Device for the air-conditioning and/or monitoring of building or warehouse areas, containing a housing consisting of plastic or composite material shaped as a hollow body and having air entry, air guidance and air exit sections, at least one fan roller provided with a plurality of profiled fins made of composite material or plastic, and drivable by at least one electric motor, the fan roller being positionable inside the housing, and a casing for the housing, formed by a flexible plastic or composite material panel that can be connected to the housing, wherein an end section of the casing can be releasably connected to a housing section, an approximately arc-shaped contour of the casing is formed by bending the casing lying outside the housing, and after further bending of the casing, the free end thereof can be releasably fastened to a different housing section.
The invention relates to a device for air conditioning and/or monitoring of building or warehouse areas.
WO 2008/040266 A2 relates to a device for air conditioning and/or monitoring of building areas, containing at least a vertically disposed housing, which is configured, at least in certain sections, as a hollow body, and composed of segments, if necessary, and has a predeterminable height, which housing is provided for covered accommodation of components/modules for air conditioning, such as fan rollers, motors or the like, and/or for monitoring of the building area, in each instance, whereby the housing is disposed to be fixed in place in the area of at least one of its face surfaces, to be stationary or movable by way of guide means provided in the area of at least one of its face surfaces, in the building area, in each instance, and the housing has a vertical area that reinforces it, by way of a predeterminable height of its lower section.
The fan rollers addressed here have guide vanes that run vertically, if necessary in combination with elastic bands, in order to meet the requirements of the high speeds of rotation (2000 rpm) indicated.
It is a disadvantage of such a design that the guide vanes usually consist of metal and are configured to run in a straight line. Because of the high circumferential speeds, very high noise levels occur. It is true that the use of such devices has proven itself in practice, but the noise levels are clearly too high approximately 70 dB(A) at a distance of 3 m) where people are working in the immediate vicinity of the device.
It is the goal of the object of the invention to further develop the device described above to the effect that on the one hand, a simple structure exists, and on the other hand, the device also has improved noise behavior, independent of the fan rollers used and of the air amounts passed through.
It is also the goal of the object of the invention to make available a method for the production of a device for air conditioning and/or monitoring of building and/or warehouse areas, which device is simple in structure and can be installed within the shortest possible time.
This goal is achieved by a device for air conditioning and/or monitoring of building and/or warehouse areas, containing a housing configured from plastic or composite material, as a hollow body, which housing has air entry, air guidance, and air exit sections; at least one fan roller that can be driven by at least one electric motor, having a plurality of profiled fins configured from composite materials or plastic, which roller can be positioned within the housing; and a casing for the housing, formed by a flexible plastic or composite material panel that can be connected with the housing, wherein an end section of the casing can be releasably connected with a housing section, an approximately arc-shaped contour of the casing, in cross-section, is formed by bending the casing outside of the housing, and, after further bending of the casing, the free end of the casing can be releasably fixed in place on a different housing section.
Advantageous further developments of the object of the invention can be derived from the dependent claims.
This goal is also achieved by a method for the production of a device for air conditioning and/or monitoring of building or warehouse areas, at least containing at least one housing, at least one related fan roller, and at least one panel that serves as a casing, wherein the components, the housing, the fan roller, and the casing, consist of plastic or a composite material, as well as at least one electric motor, in that the at least one housing is composed of cut-out plastic or composite material parts, the at least one fan roller is inserted into the related housing, the electric motor is jacketed, by analogy to the fan roller, in each instance, with wall areas composed of plastic or composite material, at least one fan roller is disposed in the upper and lower section of the electric motor and brought into an operative connection with connection areas of the motor, the panel is provided with cut-outs for air intake and air exit, and the panel is releasably connected with housing sections of the at least one housing, by being bent about its longitudinal axis.
Advantageous further developments of the method according to the invention can be derived from the related dependent method claims.
Materials such as polycarbonate or the like can be used as plastic materials for the housing, on the one hand, and for the flexible plastic panel, on the other hand. Polycarbonates are plastics from the group of synthetic polymers and the family of polyesters. Polycarbonates that use bisphenol A as the diol component and phosgene are widespread. These are generally amorphous and have a crystalline component of <5%. They are characterized by great strength, impact resistance, rigidity, and hardness.
By means of the use of composite materials/plastics for the device according to the invention, the device has a light construction and can be converted to a state ready for operation, using only a few hand motions.
