Description

E32 'H35 takes place when the premises have already started to be used and when you do not have the same access to the individual premises as at an earlier stage of the construction process. Also at other times there is a big problem with accessibility, when a system has to be adjusted or some component replaced or the like.

The energy distribution systems have so far been built with a sub-optimization as a starting point. This sub-optimization means that the systems consist of a number of components, each of which is cost-effective, but where the total cost of the system "on site" or for its maintenance has not received much attention in the development of the structures.

Not only the cost of the installation, but even more the cost and function during the technical life of the system is therefore the basic idea behind the present invention. The invention has created completely new conditions for manufacturing, installing and maintaining an energy distribution system that provides completely new possibilities during the various stages of a building's creation and period of use.

These thoughts and this object are realized according to the invention in that the construction according to the kind initially stated is essentially carried out as stated in the characterizing part of claim 1. Further features and advantages of the invention appear from the following description with reference to the accompanying drawings, which show a preferred, but not limiting, embodiment of the invention. In detail represents in diametrical, partially schematic cross-sections or in perspective views: Fig. 1 an overview view of an exemplary embodiment of an installation unit complete.

Fig. 1 shows an example of how a complete installation unit 1 according to the invention is constructed and fi g.2 shows an example of an installation unit without cabinet 7.

The figures show an embodiment that is only an example of how constituent components are assembled. Thus, within the scope of the invention, the complete installation unit 1 may be provided with additional components and where these may be directly or indirectly mounted on the benefits 3 EEE 135 the advantages 3 alternatively constitute for example a complement to the functional component. As an example, the functional component 5 may comprise electrical actuators instead of the manual ones specified in the fi clocks, as well as that there are mounted sensors for iron reading and tar control of the input valves: In addition, there may be pressure and temperature sensors mounted in the various measuring nipples 12, 13. , 17 and 67 which then allow direct or indirect reading.

In a preferred embodiment of the invention, the various components are mounted in a cabinet to a complete installation unit 1, which leads to the installation - installation work as well as component placement - being completely changed relative to today's installation principles, with the advantages that the invention brings.

The primary pipe system is connected to the unit - inlet 8 and return 9 respectively - and where the connecting pipes at 8 resp. 9 has connection ends 10 which are optionally threaded, provided with fl ends or smooth as fi g.1 indicates.

At the connection 8 - on the inlet side of the unit - is a balancing valve 11, with its measuring nipples 12 resp. 13, mounted as the first component. The balancing valve 11 is advantageously internally threaded at both ends. With a coupling piece 14 the balancing valve 11 is connected to a distributor 3.

The coupling piece has an external thread directed towards the balancing valve 11 and a bayonet connection at the end which connects to the distributor 3. The construction of the bayonet connection is shown in fi gß. The individual distributors 3 are also coupled axially with the same principle and normally 2-4 distributors are connected in series. The last dryer divider normally terminates with a coupling piece 15 which terminates with a plug 18 which is also mounted via a bayonet socket in the coupling piece 15.

At the connection 9 - on the return side of the complete installation unit 1 - a differential pressure valve 16 with its measuring nipple 17 is mounted as the last component. The differential pressure valve 16 is advantageously internally threaded at both ends and is connected to the distributor 3 with a coupling piece 14 in the same way as the balancing valve 11. As the last component on the return side 9 there is a coupling piece 15, which can advantageously be similar to that mounted on the inlet side. As an alternative to the plug 18, this coupling piece can be provided with a coupling 19, where in the individual case, for example, a drain or a deaeration filling dion is mounted.

The advantages 3 and the coupling pieces 14, 15 are mounted in a profile 4, which is described in more detail below.

In order to always be able to carry out a simple installation, or service, of the complete system, the complete installation unit 1 is constructed so that the complete cabinet 7 has a number of sides / parts which together constitute the complete cabinet. The complete cabinet is advantageously made of sheet metal or some suitable plastic material. 10 15 20 25 30 532 'šfBB In order for the installation work to be carried out easily and with good accessibility of all components, the cabinet 7 consists of a back plate 20 and a bottom plate 21 which are advantageously bent in one piece. On this part -20 / 21- the profile 4 is fastened by means of a screw or equivalent. Then the valves, distributors, functional components and coupling pieces that are relevant for the individual system are mounted.

After the pipe work / installation has been completed, the side pieces 22 and 23 and lid 24, respectively, are mounted. after the pipes 25 are connected to the cooperating pipes from, for example, radiators or convectors with which the complete installation unit 1 cooperates. As a final step, the lid 24 is screwed, or otherwise, fixed to the sides 22 and 23 and the sides of the base plate 21, respectively.

