In order to specify a component that is easier to mount on the ground, for example on a flat roof, a vibration damping device should be provided between the top of at least one frame element (1), preferably the top of all frame elements (1), on the one hand and the underside of the component on the other , whereby the component rests on the base frame exclusively through the vibration damping device.

Description

The invention relates to a component of an air conditioning and / or room ventilation system, the component having a base frame consisting of frame elements on the underside for arrangement on a substrate, for example on a flat roof. The component can be, for example, a fan, a filter, a heat exchanger or the like, or a combination of several components and / or subcomponents.

In practice, components in the form of cuboid housings are known in which air conditioning and / or air conditioning components and subcomponents, such as fans, filters, heat exchangers or the like, are arranged. These are configurable central air conditioning units which, depending on the configuration, can be used for ventilation of rooms and buildings, for filtering, for heating, for cooling, for heat recovery as well as for humidification and dehumidification.

The housings with the air conditioning and / or ventilation components and subcomponents contained therein are mounted on flat roofs, for example. For this purpose, strips of an insulating material must first be applied to the flat roof in the areas in which the base frame rests on the flat roof be put on. The insulating material prevents any vibrations caused by the operation of subcomponents, such as fans, from being transmitted via the base frame into the ground. For this purpose, the strips must be precisely positioned so that the base frame rests precisely on the strip when the housing is in the detached state. However, positioning the housing is difficult for many reasons. Thus, a housing has a high weight and large dimensions, for example 4 mx 2 m. Furthermore, in the case of large dimensions, the base frame includes, in addition to the four frame elements arranged in the area of the outer edges, also further "intermediate" frame elements which are covered by the four outer frame elements. In addition, the surface of the insulating material is anti-slip in order to prevent the housing from slipping on the ground during later operation. Therefore, once the housing has come into contact with the surface of the insulating material, the position of a housing can only be changed with difficulty. In this respect, assembly is difficult, especially in cases in which two housings still have to be assembled one below the other.

The object of the invention is to avoid the aforementioned disadvantages and to specify a component that can be more easily mounted on the ground, for example on a flat roof.

This object is achieved in that a vibration damping device is provided between the upper side of at least one frame element, preferably the upper side of all frame elements, on the one hand and the underside of the component on the other hand, the component resting on the base frame exclusively through the vibration damping device. In this way, the base frame is decoupled from the component by the vibration damping device. As a result of the configuration according to the invention, the component can already be completely installed on the base frame at the factory and only needs to be placed on the ground, for example the flat roof, on site. Any alignment is no longer necessary. The base frame is in direct contact with the subsurface, so that even if it is uneven The base frame rests perfectly on the ground. If desired, the base frame can also be fixed to the base, for example by screwing.

The vibration damping device can be designed in one piece. In such a configuration, the vibration damping device forms a type of frame.

Of course, the vibration damping device can also have a plurality of subregions distributed along the base frame. For example, if the base frame consists of four frame elements, it is conceivable that, for example, a partial area is arranged in the area of each end of the four frame elements. In such a configuration, the component rests on the base frame at six points due to the vibration damping device.

At least a partial area of the vibration damping device can be flat. In the case of a flat configuration, the sub-area is designed, for example, in the manner of a strip. For example, the strip can only cover a partial area, i. H. cover a section of a frame element. However, it is also entirely possible that a partial area of the vibration damping device, which is designed, for example, in the manner of a strip, extends, for example, over the entire length and the entire width of a frame element. If a partial area of the vibration damping device extends over the entire length and the entire width of a frame element, it covers the entire area of the frame element.

The vibration damping device or at least a partial area of the vibration damping device can be fixed in a vibration-decoupled manner relative to the component by means of at least one fastening device, preferably by means of a screw.

In the component, at least one fastening element interacting with a fastening device, preferably a rivet nut for Receiving a screw may be provided. A rivet nut or a welded nut offers the advantage that a rivet nut or a welded nut does not turn when the screw is screwed in and therefore does not have to be held. This means that they do not have to be accessible during the screwing process.

To pass through at least one fastening device, preferably a screw, the vibration damping device or at least a partial area of the vibration damping device on the one hand and the associated frame element on the other hand can each have at least one aligned recess.

The vibration damping device or at least a partial area of the vibration damping device can also be designed as a combination of a spring, preferably a spiral spring, and a damper, preferably a shock absorber.

The vibration damping device or at least a partial area of the vibration damping device can be designed as a body made of foam or rubber or cork or another suitable material that dampens vibrations, such as polyvinyl chloride (PVC) or rubber, the body having a top, a Has the bottom and a side wall connecting the top and the bottom, and wherein the body rests with its top directly or indirectly on the bottom of the component and with its bottom directly or indirectly on the frame element.

The selection of foam or rubber or cork or another suitable material that dampens vibrations depends on the prevailing surface pressure [N / mm ² ], which results from the weight of the component to be damped and the contact surface. The support surface is the surface with which the vibration damping device or a partial area of the vibration damping device is in contact with the component or with the base frame. The mechanical loss factor that causes the Describes the strength of the vibration damping (frequency, load and amplitude dependent) and which can assume a high value, has an influence.

