Description

The present invention relates to a connection device for a heat generator in technical building equipment, a heat generator arrangement in technical building equipment and a method for connecting a heat generator, in particular a heat pump, to technical building equipment.

In practice, when piping heat generators in technical building equipment, such as water heaters, water storage tanks, gas boilers, condensing boilers, heat pumps that use different primary energies (air, water, earth, wind and solar energy), and other drinking water heaters or boilers ( with/without storage, heat exchanger/flow principle) every necessary individual connection, supply and disposal line (e.g. heating flow line, heating return line, hot water circulation line, hot water line and cold water line) as well as any condensate, dripping water and/or wastewater line connected to the heat generator, insulated (according to DIN 1988-200/EN 806-2/GEG), soundproofed (according to DIN 4109/VDI 4100), decoupled from the structure and incorporated individually into a floor structure or placed as an attachment on a floor surface. To do this, the relevant pipe sections of the respective line must be installed separately in or under the floor insulation, impact sound insulation, if necessary in or under the underfloor heating and screed leveling layer, cut, leveled and adjusted in height. This assembly is very time and labor intensive. In addition, a load distribution layer may be required to be installed separately below the area of the heat generator to be connected to absorb the weight of the heat generator.

This is where the present invention comes in, which is based on the object of providing a possibility for connecting a heat generator in technical building equipment, through which the disadvantages of the prior art can be at least partially overcome. In particular, connecting a heat generator is intended to be significantly simplified by the connection device according to the invention. In addition, the integration of a heat generator into an existing or into a new screed layer/screed structure height can be considerably simplified. It should also be possible to improve the acoustic emission values when operating the heat generator. Furthermore, the object of the present invention is to provide a heat generator arrangement for technical building equipment comprising a connection device according to the invention and a simplifying method for connecting a heat generator to technical building equipment.

These and other tasks are achieved according to the invention by a connection device with the features of claim 1, by a heat generator arrangement with the features of claim 16 and by a method with the features of claim 18. Preferred embodiments of the present invention are described in the dependent claims.

According to the present invention, it was recognized that the process of connecting a heat generator, in particular a heat pump, to technical building equipment can be significantly simplified in that the pipe sections that are to be connected to the heat generator and which can preferably be assigned to a heat consumer are already are integrated into a connection device onto which the heat generator can then be placed. According to the invention, this is achieved in that at least two corresponding pipe sections are at least partially accommodated in an insulation block made of thermally insulating material, in particular made of foamed polymer material, preferably made of a polyurethane foam. The length of the pipe sections is selected such that the connecting ends of the pipe sections are arranged to be freely accessible with respect to the insulation block. This makes it easy to connect the heat generator to the technical building equipment. The connection device according to the invention is simply placed on the surface at the desired position in the house and, if necessary, attached to it, in particular glued or screwed on. The heat generator can then be placed on the connection device according to the invention. The pipe sections can then be connected to corresponding connecting elements of the heat generator without additional and time-consuming measurement and with a precise fit, in particular by screw or press connections. Due to the integration of the pipe sections into the connection device according to the invention, it is no longer necessary to insulate these pipe sections individually and to provide them individually with impact sound insulation or a complex fastening. These functions are achieved by the thermally insulating material of the connection device according to the invention accepted. In addition, it is no longer necessary to cast appropriate leveling compounds around the pipe sections required for connection. This makes connecting the heat generator to the technical building equipment or the house installation system considerably easier by using the connection device according to the invention.

Accordingly, the present invention lies in the provision of a connection device for a heat generator in technical building equipment with an insulation block made of thermally insulating material and with at least two pipe sections which are at least partially arranged in the thermally insulating material of the insulation block, with connecting ends of the pipe sections with respect to the insulation block are freely accessible. In addition, the present invention lies in a heat generator arrangement of technical building equipment with a heat generator and a connection device according to the invention, the heat generator being designed as a water heater, water storage tank, gas boiler, condensing boiler, heat pump, drinking water heater or boiler, and wherein the at least two pipe sections are each connected to a line of the heat generator from the group comprising heating flow line, heating return line, hot water line, cold water line, hot water circulation line, condensate line, drip water drain line and wastewater line. Ultimately, the present invention also relates to a method for connecting a heat generator to technical building equipment, which includes the steps (a) of setting up a connection device according to the invention on a surface at the desired position for the heat generator; (b) placing the heat generator on the connection device; and (c) connecting one of the connection ends of the pipe sections to a corresponding connection of the heat generator.

