Description

Thermal engineering plant

Technical Field

The utility model relates to a thermal technology equipment. The thermal engineering device comprises a compression device and a foam body, wherein a holding device comprising a damping element is provided for the fixed but detachable connection of the compression device to the foam body, said holding device having a holding element which is partially encapsulated in the foam body by foaming and which is connected to the damping element.

Background

A thermal engineering plant of the type mentioned at the outset is known from DE 202009013995U 1. The thermal engineering device is composed in particular of a compression device and of a foam body, wherein a holding device comprising a damping element is provided for fixedly but detachably connecting the compression device to the foam body, wherein the holding device has a holding element which is partially encapsulated in the foam body by foaming and which is connected to the damping element.

Furthermore, another thermal engineering device of interest is known from DE 202006015443U 1.

SUMMERY OF THE UTILITY MODEL

The invention is based on the object of improving a thermal engineering device of the type mentioned at the outset, more precisely in particular with regard to further improvement in the vibration damping and thus with regard to reduction of the sound radiation.

This object is achieved by a thermal engineering device of the type mentioned at the outset, with the features listed in the present invention.

According to a first aspect, a thermal engineering device is proposed, comprising a compression device and a foam body, wherein a holding device is provided, which comprises a damping element, for the fixed but detachable connection of the compression device to the foam body, with the holding device having a holding element, which is partially encapsulated in the foam body by foaming and which is connected to the damping element. According to the invention, the foam body at least partially surrounds a mass element, the mass of which is several times greater than the mass of the compression device.

In other words, the solution according to the invention is characterized in that the damping element is not supported on the foam body by a form-locking manner as in DE 202006015443U 1, but rather an additional retaining element, which is partially encapsulated in the foam body by the foam, is provided, to which the damping element is fastened and to which the compression device is fastened in turn. Thus, vibrations from the (operating) compression device are first transmitted to and damped by the damping element. Here, the transmitted vibrations cannot lead to: the damping element is released from the foam body because the damping element is fixedly connected with the retaining element according to the invention and the retaining element is fixedly connected with the foam body (due to foaming).

In this case, particularly good damping is achieved because the foam body at least partially surrounds a mass element whose mass is several times greater than the mass of the compression device, wherein it is also particularly preferred to provide a water storage device as the mass element. In this case, for example, a mass ratio of 350kg (water storage device) to 10kg (compression device) is obtained, i.e. vibrations from the compression device which is elastically connected to the water storage device are damped very well due to the large mass of the water storage device.

Further advantageous embodiments of the thermal engineering device according to the invention result from the preferred embodiments.

For completeness, reference is also made to the further-mentioned documents DE 8129010U 1 and DE 102004032920 a 1.

According to one embodiment of the invention, the retaining element is formed by a platform that is accessible from the outside of the foam body and by at least one anchoring element that is provided with at least one hole and is encapsulated in the foam body by the foam.

According to a further embodiment of the invention, it is provided that the damping element is arranged fixedly, but detachably, on a platform provided with screw holes.

According to a further embodiment of the invention, the platform has a polygonal basic shape, wherein a damping element is arranged at each corner.

According to a further embodiment of the invention, the mass element is designed as a water storage device.

According to a further embodiment of the invention, the foam of the foam body is arranged between the mass element and the anchoring element.

According to a further embodiment of the invention, a line, which is designed to be selectively connected on one side to the compression device or to a component arranged on the compression device and on the other side to a further component of the thermal engineering plant, is arranged fixedly on the holding element.

According to a further embodiment of the invention, a further line, which is designed to be selectively connected on one side to the compression device or to a component arranged on the compression device and on the other side to a further component of the thermal engineering plant, is designed in such a way that it is partially encapsulated in the foam by foaming.

According to a further embodiment of the invention, a support element provided with a threaded bore is provided on the compression device, on which support element the damping element is arranged in a fixed, but detachable manner on the support element side.

Drawings

In the following, the thermal engineering device according to the invention and its advantageous embodiments according to the invention are explained in more detail with the aid of a diagrammatic representation of a preferred embodiment.

Schematically shown in cross-section:

fig. 1 shows a heat-engineering plant with a compression device and a foamed water storage device, which is designed as an industrial water heat pump.

