Description

  The present invention relates to an apparatus for air conditioning and / or monitoring a building area or a warehouse area.

  WO 2008/040266 relates to a device for air conditioning and / or monitoring a building area. The building area includes a housing of a predetermined height, vertically assembled and at least partially configured as a hollow body, optionally assembled from a plurality of segments. The housing is provided to blindly contain components / components for air conditioning and / or monitoring of each building area, such as fan rollers, motors, etc. Fixed in at least one area of the end face and arranged in each building area in a fixed position or movably via guide means provided in at least one of the end faces, the housing having a section below it A vertical region that reinforces the housing over a predetermined height.

The fan roller described in the above pamphlet includes a guide blade (blade) extending vertically. The guide blade is provided with a reinforcing ring combined with an elastic belt, if necessary, in order to adapt to the stated high speed (2000 min ⁻¹ ).

  The disadvantage of such a structure is that the guide blade is usually made of metal and is configured to extend straight. Due to the high peripheral speed, a very high noise level is produced. Although the use of such a device has been demonstrated, where the person is active right next to the device, the sound pressure level is clearly too high to be about 70 dB (A) at a distance of 3 m.

  The object of the present invention is to improve the aforementioned device, on the one hand a simple structure, on the other hand also having improved noise characteristics independent of the fan roller used and the amount of air to be passed. Is to do so.

  It is a further object of the present invention to provide a method for manufacturing a device for air conditioning and / or monitoring a building area and / or a warehouse area that is simple in construction and can be assembled in a short time.

  The object is to provide a device for temperature regulation and / or monitoring of a building area or a warehouse area, which is made of a plastic or composite material and is configured as a hollow body, the housing comprising an air inflow section and an air guide. At least one fan roller having a housing and a plurality of blades made of composite material or plastic, which can be driven by at least one electric motor, and has a section and an air outflow section, Is a decorative cover for the housing, formed by a fan roller and a flexible plastic sheet or composite sheet, which can be positioned inside the housing, the decorative cover being connectable to the housing; In that case, the end section of the decorative cover is a predetermined housing section. The decorative cover is detachably connectable, and bending the decorative cover outside the housing forms a substantially arched profile of the decorative cover, and after further bending the decorative cover, the decorative cover It is solved by a device for temperature regulation and / or monitoring of a building area or warehouse area, characterized in that it comprises a decorative cover, the free end of which is removably fixable to another housing section.

  Further preferred embodiments of the object of the invention are evident from the dependent claims.

  The subject is a method of manufacturing a device for temperature regulation and / or monitoring of a building area or a warehouse area, comprising at least one housing, an associated at least one fan roller, and at least one used as a decorative cover. The seat, the at least one electric motor, and the components, which are the housing, the fan roller, and the decorative cover, are made of plastic or a composite material, and the at least one housing is made of a plurality of cut plastics. Assembled from a part or composite part, the at least one fan roller is inserted into the attached housing, the electric motor, like each fan roller, is surrounded by a wall region made of plastic or composite material, and at least one Two fan rollers on the upper and lower sides of the electric motor The sheet is operatively coupled to the connection area of the electric motor, the sheet is provided with cutout portions for intake and air outflow, and the sheet is bent about the longitudinal axis of the sheet This is solved by a method for manufacturing a device for temperature regulation and / or monitoring of a building area or a warehouse area, characterized in that it is removably coupled to a housing section of said at least one housing.

  Further preferred embodiments of the method according to the invention are evident from the appended dependent claims relating to the method.

  Materials such as polycarbonate are used as the plastic material for the housing on the one hand and the flexible plastic sheet on the other hand. Polycarbonate is a plastic consisting of a group of synthetic polymers and a polyester family. Polycarbonates using bisphenol A and phosgene as diol components are widely known. Polycarbonate is usually amorphous and has a proportion of crystals of less than 5%. Polycarbonate is excellent in high strength, impact strength, stability and hardness.

  By using a composite / plastic in the device according to the invention, the device is easy to assemble and can be moved to a functional state with few operations.

  In order to optimize the efficiency of the fan roller, an air guide element provided inside the housing is required. In order to optimize the resonance characteristics, the entire housing, including all components, is made from the plastic material described above. Due to the required flow characteristics in the air outflow region, a body preferably having a triangular shape is incorporated in the housing. The surface of the body facing the fan roller is provided with a deformed surface or opening, which reduces the resonance generated by the fan roller. In this case, the housing is configured so that fan rollers having various diameters can be used.

  Particularly preferably, the air guide element can be adjusted and moved inside the housing in response to various diameters of the fan roller.

  The blow-off fins provided on the housing side in the area of the air outflow section of the housing, according to another idea of the invention, have the form of an aircraft wing, which allows for speed optimization and speed increase. Coanda effect is realized.

