Abstract

A quick-installing modurlar system, for laying seamless and non-intersecting pipes in parts of a building whcih are later inaccessible, has soft Cu, soft steel, or plastic pipes with couplings at the ends of the accessible connections. The modular component shown is installed by the window for the heater concerned so that the window, the radiator and component all have one common centre line; the height of the casing for the component at the window (or at any other radiator position) is arranged so that the connections lead directly into teh casing, then turn up through 90 deg. to the couplings and the component. Connection to teh radiator comes out horizontally from its casing and is linked to the angle cock or an angled connector on the radiator by flexible pipes. The casing is pref. lagged with polyurethane foam. insulation. ADVANTAGE - The construction can serve for right or left handed supply. The casing is incorporated in the wall plaster where the radiator will be installed. It is easily encapsulated in foam. The system has no intersections so that it can be a series of linked units.

Description

The invention relates to a flush mounting system for seamless Pipe assembly within the building components with balanced Heat supply for all involved heaters.

A quick assembly system should be trouble-free and reliable can be created. The connecting lines must be from the Roll unwound and without quick soldering or welding connections procedures can be relocated. The connecting parts themselves are outside the floor and wall structure, accessible at all times clog.

The state of the art is the supplier for the planning engineer gungstechnik extremely unsatisfactory because of the quick assembly systems of the prior art are burdened with considerable defects. When planning, you have to decide whether you want a two-pipe or wants to use a one-pipe system.

Both systems have the disadvantage that the connection of the heat body must be done from the floor. The connection has always been led out of the wall. This was a neat thing that could please. That is the reason for this misdevelopment rapid advance of the quick assembly systems.

The connection of the connecting elements of the heating element is only done  after the structural plastering work. Pipe laying from the apartment distributor to the individual heat radiators takes place at Quick assembly system on the raw floor. After this pipe laying with pressure test and test heating the floor structure started, so that these pipes are later completely inaccessible.

The better of the two supply systems available is the two-pipe system because all the heat elements are the same Flow temperature are supplied. The two pipe system of the However, the state of the art is very popular as a quick assembly system it is time-consuming and complex to create because of the apartment distributor to be connected with 2 pipes from each individual heating element is. This fact contributes to the fact that one usually does simpler and cheaper one-pipe system used. This is the case designed that a whole group of Heat bodies can be supplied. The heat bodies are connected from valve to valve with the connecting pipes, the first and the last heating element is connected to the apartment distributor. Although this system can be assembled very easily and quickly, the planning engineer can never really get used to because due to the falling flow temperature, the heating elements in succession have to be made bigger and bigger. This supply system is very unstable. Therefore it is advisable to use only a low tempe the heating circuits. Needed on average you have 2 to 3 heating circuits per apartment for a quick assembly system, which is also very time-consuming.

A great disadvantage of the prior art system is that the heaters either the connections on the left or on the right side. Because of the expensive warehousing there it only holds those with connections on the right side. This forces you to move each supply circuit from left to right to lay on the right. Since this is not always possible, you often have to make a number of crossovers, which is extremely cumbersome.  

A serious deficiency in the systems of the prior art is the complex and cumbersome way of executing the Schnell assembly systems. It takes place in four stages, the time completely be carried out separately.

• 1. Set the apartment distributor and connect to the Boiler through piping (after the shell construction)
• 2. Attach the heat body and connect to the Apartment distributor in the quick mounting system; Trial heating (after the plastering work);
• 3. Remove the heat body (because of the on-site painting and decorating work on the walls);
• 4. Reinstall all heat elements (after completion of the on-site Painting and decorating).

These four stages of execution are annoying mainly because because there is a time gap between them. The construction site must be set up and cleared every time will. After removing the heaters, you just know not where to put it. They are in the way everywhere, because the house is still full of craftsmen. So they are going back and forth pushed, you climb on it and use it as support for craft activities. Even from the floor protruding connections cannot be reused if the heating engineer is called by the architect who Reattach heat sink. That very often gives trouble and Disputes or deductions for the heating engineer.  

