Description

Field of the invention

[0001] The invention relates to a particle foam insulation for a distribution bar with a heating / cooling circuit distribution system, which has a modular design, and to an insulation module designed therefor. In particular, the invention relates to an insulation for a distribution bar, which comprises horizontal pipe outlets for the supply and return lines as well as vertical pipe outlets to an assembly with a mixer and pump. Background of the invention

[0002] So-called distribution manifolds are used for hot and / or cold water distribution in buildings, particularly industrial buildings, office buildings, and apartment buildings. These manifolds, especially when used as intended, comprise horizontally arranged pipes for the supply and return lines. Vertically arranged pipes can be used to branch off and distribute the water to individual units, for example, to different floors, for heating, underfloor heating, hot water, etc.

[0003] In systems known from practice, for example, a unit with a pump and mixer is connected to the branches of the distribution bar, through which the water of the hot water circuit and / or cooling water circuit is distributed.

[0004] It goes without saying that such a distribution beam must be thermally insulated. For this purpose, insulation made of particle foam, particularly EPP, EPS, or other particle foam, can be used.

[0005] Since such an installation system with a distribution bar is modular in design, meaning that it can include different numbers of branches to the individual units, molded foam parts must be provided in different lengths and with different numbers of branches, or several insulations must be arranged one after the other along the distribution bar.

[0006] Providing particle foam moldings in different lengths is complex due to the various shapes required. However, if several insulation panels are placed one after the other over the distribution beam, additional insulation must usually be added, which may include, for example, manually processed, especially cut-to-size XPE foam. This is also complex.

[0007] Furthermore, such installation systems require different pipe diameters for the supply and return pipes, depending on the application. For insulation systems known from practice, insulation is therefore available that is adapted to the respective pipe diameter. This also requires the provision of a variety of different molded foam parts. Furthermore, if the manifold is modified, for example, to install a larger-diameter supply and return pipe, the insulation cannot be reused but must be replaced. This means, in particular, the larger elements that form the insulation casing must be replaced. Object of the invention

[0008] Against this background, the invention is based on the object of at least reducing the aforementioned disadvantages of the prior art. Summary of the invention

[0009] The object of the invention is already achieved by a distribution bar insulation and by an insulation module designed for the distribution bar insulation according to one of the independent claims.

[0010] Preferred embodiments and further developments of the invention can be found in the subject matter of the dependent claims, the description and the drawings.

[0011] According to a first aspect, the invention relates to a distribution bar insulation system. This system comprises a first insulation module with at least two horizontal pipe outlets and at least two vertical pipe outlets. "Horizontal" and "vertical" refer to the intended use.

[0012] In the sense of the invention, the first insulation module serves for the thermal insulation of the distribution bar in the area of ​​a branch and for this purpose comprises at least two vertical pipe outlets.

[0013] Furthermore, the distribution bar insulation comprises at least a second insulation module with at least two horizontal pipe outlets or passages.

[0014] The second insulation module can also comprise at least two vertical pipe outlets, provided it is used for insulating the distribution bar in the area of ​​another branch. In particular, the first and second insulation modules can be identically designed.

[0015] According to another embodiment, the second insulation module can also be designed as a connecting module without vertical pipe outlets for two additional insulation modules. Furthermore, the second insulation module can serve as the end piece of the distribution bar insulation.

[0016] The first and second insulation modules are formed from at least two, in particular exactly two, housing parts made of a particle foam, which can be connected via a plug-in connection. In particular, a rigid particle foam is used.

[0017] These housing parts, in particular the housing halves, can be easily plugged together, in particular by means of a tongue and groove connection.

[0018] According to the invention, at least the horizontal pipe outlets comprise a replaceable insert with a pipe leadthrough.

[0019] The insert is preferably also made of a particle foam, in particular of the same material as the housing parts of the insulation modules.

