Description

The invention relates to a heat distribution system according to the preamble of patent claim 1.

A heat distribution system of the type mentioned is from the patent document DE 198 03 154 A1 famous. This consists of at least a first and a second cuboid housing, each with a height, a width and a depth, the depth of the housing being less than 350 mm, with each housing having at least two surfaces, one surface of the first housing being one surface of the second housing facing, hydraulic tubing being provided in at least one housing, the tubing having at least two flow cross sections, the two flow cross sections being arranged at the same height in the housing.

The object of the invention is to improve a heat distribution system of the type mentioned at the outset. In particular, a heat distribution system that is particularly easy and time-saving to install with a small footprint is to be created, which can also be easily expanded and flexibly arranged.

This object is achieved with a heat distribution system of the type mentioned by the features listed in the characterizing part of patent claim 1.

According to the invention, it is therefore provided that one flow cross section is assigned to one surface and the other flow cross section to the other surface of the housing and that at least one drinking water reservoir is provided in one housing, which optionally consists of at least two tanks or one at least twice as wide as deep trained tank is formed.

In other words, despite the presence of a drinking water reservoir, the heat distribution system according to the invention is characterized by a very flat modular design that makes installation easier thanks to the flow cross sections, which are preferably (which will be explained below) designed as connections.

The above-mentioned stipulation that one flow cross section is assigned to one surface and the other flow cross section to the other surface of the housing expresses on the one hand that flow cross sections or, in particular, connections are provided in at least one of the housings at two different points. On the other hand, this requirement also means that one flow cross section is accessible in the area of the surface of one housing and can be connected there, for example, to another flow cross section of another housing that is assigned to the corresponding opposite surface there. The two surfaces thus form a parting plane between two flow cross sections or, in particular, connections belonging to different housings.

Other advantageous developments of the heat distribution system according to the invention result from the dependent patent claims.

For the sake of completeness, reference is also made to the following prior art (sorted by first priority): DE 24 06 570 A1 , AT 345 942 B , DE 34 16 574 A1 , FR 2 627 260 A1 , US 5,429,113A , EP 0 766 048 A1 , DE 197 17 655 A1 , EP 1 243 868 A2 , WO 2010/019978 A2 , DE 10 2009 021 928 A1 , EP 2 944 893 A1 , WO 2011/104592 A1 , WO 2012/110713 A1 , DE 10 2017 211 482 A1 , GB 2561706A , EP 3 444 538 A1 .

very diagrammatically and in perspective a first embodiment of the heat distribution system with the piping according to the invention, in this case a heat source and a hot water storage tank consisting of two tanks; and

figure 2

from the front (and without panel) a second embodiment of the heat distribution system according to the invention with hot water tank, heat pump, ventilation system and battery power storage.

The heat distribution system shown in the figures initially consists, in a known manner, and this applies to all conceivable embodiments, of at least a first and a second cuboid housing 1, 2, each with a height H, a width B and a depth T. Regarding the aforementioned sizes H, B and T is on figure 1 referenced, in which, as the stipulation "at least" requires as a minimum, a heat distribution system with exactly two housings is shown, with further optional cuboid housings being indicated by dashed lines. figure 2 shows a heat distribution system with a total of six housings, which will be discussed in more detail below.

In addition, each housing 1, 2 has at least two surfaces 1.1, 1.2, 2.1, 2.2, wherein a surface 1.2 of the first housing 1 is assigned to a surface 2.1 of the second housing 2 facing. As can be seen particularly well from FIG. 1, it is preferably provided that said surfaces 1.2, 2.1 are arranged so as to run parallel to one another. Provision is also particularly preferably made for the two surfaces 1.2, 2.1 to be designed as side surfaces of the housings 1, 2 facing one another. Furthermore, with regard to the two surfaces 1.1, 1.2, 2.1, 2.2, it is preferably provided that these are designed to extend in the height and depth direction of the housing 1, 2.

Alternatively, it can also be provided that the two surfaces 1.2, 2.1 are formed by the rear sides of the housing 1, 2, so that the modules or housing are arranged back-to-back, so to speak.

Furthermore, it is preferably provided that the housings 1, 2 each have a front side and a rear side extending in the height and width direction. It is also preferably provided that the back faces a building wall is trained. Furthermore, it is preferably provided that the front is designed as an openable panel, this panel, which is typically designed as a smooth, for example formed from sheet metal and visually appealing surface or the like, in the Figures 1 and 2 is not shown to allow an insight into the housing.

In order to realize a design that is as flat as possible, it is also preferably provided that the depth of the housing 1, 2 is at most half the width of the housing 1, 2. According to a further provision, it is preferably provided that the height of the housing 1, 2 is at least is one and a half times as large as the width of the housing 1, 2. Furthermore, it is preferably provided that the height of the housing 1, 2 is at least four times as large as the depth of the housing 1, 2. These provisions can be ensured that the inventive Housing 1, 2 used even in the flattest niches of a building, but still all the necessary components of the heating system can be included. In addition, the dimensions mentioned (height, width, depth) are deliberately chosen so that the modules or housing are easy to transport. If the modules were higher, deeper or wider, you could no longer carry them through a door. The same applies to the weight per module that can be carried by two people.

