Description

The The invention relates to a connection adapter with which a capillary tube mat for indoor air conditioning with a supply line fluid-tight and pressure-tight connectable, wherein the connection adapter forms a flow-through line section, one end of which is a weld connection with at least one welding surface a weldable Plastic forms.

such Connection adapters are known from the prior art and are used to fluidly capillary tube mats with supply lines to connect, by in the operation of a heating or coolant fluid is passed through the capillary tube mat.

capillary tube are used for example in Klimadeckencken to interiors, such as e.g. Office space or whole office floors, to air-condition. In contrast to classical air conditioners, which the Rooms with an air-conditioned airflow heat or cool, air-conditioning capillary tube mats arranged in climatic ceilings Interiors over their thermal Radiation and without the noise and wind draft generating airflow the classic air conditioning.

in the The capillary tube mats are operated by the heating or cooling fluid flows through. The heating or cooling fluid is from a heating or cooling fluid supply tempered, which connected to the capillary tube mats in a circuit is. The fluid circuit is closed by the supply lines, which at one end with the heating or cooling fluid supply and connected at the other end with one or more capillary tube mats are. The supply lines are usually on manifolds connected to the capillary tube mats. A capillary tube mat usually comprises at least two manifolds, between which a variety of parallel arranged capillary tubes runs. Commercially available capillary tube mats are made of thermally conductive, corrosion resistant and weldable Made of plastic. If the supply lines are also off a weldable one Plastic can be made this when installing in the cooling ceiling welded directly to the manifolds of the capillary tube mat.

The Personnel who install the capillary tube mats, however, often has little Knowledge in plastic welding. Furthermore is plastic welding while the installation of the capillary tube mats by the necessary heating and curing time too time consuming and the supply lines are partially off Materials made with the plastic of capillary tube mats not weldable are.

These reasons have led to the fact that connection adapters are provided on the capillary tube mats, with which the supply lines can be connected without welding to the capillary tube mat. A connection system for heating or cooling surface areas, which does not require welding, for example, in DE 101 11 863 A1 described. Another connector is in the DE 195 23 839 A1 disclosed. Other known connection adapters have a quick coupling, in which the supply line can be inserted. Alternatively, for example, connection adapters are used with connection elements for cutting ring connections.

adversely in the mentioned connection adapters the necessary large installation space by a relation to the Connecting diameter large outside diameter, which can lead to problems when installing the capillary tube mat. Furthermore you can high production costs of capillary tube mats and leakage problems be disadvantageous by the structurally complex connection adapter.

By the embodiment of the invention Press connection connection as a compression-resistant pipe socket, is the structurally simple connection adapter with respect to the State of the art lower production costs to produce. Because commercial Pressing elements, such as compression sleeves and sliding sleeves, can be used for pressing, also arise for the compound produced or the entire climate ceiling also reduced production costs.

Finally are with the connection adapter according to the invention designed capillary tube mats also on mounting-unfriendly places, such as. in ceiling mounting, by the compression technique easily connected. As assembly tools are e.g. Pressing tongs used, which are common in pipeline construction and already exist at many craft businesses. The relative small diameter of the pipe socket of the connection adapter according to the invention needed very little installation space.

Of the inventive connection adapter can by different, mutually independent, each for themselves advantageous Refinements will be further developed. On these configurations and the advantages associated with each of the embodiments briefly explained below.

So can the press connection port and the weld connection port are made of different ones Be made of materials. This has the advantage that the materials of press connection connection and welding connection connection independent of selected each other can be. The welding connection connection can be made from a good weldable Plastic, for example, the same plastic as the capillary tube mat formed be. The press-connection connection may be used to form the compression-resistant Pipe socket, for example made of a corrosion-resistant metal, such as. Brass, copper or stainless steel, or even a fiber-reinforced plastic be prepared. The corrosion-resistant material is a long Lifetime of the connection reached. Furthermore, in the connection adapter a layer of aluminum foil or epoxy resin be formed, oxygen-tight around the line section formed by the connection adapter embody.

Around a particularly stable and tensile in the axial direction connection between the welding connection connection and to achieve the press-connection connection, the press-connection connection a flange-shaped protruding outwards Holding base of the material of the welding connection connection is overmoulded. The welding connection connection For example, in a plastic injection molding around the support base the press connection port to be injected. Through the support base, formed as a circumferentially radially projecting flange is the press-connection port in the weld connection port anchored. additionally also gets through the overmolded weld joint connection a twisting of welding connection connection and press connection connection against each other prevented because of Weld connection and the press-connection terminal at their contact surfaces to each other be liable.