The distribution of the total flow out to the various drying units, eg convectors, takes place via shut-off valves 29 mounted in the branch 30 on the distributors 3. The shut-off valve 29 has a pipe connection 31 to which a pipe loop 32 is connected and the return from this pipe loop 33 is connected to the return connection 34 with its pipe coupling 35 to the functional component 5.

The entire installation unit 1 is assembled and function tested, for example test printed at the factory, which provides a high degree of functional safety.

A possible leak in the installation unit l will, due to the fact that it is mounted in a cabinet ll, be easy to indicate and this means that the risk of moisture damage to the building is minimized.

By assembling a number of frictions in an installation unit 1 according to the invention, a number of advantages have been obtained.

Thus, a number of functions have been collected in one place and thus fl removed these from previous locations, where they have been scattered and, for example, mounted in different rooms and often connected to other components in the system. With the present invention, a heating or cooling system can be built up so that the installer installs, for example, heating batteries in the building at a time, to at a later stage connect these to the installation unit 1. The installer can also make his piping from the heating or cooling units up to the installation unit 1 at the same time, to at a later time make the final connection of the various heating or cooling units to the primary energy source or to the pipe system coming from the same.

The possibility has also been created to be able to connect, for example, a part of the building to the complete heating or cooling system without having to connect all other parts of the building at this stage. This means that the installation unit 1 in a first stage comprises a number of distributors 3 and where some or 135 some are provided with plugs in the connections 30. In a second expansion step, additional functional components 5 can be connected, if the need arises. If, from a building technology point of view, there would be no advantage in the installation unit being mounted in a cabinet 7, this embodiment is also an example of how the invention can be carried out - see fig.2.

The installation unit replaces the need for external, eg in each locally mounted valves, to control the fate and thus the room temperature. By using functional components 5 and shut-off valve 29 and other components such as filters and shut-off valves that can be system-specific, all installation and adjustment work of the components that are normally included in normal cooling or heating installations, ie primarily fate control valves, shut-off valves, drain valves and filters, fl removed from the various premises and instead collected in one place, to the installation unit. The installation unit can be mounted in any place, for example in a corridor or in a device room. The individual premises, with its convectors or heating elements, which are connected to the unit, will thus be released from all installation ice work as soon as the supply and return lines are laid between the appliances and the installation unit. Connection of the cables to the installation unit can be done at a later stage. This means that the premises do not have to be accessible at a later stage when, for example, the adjustment work is to be done, or a change takes place in component selection or when servicing components. This is a great advantage ironed out with today's systems where this accessibility is always a requirement.

With an installation unit 1 according to the invention, a concentrated location has been obtained by the functional components and thus a number of advantages as follows: the installation unit 1 means that an accessibility or accessibility to it and thus to the constituent components has been created. ~ all service work can be carried out in one place. connection of the installation unit 1 to the primary pipe system 6 can take place at one time and not necessarily connected to the time when the individual premises are completed or connected to the distribution unit. connection or connection of the individual rooms! the premises can be made successively to the installation unit. 10 15 20 25 30 532 135 - the installation unit 1 can be expanded with additional distributors 3 if, for example, new premises or other room divisions need to be connected at a later stage, without this affecting already connected premises. additions / replacements of functional components can be made at a later stage. - measurement and monitoring of the energy status of the various premises can take place via the installation unit. - with a complete installation unit l reduces the risk of water damage in the building - with an installation unit that is prefabricated, a controlled, functional product is obtained.

The various parts of the installation unit 1 are described in detail in the following Fig gures Fig. 2 shows the installation unit 2 which comprises all the pipe and functional components included in the complete installation unit 1 including the profile 4, except the surrounding cabinet 7 and in a view seen from it the rear part of the installation unit relative to the inlet 8 and the return 9. As a last component, the coupling piece 15 is mounted. In order to obtain an axial mounting position of the coupling piece and thus of other series-connected parts, the coupling piece 15 is provided with a flange 26. The flange has a diameter which is adapted to the profile 4 in such a way that the flange 26 abuts against the end end 27 of the profile. of the coupling piece and of the advantages, given positions are obtained for all pipe protrusions, which start from the Advantages and thus the position of the pipes 32 and 33 in relation to the profile 4 is given. There is no absolute locking of the coupling piece 15 or the advantages 3 in the opposite axial direction, but the lid 24 and its pipe penetrations 28 constitute a guide as well as the final connection of the inlet 8 and the return 9.

Fig. 3 shows the basic structure of the distributor 3.

Normally the advantages are made with 2 pieces of cut-off 30, but the number of cut-offs preferably varies between 1-4 pieces. Function components 5, which can have a number of different functions or a combination of functions, are mounted in these detents. In the description - see fi g.4 - a preferred embodiment of the connection between the functional component and the Benefits has been described, but this embodiment is only an example that falls within the scope of the invention.