As used herein, the term “technical building equipment” refers to all technical equipment installed in a building and/or permanently connected to it, as well as technical equipment in outdoor facilities that serve the functional use of buildings. This includes all systems and facilities permanently installed in the building that are necessary for use and living and/or that increase living comfort. Technical building equipment includes, for example, systems for building heating and drinking water heating, ventilation systems, air conditioning systems, systems for the use of renewable energies (e.g. solar thermal energy, geothermal energy, photovoltaics, biomass), water and wastewater supply systems, power systems and fire extinguishing systems, but are not limited to those mentioned.

With regard to the connection block according to the invention, it can be advantageous if the insulation block is made of a foamed material or a fiber material. These materials have proven to be sufficiently stable with good thermal insulation properties. It is preferred if the insulation block is made of a polymer material, in particular a foamed polymer material.

It can also be advantageous if at least one connection end of the pipe sections protrudes from the insulation block, preferably all connection ends of the pipe sections protrude from the insulation block. In this way, the connection end of the pipe sections with the respective connections of the heat generator can be further simplified.

It can also be advantageous if the connection device has at least four pipe sections which are at least partially arranged in the thermally insulating material of the insulation block. The higher the proportion of pipe sections accommodated in the insulating block in the total number of required individual connections to the heat generator, the more simplified the connection process of the heat generator is. It is preferred if one pipe section is designed to connect the heating flow line, the heating return line, the hot water line and the cold water line to the heat generator.

Additionally or alternatively, it can be helpful if the connection block comprises at least one further pipe section, which is at least partially arranged in the thermally insulating material of the insulation block and wherein the further pipe section is used to connect the hot water circulation line, the condensate and drip water drain line and/or the wastewater line is trained. The integration of further pipe sections into the thermally insulating material of the connection block according to the invention further simplifies the connection of the heat generator to the technical building equipment.

It may also be preferred if the pipe sections are arranged adjacent to one another and/or in a common plane.

It can also be advantageous if the insulation block has a substantially cuboid structure. A cuboid structure of the insulation block ensures a stable application of the connection device according to the invention to a corresponding surface. In addition, the heat generator can be easily attached to such a structure without additional measures.

It can also be useful if the thermally insulating material has a thickness in the range from 4.0 cm to 20.0 cm, in particular from 5.0 cm to 15.0 cm. Such a material thickness of the thermally insulating material offers an improvement in the insulation and impact sound insulation properties required in the TGA according to DIN 1988 / EN 806 / VDI / DVGW / GEG.

In preferred embodiments of the connection device according to the invention, the thermally insulating material of the insulation block has a thermal conductivity coefficient of at most 0.15 W/(m*K), in particular at most 0.10 W/(m*K) and particularly preferably at most 0 .05 W/(m*K).

Due to good insulation and impact sound insulation properties, the use of polyurethane foam as the thermally insulating material has also proven to be particularly advantageous.

In preferred embodiments of the connection device according to the invention, the connection ends of at least one of the pipe sections, preferably of all pipe sections, are arranged on two opposite sides of the insulation block. Particularly preferably, the ends of at least one of the pipe sections, preferably of all pipe sections, protrude from the thermally insulating material on two opposite sides of the insulation block. This version of the connection device according to the invention is particularly easy to manufacture and enables a low material thickness of the thermally insulating material of the insulation block and thus low installation heights. In addition, the ends of the pipe sections are easily accessible and well fixed surrounded by the thermally insulating material, which simplifies the process of connecting the pipe sections to corresponding connections of the heat generator in a time-saving manner without additional fitting. In alternative embodiments of the connection device according to the invention, the connection ends of at least one of the pipe sections, preferably of all pipe sections, are on two mutually adjacent sides of the insulation block arranged. Particularly preferably, the connection ends of at least one of the pipe sections, preferably of all pipe sections, protrude from the thermally insulating material on two adjacent sides of the insulation block. Such a structure of the connection device according to the invention makes it possible for the pipe sections running in the insulation block to have a bend of approximately 90° inside the thermally insulating material. Other bending angles of the pipe sections and/or the at least one further pipe section, for example approximately 45°, are also possible according to the invention. As a result, the pipe sections that run horizontally under the heat generator over a large part of their length already protrude from the thermally insulating material at a defined point and at a defined exit angle in the direction of the connecting elements of the heat generator, which further facilitates their connection to the connecting elements of the heat generator.