  Particularly preferably, the fan roller, in combination with the electric motor, is configured in a modular manner, thus constituting a kind of assembly system.

  The high efficiency of the device assumes a high fan roller speed.

  As mentioned above, the blades in the conventional fan roller are made of metal, in particular aluminum, and are arranged vertically. As a result of this blade arrangement, the air mass to be transported is cut off. As a result, in the case of a high rotational speed, unpleasant large noises that people feel annoyed beside each device are generated. Due to the oblique arrangement (profile) according to the invention, a certain twist in the longitudinal direction of the blade made of composite material or suitable plastic is achieved.

  Due to this twist, the air mass to be conveyed is rolled (stripped). More preferably, the blade has a rounded portion. This further reduces noise.

  Economical production of the entire device can be realized by assembly of modules. In this case, it is meaningful to couple the electric motor to each fan roller using a prefabricated plug-in connection. This provides the advantage that the structure can be adapted to the height and width of each entrance / gate. Each module can already be prefabricated and need not be configured as a single structure. According to a further advantage, in the event of a module failure, only each module needs to be replaced.

  Such an arrangement requires a decorative cover of the module or housing. The decorative cover provides stability to the module or housing and forms an additional sound insulation for the roller system. Again, special plastic / special plastic composites are used. The base body for the decorative cover is configured as a flexible plastic sheet having a predetermined length and width.

  The plastic sheet is detachably fixed to the housing on one side over its height, subsequently guided along one of the housing surfaces, bent outside the housing surface and bent 180 degrees, A section with a round shape is generated. The round arch so formed serves to accommodate lighting means and electronic devices used as needed or components for security purposes. By continuing further bending, the free end of the plastic sheet can be detachably fixed to another housing surface as well. In this case, the plastic sheet can be cut and assembled with any desired color.

  Particularly preferably, the decorative cover is at least partly made of or provided on a light-emitting thin film element made of an organic semiconductor material.

  It is also conceivable that the decorative cover is made entirely from such a material and is provided as a flexible display. With such a configuration means, there is a possibility of providing customer information / advertisements and the like.

  The subject of the present invention is illustrated based on one aspect and described below.

Figure 2 is a cross-sectional view of a housing according to the present invention including components provided on the inside. It is a principle diagram of each fan roller. It is a principle diagram of a modular structure of a plurality of fan rollers including a motor. It is a figure which shows a decorative cover and shows the assembly | attachment process of the decorative cover with respect to a housing roughly. It is a figure which shows each component of an apparatus and demonstrates an assembly | attachment process.

  FIG. 1 shows a housing 1 of the device according to the invention in cross-section with the components provided on the inside. For this, refer to the background art described in WO2008 / 040266 pamphlet. The height of the housing 1 may be configured as described in the background art so that it can cover the required opening of a building or warehouse.

  Inside the housing 1, a plurality of fan rollers (impellers) 2 and 2 ', which are preferably arranged vertically in the vertical direction, are positioned. The fan rollers 2 and 2 'are shown in detail in FIGS. The fan rollers 2 and 2 'have various diameters for allowing various amounts of air to flow therethrough. The housing 1 is substantially in the region of the air inflow section 3 which is only suggested in FIG. 1, the air guide element 4 formed in a curved shape, and the area of the air guide section between the fan rollers 2, 2 ′ and the air guide element 4. An air guide element 5 formed in a triangular shape and an air outflow section 6 are provided. The air guide element 4 formed in a curved shape is provided with a slide mechanism 7 by which the air guide element 4 is adapted to the fan rollers 2 and 2 ′ having various dimensions. Can be moved for adjustment. The same applies to the air guide element 5. The air guide element 5 likewise comprises a slide link 8, by means of which the air guide element 5 can be adjusted and moved towards the fan rollers 2, 2 '. In this embodiment, the housing 1 has a rectangular cross section, and the wall thickness is relatively thin (5 to 10 mm). The housing 1 is made of plastic, for example polycarbonate. A plurality of plastic sheets of a predetermined length, width and thickness are used. These plastic sheets are operatively bonded to each other, for example, by adhesion.

  Due to such a structure, a predetermined gap 9 is formed in the air inflow region 3 between each fan roller 2, 2 ′ and the air guide element 4 positioned accordingly. In the gap 9, the sucked air is compressed. After passing through the fan rollers 2, 2 ′, air flows into the enlarged space 10. Within this space 10, the air can expand. The blowing fins 11 are provided in the region of the air outflow section 6 and in this aspect the blowing fins 11 have the form of an aircraft wing, and thus a Coanda for speed optimization and acceleration. The effect can be realized. When viewed in the longitudinal direction of the air guide element 5, the surface 12 of the air guide element 5 is provided with a molding portion 13, for example, in the form of an opening, whereby the resonance generated by the fan rollers 2, 2 ′ is generated. Can be absorbed. With respect to the background art, the resonance characteristics can be optimized by the subject of the present invention. Based on the low noise generated in the device according to the invention, a person can work right next to the device without having to expect a health hazard.