Alternatively, the press connection port on the pipe socket also radially outward have protruding projections extending in the circumferential direction, which the press connection in addition seal and secure against axial slipping. To the press connection connection in the installed state to further seal, the Pressverbindungsanschluss at least one circumferentially extending sealing element on the pipe socket exhibit. Naturally the press-connection connection can also other, to the axial or form radial forms suitable forms on the pipe socket.

In an advantageous embodiment can the welding connection connection as a plastic welding sleeve formed with at least one socket welding surface on the inner circumference be. This has the advantage that the cup-shaped plastic welding sleeve especially simply with the end of a plastic tube, e.g. of the manifold a capillary tube mat, can be welded. By the am Inner circumference formed socket welding surface, with the outer peripheral surface of the Plastic pipe welded is, creates a stable weld.

The plastic welding sleeve can be formed in a standardized form, for example according to DIN 16962 part 6 to 9 or according to the directive DVS 2208 Part 1 (Deutscher Verband für Schweißtechnik eV). The formation of the plastic welding sleeve in a standardized form has the advantage that both all the necessary tools for welding, such as heaters, are present, as well as that the plastic welding sleeve is dimensioned so suitable for standardized plastic pipes. Alternatively, the plastic welding sleeve can also be formed with a reduced insertion depth of the tube into the connecting element, eg 50% to 30% of the insertion depth specified in the standard. Nevertheless, to achieve a stable weld chen, the plastic welding sleeve with shortened insertion depth is welded to both the socket welding surface as well as at one end face with the capillary tube mat. For this purpose, both the at least one essentially radial sleeve welding surface and at least one essentially axial, end-side butt welding surface can be formed on the welding connection connection. The plastic welding sleeve with shortened insertion depth has a smaller axial extent.

In An advantageous development of the press-connection connection at its to the welding connection connection facing side coated with the material of the welding connection connection be. This has the advantage that the press-connection connection is relative to the welding connection connection is axially fixed. additionally is the butt weld of the Weld connection enlarged in the radial direction to the flow opening.

To provide a capillary tube mat with a cost-effective Connection to the supply lines can be produced, are the Connection adapter designed according to one of the above embodiments.

Further can in an advantageous development of the capillary tube mat a welding connection connection the connection adapter formed mat side and with the capillary tube mat welded fluid-tight be. Thus, the connection adapter already in the production the capillary tube mat without big Effort welded become. The unusual in pipe construction plastic welding is for Connection of the supply line at the installation site not necessary. In addition, can a press-connection terminal of the connection adapter formed on the supply side and be fluid-tight connectable to the supply line. So can the supply line with a usual in pipeline construction Pressing technology of, for example, pipeline construction companies connected become.

In An advantageous development of the invention Kapillarrohrmatte can each of the headers of the same material as a weld connection be made of the connection adapter. So are the headers particularly good with the connection adapter welded and a fluid-tight, pressure-resistant connection is guaranteed. Around the capillary tube mat structurally particularly simple to design, the connection adapters each welded to an axial end of the manifolds.

Further the invention also relates to a supply line for a commercially available capillary tube mat, with a heating or cooling liquid the capillary tube mat can be fed is, with a first end, which is connectable to a heating or cooling fluid supply, and a second end, at which one to the capillary tube mat connectable Connection adapter is arranged.

First, the general structure of a connection adapter according to the invention with reference to 1 described.

1 shows an exemplary embodiment of a connection adapter according to the invention 1 in a schematic partial sectional view. The connection adapter 1 includes a press-fitting connection 2 and a weld connection terminal 3 ,

The press-connection connection 2 is at the in 1 embodiment illustrated as a rotationally symmetrical hollow cylinder. A flow opening 4 runs in the axial direction of the press connection connection 2 with a substantially constant inner diameter D1. On the outer peripheral surface, the press-connection terminal 2 a chamfer 5 a cylindrical contact section 6 and on the side to the welding connection connection 3 a support base 7 on. The one between the chamfer 5 and the support base 7 trained contact section 6 indicates at the in 1 illustrated embodiment, a substantially circular cylindrical peripheral surface with an outer diameter D2.