It can also be advantageous if a support surface for the heat generator is formed on one side of the insulation block. Such an installation surface of the insulation block ensures that the heat generator stands securely. In particularly preferred embodiments of the connection device according to the invention, the installation surface is formed by a load distribution layer. The load distribution layer has a higher strength than the thermally insulating material. This load distribution layer increases the load capacity of the connection device according to the invention, so that the heat generator can be positioned on the connection device according to the invention to withstand high static loads over a period of use lasting several years.

According to a special embodiment, the connection device according to the invention sits in a recess in the screed. This has the advantage that the heat generator can be installed before the screed is installed. This means that the heating of the screed can be started quickly and safely. It is not necessary for the heat generator to be installed immediately as soon as the screed can be walked on. The close coordination of the trades can be reduced accordingly.

It can also prove to be advantageous if one connection end of the pipe sections is arranged in a plane parallel to the installation surface, and the other of the connection ends of the pipe sections is aligned perpendicular to the installation surface, and in particular leads through the installation surface or is arranged adjacent to the installation surface.

It can also be helpful if at least one through hole is formed in the insulation block, preferably at least two through holes are formed, the through hole or holes being in particular aligned at least substantially perpendicular to the pipe sections. This measure also serves to simplify the connection process of the heat generator.

It can also be advantageous if the heat generator is designed as a water heater, water storage tank, gas boiler, condensing boiler, heat pump, drinking water heater or boiler. A heat pump as a heat generator is particularly preferred according to the present invention.

According to the present invention, corresponding sections of plastic pipes, solid plastic pipes, preferably made of polyethylene (PE, in particular PE 100 and PE-RT (polyethylene with increased temperature resistance)), crosslinked polyethylene (PE-X, in particular PE-Xa) come as pipe sections and as further pipe sections , PE-Xb and PE-Xc), polypropylene (especially random polypropylene PP-R) and polybutylene (PB); as well as plastic composite pipes, preferably with layers of polyethylene (PE, in particular PE 100 and PE-RT), cross-linked polyethylene (PE-X, in particular PE-Xa, PE-Xb and PE-Xc), polypropylene (in particular statistical polypropylene PP- R), and/or polybutylene (PB) as well as metal-plastic composite pipes (MKV pipes) are used.

According to the present invention, it is preferred that the pipe sections and/or the further pipe sections are each accommodated in the thermally insulating material of the insulation block over more than 50%, in particular more than 70% and preferably over more than 80%, of their length.

The features mentioned in relation to the connection device according to the invention and the advantages described apply accordingly in relation to the heat generator arrangement according to the invention and the method according to the invention for connecting a heat generator.

Furthermore, with regard to the connection device according to the invention, it is fundamentally important to note that it can be erected, set up, laid down, inserted, integrated in an integrated manner or glued on in a free-standing, vertical and horizontal position.

With regard to the heat generator arrangement according to the invention, it can be useful if at least one of the lines outside the insulation block has a single line insulation, which is designed in particular up to the insulation block.

With regard to the method according to the invention, it may prove helpful if it further comprises the step of at least partially isolating the sections of the pipe sections and/or the at least one further pipe section which are located outside the insulation block.

Additionally or alternatively, it may also be preferred if the method additionally includes the step of applying a load distribution layer to the connection block.

The connection block according to the invention can also be produced line by line or layer by layer using a line-building or layer-building manufacturing process (e.g. 3D printing). However, the pipe sections are preferably introduced into a corresponding shape and the thermally insulating material is foamed around the pipe sections to form the connection device according to the invention.