In order to optimize the degree of effectiveness of the fan rollers, air guide elements provided within the housing are required. For optimization of the resonance behavior, the entire housing, with all the components, is produced from the plastic material that has already been addressed. For the required flow behavior at the air exit area, bodies that advantageously have the shape of a triangle are integrated into the housing. The surface of these bodies, facing the fan rollers, is provided with a profiled surface area or openings, in order to break the indicated resonances of the fan roller(s). In this connection, the housing is configured in such a manner that fan rollers of different sizes, in terms of their diameter, can be used.
It is particularly advantageous that the air guide elements can be adjusted within the housing, as a function of the different diameters of the fan rollers.
The blow-out fins provided on the housing side, in the area of the air exit sections of the housing, have the shape of an airplane wing, in accordance with another idea of the invention, in order to implement the Coanda effect for velocity optimization and an increase in velocity.
It is particularly advantageous to configure the fan rollers in modular manner, in connection with the electric motor, in order to design a type of modular system in this manner.
A high degree of effectiveness of the device presupposes a high speed of rotation of the fan rollers.
As has already been addressed, the fins in conventional fan rollers are made from metal, particularly aluminum, and disposed vertically. This arrangement of the fins has the result that the air masses to be conveyed are cut. This results in an unpleasant, high whistling noise at the high speed of rotation, which persons in the immediate vicinity of the device, in each instance, perceive as disturbing. Because of the slanted arrangement (profiling) according to the invention, a kind of twisting of the fins, which consist of a composite material or, respectively, of a suitable plastic, in their longitudinal direction is achieved. Because of this twisting, the air masses to be conveyed are rolled off (peeled). Furthermore, it is advantageous if the fins have a rounded part. This results in a further reduction in the noises.
By means of the modular production of the modules, cost-advantageous production of the entire device can now be implemented. In this connection, it makes sense to connect the electric motor with the fan rollers, in each instance, by means of pre-fabricated plug-in connections. The advantage that the design can be adapted to the height and width of the entry/gate, in each instance, is also connected with this The modules, in each instance, can already be pre-fabricated and do not have to be structured as individual constructions. It is furthermore advantageous that in the event of failure of a module, only the respective module has to be replaced.
For the arrangement, a casing of the modules, i.e. of the housing is required. The casing offers the modules, i.e. the housing, stability and forms further noise insulation for the roller system. Here, too, a special plastic/a special plastic compound is used. The basic body for the casing is configured as a flexible plastic panel having a predeterminable length and width.
The plastic panel is releasably fixed in place on the housing, viewed over the housing height, subsequently guided along one of the housing surfaces and bent outside of this housing surface, in such a manner that after a bend of about 180°, a section that is configured rounded in cross-section is formed. The round arc formed in this way serves for accommodating illuminants and the electronics that are used, if necessary, i.e. components for safety purposes. By means of further bending, the free end of the plastic panel can also be releasably fixed in place on a different housing surface. In this connection, the plastic panel can be cut to size and installed, in any desired color.
it is particularly advantageous if the casing is produced from or provided with luminous thin-layer components made of organic semiconductive materials, at least in part.
Furthermore, it is also possible to produce the casing entirely from such materials and to provide it as a bendable screen. By means of this measure, the possibility exists of offering information/advertising for customers and the like.
The object of the invention is shown in the drawing, using an exemplary embodiment, and will be described below. The drawing shows:
Preferably, multiple fan rollers 2, 2′ disposed vertically one on top of the other are positioned within the housing 1. These rollers are described in greater detail in
As a result of this design, a defined gap 9 is formed in the air entry area 3, between the fan roller 2, 2′, in each instance, and the correspondingly positioned air guide element 4, in which gap compression of the air drawn in takes place. After passing by the fan roller 2, 2′, the air enters into an enlarged space 10, in which it can relax. The blow-out fins 11, which are provided in the area of the air exit sections 6, have the shape of an airplane wing in this example, in order to thereby implement the Coanda effect for velocity optimization and an increase in velocity. Seen in the longitudinal direction of the air guide element 5, the surface area 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 absorb the resonances given off by the fan rollers 2, 2′. As compared with the state of the art, the resonance behavior can be optimized with the object of the invention. As a result of the low noise level of the device according to the invention that now exists, persons can now work in the immediate vicinity of the device without having to expect injury to their health.
In place of the casing 20 produced from plastic here, a casing (not shown) can also be used, which consists partially or entirely of luminous thin-layer components made from organic semiconductive materials (OLED). A person skilled in the art understands this term to mean organic light-emitting diodes ([in English:] organic light emitting diodes), as they are increasingly being used for screens (e.g. TVs, monitors or the like) nowadays. Thus, the device can also be used as an advertising medium/informational medium, if required.