The support base 7 is formed with a relation to the outer diameter D2 enlarged outer diameter D3. The support base 7 runs in the circumferential direction of the press connection connection 2 and is radially outward of the contact portion 6 in front. At the in 1 illustrated embodiment, the two side surfaces extend 8th of the support base 7 substantially perpendicular to the parallel peripheral surfaces of support base 7 and contact section 6 , The matt side surface 8th' at the same time forms the one axial end of the press connection connection 2 out. At the in 1 illustrated embodiment of the connection adapter according to the invention 1 is the axial length L1 of the contact section 6 larger than the length L2 of the flange-shaped support base 7 , The support base 7 has in its substantially cylindrical peripheral surface and in its side surface 8th' groove 30 on.

The welding connection connection 3 is about the one axial end of the press-connection terminal 2 and especially around the support base 7 trained around. At the in 1 illustrated embodiment of the connection adapter according to the invention 1 is the welding connection connection 3 rotationally symmetrical, with a substantially cylindrical outer surface 9 formed. The one axial end of the press connection port 2 ie the support base 7 and partly the contact section 6 are from the welding connection connection 3 essentially completely enclosed. Thus has a contact surface 10 of the welding connection connection 3 with the supply-side press-connection terminal 2 the same contour as the press-connection connection 2 so that the weld connection 3 into the grooves 30 protrudes. As in the supply-side press-connection connection 2 , is also in the welding connection connection 3 a flow opening 11 formed in the axial direction with the inner diameter D1. The flow opening 11 Aligns with the flow opening 4 so that no turbulence occurs when a fluid passes through the flow openings 4 . 11 flowing. The connection adapter 1 thus forms a line section 29 one end of which is the press-fitting connection 2 and the other end of the weld connection terminal 3 forms.

The welding connection connection 3 is at its from the press connection terminal 2 opposite end formed as a plastic weld sleeve. For this purpose, the inner diameter of the weld connection terminal expands 3 of the diameter D1 in the region of the flow opening 11 on a pot-shaped bag 12 with a larger diameter D4. The plastic welding sleeve is through the substantially cylindrical pocket 12 trained at the in 1 illustrated embodiment has a insertion depth T1. The pocket 12 has a butt welding surface extending transversely to the longitudinal axis 13 and a sleeve welding surface extending in the circumferential direction, parallel to the longitudinal axis 14 on. At the mat-side end face has the weld connection 3 Furthermore, an additional transverse to the longitudinal axis extending butt weld 15 on. The insertion depth T1 of the bag 12 is smaller than the distance of the side surface 8th' of the press connection terminal 2 from the frontal butt weld surface 15 of the welding connection connection 3 , so the retaining socket 7 not in the bag 12 protrudes, but of the material of the weld connection 3 coated or enclosed.

The welding connection connection 3 is at the in 1 embodiment shown formed from a plastic, at least at the welding surfaces 13 . 14 . 15 has weldable properties so that it is at the welding surfaces 13 . 14 . 15 liquefied under appropriate heat influence and can be welded to other plastic elements, such as a plastic pipe. The pocket 12 and the insertion depth T1 can be designed as a plastic welding sleeve for pipe joints according to DIN 16962 or DVS 2208 Part 1 (German Association for Welding). At the in 1 However, the insertion depth T1 is smaller, by about 60%, than designed in the standards mentioned.

At the in 1 illustrated embodiment of the connection adapter according to the invention 1 is the welding connection connection 3 using a plastic injection molding process around the retaining base 7 of the press connection terminal 2 sprayed around. So is a complete enclosure of the support base 7 through the one-piece welded joint connection 3 possible. Furthermore, through the injection molded weld connection 3 a substantially complete contact with the press-connection connection 2 ensures and any manufacturing tolerances of the press connection connection 2 are balanced individually. The contact surface 10 automatically adapts to the surface of the holding base during injection molding 7 and also protrudes into the grooves 30 completely into it. The grooves 30 into which the welding connection connection 3 is injected, increases the tightness of the connection and prevents twisting or axial displacement of the two terminals 2 . 3 to each other. Alternatively, the weld and the press connection ports 3 . 2 eg screwed or glued together. The welding connection connection 3 is like that around the support base 7 formed around that at least the largest part of the contact portion 6 of the press connection terminal 2 as a pipe socket 28 from the weld connection 3 protrudes. In this case, the length L3 of the pipe socket 28 greater than the axial length L4 of the weld connection terminal 3 ,

The press-connection connection 2 is made of a non-compressible material, such as brass, copper, a stainless steel or a fiber-reinforced plastic. In this context, compression-resistant means that the press-connection connection 2 and in particular as a pipe socket 28 trained part of that Weld connection 3 protrudes, radially acting from the outside forces, as they occur during compression of commercial compression sleeves. This compression will be discussed in more detail later. In the following, the use and installation of the connection adapter according to the invention will be described in more detail.