In Fig. 1a is an embodiment of a connection device 1 according to the invention for a heat generator 2 (cf. Fig. 3 ) in a technical building equipment, in particular a house installation, shown schematically in a top view, the heat generator 2 preferably being designed as a heat pump. The connection block 1 according to the invention comprises an insulation block 3 made of thermally insulating material, in particular made of a foamed polymer material. Four pipe sections 4 to 7 and another pipe section 8 are introduced into the insulation block 3, which in the illustrated embodiment is designed as a polyurethane foam. The pipe sections 4 to 7 and the further pipe section 8 have the same length in the embodiment shown. While the four pipe sections 4 to 7 also have the same external pipe diameter, the further pipe section 8 has a smaller external pipe diameter. Of the four pipe sections 4 to 7, one is designed to connect the heating flow line, the heating return line, the hot water line and the cold water line to the heat generator 2. In contrast, the further pipe section 8 is designed to connect the hot water circulation line. In alternative embodiments of the connection block 1 according to the invention, the further pipe section 8 can also be used to connect the condensate and drip water drain pipe and/or the waste water pipe. In addition, it is also possible for more than one further pipe section 8 to be included in the thermally insulating material of the insulation block 3 of the connection device 1 according to the invention, which can be used to connect the lines mentioned.

The pipe sections 4 to 7 and the further pipe section 8 run in the in Fig. 1a illustrated embodiment essentially parallel and in relation to a base area of the connection device 1 according to the invention essentially at the same level through the thermally insulating material 3, which in the embodiment shown essentially assumes a cuboid external shape. The course of the pipe sections 4 to 7 in the insulation block 3 is in Fig. 1a and Fig. 1b , in which the in Fig. 1a shown connection device 1 according to the invention is shown in a schematic side view, indicated by dashed lines. The ends of the pipe sections 4 to 7 and the further pipe section 8 are arranged to be freely accessible. In the illustrated embodiment of the connection device 1 according to the invention protrude these free ends on two opposite sides beyond the thermally insulating material of the insulation block 3. As a result, these free ends are freely accessible and can easily be used for connection to corresponding connections of the heat generator 2. This connection can also be made indirectly via appropriate fittings, for example via T-pieces, and if necessary via short pipe sections.

In the embodiment shown, the base of the cuboid made of thermally insulating material is essentially rectangular with edge lengths of approximately 155 cm and 55 cm. The thickness of the thermally insulating material is in Fig. 1a shown embodiment about 7 cm.

For fastening to a surface, the insulation block 3 has six through holes 9 through which the fastening means to be used for fastening, in particular screws, can be guided.

For transport to the installation site, the free ends of the pipe sections 4 to 7 and the further pipe section 8 can be closed with removable caps in order to prevent contamination from penetrating into the pipe sections 4 to 7 and the further pipe section 8 and to protect their free ends from damage protect.

A further embodiment of the connection device 1 according to the invention for a heat generator 2 in technical building equipment is shown in Fig. 2a shown schematically in a top view. The explanations for the embodiment according to Fig. 1a and Fig. 1b apply with respect to the embodiment according to Fig. 2a and Fig. 2b , in which the in Fig. 2a Connection block 1 shown is shown in a schematic side view, unless otherwise explicitly stated. Identical reference numbers stand for identical elements.

Also according to this embodiment, the connection device 1 according to the invention comprises a cuboid made of thermally insulating material 3, in particular made of a polyurethane foam, into which, in the embodiment shown, four pipe sections 4 to 7 and another pipe section 8 are introduced, which also have the same length according to this embodiment own. Also according to this embodiment of the present invention, of the four pipeline sections 4 to 7, the have the same external pipe diameter, but in alternative embodiments can also have different pipe diameters, one in each case designed to connect the heating flow line, the heating return line, the hot water pipe and the cold water pipe to the heat generator 2, while the further pipe section 8, which is smaller than the pipe sections 4 to 7 Pipe outside diameter has, is designed to connect the hot water circulation line. In alternative embodiments of the connection device 1 according to the invention, the further pipe section 8 can also be used to connect other pipes, for example the condensate and drip water drain pipe and/or the waste water pipe, or more than one further pipe section 8 can be integrated into the thermally insulating material for the purposes mentioned be.

The pipe sections 4 to 7 and the further pipe section 8 run in the in Fig. 2a illustrated embodiment over a wide range of its length essentially parallel and with respect to a base area of the connection device 1 according to the invention essentially at the same level through the thermally insulating material. In the area of the side of the cuboid made of thermally insulating material, which is opposite the side of the entry of the pipe sections 4 to 7 and the further pipe sections 8 into the insulating block 3, the pipe sections 4 to 7 and the further pipe section 8 have a bend of approximately 90 ° . The course of the pipe sections 4 to 7 in the thermally insulating material is in Fig. 2a and Fig. 2b indicated by dashed lines, where Fig. 2b in the Fig. 2a illustrated connection device 1 according to the invention shows in a schematic side view.