The previously described shortcomings of the quick assembly systems of the State of the art clearly shows what we actually do in system planning and practical implementation everything is still missing.

• 1. We need a quick assembly system, which a whole on a heating circuit with a two-pipe system Group of heaters can supply, straightforward is built and a balanced heat supply ensures.
• 2. We need a quick assembly system with one clean wall connection for the radiator supply.
• 3. We very much miss a quick assembly system, which us the intersection-free right or left circle supply with the same system components.
• 4. We want a quick assembly system that it makes it possible for us to complete the completion with pressure test and heating circuit test can without us needing the heaters.
• 5. We would like to have a quick assembly system in module construction, which by the use of more or fewer module units large or small heating systems always provides the same basic pattern, those in their design and especially in assembly are so simple that practically no design or assembly errors can be made more.

Before the time of the quick assembly systems, we could go to a supplier an entire apartment within the floor covering close without having problems with the balance of the Heat distribution. Now we have to, we want it achieve the same effect, lay up to five times more pipe lengths, because each heat body has a separate distributor connection required for the two-pipe quick assembly system.

We don't see this as progress, but as a failure development, because of the many connection lines on the raw floor a significant amount of thermal energy is transferred to the underlying one Apartment or delivered to the basement.

We cannot understand that in the one-pipe system we are the individual Connect the heating element from valve to valve with a tube, and have to go back from the last heat sink to the connection distributor. We need as many pipes for this as with an earlier one Two-pipe system. However, we had many in the latter Branches with solder joints and crossovers in the floor structure in To take purchase.

The required pipe lengths in comparison between a Schnell assembly one-pipe system Figure 1, and a two-pipe supply line Picture 2 with branches and crossings in the floor structure in a conventional way.

We have to investigate why this is so and whether there is none better solution for the heat supply systems there.

Figure 3 shows how a row of 8 heaters after the conventional way, we want one if possible achieve balanced heat supply.

There are branches and for each connection of a heat sink Crossovers that must not be within the floor structure. We want to examine these critical nodes and their function. The following connection connections result:

• a) 1 input connection consisting of: 1 × forward, 1 × return,
• b) 1 supply connection for heating elements, 1 × flow, 1 × return,
• c) 1 outlet connection, 1 × flow, 1 × return.

Accordingly, each of these nodes has three important functions to fulfill.

• 1. The supply for the node itself.
  • a) Input connection
• 2. The supply of the connected heating element.
  • b) supply connection
• 3. The supply of further subsequent nodes.
  • c) outlet connection

We now want to develop a quick assembly system, which contains an element related to the properties of these nodes because we believe that this is the functional one and powerful success of the system arrangement according to Figure 3 must have its cause.

Instead of the nodes "K", their soldering and welding connections with the conventional system in the flooring, as were the over intersections, however, we set a module that each Connection element for the functions a), b) and c) in the quick mounting system is.  

The module block consists of a module element and a module casing. We build the module link so that it is mutual Concatenation of several such links inevitably the active system according to picture 3, which must show the balanced supply of heaters on a supply line.

We place the module housing so that it is both in the area of Laying level under the floor as well as in the connection area of the Protrudes. We would have created the opportunity the vertical from the horizontal laying level of the raw floor To develop the installation level of the wall. The flush-mounted housing of the The module gets the desired horizontal wall outlet for the heat body connection.

So that we can build very flat, the module link receives two Flow chambers that are arranged one above the other without crossing. So that the same module link for both a heat body right-hand and left-hand connection is suitable, let's build it so that side A is the lead on the left, side B (Back) has the forward flow on the right. Since we are from the center line of the Module section measured for both connections have the same dimension, change their forward and reverse when changing the module link Location. The connections are on the front and back intended.

The flush-mounted module housing is installed in front of the on-site Plastering work embedded in the wall, on which the later heat body should be attached. To meet the statutory heat protection regulation and for compact stability it is on the back and foamed in the side walls using construction foam.