The design of the connection ends of the distributors is shown in Fig. 3A.

The figure shows that the distributor has a female part 36 and a trade 37. These two parts are brought together and then the O-ring 38 in the female part will slide up on the cylindrical part 39 of the trade. The female part has an inner diameter 41 with an O-ring groove 40 and a short cylindrical part 42 outside the O-ring groove, with the same diameter as 41. The female part terminates with two lugs 44, located diametrically to each other and each of which preferably extends slightly less than 90 ° around the periphery of the female part. The lugs 10 have an inner diameter which is slightly larger - preferably 1-4 mm - than the inner diameter 41 of the female part and an axial extent which is preferably 2-4 mm.

The handle 37 is designed so that the outer diaphragm 39 with its front phase 45 cooperates with the inner diameter 41 of the female part and with the O-ring 38 at the same time as the handle 37 has two cylindrical portions 46 which after the interconnection of the advantages engage in the female part grooves 43 ledd. The cylindrical portions 46 are located at the same distance from the distributor fl end 47, which forms the end of the trade towards the distributor, as the thickness of the lugs 44 and has a thickness which adapts to and cooperates with the groove 43 and its width. on the cylindrical portions 46 coordinated so that they can be inserted between the two lugs 44 of the female part 36 and the distance between these lugs.

Fig. 3B shows how the benefits 3 are assembled together. In the upper gear, the male and female parts have been pushed together so that the cylindrical part 39 of the trade engages with the female ring O-ring 38 and with the inner diameter 41 of the female part. which means that in this position the lugs 44 of the female part have not come into engagement with the protruding cylindrical portions 46 of the trade.

In the lower part of fi g.3B, the right manifold has been rotated 90 °. In this position, the cooperating connection ends - the male and female parts - have assumed their final position and this means that the two advantages are locked relative to each other in the axial joint. In this position, all detours 30 are parallel and directed in the same direction. In connection with the advantages then being mounted in the profile 4, their mutual position will also be locked in rotation. The locking takes place by the springs 65 which are located on the periphery of the door divider and which are placed with a 90 ° pitch and where one spring passes through the center of the detour 30 and the others thus with 90 ° displacement to this plane engage in the corresponding groove 64 of the profile 4. The length, height and width of the springs have been tested. In practice, the length is approximately the same as the dryer divider excluding its connecting ends, while the width or thickness is about 2-6 mm and the height is preferably about 5-30 mm. The springs advantageously have recesses 77 which provide a material saving and which can of course be varied in shape and number within the scope of the invention.

The distributor can of course be made with only 2 or 3 springs, but 4 capercaillies provide advantages in terms of casting technology, because you get a smoother material distribution of the sleeve to the dry distributor and thus suction is avoided during casting. The assembly of the distributor in the profile is described in detail with reference to Fig. 5. Fig. 4 shows how the various functional components 5 are mounted on the distributors 3.

The branch 30 of the advantages is designed so that a functional component 5 and its connecting end 55 are pushed into the branch 30 and fixed by means of a locking ring 48.

In detail, the detent 30 is formed with an internally responsive surface 49 which cooperates with a guide pin 50 on the connection end 55 and where the guide pin has a diameter which cooperates with the surface 49 and this to give the functional component a controlled, stabilized fixation in the distributor 3. Outside the surface 49 ~ further from the center of the distributor - there is a second inner blackened surface 51 and this surface cooperates with a second cylindrical part 52 on the functional component which has a slightly, preferably 2-5 mm larger diameter, than the guide pin 50. The length of these two turned portions 50 resp. 52 is preferably 10-20 mm. On the cylindrical part 52 there is also an O-ring groove 53 with a mounted O-ring 54.

In order to be able to fix the functional component 5 to the door divider 3, the connecting end 55 has a resilient, open / slotted locking ring 48 mounted in a groove 56 located on the cylindrical part 57, which has a diameter which is a few more mm larger than the adjacent cylindrical surface. 52. The cylindrical part 57 locks the position of the locking ring 48 axially and this locked position is further secured with the flange portion 58 which constitutes the transition from the connecting end 55 of the functional component, to the part which contains the functional part itself.

On the branch of the distributor 30 there is an inner cylindrical surface 59, directly outside the surface 51, with a turned groove 60 having a width and a depth up selected to cooperate with the locking ring 48 and the cylindrical part 57 of the connecting end 55.

When the connecting end 55 is inserted into the branch 30, the two open end portions 61 of the locking ring 48 are compressed and are not released until the connecting end has reached its final position. Then the legs of the locking ring spring out into the groove 60 and lock the connection axially.

The functional component can always be disassembled because then only the two end portions, or the legs on the locking ring 48 need to be pressed together, after which it is easy to pull the connection 55 out of the partition 30.