The ends of the pipe sections 4 to 7 and the further pipe section 8 are located according to FIG Fig. 2a and Fig. 2b shown embodiment of the connection block 1 according to the invention. In the in Fig. 2a and Fig. 2b In the illustrated embodiment of the connection box 1 according to the invention, these free ends protrude beyond the thermally insulating material on two adjacent sides of the cuboid. As a result, these free ends are freely accessible and can be used for connection to corresponding connection elements of the heat generator 2, whereby they already point in the direction of the connection elements of the heat generator 2 due to the respective 90 ° bends. This connection can also be done indirectly via appropriate fittings, for example via T-pieces.

In the embodiment shown, the base area is essentially rectangular with edge lengths of approximately 95 cm and 56 cm. The thickness of the thermally insulating material is in Fig. 1a shown embodiment about 12 cm. Due to the higher material thickness of the thermally insulating material, it is possible for the 90° bends of the pipe sections 4 to 7 and the further pipe section 8 to be accommodated in the thermally insulating material.

On the side of the cuboid on which the pipe sections 4 to 7 and the further pipe section 8 emerge from the thermally insulating material, the connecting device 1 according to the invention has a mounting surface 10. This installation surface 10 is essentially flat and therefore particularly suitable for setting up the heat generator 2. In particularly preferred embodiments, a load distribution layer 11 can be applied to the thermally insulating material in the area of the installation surface 10. A corresponding metal sheet has proven to be particularly suitable as the load distribution layer 11.

For attachment to the substrate, the insulating block 3 in the embodiment according to Fig. 2a and Fig. 2b Four through holes are introduced through which the fasteners to be used for fastening, in particular screws, can be guided.

In principle, the connection device 1 according to the invention can be erected, set up, laid down, inserted, integrated or glued in a free-standing, vertical or horizontal position.

Fig. 3 is a schematic representation of a heat generator arrangement 20 according to the invention, which is in Fig. 2a and Fig. 2b shown connection device 1 according to the invention and a heat generator 2 includes. Accordingly shows Fig. 3 schematically an installation situation of a heat generator 2 in a technical building equipment using the in Fig. 2a and Fig. 2b shown connection device 1 according to the invention, on the footprint 10 of which a load distribution layer 11 is applied. The heat generator 2 is placed on this load distribution layer 11.

To connect the heat generator 2, the connection device 1 according to the invention is first placed in the desired position on a corresponding surface and fastened to the surface using screws that are guided through the through holes 9. Then the load distribution layer 11, designed as a metal sheet, is placed on the installation surface 10 of the thermal insulating material applied. The heat generator 2 is placed on this load distribution layer 11. The ends of the pipe sections 4 to 7 and the further pipe section 8 protruding from the installation surface 10 are connected to the corresponding connecting elements of the heat generator 2 via corresponding fittings 12 and, if necessary, additional pipe sections. As fittings 12 are in Fig. 3 T-pieces are shown, the free connections of which are each connected to pipe sections 13 of the corresponding circulation lines of the technical building equipment. These pipe sections 13 can be covered in sections with appropriate insulation 14. On the other hand, it is no longer necessary to insulate the pipe sections 4 to 7 and the further pipe section 8 in the area of the thermally insulating material. Likewise, the pipe sections 4 to 7 and the further pipe section 8 do not need to be cast with appropriate leveling compounds in this area. This significantly simplifies the process of connecting the heat generator 2 to the technical building equipment. The now still free ends of the pipe sections 4 to 7 and the further pipe section 8 are also connected to the corresponding circulation pipes of the technical building equipment, in which all the components required for its operation, such as mixers, pumps, hot water tanks, valves, tapping points, heat consumers (radiators , pipes from underfloor heating and the like) and possibly also expansion vessels. Finally, a layer of screed is applied to the subsurface, into which the various pipe sections in the subsurface area are accommodated. The connection device can sit in a recess in the screed. Optionally, the connection device 1 according to the invention can partially protrude from the screed layer, so that it functions as a platform, in particular a boiler platform.

The present invention has been described by way of example with reference to the embodiments of the present invention shown in the figures. It is understood that the present invention is not limited to the embodiments shown in the figures, but the scope of the present invention emerges from the appended claims.
