shape of the roller shutter armour in the fully retracted state can have various advantages compared to roller shutter boxes whose inner life is composed of a plurality of sections that are exclusively non-curved: the improved utilization of space when using an optimally curved molded part can enable more insulating material to be introduced into the cavity 230, as a result of which improved thermal insulation can be achieved. Minimizing the air-filled space between the molded part 210 and the roller shutter armour can, additionally or alternatively, provide for improved sound attenuation. The curvature of the molding 210 may provide for improved air circulation.In some embodiments, the molded part 210 is made of wood fiber boards, which in turn are made of lignocellulosic fibers. Lignocellulose forms the cell walls of wood-treated plant parts and can be obtained as renewable raw material, inter alia, from wood, wood waste, saw by-products, but also from wood fiber-containing plants such as straw, reed, flax or oilseed rape.At the molecular level, lignocellulose consists essentially of cellulose and hemicelluloses, which, because of their fibrous structure, are each characterized by a high tensile strength, as well as lignin, which, as a natural polymer with thermoplastic properties under normal environmental conditions, has a high rigidity and compressive strength and, to a certain extent, functions as a natural adhesive between the cellulose fibers.In order to impart its curvature to a molded part 210 made of a wood fiber board, the molded part is first heated under the action of water vapor. Due to the properties of lignin as thermoplastic, the stiffness of the latter is reduced by the heating, whereby the previously dimensionally stable wood fiber board becomes deformable. By means of manual or machine forming methods, the wood fibre board made deformable is drawn, bent, pressed and / or pressed into the desired shape by the action of tensile and / or compressive forces. The cooling and drying of the shaped part increases the rigidity of the lignin, which is temporarily reduced by heating, whereby the shaped part retains its curvature imparted to it. In order to avoid undesirable deformations of the molded part during the drying process, suitable devices for shape retention are required.In other embodiments, the molded part 210 is not produced by forming methods, but by separating methods such as sawing, planing, milling or drilling.FIG. 3 d shows a perspective view of the base structure 220 from FIG. 3 a. In addition to portions 222, 224 and 226, base structure 220 may also include other elements such as width-wise oriented support structure 240 and / or depth-wise oriented support structure 250, which in turn may include one or more width support elements 242 and / or one or more depth support elements 252, 254. In the case of the presence of the support structures 240 and / or 250, the cavity 230 may be divided into a plurality of smaller cavities. In the case of a broader first molded part module 200, the supporting structures 240 and / or 250 can contribute to a higher dimensional stability of the molded part module and to the improved connection between the molded part 210 and the base structure 220.FIG. 4 ashows a perspective view of the carrier structure 100 together with a first molded part module 200 which is arranged on the inner side 114 of the first section 110, preferably flush, with the lower edge thereof.FIG. 4 bshows a perspective view of the carrier structure 100 together with a first molding module 200 which is arranged as in FIG. 4 a, and additionally a second molding module 300 which has been rotated by 180° about an axis running in the depth direction of the molding module compared to the first molding module 200, such that it is arranged on the inner side 114 of the first section and at the same time on the inner side 124 of the second section. Due to the arrangement of the second molded part module 300, this can additionally improve the connection thereof, for example if the sections 110 and 120 are designed as separate components. The molding modules 200 and 300 may have a distance d 1 along the inner side 114 of the first portion in the height direction.FIG. 4 cshows a perspective view of the carrier structure 100 together with the third section 130 together with a first molded part module 200, a second molded part module 300 and additionally a third molded part module 400. The molded part modules 200 and 300 are arranged as in FIG. 3 b and can have a distance d 1 along the inner side 114 of the first section in the height direction. The third molded part module 400 is rotated by 180° about an axis running in the width direction of the molded part module, compared to the first molded part module 200, so that it is arranged on the inner side 124 of the second section 120 and at the same time on the inner side 134 of the third section 130. The mold part modules 300 and 400 may have a distance d 2 along the inner side 124 of the second section in the depth direction.FIG. 5 ashows a perspective view of the support structure 100 