Alternatively to the in 1 illustrated embodiment, other embodiments are possible in which, for example, the diameter D2 and D4, unlike in 1 , for other sizes of pressing elements or plastic pipes, are formed.

2 shows a heating or cooling arrangement 16 in which a capillary tube mat 17 via supply lines 18 with a heating or coolant supply 19 connected is. The capillary tube mat 17 is in each case by means of a connection adapter according to the invention 1 with one of the supply lines 18 fluid-tight and pressure-resistant connected.

The commercial capillary tube mat 17 includes two manifolds 20 and a variety of capillary tubes 21 , each between the headers 20 run and with the headers 20 fluidly connected. During operation of the heating or cooling arrangement 16 a heating or cooling liquid (not shown) flows through the capillary tube mat 17 in a circuit with the heating or coolant supply 19 , The heating or coolant supply 19 Temper the heating or cooling liquid to a desired temperature and pump it via one of the supply lines 18 in one of the manifolds 20 the capillary tube mat 17 , From the one manifold 20 The heating or cooling fluid then flows through the capillary tubes 21 and thereby air-conditioning the interior in which the capillary tube mat is installed. From the capillary tubes 21 the heating or cooling fluid flows into the other manifold 20 and then via the other supply line 18 back to the heating or coolant supply 19 where the cycle starts again.

3 shows the connection of one of the manifolds 20 to one of the supply lines 18 through the connection adapter according to the invention 1 in the embodiment of the 1 in a schematic sectional view.

First, the connection between the manifold 20 the capillary tube mat 17 with the welding connection connection 3 the connection adapter according to the invention 1 described.

The manifold 20 is formed at least at the illustrated axial end of a weldable plastic having an outer diameter D5. For connecting the manifold 20 with the mat side weld connection 3 becomes the manifold 20 heated at the outer diameter D5 in the circumferential direction and at the substantially perpendicular cut end face. At the same time, the socket welding surface is heated 14 and the butt weld area 13 the Schweißverbindungsan circuit 3 , The heating can be done by means of a heating element suitable for plastic welding and generally known. Such a heating element is described for example in the DVS 2208 Part 1 (German Association for Welding). The heating is stopped as soon as the welding surfaces have reached a necessary welding temperature and the plastic has liquefied at these points. Subsequently, the manifold 20 in the pocket 12 the welding connection connection 3 introduced. In this case, the end face of the manifold 20 with the butt welding surface 13 and the front peripheral surface of the manifold 20 with the socket welding surface 14 brought into contact. In this contact or welding area 22 the manifold connects 20 with the welding connection connection 3 cohesively. Ideally, the welding of the manifold 20 with the welding connection connection 3 according to the directive DVS 2208 Part 1 (German Association for Welding). The resulting welded joint is fluid-tight and pressure-resistant in a usual pressure range for capillary tube mats.

Following is the connection of the supply line 18 through a commercially available compression sleeve 23 with the supply-side press-connection terminal 2 described.

In the 3 shown, commercially available compression sleeve 23 is rotationally symmetrical and has two tubular, interconnected at one axial end sleeve portions 24 . 25 on. The compression sleeve 23 is made of a deformable yet solid material such as copper. The two sleeve areas 24 . 25 are integrally formed as a fluid-tight pipe section. In every sleeve area 24 . 25 is at a distance A, for example 10 mm or 4 mm in different embodiments, from the axial end a receptacle 31 formed in the circumferential direction. In every shot 31 is a sealing element 26 , eg an O-ring.

For connecting the compression sleeve 23 with the press connection connection 2 becomes the compression sleeve 23 with the first sleeve area 24 on the pipe socket 28 of the press connection terminal 2 pushed. The socket-side weld connection 3 is designed as an axial stop when pushing. The inner diameter D6 of the compression sleeve 23 is slightly larger than the outer diameter D2 of the press-connection terminal 2 , allowing a slight sliding of the compression sleeve 23 is possible.

