Description

The invention relates to a device for air conditioning and / or monitoring of building or storage areas.

The WO 2008/040266 A2 relates to a device for air conditioning and / or monitoring of housing areas, including at least one vertically arranged, at least partially formed as a hollow body, if necessary, composed of segments housing predeterminable height, for concealed receiving components / components for air conditioning, such as fan rollers, motors or the like , and / or the monitoring of the respective building area is provided, wherein the housing is fixed in the region of at least one of its end faces, stationary or arranged in the region of at least one of its end faces guide means movably disposed in the respective building area and the housing over a predetermined height of its lower portion has a self-reinforcing vertical area.

The fan rollers addressed here have vertically extending guide vanes, the reinforcing rings, as required, comprise in combination with elastic bands to the specified high speeds to meet (min ^-1 2000).

A disadvantage of such a construction is that the guide vanes are usually made of metal and are designed to extend in a straight line. Due to the high peripheral speeds very high noise levels occur. Although the use of such devices has proven itself in practice, where, however, where persons are active in the immediate vicinity of the device, the sound levels are clearly too high about 70 dB (A) at 3 m distance).

The aim of the subject invention is to develop the device described above to the effect that on the one hand a simple structure is given and the device on the other hand, regardless of the fan rollers used and the enforced air volumes, also has an improved noise behavior.

The object of the subject invention is also to provide a method for producing a device for air conditioning and / or monitoring of building and / or storage areas, which is simple in construction and can be installed in a very short time.

This object is achieved by a device for air conditioning and / or monitoring of building or storage areas, comprising a housing made of plastic or composite designed as a hollow body having air inlet, air ducting and air outlet sections, at least one, driven by at least one electric motor with a plurality of profiled trained laminations made of composite materials or plastic, fan roller, which is positionable within the housing and a lining for the housing, formed by a flexible plastic or composite plate, which is connectable to the housing, wherein an end portion of the panel with a housing portion is detachably connectable, by bending the panel outside the housing a cross-section approximately arcuate contour thereof is formed and after further bending of the panel, the free end of the same at another housing section Lö sbar is determinable.

Advantageous developments of the subject invention can be found in the dependent claims.

This object is also achieved by a method for producing a device for air conditioning and / or monitoring of building or storage areas, at least including at least one housing, at least one associated fan roller and at least one serving as a panel plate, wherein the housing components, fan roller and trim made of plastic or a composite material and at least one electric motor by the at least one housing is composed of cut plastic or composite parts, the at least one fan roller in the associated Housing is used, the electric motor is coated in analogy to the respective fan roller with wall portions of plastic or composite material, at least one fan roller positioned in the upper and lower portions of the electric motor and the connection areas of the same is brought into operative connection, the plate with cutouts for the air intake and the Air outlet is provided and the plate is releasably connected by bending about its longitudinal axis with housing portions of the at least one housing.

Advantageous developments of the method according to the invention can be found in the associated subclaims.

As plastic materials on the one hand for the housing and on the other hand for the flexible plastic plate, materials such as polycarbonate or the like are used. Polycarbonates are plastics from the group of synthetic polymers and the family of polyesters. Widely used are polycarbonates which use bisphenol A as the diol component and phosgene. These are usually amorphous and have a crystal content of <5%. They are characterized by high strength, impact resistance, rigidity and hardness.

By the use of composite materials / plastics for the device according to the invention selbige is easy to build and can be converted in a few simple steps in a working condition.

In order to optimize the efficiency of the fan rollers, provided within the housing air guide elements are necessary. To optimize the resonance behavior, the entire housing with all components of the already mentioned plastic material manufactured. For the necessary flow behavior at the air outlet area are bodies which advantageously have the shape of a triangle, integrated in the housing. The fan roller facing surface of these bodies is provided with a profiled surface or openings to break the emitted resonances of the fan roller (s). The housing is in this case designed so that the diameter of different sized fan rollers can be used.

It is particularly advantageous that the air guide elements, depending on the different diameters of the fan rollers, can be adjusted within the housing.

The housing side provided exhaust louvers in the air outlet portions of the housing, in accordance with another aspect of the invention, the shape of an aircraft wing to realize the Coanda effect for speed optimization and increasing the speed.

It is particularly advantageous to construct the fan rollers in a modular manner in conjunction with the electric motor in order to design a type of modular system in this manner.