Detailed Description

The heat-technical system shown in the single figure, which is particularly preferably designed as an industrial water heat pump (for the sake of clarity, other system parts are not additionally shown), in particular, consists of a compression device 1 and a foam body 2, wherein a holding device containing a damping element 3 is provided for fixedly but detachably connecting the compression device 1 to the foam body 2, wherein the holding device has a holding element 4 which is partially encapsulated in the foam body 2 by foaming and is connected to the damping element 3. The compression device is particularly preferably arranged above the foam body 2.

It is now important for the thermal engineering device according to the invention that the foam body 2 at least partially, preferably completely (as shown) surrounds a mass element 5, the mass of which is several times greater than the mass of the compression device 1. This embodiment results in particularly good damping, wherein the mass element 5 is also particularly preferably designed as a water accumulator, as in the case of the industrial water heat pump shown. If the foam of the foam body 2 performs an adhesive function during foaming, the retaining element 4 is therefore connected not only in a form-fitting manner but also in a material-fitting manner to the foam body 2.

As explained at the outset, this very tight connection between the compression device and the foam body, which is produced by foaming, leads to particularly good vibration damping.

More precisely, it is particularly preferably provided here that the holding element 4 is formed by a platform 4.1 which is accessible from outside the foam body 2 and by at least one anchoring element 4.2 which is encapsulated in the foam body 2 by foaming and which is preferably provided with at least one (screw) hole 4.3. This provision results in the aforementioned tight connection between the foam body 2 and the retaining element 4, which connection cannot be separated without being destroyed. The anchoring element 4.2 is here located within the foam body 2, while the platform 4.1 is arranged on the foam body 2 in a manner that is well accessible from the outside for assembly. Depending on requirements, the holding element 4 can be formed in one piece from the platform 4.1 and the anchoring element 4.2; alternatively, it is also possible for the holding element 4 to be formed from the part in two parts. In this case, at least the anchoring element 4.2 cannot (without destruction) come loose from the foam body 2.

Furthermore, it is provided that the damping element 3 is arranged, preferably in a fixed but detachable manner, on a platform 4.1, which is preferably provided with threaded holes. The platform 4.1 here particularly preferably has a triangular basic shape, wherein one damping element 3 is arranged at each tip or corner (principle of a three-legged chair which cannot be "tilted"). Alternatively, however, the platform 4.1 can also be designed as a rectangle, square or other polygon. In this case, particularly cylindrical rubber cushions are preferably provided as damping elements 3, wherein the anchor plate is pre-fastened to these rubber cushions (shown in the figures) both on the platform side and on the compressor side with corresponding threaded bolts.

As can be seen from fig. 1, it is also preferably provided that the foam of the foam body 2 is arranged between the mass element 5 and the anchoring element 4.2, i.e. it is ensured according to the invention that the retaining element 4 or the anchoring element 4.2 does not come into direct contact with the mass element 5. The contact between these two parts is produced by the foam material of the foam body. The selection of a suitable foam material (polystyrene, assembled foam, foam glass, etc.) is made by the person skilled in the art as a function of the application or the purpose of use.

With reference again to fig. 1, a support element 8, which is preferably provided with threaded bores, is arranged on the compression device 1, on which support element the damping element 3 is preferably arranged fixedly, but detachably. Here, it is also provided in this case that the carrier element 8 has a polygonal, particularly preferably triangular basic shape, wherein one damping element 3 is arranged at each point or corner. The support element 8 can be designed as a separate component, but can also be designed as part of the compression device 1 (for example welded on).

Since the compression device 1 is usually connected, in particular in the case of a compression device designed as a heat pump, via lines (in particular suction line and pressure line) to further (practically vibration-free) components of the heat pump, which are usually also arranged in the illustrated housing, a first advantageous development of the system attachment described (shown on the left in fig. 1) consists in that a line 6, which is designed to be selectively connected on one side to the compression device 1 or to a component arranged on the compression device 1 and on the other side to another component (not shown) of the thermal engineering plant, is fixedly arranged on the holding element 4. Due to this provision, the vibrations induced into the line 6 from the compression device 1 can be conducted away by the holding element 4, so that the line 6 can be guided virtually vibration-free to other components of the thermal engineering apparatus after the fixing.

Finally, a second advantageous embodiment of the described system connection consists in (shown on the right in fig. 1): a further line 7, which is configured to be selectively connected on one side to the compression device 1 or to a component arranged on the compression device 1 and on the other side to a further component of the thermal engineering apparatus (not shown), is configured in such a way that it is partially encapsulated in the foam body 2 by foaming. As will be appreciated based on the above explanation, this specification is also well suited to account for effective vibration decoupling.