Like in particular figure 1 As can be seen, on the one hand always the same housing components can be used, but on the other hand also to create a uniform overall impression, it is particularly preferred that the housings 1, 2 all have the same depth.

With regard to the arrangement of the housing 1, 2 in the room of a building, which is not explicitly shown in the figures, it is particularly preferably provided that these are designed to be wall-mounted. For this purpose, suitable hooks are attached to the wall and the housing 1, 2 is hung on them, possibly even before the screed is created. The distance between the housing 1, 2 after hanging to the finished floor can, how ultimately figure 1 results to be very low.

Irrespective of whether the housings 1, 2 are hung on a building wall or not, it is also preferably provided that they are connected to one another via at least one horizontal rail (in particular on the back of the housings 1, 2). Two rails are particularly preferably provided, namely one at the top and one at the bottom of the housing, so that a fixed distance between the housings 1, 2 can be produced in a particularly simple manner.

In a manner known per se is also in particular with reference to figure 1 provided that in at least one housing 1, 2, a hydraulic piping 3 is provided. This has at least two flow cross sections 3.1, 3.2, which are arranged at the same height in the housing 1, 2.

What is essential for the heat distribution system according to the invention is that one flow cross section 3.1 is assigned to one surface 1.1, 2.1 and the other flow cross section 3.2 to the other surface 1.2, 2.2 of the housing 1, 2 and that at least one drinking water storage tank 4 is provided in a housing 1, 2 is, the optional (as shown) from at least two tanks 4.1, 4.2 or (not shown separately) from at least one twice as wide as deeply trained tank is formed.

This requirement makes it possible to completely pre-assemble the housing 1, 2 together with its internal technical equipment and then to be able to deliver it as finished modules to the construction site or to the installation site.

As already mentioned at the beginning, it is particularly preferred that at least one flow cross section 3.1, 3.2 (preferably all) is (are) designed as a connection (i.e. in particular as a pipe end piece with a connecting means for connection to another pipe end piece), since in this way forms an interface level for the tubing 3 in the contact level between the two surfaces 1.2, 2.1. Alternatively, it is also possible that said connections or pipe end pieces are not arranged in the contact plane between the two surfaces 1, 2.

How to continue figure 1 apparent ( figure 2 is not so clear with regard to said piping due to pipe facings), it is further preferably provided that the piping 3 has a horizontal pipe section running from one surface 1.1, 1.2, 2.1, 2.2 to the other.

Furthermore, as in figure 1 shown in greatly simplified form, it is preferably provided that the piping 3 is hydraulically optionally connected to a heat source and/or heat sink 5 arranged in at least one housing 1, 2 and/or to the drinking water reservoir 4.

A heat source is to be understood, for example, as a heat generator (such as a boiler or a heat pump), but also simply as a hot water connection supplied from outside the housing 1 , 2 . The term heat sink is to be understood accordingly, namely as such a device via which heat can ultimately be dissipated from the housing 1, 2, for example a cold water connection that makes cold water available to which heat can be supplied.

Furthermore, in order to be able to use the space in the housings 1, 2 well for the actual installations, which will be discussed in more detail below, it is particularly preferred that the two flow cross sections 3.1, 3.2 are optionally in an upper or a lower quarter of the housing 1, 2 are arranged.

In all cases, it is also provided that the depth of the housing 1, 2 is less than 350 mm, particularly preferably even less than 300 mm, ie the housing is built very flat, especially with regard to the drinking water reservoir. In this context, as can be seen from the figures, it is further particularly preferred that the tanks 4.1, 4.2—which is particularly pressure-resistant compared to an alternatively provided (see above), preferably cuboid tank—are designed cylindrically with a vertically oriented cylinder axis . In figure 1 is a solution with two tanks 4.1, 4.2, in figure 2 even a solution with four tanks is shown, although in figure 2 two tanks 4.1, 4.2 are arranged in a common housing.

In order to also be able to provide a sufficient amount of warm drinking water, it is also provided that the drinking water reservoir 4 extends over at least three quarters of the height of the housing 1, 2 is formed.

Regarding the aforementioned internals is now on figure 2 referred.

According to this embodiment, it is preferably provided that at least part of a heat pump 5.1, preferably the internal unit of a heat pump, is arranged in one of the housings 1, 2. In order to be able to defrost any icing that may occur on the outdoor unit of the heat pump, it is also particularly preferred that the heat pump 5.1 be provided with a defrosting buffer 5.2, which is also arranged in one of the housings 1, 2 (see, for example, the patent document DE 10 2018 102 670 A1 - simply called buffer storage there) is assigned.

Furthermore, as in figure 2 to recognize, it is preferably provided that in one of the housings 1, 2 a ventilation system 6, a battery storage device 7, an expansion tank 8, preferably and optionally a drinking water and/or heating circuit expansion tank, and an electric heater 5.3 for hot water generation, in particular hot water for a heating circuit , is arranged. As is readily apparent, all of the built-in components mentioned can be provided in the heat distribution system according to the invention, but do not have to be, ie such a system according to the invention is also possible without the use of a battery power store 7, for example.

Finally, in order to form a so-called installation rail, it is particularly preferred that a support device (not shown separately) for receiving the hydraulic tubing 3 is arranged in the housing 1 , 2 . The carrier device is particularly preferably provided in at least two housings 1, 2, preferably in all of the housings used.