together with a chamber system module 500 arranged vertically according to the illustration. The chamber system module 500 can consist of one or more chamber elements 510, 520, which, according to the illustration, are arranged one behind the other in the depth direction flush on the rear side 112 of the carrier structure 100 and are firmly connected to the latter and to one another. The extent of the individual chamber elements in the depth direction can be the same for all chamber elements, as shown in FIG. 5a. In other embodiments, as illustrated for example in FIGS. 1 aand 1 b, the individual chamber elements can have different extensions in pairs in the depth direction. The combination of one or more chamber elements with different expansions in the depth direction allows the expansion of the entire roller shutter / refinery crate in the depth direction to be individually adapted to the respective circumstances. This includes, in particular, but not exclusively, the adaptation to standard wall thicknesses of 220 mm, 240 mm, 250 mm, 260 mm, 280 mm, 300 mm, 365 mm, 425 mm, and 490 mm.FIG. 5 bshows a perspective view of the support structure 100 together with the chamber system module 500 from FIG. 5 a, which is composed of two chamber elements 510 and 520 according to the illustration, and with an additional chamber system module 600 arranged horizontally according to the illustration. The chamber system module 600 can consist of one or more chamber elements 610, 620, which are arranged above one another in the height direction according to the illustration flush on the upper side 122 of the carrier structure 100 and are firmly connected to the latter and to one another. The extension of the individual chamber elements in the height direction can be the same for all chamber elements, as shown in FIG. 5 b. In other embodiments, as illustrated for example in FIGS. 1 aand 1 b, the individual chamber elements can have different expansions in the height direction, preferably in pairs. The combination of one or more chamber elements with different expansions in the height direction allows the expansion of the entire roller shutter / venetian blind box in the height direction to be individually adapted to the respective circumstances.Individual cavities, a plurality or all cavities existing within the molded part modules and within the chamber elements of the chamber system modules can be completely or partially filled with insulating materials which have a low thermal and / or acoustic conductivity. In addition to conventional mineral-based insulating materials such as perlite (as bulk material), mineral wool (as mats or sheets), expanded clay (as bulk material) and foam glass (as bulk material or sheet), insulating materials which consist wholly or partly of renewable raw materials can also be used.Typical insulation materials can comprise in this connection the following materials and material classes: sisal (as mats or boards), kenaf (as mats or boards), (burning) nettle fibers, animal hair, fungal mycelium (as insulation boards), cellulose-textile fiber hybrid dams made of cellulose (waste paper) and textile fibers (waste clothes), hemp (as stuffing or blow-in insulation), straw (as boards or blow-in insulation), flax (as mats or boards), sheep wool (as mats or stuffing), wood fiber / wood chips / wood wool (as mats, boards, stuffing, blow-in insulation or as bulk insulation), cellulose (as boards or blow-in insulation), Coconut fiber (as mats or boards), reed / tube bulb (as mats, boards, stuffing, blow-in insulation or as bulk insulation), sea grass (as mats, boards, stuffing, blow-in insulation or bulk insulation), cork (as mats, boards, stuffing, blow-in insulation or bulk insulation), jute (as mats, boards, stuffing, blow-in insulation or bulk insulation), meadow grass cellulose insulation (as blow-in insulation or bulk insulation).All explanations apply to roller shutter and refinery boxes which are designed as new construction, add-on or front-end boxes.FIG. 6 shows a perspective view of a wall leadthrough element 1100, which can be provided for a ventilation device 1000, for example in the form of decentralized room ventilation. The wall passage element 1100 can be designed as a rectangular parallelepiped element.The wall feedthrough element 1100 has a first side 1101 and a second side 1102. In the installed state, the first side 1101 will usually represent the rear side which points toward the interior of the building and the second side 1102 the front side which points toward the exterior of the building and toward the outside, respectively.The wall feedthrough element 1100 has a third side 1103 and a fourth side 1104. In the installed state, the third side 1103 will usually represent the underside, which points downwards or "bottom", and the four side 1104 the upper side, which points upwards or "sky".The wall feedthrough element 1100 has a fifth side 1105 and a sixth side 1106. In the installed state, when looking from the outside onto a building wall which is arranged the wall passage element 1100, the fifth side 1105 will usually represent