A high efficiency of the device requires a high number of revolutions of the fan rollers.

As already mentioned, the blades are made in conventional fan rollers made of metal, in particular aluminum, and arranged vertically. This arrangement of the slats has the consequence that the air masses to be conveyed are cut. This creates an unpleasant high whistling at the high speed that people perceive as disturbing in the immediate vicinity of the respective device. The inventive oblique arrangement (profiling) is achieved a kind of twisting of a composite material, respectively a suitable plastic, existing slats in their longitudinal direction.

Due to this twisting, the air masses to be conveyed are unrolled (peeled). In addition, it is advantageous if the lamellae get a rounding. This requires a further reduction of the noise.

By modular construction of the modules cost-effective production of the entire device can now be realized. Here it makes sense to connect the electric motor with the respective fan rollers by means of prefabricated plug connections. This also has the advantage that the construction can be adapted to the height and width of the respective entrance / gate. The respective modules can already be prefabricated and do not have to be designed as a single construction. Another advantage is that in case of failure of a module only the respective module must be changed.

For the arrangement, a cladding of the modules, respectively the housing, is necessary. The cladding provides the modules, respectively the housing, stability and forms a further noise insulation for the roller system. Again, a special plastic / a special plastic compound is used. The main body for the cladding is designed as a flexible plastic plate specifiable length and width.

The plastic plate is seen on one side of the housing, over its height, releasably fixed, then guided along one of the housing surfaces and bent outside of this housing surface, such that after about 180 ° bend a rounded cross-section formed section is formed. The round arch thus formed serves to accommodate bulbs and the electronics used as needed, respectively components for security purposes. By further bending the free end of the plastic plate can also be releasably secured to another housing surface. The plastic plate can be cut and mounted in any desired color.

It is particularly advantageous if the cladding is at least partially made of luminous thin-film components made of organic semiconducting materials, respectively provided with it.

In addition, it is also conceivable to manufacture the cladding completely from such materials and to provide it as a flexible screen. By this measure, it is possible to present information / advertising for customers and the like.

FIG. 1 shows a cross section through the housing 1 of the device according to the invention, including components provided therein. In this context, the state of the art according to WO 2008/040266 A2 directed. The height of the housing 1 can be formed as shown in the prior art to bridge the necessary opening portions of a building or a warehouse can.

Within the housing 1, a plurality of vertically superposed fan rollers 2,2 'are preferably positioned. The same are in the Figures 2 and 3 described in more detail. The fan rollers 2,2 'have to enforce different amounts of air different diameters. The housing 1 has a here only indicated air inlet section 3, a curved air guide element 4, in the region of an air guide section between the fan rollers 2,2 'and the air guide 4 is an approximately triangular shaped air guide 5 and air outlet sections 6. The curved air guide element 4 is with a sliding mechanism 7, by means of which the spoiler 4 can be adjusted to adapt to different sized fan rollers 2,2 '. The same applies to the air guide element 5, which also has a gate 8, by means of which it can be adjusted in the direction of the fan roller 2,2 '. The housing 1 in this example has a square cross-section and is made of the wall thickness forth relatively thin-walled (5-10 mm). The housing 1 is made of plastic, for example polycarbonate. Are used plastic plates specifiable length, width and thickness, which are brought together, for example by gluing in operative connection.

Due to this construction, a defined gap 9 is formed in the air inlet region 3, between the respective fan roller 2,2 'and the correspondingly positioned air guide element 4, in which a compression of the sucked air takes place. After passing through the fan roller 2,2 ', the air enters an enlarged space 10 in which it can relax. The exhaust fins 11, which are provided in the region of the air outlet sections 6, in this example have the shape of an aircraft wing, in order to realize in this way the Coanda effect for speed optimization and increasing the speed. Seen in the longitudinal direction of the air guide element 5, the surface 12 of this air guide element 5 is provided with profiles 13, for example in the form of openings, in order to be able to receive the emitted resonances of the fan rollers 2, 2 '. Compared to the prior art can be optimized with the subject invention, the resonance behavior. As a result of the now given low noise of the device according to the invention also persons, without having to expect damage to health, can work in the immediate vicinity of the device.