A foam is understood to be a foam that consists, for example, of polyvinyl chloride, polystyrene or polyurethane. Vibrations or oscillations are absorbed by the foam and converted into heat. This achieves damping and prevents vibrations or oscillations of the component from being completely submerged via the base frame. A suitable foam is available under the name Sylomer®. Sylomer® is particularly suitable for use as a pressure-loaded spring. Sylomer® forms a flat, elastic layer. Sylomer® is a special polyurethane (PUR) elastomer.

Depending on the prevailing surface pressure [N / mm ² ], a polyurethane (PUR) elastomer foam, such as the foam sold under the name Sylomer®, with the following specifications, where the shear modulus describes the rigidity of the foam: static application range up to [N / mm ² ] Mechanical loss factor [η] static shear modulus [N / mm ² ] dynamic shear modulus [N / mm ² ] 0.011 0.25 0.03 0.10 0.018 0.23 0.05 0.12 0.028 0.21 0.07 0.15 0.042 0.16 0.08 0.17 1,200 0.09 0.90 1.60

At least one body can have a rectangular cross section. Thus, in the unloaded state, the body can have a height H _K of 25 mm, ie the side wall is 25 mm high and has a width B of 50 mm, ie the top and bottom each have a width B of 50 mm. If the body is designed as a strip, the body has the shape of a cuboid. However, the body can also be designed, for example, as a circular disk with a rectangular cross section.

It is advisable if the vibration damping device or at least a partial area of the vibration damping device compresses the vibration damping device or the partial area of the vibration damping device in the range between 2% and 10%, preferably 8%, based on the height H _{K of} the vibration damping device or in the static load range of the partial area of the vibration damping device, but a maximum of 4 mm, preferably a maximum of 2 mm, based on the height H _{K of} the vibration damping device or the partial area of the vibration damping device.

Between the vibration damping device or between at least a partial area of the vibration damping device on the one hand and the frame element on the other hand, a cover element can be provided which partially, preferably completely, covers the surface of the vibration damping device facing the frame element or at least a partial area of the vibration damping device. In this respect, the cover element covers at least a partial area of the vibration damping device or at least a partial area of at least a partial area of the vibration damping device. In practice, the vibration damping device rests with its underside on the frame element arranged below. In this respect, at least a partial area of the underside, preferably the entire underside, of the vibration damping device or at least a partial area of the vibration damping device is covered by the cover element. The cover element distributes the force acting on the vibration damping device from the frame element over a larger area. The cover element can for example consist of metal.

At least one cover element can be designed as a profile element which has at least one wall pointing from the frame element in the direction of the underside of the component, at least one wall being arranged at a distance from the adjacent side of the body forming a gap and the height H of the wall being smaller than the height H _{K of} the body. In such a configuration comes the profile element primarily a privacy protection function, since the relevant side of the vibration damping device is at least partially covered by the respective adjacent wall. Due to the gap, the vibration damping device cannot come into contact with the wall, so that when the vibration damping device is displaced, no friction with the adjacent wall can arise. The height H of the wall is selected in relation to the height H _{K of} the body in such a way that in the detached state the edge of the wall does not come into contact with the underside of the component.

The vibration damping device or at least a partial area of the vibration damping device can have a lower thermal conductivity λ than the thermal conductivity λ of steel. The thermal conductivity λ of steel is approximately between 15 W / (m K) and 50 W / (m K), while the thermal conductivity λ of the vibration damping device or at least a sub-area of the vibration damping device is less than 2 W / (mK), preferably less than 1 W / ( mK), particularly preferably less than 0.1 W / (mK). This achieves thermal decoupling between the base frame and the component. Thermal decoupling can also be achieved by lengthening the distance, for example by providing a spiral spring as a component of the vibration damping device.

At least one frame element can be designed as an L-shaped profile. In such a configuration, the profile resembles the profile of a double T-beam.

At least one frame element can be designed as a C-shaped profile with the formation of two legs and a connecting web connecting the two legs. The end of each of the two legs can preferably also be angled in the direction of the other leg.

It is advisable if the component is a cuboid, in particular cube-shaped, housing for accommodating air conditioning and / or air conditioning subcomponents, such as a fan, a filter, a Heat exchanger or the like, is formed, wherein the housing is spanned by six open surface areas to form a bottom area, four lateral surface areas and a lid area, and wherein the bottom area and the lid area are each closed by a panel element and also each side surface area, provided the housing with this open lateral surface area, at least in a partial area of this lateral surface area, does not cooperate in a sealing manner with the open lateral surface area of an adjacent housing, is closed with a panel element. Air conditioning and / or air conditioning components and subcomponents, such as fans, filters, heat exchangers or the like, are arranged in the housing. These are then configurable central air conditioning units which, depending on the configuration, can be used for ventilation of rooms and buildings, for filtering, for heating, for cooling, for heat recovery as well as for humidifying and dehumidifying. In such a configuration, a vibration damping device is provided between the underside of the panel element (panel elements) closing the floor area on the one hand and the top of at least one frame element, preferably all frame elements, on the other.