After finishing the interior plastering work can be done in no time Work time with side A or side B forward into the module housing be put. All module links are made using copper or Plastic soft pipes connected without crossing so that they form a supply chain.  

We want to build each module component so that it is suitable for the Right or left circle supply is suitable. That is, the entrance of a module element and the output of it must be changed can be. In the legal area supply z. B. is the one outlet connection a) on the left side of the module, the outlet connection c) on the right side of the same.

The reverse is true with the left-hand circuit supply. As well want to work for themselves in a module we also build the supply chain. Also for the supply chain the left or right connection must be made possible, the quick assembly system should really be universally applicable be. Only with this instrument can we really achieve that the versatility of the structural conditions with the System can be managed.

The appropriate structure of the module and the type the module connections with each other and the integration options the module supply chain in a heating circuit connection can be seen from the drawings below.

Explanation of the instructions

The module module Fig. 1 consists of a module member 1 , which can be inserted into the module housing 2 . The module member 1 has a flow chamber 3 with an average flow radius of approximately 75 mm, which connects the connections 5 and 8 . The flow chamber 3 has a connection heater 9 and vent 11 .

Another flow chamber 4 connects the connections 6 and 7 to one another. The average flow radius for the flow chamber 4 is approximately 25 mm.

The outlet connector heater 10 is for the supply of the heat body that is to be connected to the module block.

The housing foam 12 takes place at the rear and on the side. 2 openings 24 are provided in the module housing for the rear pressure foaming.

The module member 1 also has the same connections for the connections 9, 10 and 11 to the rear, so that the supply and return flow for the radiator connection can be changed.

Fig. 6 illustrates how the basic pattern is executed for the combination of modular components. Since the comparative examples for the connection systems of the prior art (Figures 1, 2 and 3) also assume 8 supply units, a supply chain of 8 module units is described here. The module in FIG. 1 applies here as a single module.

If the module modules are connected to each other in this series connection arrangement, then the supply chain has the same properties as the individual module, see FIGS. 2, 3, 4 and 5. There is, however, a considerable difference that we can advance one dimension with this supply chain. We have a large number of supply connections available on one heating circuit connection. In addition, we can change any module or module link in terms of its identity, so that it works differently than the other chain links. However, this is only shown in FIG. 9.

The individual module elements in FIG. 6 can have the following functions here:

Module 1
Starting or ending link in the supply chain. The connection couplings 5 and 6 are provided for the heating circuit supply. Depending on the use, it is determined whether the module links provide the right or left supply for the radiator connection.

Module 2, 3, 4, 5, 6, 7
Links in the supply chain. Each module has a connection piping 5, 6 for the input connection and provides the outlets 7, 8 for connecting a successor module. The reverse can also be done here.

Module 8
Start or end link of the supply chain like module 1. Connections 7, 8 have the same functions as 5, 6 .

Fig. 7 clearly shows how the module supply chain of the basic pattern Fig. 6 acts when the mutual connection of the heating circuit is made.

Module 1 - coupling 5 flow
Module 8 - clutch 7 return
All modules offer flow on the left, return on the right for the heat radiator connection.

All four heating circuit connection options according to FIG. 7 include the balanced heat supply of the module components, which basically means that the pressure available for all the radiator connections is always approximately the same size.

In Fig. 8 it is shown how the basic pattern of the module supply chain Fig. 6 acts when the one-sided connection is made by the heating circuit.

Fig. 8a
Module 1 - coupling 5 flow
Module 1 - clutch 6 return
All modules offer flow on the left, return on the right for the heat radiator connection.

Fig. 8d
Module 8 - coupling 8 flow
Module 8 - clutch 7 return
All modules offer flow on the right, return on the left for the heat radiator connection.

The four heating circuit connection options in FIG. 8 provide the graduated pressure supply for the individual module components, so that module 1 has the highest pressure in FIG. 8a and 8b, and module 8 the lowest available pressure. In Fig. 8c and 8d Module Module 1 has 8 the highest, the lowest pressure.