FIG. 2 shows a schematic diagram of a single fan roller 2, which has either a continuous shaft 14 or shaft approaches. The fan roller 2 has a multiplicity of lamellae 15, which-in contrast to the prior art-are arranged not vertically but inclined, in particular twisted. Deviating from the prior art, the air mass to be conveyed is no longer cut, but rather by the oblique arrangement of the fins 15, the air mass to be conveyed is unrolled (peeled). As indicated, each blade 15 is provided with a rounding 16. At least the fins 15 are made of a composite material or a plastic specifiable Shore hardness. Composites may be, for example, carbon fibers in combination with a suitable plastic / resin. Due to the oblique arrangement of the fins 15, the previously unpleasant high whistling can be at least substantially reduced.

FIG. 3 shows a schematic diagram of a modular structure of several fan rollers 2 in operative connection with an electric motor 17. The components 2,17 can be easily connected to each other to realize different requirements, for example by means of prefabricated connectors 18, with the shafts 14 / shaft extensions of the fan rollers 2. The electric motor 17 and the fan rollers 2 can, in contrast to the prior art, now be prefabricated and not always be made new. This has the advantage that in case of failure of a component 2,17 only the respective component 2,17 must be replaced. Over in the left picture the FIG. 3 shown further connectors 18 ', the free ends of the respective fan roller 2 can be brought into operative connection with components of the housing not shown here.

FIG. 4 shows the housing 1 of the device according to the invention in cross section. Indicated by arrows is on the one hand the air inlet section 3 and on the other hand the air outlet section 6. For further noise reduction and for receiving only indicated bulbs 19 is a panel 20 is used, which is made of a plastic plate, for example of a soft polycarbonate, and has a high flexibility , With regard to the hardness, it must be ensured that a, for example, intelligent plastic material is used, which is deformed back into its original position even when external forces are applied. Only indicated is a section 21 which engages over the air inlet section 3. In the same way, this also applies to the region of the air outlet section 6 (not shown). The panel 20 will, as in the upper part of the FIG. 4 indicated in the region of a surface 22 of the housing portion 22 'detachably fixed, guided along this surface 22 and then bent such that a portion 23 is formed with arcuate contour 24. By further bending the panel 20 and along a surface 22 opposite the surface 25 of the housing 1, the free end 26 of the panel 20 can also be releasably connected to another housing portion 27 in operative connection. The cladding 20 can, in the region of the section 23, be formed at least partially transparent, so that the lighting means 19 can be used effectively. In the area of the section 23 further components, such as electronic elements or security elements for a retail security system can be integrated, which are then provided at areas of the section 23, which are not transparent. The sum of the technical effects realized in this novel device causes a reduction of the noise level by at least 30 dB.

Instead of the cladding 20 made of plastic here, it is also possible to use a cladding (not shown) which consists partly or completely of luminous thin-film components made of organic semiconducting materials (OLED). By this term the expert understands organic Light emitting diodes (organic light emitting diodes), as they are increasingly used today for screens (eg TVs, monitors or the like). Thus, the device can also be used as an advertising medium / information carrier if necessary.

FIG. 5 shows a schematic diagram of the individual components of the device according to the invention, wherein the assembly process is explained in principle. Identical components are provided with the same reference numerals.

As already in FIG. 3 indicated and also in the WO 2008/040266 A2 described, the device consists of several individual housing elements 1 '. Each housing element 1 'is in this example composed of cut-out plastic elements and serves to receive a respective fan roller 2,2'. In the same way, the electric motor 17 is surrounded by a sheath 17 'made of plastic elements. By arranging a plurality of housing elements 1 'and the sheath 17', any desired housing length of the device can be generated. In the next step, the panel 20 is analogous to FIG. 4 with the housing 1 forming housing elements 1 'brought into operative connection. Depending on the height of the device, the panel 20 in one piece or in several parts - as in FIG. 5 shown - trained. Can be seen sections 21 ', which engage over the air outlet portions 6 of the housing elements 1'. Before the panel 20 is brought into operative connection with the housing elements 1 ', 6 exhaust grille 28 are applied to the air outlet sections. For the required air intake intake grille 29 are then placed on the housing elements 1 'and the panel 20. In order to stabilize the overall housing 1 existing caps 30, respectively bottom plates 31 are applied in the upper and lower portions of the associated housing elements 1 'made of plastic. The bottom plate 31 can be prefabricated here for drilling with holes or recesses 32 for quick installation.