the right side and the sixth side 1106 will represent the left side.According to the representations, the wall passage element 1100 is shown by way of example as a cuboid element. In such an embodiment, the first, second, third, fourth, fifth and sixth sides of the wall feedthrough element 1100 substantially correspond to the surfaces of the cuboid. In other words, the sides opposite each other are substantially parallel to each other, whereas mutually adjoining sides are substantially perpendicular to each other.However, embodiments are also provided in which mutually opposite surfaces are not substantially parallel to one another and / or mutually adjacent surfaces are not perpendicular to one another. In such embodiments, the wall feedthrough element 1100 may have, for example, the shape of a parallelepiped, or more generally the shape of a polyhedron with six sides.The first and second sides 1101 and 1102 are parallel to each other as opposite sides of the wall passage member 1100. In some embodiments, sides 1101 and 1102 may also be only approximately parallel. In some embodiments, sides 1101 and 1102 may have a surface structure. The perpendicular to the first side 1101 of the wall feedthrough element 1100 defines a depth direction of the wall feedthrough element 1100, which is illustrated in FIG. 7 by a dashed line and is denoted by T Q- T Q( "depth direction cuboid element").The sides 1103 and 1104 are parallel to each other as opposite sides of the wall passage member 1100. In some embodiments, sides 1103 and 1104 may be only approximately parallel. In some embodiments, the sides 1103 and 1104 may have a surface structure. The perpendicular to the third side 1103 of the wall feedthrough element 1100 defines a height direction of the wall feedthrough element 1100, which is illustrated in FIG. 7 by a dashed line and is denoted by H Q- H Q( "height direction cuboid element").The sides 1105 and 1106 are perpendicular, as mutually opposite sides of the wall leadthrough element 1100, to the mutually likewise opposite sides 1101 and 1102 of the wall leadthrough element 1100. The direction perpendicular to both the depth direction T Q- T Q and the height direction H Q- H Q defines a width direction of the wall passage member 1100, which is indicated by a broken line in FIG. 7 as B Q- B Q( "rectangular parallelepiped width direction").The side of the wall leadthrough element 1100 perpendicular to the width direction B Q- B Q whose distance from the passage 1110 is smaller than to the carrier recess 1120, is referred to as the side of the wall leadthrough element 1100 close to the passage and is the right side 1105 of the wall leadthrough element 1100 according to the illustration in FIG. 8. The side of the wall leadthrough element 1100 opposite the side close to the passage is referred to as the side of the wall leadthrough element 1100 remote from the passage and is the left side 1106 (not visible in FIG. 8 ) of the wall leadthrough element 1100 according to the illustration in FIG. 8.The wall passage element 1100 has an air passage 1110 (also referred to as passage for short hereinafter) which extends from the first side 1101, which is at the rear as shown, to the second side 1102, which is at the front as shown. The air passage 1110 is configured to be able to pass air through the wall passage member 1100, in particular, to provide air to the outside and reverse from a building interior. The air passage 1110 has an inlet / outlet port 1110 aon the first side 1101 and an inlet / outlet port 1110 bon the second side 1102. Whether the openings 1110 aand 1110 bfunction as an inlet or an outlet depends on whether air is guided through the air passage 1110 from the second side 1102 to the first side 1101, or vice versa. Generally, the wall passage member 1100 will be arranged such that the inlet / outlet port 1110 ais for receiving air to be discharged from a building interior or for guiding outside air into the building interior. On this basis, the inlet / outlet opening 1110 b would then serve to discharge air from the interior of the building to the outside or to be able to convey outside air to the interior of the building.The wall feedthrough element 1100 further comprises a carrier recess 1120, which extends between the third and fourth sides 1103 and 1104 and is at least open to the first side 1101. A cross section of such a carrier recess 1120 is illustrated in FIG. 6 a.The support recess 1120 may also be open to one of the fifth or sixth sides 1105, 1106, respectively. The cross-section of such a support recess 1120 is illustrated in FIG. 6 b, where the support recess 1120 is also open towards the sixth side 1106. In further such embodiments, the carrier recess 1120 is open toward the fifth side 1105, that is to say is arranged on another other side of the wall leadthrough element 1100. Such a variant is also illustrated in Figures 11-14.The cross section of the carrier recess 1120 may be rectangular in the height direction, as shown in FIGS. 6, 6 aand 6 b, or, as exemplarily illustrated in FIGS. 6 cand 6 d, may be semicircular, quarter circular