[0020] The interchangeable insert allows the manifold insulation to be adapted to different pipe diameters. In particular, at least two, preferably three, inserts can be provided with a pipe penetration of a different diameter, e.g., between DN80 and DN150.

[0021] Furthermore, insulation modules with pipe outlets in special sizes can also be easily provided. All that is required is a mold for the tool used to produce the insert in the special size. However, there is no need to modify the tool used to produce the housing halves of the insulation modules.

[0022] On the one hand, insulation modules can be provided with an identically designed housing, in which only the insert required for the respective pipe diameter needs to be mounted.

[0023] Furthermore, if the installation is converted to a different pipe diameter, the existing distribution bar insulation can be reused except for the insert.

[0024] Preferably, the insulation modules can also be connected to one another by means of a plug connection.

[0025] In particular, the insulation modules can be connected to each other via a radially circumferential tongue and groove connection.

[0026] In particular, it is provided that insulation modules with vertical pipe outlets are connected to a connecting module which encompasses the insulation module with the vertical pipe outlets in the connection area.

[0027] Preferably, the distribution bar insulation is designed such that the distribution bar is enclosed in an airtight manner.

[0028] The manifold bar insulation is preferably made of expanded polypropylene. Thanks to the plug-in connection of the insulation modules and the insert used, additional sealing, such as the insertion of a hardening foam, is generally unnecessary, especially when using EPP. Rather, the connection itself provides sufficient sealing, so that there are no openings in the insulation through which air could circulate. Only for the pipes of a cooling circuit may additional insulation be required, which is in direct contact with the pipe to prevent the formation of condensation on the pipe wall.

[0029] According to one embodiment of the invention, the insert is formed from two halves. In particular, one half of the insert, for example, which assumes a circumferential angle of 180°, can be inserted into the groove of a vertically extending wall of the insulation module.

[0030] This makes the insert easy to install.

[0031] The insert can in particular be designed as a ring segment, at least in sections.

[0032] Furthermore, according to one embodiment of the invention, the insert comprises an extension serving to center the insert, which extension, in the mounted state, sits in a preferably complementarily formed recess in the wall of the insulation module.

[0033] This extension can include an undercut, relative to the insertion direction, through which the insert is secured in the wall. When the insert is inserted, the vertically extending wall of the insulation module expands and contracts again when fully inserted.

[0034] In a further development of the invention, the halves of the first and / or second insulation module, in particular the halves of the insulation module designed as a connecting module, can be mechanically connected to one another in addition to the plug-in connection. In particular, the housing halves of the connecting module can each comprise extensions arranged, preferably at the top and bottom, which are connected by means of a snap-in closure. The use of other quick-release fasteners, e.g., expansion dowels or screws, is also conceivable.

[0035] In particular, when the connecting module encompasses an adjacent insulation module, the housing halves of the adjacent insulation module are also secured against unauthorized removal. In a preferred embodiment of the invention, the plug connection of the housing halves and / or the plug connection between two adjacent insulation modules is designed as a seal. As explained above, the use of EPP in a tongue and groove connection, in particular, can provide a connection that is sufficiently airtight, eliminating the need for additional sealing elements.

[0036] The plug connection can in particular comprise a spring which has a step or an offset.

[0037] In particular, an offset can cause the spring to twist when the parts are put together, which results in easier assembly and / or an improved sealing effect.

[0038] In a further development of the invention, a side wall of the distribution bar insulation, in particular a side wall of the connection module, can be closed by means of an insertable cover.

[0039] In particular, the cover can be inserted into a circumferential groove of the connection module, which otherwise encompasses a spring of another insulation module.

[0040] This makes it easy to seal the manifold bar insulation on a side where there are no pipe outlets.

[0041] In a further development of the invention, a third insulation module is placed on top of the first and / or second insulation module, which is designed as a device housing, in particular as a housing for a water distributor and / or a pump. This can be pushed onto a base of the insulation module, in particular via a rail system.