FIG. 9 shows what changes in the basic pattern of the module supply chain in FIG. 6 when some links of the module components are turned within themselves.

Fig. 9a
Module 1 - coupling 5 flow
Module 8 - clutch 7 return
All modules offer flow on the left, return on the right for the heat radiator connection.

Fig. 9b
as Fig. 9a, but the modules 4, 5, 6 are turned.
The turned modules now offer forward flow on the right and return flow on the left for the radiator connection. All other modules remain the same.

This is the specific transformation of a module within one Module supply chain.

The Fig. 10, 11 show by way of example, the system of the centers of symmetry for window seat body heat and module block on. This will later become the universal connection of the module supply system when the manufacturers have been forced by the demand to give up the right or left connection for the heating elements in favor of the center connection. This universal connection has the following properties in daily practice during planning and execution:

• a) The modular building blocks can go from masonry to masonry be included if only it is specified where the space for the heat body is provided becomes. The placement for the module is then always the center of the installation site.  
• b) It does not have to be made known whether the intended Left or right connector has a heat sink.
• c) Only later, when choosing the heat body, must be determined how long, high or deep the heat body for the required heat output must be.
• d) If the heating output is increased at some point later must, a radiator with greater heat output can be used without any problem, without connecting cables in walls need to be changed if this also has the center connection.
• e) The manufacturing companies can do without the so-called valve compact prefabricated radiators build that the back can also be in front, but simplify their program.

For all heaters with the connections of the state of the art, who are known to have the connection on the left or right, must It should be known how far the supply and return connections are the middle and whether the connection on the left or right of the Middle is. For this reason, the procedure is currently still that the exact size of the heat body is determined. After that first the placement of the module is determined and in the cut-out plans.  

The module block is shown in the cross-sectional drawing Fig. 12, which shows its insertion into the rising masonry of the outer wall of a window parapet.

The module member 1 can later be removed from the module housing 2 at any time. For thermal protection against the cold outside air, the module housing 2 is thermally insulated using 20 mm rigid polyurethane foam. The elastic connection coupling 13 connects the outlet of the module member 9 and 10 with the tap block 14 of the heat body 15 .

The module member 1 is removed from the module housing 2 by removing the upper housing cover 16 with the chromed rosette 17 and the elastic connecting couplings 13 . If the connecting couplings 5, 6, 7, 8 are loosened, the module member can be turned later so that the forward and return can also be interchanged later. The lower housing cover 18 of the module housing 2 has the task of supporting the screed material 21 of the floor structure against the pipe system 20 within the module housing 2 . The upper housing cover 16 mainly serves as a revision opening for the tightness control of the connecting couplings 5, 6, 7, 8 also to enable subsequent access. The housing cover 16, 18-rack module 2 are mounted flush with the surface on the, so that frame 2 and cover 16, 18 are flush with the plaster. This is necessary so that wall plaster 23 and the front of the module can be covered.

The heating engineers then create the module supply chain. Module 2 connects with its input connections 5, 6 to module 1 coupling 7, 8 . Likewise, module 3 connects to module 2, module 4 then to module 3 and so on until the module member 8 has also been supplied. This connection work can be carried out in a very short working time because, as a rule, the distance from the heating element to the heating element is considerably shorter than the path from the heating element to the apartment distributor, as is the case in comparison with the two-pipe system of the prior art.

After the heating circuit chain has been created, as shown by way of example in FIG. 6, it can then still be determined which type of connection of the heating circuit is the cheapest for the entire system circuit. The following are available for this:

Fig. 7 with 4 types of connection, namely Fig. 7a, 7b, 7c, 7d.
Fig. 8 with 4 types of connection, namely Fig. 8a, 8b, 8c, 8d.

The local conditions alone can be decisive for the choice of the heating circuit connection type. The execution stages for a quick assembly system based on modular design are now:

• 1. Set and connect the apartment distributor to the Set boiler, module blocks.
• 2. Creation and connection of the heating circuit chain with pressure and heating circuit test.
• 3. Attach the heaters.