or otherwise curved. The cross-sectional shape of the carrier recess 1120 is preferably shaped such that it is able to accommodate a part of the load-bearing structure, as explained below. The latter can be positive and non-positive.The carrier recess 1120 serves to arrange the wall feedthrough element 1100 on a load-bearing structure 900. The load-bearing structure 900 may be part of a wall manufactured in truss, wooden stand, wooden skeleton, wooden frame, wooden panel or wooden module construction, such as a post. The load-bearing structure 900 can likewise be part of a steel skeleton or reinforced concrete skeleton construction, for example a steel beam. The load-bearing structure 900 can be part of a wall manufactured in solid construction. As illustrated in FIG. 6 e, the wall passage member 1100 may be disposed, for example, in a brick wall between an upper brick row ZR 1 and a lower brick row ZR 2. In such cases, the carrier recess 1120 may be at least partially filled with a filler FS (e.g. concrete, wood), which may provide for a force dissipation from the upper brick row ZR 1 to the lower brick row ZR 2, for example. Such a filler is also understood as a load-bearing structure 900.As illustrated in FIG. 7, the wall feedthrough element 1100 can comprise an air duct recess 1130 on the second side 1102. The air guide passage recess 1130 is formed such that the inlet / outlet port 1110 bof the air passage 1110 opens into the air guide passage recess 1130. In this way, air, for example air introduced from the outside into the air duct recess 1130, can pass from the air duct recess 1130 into the air passage 1110 and from there into the interior of the building, and / or from the interior of the building through the air passage 1110 into the air duct recess 1130 and from there for example to the outside.The air duct recess 1130 is formed so as to be able to accommodate an air duct. In principle, the air guide duct recess 1130 can be designed such that it can accommodate an air guide duct in a form-fitting and / or force-fitting manner. For this purpose, the air duct recess 1130 can be formed complementary to the regions of a ventilation duct which are to be accommodated there.In the case of a flat channel, the air guide channel recess 1130 may have a cross section transverse to the depth direction as illustrated in FIG. 7 a; i.e. a substantially rectangular cross section. Such an air duct recess 1130 can serve, for example, for receiving a flat duct 1200 illustrated in FIG. 7 b. The flat channel 1200 includes an inlet / outlet opening 1202 and an inlet / outlet opening 1204. The inlet / outlet opening 1202 is provided for fluid communication with the inlet / outlet opening 1110 bof the air passage 1110 in order to be able to bring air from the air passage 1110 into the flat duct 1200 and vice versa. The inlet / outlet opening 1202 may be adjoined by an optional tube RO, which can be introduced at least partially into the air passage 1110. The inlet / outlet opening 1204 of the flat duct 1200 serves to be able to bring air out of the air duct 1200 to the outside (e.g. ambient air) or to a subsequent air duct and vice versa. This is illustrated in FIG. 7 c by the double arrow LFR.The air duct recess 1130 may also be formed so as to be able to accommodate an air duct of variable cross section. Such an air duct 1210 is illustrated in FIGS. 7 dand 7 e. FIG. 7 d shows an exemplary cross section and FIG. 7 e shows an exemplary view of the side of the air duct 1210, where an inlet / outlet opening 1202 is providedThe exemplary air duct 1210 shown there has a wider duct section 1210 a, which can be referred to as cuboidal, and a duct section 1210 b, which adjoins it and has a tapering cross section, followed by a duct section 1210 cin the form of a flat duct. The complementary configuration of an air duct recess 1130 is illustrated in FIG. 7 f.The air guide duct 1210 has an inlet / outlet opening 1202 and an inlet / outlet opening 1204. The inlet / outlet opening 1202 is provided for fluid communication with the inlet / outlet opening 1110 bof the air passage 1110 in order to be able to bring air from the air passage 1110 into the air guide channel 1210 and vice versa. The inlet / outlet opening 1202 may be adjoined by an optional tube RO, which can be introduced at least partially into the air passage 1110. The inlet / outlet opening 1204 of the air duct 1210 serves to be able to bring air out of the air duct 1200 outwards (e.g. ambient air) or to a subsequent air duct and vice versa. This is illustrated in FIG. 7 g by the double arrow LFR. In addition to the inlet / outlet opening 1202, the air duct 1210 has a further inlet / outlet opening 1204. The inlet / outlet opening 1204 of the air guide duct 1210 serves to be able to bring air out of the air guide duct 1210 to the outside (e.g. ambient air) or to a subsequent air guide duct and vice versa. This is illustrated in FIG. 7 g by the double arrow LFR.In other words, in the above embodiments of the air duct recess 1130, it is provided that it extends along the width direction B Q- B Q towards the side 1106 