[0042] For this purpose, the insulation module used in the area of ​​a branch can in particular comprise a base onto which a connecting plate with pipe penetrations is placed, in particular pushed, onto.

[0043] Preferably, a housing of the third insulation module is designed for different pipe diameters. This housing can, in particular, have a foldable extension that acts as a positioning aid for a pipe. Depending on the particular pipe, the extension can be folded down, thus providing additional space for a thicker pipe.

[0044] According to a further aspect, the invention relates to a distribution bar insulation, which may in particular comprise one or more of the features described above.

[0045] The distribution bar insulation comprises a first insulation module with at least two horizontal pipe outlets and at least two vertical pipe outlets, as well as at least one second insulation module with at least two horizontal pipe outlets or passages. The first and second insulation modules are formed from at least two housing parts made of particle foam, which can be connected via a plug-in connection.

[0046] According to the invention, the first and second insulation modules can be connected to one another by means of a connecting module.

[0047] As described above, it is particularly provided that the connection module comprises only horizontal pipe penetrations and connects two insulation modules with vertical pipe outlets, in particular by encompassing them in the region of a plug connection.

[0048] Such a system with connection modules and insulation modules for a branch can be extended as required thanks to its modular design and can therefore be easily adapted to a modified installation of the distribution bar at a later date.

[0049] The invention further relates to an insulation module which is designed for the distribution bar insulation described above.

[0050] The insulation module can be designed in particular as an insulation module for a branch with vertical pipe outlets or as a connection module.

[0051] The invention particularly relates to a set comprising an insulation module with vertical pipe outlets and a connection module.

[0052] Furthermore, the invention relates to an arrangement with an insulation module and at least one connection module which is connected to the insulation module via a plug connection.

[0053] The invention further relates to a distribution bar which comprises the distribution bar insulation described above. Brief description of the drawings

[0055] Fig. 1 shows a perspective view of an exemplary embodiment of a distribution bar insulation 1.

[0056] The distribution beam insulation 1 is made of a particle foam, in particular of EPP, and comprises the pipe outlets 2 and 3 on one side. The pipe outlets 2 and 3 are arranged one above the other and serve to connect a flow and return line of a heat generator, for example a heat pump, via an installation with pipes (not shown).

[0057] In this embodiment, the water flowing through the distribution bar is branched off into the isolation modules 100, 100', and 100'' (via pipes not shown). The isolation modules 100, 100', and 100'' thus include vertical pipe outlets leading to the isolation modules 300 and 300', which are designed as housings for a device installation, for example, a water pump and mixer.

[0058] For this purpose, the insulation modules 100, 100', 100'' each comprise a base 110 arranged at the top, onto which the insulation module 300, 300' designed as a device housing is placed, in particular pushed.

[0059] The insulation modules 100, 100', 100'' are connected to each other via connecting modules 200, which are also made of particle foam. The connecting modules 200 also serve as end pieces for the distribution bar insulation 1.

[0060] For this purpose, the connecting modules 200 are formed from a front housing half 201a and a rear housing half 201b, which can be plugged into one another and thereby encompass the insulation modules 100, 100', 100'' at the edges. The housing halves 201a, 201b comprise a tongue and groove connection and are plugged together.

[0061] In addition to the plug connection, the connection modules 200 further comprise extensions 202a, 202b at the top and bottom, by means of which the housing halves 201a, 201b are mechanically connected to one another, for example by means of expansion dowels or screws 4, in addition to the plug connection.

[0062] The housing halves 201a, 201b encompass the insulation modules 100, 100', and 100'' in the connection area. This additional mechanical connection prevents accidental disassembly of the insulation modules 100, 100', and 100''.

[0063] In this exemplary embodiment, the insulation modules 100, 100', 100'' and the connection modules 200 have a substantially identical external cross-section. In particular, this cross-section can be elongated, particularly in the form of a slot. The connection modules 200 are shorter than the insulation modules 100, 100', 100''; in particular, they can be 0.3 to 0.5 times the length of the insulation modules 100, 100', 100''.