  FIG. 2 shows a principle diagram of each fan roller 2 having a continuously extending shaft 14 and a shaft addition portion. The fan roller 2 includes a large number of blades 15, which are differently shaped, unlike the background art, and are not vertically but inclined and are particularly twisted. Unlike the background art, the air mass to be transported is no longer cut off, but rather, due to the oblique arrangement of the blades 15, the air mass to be transported is rolled (stripped). As shown schematically, each blade 15 has a rounded portion 16. At least the blade 15 is manufactured from a composite material or plastic having a predetermined Shore hardness. The composite material may be, for example, carbon fibers combined with a suitable plastic resin. Due to the slanted arrangement of the blades 15, large noise that has been unpleasant until now can be reduced at least significantly.

  FIG. 3 shows a principle diagram of a modular structure of a plurality of fan rollers 2 operatively coupled to one electric motor 17. The components 2 and 17 can be coupled to each other without problems to the shaft 14 / shaft addition of the fan roller 2 by means of a prefabricated plug-in connection 18, for example, in order to fulfill various requirements. The electric motor 17 and the fan roller 2 can now be pre-fabricated with respect to the background art and do not have to be made up constantly. This has the advantage that only the components 2 and 17 need to be replaced when the components 2 and 17 fail. The free end of each fan roller 2 can be operatively coupled to a housing component not shown via another plug connection 18 'shown on the left side of FIG.

  FIG. 4 shows a housing 1 of the device according to the invention in a cross-sectional view. The arrows indicate the air inflow section 3 on the one hand and the air outflow section 6 on the other hand. A decorative cover 20 is used for further noise reduction as well as for the attachment of the illumination means 19 only schematically. The decorative cover 20 is formed of, for example, a plastic sheet made of soft polycarbonate and has high flexibility. With regard to the hardness, for example, it is considered that an intelligent plastic is used which is deformed back to its initial position even in the case of external force action. The section or cutout 21 covering the air inflow section 3 is only shown schematically. This also applies to the region of the air outlet 6 (not shown). The decorative cover 20 is removably secured in the region of the face 22 of the housing section 22 'and is guided along this face 22, as suggested in the upper part of FIG. Is bent so that a section 23 having a contour 24 is formed. By further bending the decorative cover 20 and guiding it along the surface 25 of the housing 1 opposite to the surface 22, the free end 26 of the decorative cover 20 is again detachable, It can be operatively coupled to the housing section 27. The decorative cover 20 may be configured to be at least partially transparent in the region of the section 23, so that the illumination means 19 can be used effectively. In the area of section 23, further components such as security elements or electronic elements for a security system (security gate) can be assembled. In this case, further components are provided in the non-transparent areas of the section 23. When combined with the technical effects realized in such a new configuration, the noise level is reduced by at least 30 dB.

  Instead of the decorative cover 20 made of the illustrated plastic, a decorative cover (not shown) formed from a light-emitting thin film element (OLED) partially or completely made of an organic semiconductor material can also be used. . In that concept, experts interpret it as organic light emitting diodes, which are now increasingly used for screens (eg, televisions, displays, etc.). Therefore, the device can also be used as an advertisement carrier / information carrier as required.

  FIG. 5 shows the principle diagram of the individual components of the device according to the invention. FIG. 5 illustrates the assembly process in principle. The same constituent elements are provided with the same reference numerals.

Each housing element 1 'is assembled from a plurality of cut plastic elements in this embodiment and is used to accommodate one fan roller 2, 2', respectively. Similarly, the electric motor 17 is surrounded by a cover 17 'made of plastic elements. Any arbitrary housing length of the device can be produced by arranging the housing elements 1 'and the cover 17' one above the other. In the next step, the decorative cover 20 is operatively coupled to the housing element 1 ′ forming the housing 1 in the same way as in FIG. 4. Depending on the structural height of the device, the decorative cover 20 may be formed integrally or from a plurality of parts (as shown in FIG. 5). A section 21 'covering the air outflow section 6 of the housing element 1' can be seen. Before the decorative cover 20 is operatively coupled to the housing element 1 ′, the blowing grid 28 is attached to the air outlet section 6. For the required intake, the intake grid 29 is subsequently fitted to the housing element 1 ′ and the decorative cover 20. To stabilize the entire housing 1 as required, caps 30 or bottom plates 31 made of plastic are attached to the upper and lower sections of the attached housing element 1 '. In this case, the bottom plate 31 may be preliminarily formed with holes or recesses 32 for quick assembly.