In all figures, identical reference symbols are used for identical or similar components.

In the figures, a component designed as a cuboid housing for accommodating air conditioning and / or air conditioning subcomponents, such as a fan, a filter, a heat exchanger or the like, is partially shown.

The component, which is designed as a housing, has a base frame consisting of frame elements 1 on the underside for arrangement on a substrate (not shown). The housing has a rectangular plan. How Fig. 2 As can be seen, in addition to the frame elements 1 arranged in the area of the outer edges of the housing, the base frame also includes two "intermediate" frame elements 1 which are covered by the outer frame elements 1. Each frame element 1 is designed as a C-shaped profile with the formation of two legs 2 and a connecting web 3 connecting the two legs 2, the end of each of the two legs 2 being angled in the direction of the other leg 2.

Fig. 4 shows the partial area of the housing in which an "intermediate" frame element 1 is connected to a frame element 1 arranged in the area of the outer edge of the housing. How Fig. 4 As can be seen, the “intermediate” frame element 1 has an angled area 16 with holes 17 in its end area. This angled area 16 allows the "intermediate" frame element 1 to be screwed to the frame element 1 arranged in the area of the outer edge of the housing.

In Fig. 5 the area of a corner of the housing is shown in which two frame elements 1 arranged in the area of the outer edges of the housing meet. The left frame element 1 has the angled area 16 described above with holes 17, so that the two frame elements 1 arranged in the area of the outer edges of the housing can be screwed together by means of screws (not shown).

The housing is spanned by six open surface areas to form a base area, four lateral surface areas and a cover area. In the exemplary embodiment shown, the bottom area, the lid area and each of the four lateral surface areas are each closed with two panel elements 4, the panel elements 4 closing the lid area and the four lateral surface areas not being shown in the figures.

A vibration damping device is provided between the top of all frame elements 1 on the one hand and the bottom of the component designed as a housing on the other hand. This means that the component rests on the base frame exclusively through the vibration damping device.

The vibration damping device has a plurality of partial areas 5 distributed along the base frame, each partial area 5 of the vibration damping device being flat. Each sub-area 5 is strip-shaped. In the illustrated embodiment, each sub-area 5 of the vibration damping device is designed as a body made of a foam, the body having a top 19, a bottom 20 and a side wall 21 connecting the top 19 and the bottom 20. The upper side 19 of the body rests indirectly on the underside of the panel element 4 which closes the base area and with its underside 20 directly on the frame element 1. The body has - as in Fig. 6 recognizable - in the illustrated embodiment a rectangular cross-section, the body in the illustrated embodiment has a height H _K of in the unloaded state 25 mm and a width B of 50 mm. The body is designed as a strip and extends over the entire width and over the entire length of a frame element 1 and in this respect covers the top of the frame element 1 over the entire surface.

Each sub-area 5 of the vibration damping device is fixed by means of at least one fastening device, which is designed as a screw 6, with respect to the panel element 4, which closes the base area, and thus the component.

In the component, in the present case in the panel element 4 which closes the bottom area, at least one fastening element in the form of a rivet nut 7, which interacts with the screw, is provided for receiving the screw 6. To pass through the screw 6, each sub-area 5 of the vibration damping device on the one hand and the associated frame element 1 on the other hand each have an aligned recess 8, 9.

For each sub-area 5 of the vibration damping device, a cover element 10 is provided on the surface that interacts with the frame element 1. The cover element 10 covers the sub-area 5 of the vibration damping device on the underside. The cover element 10 distributes the force acting on the vibration damping device from the frame element 1 over a larger area. The cover element 10 is made of metal, for example, and in turn has a recess 11 which is aligned with the recesses 8, 9.

As can be seen from the figures, each cover element 10 is designed as a profile element which has two opposite walls 12, 13 pointing from the frame element 1 in the direction of the underside of the component. Each of the two walls 12, 13 is arranged at a distance from the adjoining side of the body, forming a gap 18. The height H of both walls 12, 13 is less than the height H _{K of} the body. As can be seen from the figures, the height H of the wall 12 is that of the interior of the base frame is facing, lower than the height H of the wall 13, which points outwards.

When mounting the frame elements 1 on the underside of the panel element 4 closing the bottom area, the body part 5 of the vibration damping device is first placed on the underside of the panel element 4 and the cover element 10 is brought into position. First a hard washer 14 and then a soft washer 15 is placed on the screw 6. The frame element 1 is then brought into its assembly position and the screw 6 is inserted through the aligned recesses 8, 9, 11 into the rivet nut 7 and screwed in.

In the illustrated embodiment, the body, which consists of foam, has a height H _K of 25 mm and a width B of 50 mm in the unloaded state. When the component is placed on top of the base frame during assembly, the partial area 5 of the vibration damping device is compressed in the direction of arrow 22. In the static load area, the sub-area 5 is compressed by a maximum of 2 mm in relation to the height H _{K of} the sub-area 5, ie by 4% in relation to the height H _{K of} the sub-area 5.