The attachment of the compression sleeve 23 gets through the chamfer 5 of the press connection terminal 2 facilitated. Subsequently, a pressing force F is distributed in the circumferential direction, acting radially inwardly on the first sleeve portion 24 applied. By pressing force F is the compression sleeve 23 in the first sleeve area 24 on the contact section 6 of the connection adapter 1 pressed. Due to the compression-resistant design of the pipe socket 28 trained connection element 2 becomes the connection adapter 1 not plastically deformed, but a press connection between the compression sleeve 23 and the connection adapter 1 produced. The sealing element 26 seals the compression sleeve 23 to the pipe socket 28 from. The press connection thus produced is fluid-tight and pressure-resistant in the usual pressure range for capillary tube mats.

In the same way, the second sleeve area 25 the compression sleeve 23 on the end of the supply line 18 pressed. The pressing of the two sleeve areas 24 . 25 can also be done simultaneously. Thus, a fluid-tight and pressure-resistant connection between the manifold 20 the capillary tube mat 17 , the connection adapter 1 , the compression sleeve 23 and the supply line 18 produced. The compound is also resistant to torsion and loadable in the axial direction.

The connection adapter according to the invention 1 is, as described above, formed as a connecting element. In addition, the connection adapter 1 also as an adapter between different diameters D2, D4 of the manifold 20 and the pressing elements 23 . 27 formed.

4 shows a further exemplary embodiment of a connection adapter according to the invention 1 that with the manifold 20 the capillary tube mat 17 and the supply line 18 connected is. In the following, only the differences from in the 1 and 3 illustrated embodiment received.

At the in 4 illustrated embodiment of the connection adapter according to the invention 1 is the press-connection connection 2 with an alternative contact section 106 and pipe socket 128 formed, the plurality of circumferentially extending projections 25 having. The projections 25 project radially outwards and point in longitudinal section, as in 4 , a wavy contour on. Between two projections 25 is in the embodiment in 4 a sealing element 26 , eg an O-ring.

At the in 4 illustrated embodiment of the connection adapter according to the invention 1 becomes the press-connection terminal 2 by means of a commercially available, hollow cylindrical sliding sleeve 27 with the supply line 18 connected. Here, first, the sliding sleeve 27 on the still loose supply line 18 pushed. Subsequently, one end of the supply line 18 on the press connection connection 2 and in particular via the projections 25 pushed. Then the sliding sleeve 27 by means of an axial force F 'in an area around the projections 25 squeezed around. The inner diameter of the sliding sleeve 27 is less than the outer diameter of the supply line 18 in the area that over the protrusions 25 pushed. As a result, when pressing a resultant force F '' generated, which is the supply line 18 from the outside to the press connection connection 2 pressed. This press connection seals the supply line 18 to the supply-side press-connection terminal 2 fluid-tight and pressure-resistant.

5 shows a capillary tube according to the invention 17 , the headers 20 and capillary tubes 21 and two on the headers 20 welded connection adapter according to the invention 1 having. The particular advantage of this invention Kapillarrohrmatte 17 lies in the fact that the connection adapter 1 already during the manufacture of the capillary tube mat 17 be welded. The capillary tube mat delivered in this way 17 Can be connected during installation without the need for plastic welding. Connecting the capillary tube mat 17 with the pressing method described above, for example, by a pipe builder, for example, the supply lines 18 laid, carried out at the installation / installation location. This is the case when installing the capillary tube mat 17 no personnel required, which must be formed in plastic welding and the installation costs of the capillary tube according to the invention reduce. The connection adapter according to the invention 1 provides an interface to common in piping construction installation materials.

Alternatively, it is also possible, a supply line according to the invention 18 at the one not yet with a capillary tube mat 17 connected connection adapter 1 is compressed. The supply line designed in this way 18 can then during installation by the above-described plastic welding process with a manifold 20 a capillary tube mat 17 get connected.

6 shows an alternative connection between a manifold 20 the capillary tube mat 17 with the welding connection connection 3 of the connection adapter 1 , Unlike the in 3 shown connection, has the manifold 20 in 6 a larger diameter D7 and is only frontally with the butt weld 15 of the connection adapter 1 welded. Otherwise is in the 6 represented connection with the in 3 equal.
