Description

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

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

The invention is based on the object of improving a heat distribution system of the type mentioned above. In particular, the aim is to create a heat distribution system that is particularly easy and time-saving to install, has a small footprint, is easily expandable, and can be arranged flexibly.

This object is achieved with a heat distribution system of the type mentioned at the outset by the features listed in the characterising part of 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 storage tank is provided in a housing, which is optionally formed from at least two tanks or from a tank at least twice as wide as it is deep.

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

The above-mentioned requirement 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 at two different locations in at least one of the housings. 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, which is assigned to the corresponding opposite surface there. The two surfaces thus form a dividing 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 claims.

For the sake of completeness, the following, more remote state of the art is also mentioned (sorted by first priority): DE 24 06 570 A1 , AT 345 942 B , DE 34 16 574 A1 , FR 2 627 260 A1 , US 5,429,113 A , 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 2561706 A , EP 3 444 538 A1 .

The heat distribution system according to the invention, including its advantageous developments according to the dependent claims, is explained in more detail below with reference to the drawings of two exemplary embodiments.

• 1 sehr schematisch und perspektivisch eine erste Ausführungsform der Wärmeverteilanlage mit der erfindungsgemäßen, in diesem Fall eine Wärmequelle und einen aus zwei Tanks bestehenden Warmwasserspeicher verbindenden Verrohrung; und
• 2 von vorne (und ohne Verkleidung) eine zweite Ausführungsform der erfindungsgemäßen Wärmeverteilanlage mit Warmwasserspeicher, Wärmepumpe, Lüftungsanlage und Batteriestromspeicher.

It shows

• 1 very schematically and in perspective a first embodiment of the heat distribution system with the piping according to the invention, in this case connecting a heat source and a hot water storage tank consisting of two tanks; and
• 2 from the front (and without cladding) a second embodiment of the heat distribution system according to the invention with hot water storage, heat pump, ventilation system and battery power storage.

The heat distribution system shown in the figures consists in a known manner, and this applies to all conceivable embodiments, of at least a first and a second cuboid-shaped housing 1, 2, each with a height H, a width B and a depth T. With regard to the aforementioned dimensions H, B and T, 1 in which, as the requirement “at least” requires as a minimum, a heat distribution system with exactly two housings is shown, with further optional cuboid-shaped housings indicated by dashed lines. 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 face a surface 2.1 of the second housing 2. Preferably, as can be seen particularly well from 1 As can be seen, it is provided that the said surfaces 1.2, 2.1 are arranged parallel to one another. Furthermore, it is particularly preferred that the two surfaces 1.2, 2.1 are designed as mutually facing side surfaces of the housings 1, 2. Furthermore, with regard to the two surfaces 1.1, 1.2, 2.1, 2.2, it is preferably provided that they are designed to extend in the height and depth directions of the housings 1, 2.

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

Furthermore, it is preferably provided that the housings 1, 2 each have a front and a rear side extending in the height and width directions. It is further preferably provided that the rear side is designed to face a building wall. Furthermore, it is preferably provided that the front side is designed as an openable panel, wherein this panel, which is typically designed as a smooth, visually appealing surface, for example made of sheet metal or the like, 1 and 2 is not shown to allow a view into the housing.

In order to achieve the flattest possible design, it is furthermore preferably provided that the depth of the housings 1, 2 is at most half the width of the housings 1, 2. According to a further requirement, it is preferably provided that the height of the housings 1, 2 is at least one and a half times the width of the housings 1, 2. Furthermore, it is preferably provided that the height of the housings 1, 2 is at least four times the depth of the housings 1, 2. These requirements can ensure that the housings 1, 2 according to the invention can be installed even in the shallowest niches of a building, but can still accommodate all the necessary components of the heating system. Furthermore, the aforementioned dimensions (height, width, depth) were deliberately chosen so that the modules or housings are easy to transport. If the modules were higher, deeper, or wider, they could no longer be carried through a door. The same applies to the weight per module that can still be carried by two people.

As is particularly evident from 1 As can be seen, in order to always be able to use the same housing components on the one hand, but also to create a uniform overall impression on the other hand, it is particularly preferred that the housings 1, 2 all have the same depth.

Regarding the arrangement of the housings 1, 2 within a building, it is particularly preferred, although this is not explicitly shown in the figures, that they are wall-mounted. For this purpose, suitable hooks are attached to the wall – possibly even before the screed is laid – and the housings 1, 2 are suspended from them. The distance between the housings 1, 2 after suspension from the finished floor can, as ultimately becomes clear from the 1 results, be very small.

Regardless of whether the housings 1, 2 are suspended from a building wall or not, it is furthermore preferably provided that they are connected to one another via at least one rail arranged horizontally (in particular on the rear side of the housings 1, 2). Particularly preferably, two rails are provided, one at the top and one at the bottom of the housing, so that a fixed distance between the housings 1, 2 can be established particularly easily.

In a manner known per se, it is furthermore particularly with reference to 1 It is provided that a hydraulic piping 3 is provided in at least one housing 1, 2. 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 is assigned 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, which is optionally formed (as shown) from at least two tanks 4.1, 4.2 or (not separately shown) from a tank that is at least twice as wide as it is deep.

This requirement makes it possible to completely pre-assemble the housings 1 and 2, including their internal technical equipment, and then to deliver them to the construction site or installation site as finished modules.

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

As continues from 1 visible ( 2 is not so clear with regard to the said piping due to pipe blinds), it is further preferably provided that the piping 3 has a pipe section running horizontally from one surface 1.1, 1.2, 2.1, 2.2 to the other.

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

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

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

In all cases, it is further provided that the depth of the housings 1, 2 is less than 350 mm, particularly preferably even less than 300 mm, i.e. the housings are constructed very flat, particularly 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 are cylindrical with a vertically oriented cylinder axis - which is particularly pressure-stable compared to an alternatively provided (see above), preferably cuboid-shaped tank. 1 is a solution with two tanks 4.1, 4.2, in 2 even a solution with four tanks is presented, although in 2 two tanks 4.1, 4.2 are arranged in a common housing.

In order to be able to provide a sufficient amount of warm drinking water, it is further provided that the drinking water storage tank 4 is designed to extend over at least three-quarters of the height of the housing 1, 2.

Regarding the aforementioned installations, 2 referred to.

According to this embodiment, it is preferably provided that at least a part of a heat pump 5.1, preferably the indoor unit of a heat pump, is arranged in one of the housings 1, 2. In order to be able to defrost any possible icing of the outdoor unit of the heat pump, it is further particularly preferably provided that the heat pump 5.1 is provided with a defrost 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 - there simply called buffer memory).

Furthermore, as in 2 As can be seen, it is preferably provided that a ventilation system 6, a battery power storage unit 7, an expansion tank 8, preferably and optionally a drinking water and/or heating circuit expansion tank, and an electric heater 5.3 for generating hot water, in particular hot water for a heating circuit, are arranged in one of the housings 1, 2. As is readily apparent, all of the aforementioned installations 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 storage unit 7.

Finally, in order to form a so-called installation rail, it is particularly preferred that a support device (not separately shown) for receiving the hydraulic piping 3 is arranged in the housing 1, 2.

Particularly preferably, the carrier device is provided in at least two housings 1, 2, preferably in all housings used.