[0064] The isolation modules 100, 100', 100'', and / or connecting modules 200 (excluding the extensions) can have a height-to-width ratio between 1.6 and 2.0. The isolation modules 100, 100', 100'', and / or connecting modules 200 can be between 60 and 90 cm high and / or between 30 and 50 cm wide.

[0065] Fig. Figure 2 is a perspective view of the distribution bar insulation 1, wherein the front housing halves (101a, see Fig. 1, Fig. 201a) of the insulation modules 100, 200 have been removed. The insulation modules 100 comprise two opposite edge walls 103, each with two pipe outlets. The insulation modules (300, 300') for the pump / mixer assemblies are hidden.

[0066] The connecting modules 200 comprise a single vertical wall 203 with two horizontal pipe penetrations, wherein in this illustration a replaceable insert 10 is inserted into one of the pipe penetrations.

[0067] On one side, the wall 203 with the insert 10 serves as a pipe outlet for the distribution beam insulation 1.

[0068] On the opposite side, the insulation module 200, designed as a connecting module or terminating module, is closed with an inserted cover 200 and thus insulated.

[0069] The housing halves 101b (and 101a) of the insulation modules 100 form a base 110, onto which a connecting plate 301 for the insulation module 300 designed as a device housing can be placed, in particular plugged.

[0070] If the pump / mixer assembly includes shut-off valves, a connecting segment 302 can be used instead of the connecting plate 301. This connecting segment can be attached like the connecting plate 301 and forms a housing for the shut-off valves. The pump / mixer assembly is positioned higher than the assembly without shut-off valves.

[0071] Furthermore, there is a horizontal wall 102 in the insulation modules 100, which divides the respective insulation module 100 into two chambers and thus provides insulation between the flow and return.

[0072] In this embodiment, the wall 102 is formed from two halves, which are part of the housing halves 101b (and 101a). The halves of the horizontal wall 102 are also connected via a plug-in connection. The part of the horizontal wall 102 shown here, which is formed by the rear housing half 101b, engages a complementarily shaped wall section of the front housing half (101a).

[0073] At the bottom, the insulation modules 100 comprise at least one passage for a floor mount or a stand, which can be closed with a cover 30 if a floor mount is not mounted.

[0074] Preferably, the closure cover is inserted into a groove that extends horizontally through both housing halves 101b (101a).

[0075] Fig. 3 shows a perspective detailed view of the connection area of ​​the rear housing halves of the connection module 200 with the isolation module 100.

[0076] The vertical wall 203 of the insulation module 200 comprises circular segment-shaped passages with a groove 204 into which an exchangeable insert 10 is inserted for adaptation to the respective pipe diameter.

[0077] The frontal vertical inner circumferential groove 207 serves either for connection to an insulation module 100 or for inserting a cover (see Fig. 12)

[0078] Such an insert 10 is also inserted into a groove 104 in the vertical wall 103 of the insulation module 100.

[0079] Fig. Figure 4 is a perspective view of such an insert 10. The insert 10 is preferably made of particle foam, in particular EPP. It is formed by a ring segment, in particular a semicircle, with a pipe leadthrough 11.

[0080] Furthermore, the insert 10 comprises an extension 12 which, when mounted, is in the Fig. 3 shown recess 205 of the vertical wall 203.

[0081] The extension 12 comprises an undercut by which the extension 12 is locked or clamped in the recess 205 in the insertion direction.

[0082] The pipe outlets or pipe feedthroughs provided by the inserts 10 can be easily installed, since the insert 10 only needs to be inserted into the front housing halves and the rear housing halves.

[0083] As in Fig. 5a and Fig. As shown in Figure 5b, different inserts 10 are provided for different pipe diameters, which can be easily exchanged.

[0084] Fig. 6 is a detailed view of the connection area between the connection module 200 and an isolation module 100.