of the cuboid element which is remote from the passage. In other embodiments, the air guide channel recess 1130 may extend along the width direction B Q- B Q towards the side 1106 of the wall leadthrough element 1100 close to the passage.The shape of the air guide channel recess 1130 may change along the width direction B Q- B Q. As shown in FIG. 7 f, the recess can comprise a flat, cuboidal section, which is adjoined in the direction of the side 1106 remote from the passage by a section in the form of a triangular prism. In some embodiments, the one triangular prism-shaped portion may be omitted.The above embodiments of the air duct recess 1130 may be used to bring air from the building interior towards a window or door lintel and vice versa, or as described further below towards a downstream air duct and vice versa.As illustrated in FIG. 8, the air duct recess 1130 can extend along the height direction H Q- H Q for example towards the fourth side 1104 or towards the third side 1103. The variant shown in FIG. 8 is comparable in terms of the configuration of the air-guiding duct recess 1130, considered per se, to that of FIG. 7 a. In other words, the air guide channel recess 1130 may comprise a cuboidal section. However, it is also provided here that configurations of the air duct recess 1130 are used considered per se, which are comparable to those of FIG. 7 f. In other words, a section in the form of a triangular prism can follow a rectangular section.Embodiments of the air duct recess 1130 in the sense of FIG. 8 can be used to be able to bring air from the interior of the building to regions behind a (suspended) facade or a roof transition and vice versa.Generally, the direction of extension of the duct recess 1130 and the direction in which the support recess 1120 extends will be substantially perpendicular to each other. In further embodiments, the direction of extension of the air duct recess 1130 and the direction in which the carrier recess 1120 extends may include any angle.The air passage 1110 may have a round cross section as illustrated in the previous drawings. As shown in FIG. 9 a, the air passage 1110 may have a circular cross-section with radius r D,1( not shown) on the first side 1101 of the wall passage element 1100 and radius r D,2 on the second side 1102 of the wall passage element 1100. In some embodiments, the passage 1110 may have a circular cross-section with a radius that is sectionally or completely constant in the depth direction. As shown in FIG. 9 a, the passage 1110 is arranged at a distance d 2 from the side 1105, close to the passage, of the wall passage element 1100.The passage 1110 may have a rectangular cross-section with width b D,1 and height h D,1( both not shown in FIG. 9 b) on the first side 1101 of the wall feedthrough element 1100 and with width b D,2 and height h D,2 on the second side 1102 of the wall feedthrough element 1100, as shown in FIG. 9 b. In some embodiments, the passage 1110 may have a rectangular cross-section with a height and / or width that is sectionally or completely constant in the depth direction. As shown in FIG. 9 b, the passage 1110 is arranged at a distance from the side 1105, close to the passage, of the wall passage element 1100.As explained above, the carrier recess 1120 can receive a region of a load-bearing structure 900; for example, a vertical section 910 according to the illustration. As illustrated in FIG. 9 a, the carrier recess 1120 may have an extension t in the depth direction T Q- T Q of the cuboid element and an extension b in the width direction B Q- B Q of the cuboid element. The carrier recess 1120 may be arranged at a distance d 1 from the side 1106 of the wall air passage element remote from the passage. In some embodiments, the distance d 1 may be zero, e.g., as illustrated in FIGS. 6 band 6 d. In some embodiments, the support recess 1120 may not extend perpendicularly from the third side 1103 to the fourth side 1104 and may receive an oblique portion of a load bearing structure 900 such as occurs in frameworks.FIG. 10 shows a perspective view of a modular wall feedthrough element 1100. The wall feedthrough element 1100 comprises the modules 1107 a, 1107 b,..., 1107 farranged one behind the other in the depth direction T Q- T Q starting from the second side 1102 of the wall feedthrough element 1100. As illustrated in FIG. 10, the modules 1107 a, 1107 b,..., 1107 fmay have different strengths in the depth direction T Q- T Q of the wall air passage member. In some embodiments, some, multiple, or all of the modules may have the same thickness in the depth direction.The front module 1107 aaccording to the illustration can be referred to as a basic module, in particular if an air duct recess 1130 is formed there. The front side 1102 of the base module 1107a is shown to provide the second side 1102 of the wall feedthrough member 1100.The subsequent modules 1107 b,... may be considered as sub-modules. By selecting the number and / or thickness of the sub-modules, the extent of the wall leadthrough element 1100 in the depth direction can be variably determined.The carrier