To guide the functional component - to prevent it from rotating - the branch 30 has two diametrically located projecting portions 62. These portions 62 have an inner diameter which is slightly larger than the outer diameter of the cooperating recess 63 of the connection end 55. When the functional component 5 is pushed into the distributor the protruding portions 62 enter or pass the surface 63 of the connection end 55. The length and protrusion length of the portions 62 are coordinated with corresponding recesses 63 on the end portion 58 of the connection end 55.

Fig. 5 shows how a distributor 3 is mounted in the profile 4.

The profile 4 is advantageously an extruded Al-profile and its main task is to fix the distributor rotationally. In the present invention, the profile has been made to fix two rows of distributors. Means that a row with, for example, three combined distributors is placed in one row, while the corresponding three distributors are mounted in a second row.

The advantages are fixed rotationally in that the profile 4 has circular segments 73 and 74, respectively, with three and 2 grooves 64, respectively, having a width and a depth which are coordinated with the thickness and the radial extent of the springs 65 on the advantages 3. Advantageously, the advantages have 4 springs and where a spring passes through the center of the cut-off 30. These springs can within the degree of the invention have different lengths and shapes but the function of controlling the position of the distributor relative to the profile 4, as well as providing better symmetry in terms of manufacture / casting. of the benefits is the main function.

The distance between the two distributor rows of the profile 4, calculated from the center of the distributors, is chosen so that a simple connection of the various components to be mounted in the individual installation case is obtained. Thus, a distance is selected both in height as well as the other joint, which means that components can be mounted and service carried out at the lowest possible cost. An example of the distance between the two rows is that "a = 80 mm" and "b = 40 mm". The "a-distance" is a measure that indicates the lateral displacement between the two distribution rows center, while the "b-dimension" indicates the height difference between the centers of the distribution rows.

The profile 4 is in principle an L-profile which is also developed to comprise two circular portions and which in a cross-section is designed so that these circle segments constitute portions which touch both L anchors of the L-profile. The L-profile has a base surface 70 and an angular surface 71 which in its upper part has a reinforcement 72 which constitutes a preferably 90 ° angled extension of the surface 71.

The reinforcement 72 goes perpendicularly from the angle surface 71 and also angles again down towards the base surface 70. The reinforcement 72 finally passes to a first concave, circular segment 73 with a circumference of a total of 180 °, which in its rear part, after 90 ° reaches the angle surface 71 and where the angular surface forms the bottom of one of the 3 grooves 64 formed on the circular segment 73. At the lower edge of the circular segment 73 the profile extends a further distance, a surface 75, away from the angular surface 71 and parallel to the base surface 70. Depending on the diameter of the distributor 3, which is advantageously smaller than that of the dimension "b" of the profile, the profile also comprises an inclined plane 76, which connects the surface 75 to a second cylindrical, concave circle segment 74 which in its lower part ends with a groove 64 whose bottom part is part of the total base surface 70. The circle segment 73 has 3 grooves 64 with a 90 ° pitch and where the central groove extends perpendicularly from the angle surface 71.

The second circular segment 74 comprises only 2 grooves 64 and where one extends perpendicularly from the base surface 70 and the second groove is located 90 ° offset and in the direction of the angular surface 71. The radius of the two circle segments 73 and 74 is chosen to cooperate with the outer diaphragms of the distributors 3.

The profile 4 can naturally have a somewhat armor-like design within the scope of the invention.

The main function is to fix the advantages 3 in desired positions and also indirectly relative to the cabinet 7, since the profile is advantageously screwed to the cabinet 7 in a purposeful manner.

The profile also provides a high degree of freedom in terms of mounting the benefits and thus of other components. Because the profile is completely open in its end portions, the advantages can easily be replaced because they do not need to be screwed or otherwise locked in the axial joint. Iii-BE 'EEE 10 Fig. 6 shows a schematic embodiment of a functional component 5.

This component can be, for example, a shut-off, a vent or a control valve.

Fig. 6 shows a simple throttle valve 66 with a measuring nipple 67. These details are not described in more detail, as they only constitute examples of components that can be used in the complete installation unit 1.

Fig. 7 shows how a functional component 5 is connected to the dryer divider 3 and to the consumption side.

From the installation unit 1 a number of parallel connected loops or pipes 32 go out to radiators or convectors or equivalent energy devices and the return from these loops 33 is connected to the return connection 34 of the functional grain cone 5 with e.g. a pipe connection 35. And to these two detours two functional components are thus connected.

Functional components are in this case a standard variant of a temperature-controlled throttle valve 66 with mounted direct-acting actuators 69. Also in this case there is a measuring nipple 67 on the functional component.