[0085] To provide an axial connection, the connection module 200 comprises springs 206 on the front side, which engage in a circumferential inner vertical groove 105 of the insulation module.

[0086] Behind the spring 206, the connection module 200 comprises a radially extending groove 207, into which a spring 111 of the insulation module 100 engages.

[0087] Thus, the connecting module 200 engages around the spring 111 of the connecting module at the front.

[0088] The end spring 206 of the isolation module 200 includes an offset or step, which facilitates assembly and improves the sealing effect.

[0089] The groove 208 extending horizontally in the axial direction serves for the plug connection with the front housing half.

[0090] Fig. Figure 7 is a detailed view of the connection area between the isolation module 100, the branch and the isolation module 300 designed as a housing.

[0091] The insulation module 300, designed as a housing, is mounted on the base 110 of the insulation module 100 with the connecting plate 301. A tongue and groove connection is also used for this purpose.

[0092] The spring 307 of the connecting plate 301 expands and is guided in the groove 112 of the base 110, which forms an undercut.

[0093] A rail system is provided for attaching the isolation module 300, which is designed as a device housing. First, the two halves of the connecting plate are pushed onto the base 110 from the front and rear.

[0094] The connecting segment (302) is mounted according to the connecting plate 301.

[0095] Fig. 8 is a perspective view of a connection module 200 with the pipe penetrations or pipe outlets 2 and 3.

[0096] As shown in the top view of the front side according to Fig. As shown in Figure 9, replaceable inserts 10 can be inserted into the pipe penetrations.

[0097] It is further shown that the front housing half 201a of the connection module 200 has a longitudinally extending spring 209 which engages in a complementarily formed groove 208 of the rear housing half 201b.

[0098] This allows the front housing half 201a to be easily plugged on.

[0099] Fig. 10 is a perspective view of the branch isolation module 100.

[0100] This includes the pipe outlets 2 and 3. Likewise, the front housing half 101a includes a spring 109 extending horizontally along the housing, which is inserted into a horizontal groove 108 of the rear housing half 101b.

[0101] The connecting plate 301 with the pipe bushings 303a and 303b is pushed onto the base 110.

[0102] The connecting plate 301 is preferably divided into two parts and can be pulled apart in the area of ​​the pipe penetrations 303a and 303b. The segments of the connecting plate 301 can preferably be plugged together using a tongue and groove connection.

[0103] Fig. 11 is an exploded view of the components of the isolation module 100, which includes the housing halves 101a and 101b, wherein a front base portion 211a is formed by the front housing half 101a and a rear base portion 211b of the base is formed by the rear housing half 101b.

[0104] Either the halves of the connecting plate 301 or the halves of the connecting segment 302 are pushed onto the base (110) thus formed.

[0105] The connecting plate 301 can be provided with different sized passages for the vertical pipes to adapt to different pipe diameters.

[0106] If no device assembly is mounted above the insulation module 100, the vertical pipe outlets of the insulation module 100 can be closed with a preferably inserted closure cover 30.

[0107] Preferably, this is the same cover 30 as is used to close the openings for the feet (see Fig. 2) is used.

[0108] Fig. 12 is a perspective view of the connecting module 200 used as an end piece.

[0109] If this is not used for pipe outlets, a cover 20 with a circumferential spring 21 is inserted into the groove 207, which otherwise serves to connect to another insulation module.

[0110] Fig. 13 is a perspective view of the back of the cover 20.

[0111] Referring to Fig. 14, another aspect of the adaptation of the insulation module 300, which is designed as a device housing, to different pipe diameters will be explained in more detail.

[0112] The housing is placed on the connecting plate 301 sitting on the base 110 and comprises, in particular in the rear housing half 305, vertical pipe passages 304 which lead to the pipe passages 2, 3.

[0113] Extensions 306 extend into these pipe penetrations 304. The extensions 306 can be bent or clipped off and thus serve to precisely position the pipe within the pipe penetration 304, depending on the outer diameter of the respective pipe.