recess 1120 may be formed in one or more of the sub-modules. If the carrier recess 1120 is formed in only one of the sub-modules, i.e. in the last one in the row 1107 f, the carrier recess 1120 may also extend only partially therethrough.In further embodiments, a combination of a wall air duct member 1100 and a roller shutter / refinery bin 800 is provided to provide a ventilation assembly 1000. In principle, any roller shutter / refinery bin can be used here because, as explained below, it is not changed per se, but rather is given a structure for arranging an air duct. In particular, however, it is provided to use one of the roller shutter / refinery bins explained above with reference to FIGS. 1, 2, 3, 4 to 5. An advantageous embodiment results when an above-described roller shutter / lapse store box of modular construction and a wall air passage element of likewise modular construction are used. This enables a selectively fixable extension in the depth direction.In the following explanations, reference is made to a ventilation arrangement 1000 which, as illustrated in FIGS. 11 and 12, is arranged in a wall structure with a wooden stand construction. The statements made in this regard apply accordingly to any wall structure where there is a load dissipation in the structure 900.As illustrated in FIG. 11, the wall structure there with a wooden stand construction shows uprights 900 which are oriented vertically according to the illustration and cross-members 902 which are oriented horizontally according to the illustration. A roller shutter / lapse store box 800 (hereinafter abbreviated box) is disposed between and usually attached to two adjacent posts 900 aand 900 b. The fact that the box 800 extends over the entire distance between the two adjacent posts 900 and adjoins the latter may be due, for example, to the fact that a window extending over the entire width between the posts is located below the box 800.As shown, the wall air passage member 1100 is narrower as viewed in the width direction so as not to span the entire distance between the two adjacent posts 900 band 900 cbetween which it is disposed. This is based on the approach of dimensioning the wall air passage element 1100 at least just such that the air passage 1110 can be accommodated. In this way, the space remaining between the wall air passage element 1100 and the post 900 cto which the wall air passage element 1100 does not reach can be used elsewhere. In further embodiments, however, wall air passage elements 1100 are provided, which extend completely between two adjacent uprights.As illustrated, the wall air passage member 1100 is arranged such that a portion 910 of the post 900 bis received in the support recess 1120. There, the wall air passage element 1100 can be connected to the post 900 b. In the variant shown here, a carrier recess 1120 is provided in the sense of FIGS. 6 aand 6 d, i.e. one which is open to the first side 1101 and to the sixth side 1106. The carrier recess 1120 allows the post 900 bto be left unchanged and does not have to impair its load-bearing function. Furthermore, the space in front of the post 900 bmay be used as illustrated. This space is denoted by R in FIG. 11.This space can be used, for example, to arrange an air-guiding channel recess 1130; at least parts thereof. This is illustrated in FIG. 12 where an air duct recess 1130 also extends into the space R. Furthermore, FIG. 12 shows an air duct 1300 which is arranged on the front side VS (which is also denoted at 132 above with reference to FIGS. 1, 2, 3, 4 to 5 ) of the box 800.The ventilation duct 1300 has an inlet / outlet opening 1302 and an inlet / outlet opening 1304.The inlet / outlet opening 1302 is provided for fluid connection with the inlet / outlet opening 1204 of an air duct 1200 / 1210arranged in the air duct recess 1130, and serves to be able to supply air from this to the ventilation duct 1300 and vice versa.The inlet / outlet opening 1304 serves to be able to bring air out of the air guide duct 1300 to the outside (e.g. ambient air) or to a subsequent air guide duct and vice versa.FIG. 13 illustrates a cross-sectional view of the assembly of FIG. 12 transverse to the height direction. In addition, FIG. 13 also shows an air duct arranged in the air duct recess 1130; here, for example, the air duct 1210 explained above. In the region denoted by V, the inlet / outlet opening 1302 of the air duct 1300 and the inlet / outlet opening 1204 of the air duct 1210 are connected to one another; preferably in a fluid-tight manner, such that no air can emerge there. This arrangement enables air to be conveyed through the air passage 1120, the air guide duct 1210, and the air guide duct 1300, and vice versa.To cover the air duct 1300, a cover AD can be provided on the front side VS of the box 800. This can be produced, for example, using wood. The cover AD can have an air duct recess 1400, which can be shaped complementarily to the shape of the air duct 1300 used in each case. FIG. 14 shows such an exemplary air duct recess 1400, which is suitable for receiving the air duct 1300 of FIGS. 12 and 13.
