Opfindelsen angår en indretning til transmission af fjernvarme til et opvarmnings- og/eller vandopvarmningsanlæg drevet af et medium i kredsløbet af et sekundært system, på et ved hjælp af en cirkulationspumpe i hvert fald til dels i kredsløbet ført 5 sekundært system, mindst én reguleringsarmatur til mængderegulering og med en varmeveksler, idet der i indretningen er tilvejebragt mindst to vertikale og parallelt og med indbyrdes afstand forløbende ledninger, der er forbundet indbyrdes over mindst én tværstræber og tjener som bærekonstruktion for ind-10 retningens komponenter.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a device for transmitting district heating to a heating and / or water heating system driven by a medium in the circuit of a secondary system, on a secondary system supplied by means of a circulation pump, at least partly in the circuit, at least one volume control and with a heat exchanger, providing at least two vertical and parallel and spaced wires connected to each other over at least one transverse strut and serving as a carrier structure for the components of the device.

Indretninger af denne art kan anvendes som transmissionsstation og huscentral for rumopvarmning og/eller vandopvarmning med fjernvarme som primær energibærer. Rørledningerne er da fortrinsvis via flanger forbundet indbyrdes og med rørar-15 maturer, stille- og måleled i området af transmissionsstationen og huscentralen. Montagen af rørledningerne og komponenterne af transmissionsstationen må ofte foretages individuelt og under hensyntagen til pladsforholdene, hvilket giver betydelige montageomkostninger i forbindelse med forholdsvis høje 20 anlægsomkostninger. Høje tilslutningsomkostninger har ofte været årsag til, at fordelene ved fjernvarmeforsyning ikke kunne udnyttes fuldt ud.Devices of this kind can be used as a transmission station and housing center for space heating and / or water heating with district heating as the primary energy carrier. The pipelines are then preferably interconnected via flanges and with pipe fittings, control and measurement links in the area of the transmission station and the house central. The installation of the pipelines and components of the transmission station must often be done individually and taking into account the space conditions, which results in considerable installation costs in connection with relatively high construction costs. High connection costs have often been the reason why the benefits of district heating could not be fully utilized.

Fra EP-patentskrift nr. 92.032 kendes et apparat af denne art, hvor de to vertikale og parallelle og indbyrdes adskilte led-25 ninger og mindst én gennemstrømmet tværst iver er forbundet indbyrdes. Bærekonstruktionen er fremstillet ud i ét af presset eller støbt jern og består af et raster af firkantede rør. Rørledningerne for tilslutning til det primære varmesystem og til opvarmnings- og/eller vandopvarmningsanlægget har ingen 30 bærende funktion.EP Patent No. 92,032 discloses an apparatus of this kind in which the two vertical and parallel and mutually separate wires and at least one flowing transverse zipper are interconnected. The support structure is made of one of pressed or cast iron and consists of a square of square tubes. The piping for connection to the primary heating system and to the heating and / or water heating system has no supporting function.

En adskillelse af det primære fjernvarmesystem fra et af et andet medium drevet sekundærsystem kan kun ske ved hjælp af indbyrdes adskilte bærekonstruktioner.A separation of the primary district heating system from a secondary medium driven by a secondary system can only be effected by means of spaced-apart carrier structures.

2 DK 168054 B12 DK 168054 B1

Formålet med opfindelsen er at tilvejebringe en indretning af den indledningsvis nævnte art med en bærekonstruktion, der er egnet til fritstående udførelse og til vægmontage, hvilken indretning mod mediesiden skal muliggøre en adskillelse af op-5 varmnings- og/eller vandopvarmningsanlægget fra det primære fj ernvarmesystem.The object of the invention is to provide a device of the type mentioned above with a support structure suitable for freestanding design and for wall mounting, which device for the media side should enable separation of the heating and / or water heating system from the primary heating system. .

Dette formål er ifølge opfindelsen opnået ved, at de to systemer er indbyrdes adskilt af en varmeudveksler og danner separate kredsløb, og at de som cylindriske rørledninger udformede 10 kredsløbskanaler er ført oppefra vertikalt og indbyrdes parallelt til indretningen, og i hvert fald to af de med fjernvarmekredsløbet og/eller sekundærkredsløbet forbundne rørledningsafsnit sammen med en ikke gennemstrømmet horisontal tværstræber danner bærekonstruktionen, og at indretningen til 15 understøtning af bærekonstruktionen på fladen ved opstillingsstedet ved den mod bunden vendende ende er udstyret med foddele, der danner en understøtningsflade.This object is achieved according to the invention in that the two systems are mutually separated by a heat exchanger and form separate circuits, and the 10 circuit channels formed as cylindrical pipelines are led vertically and parallel to one another, and at least two of the the district heating circuit and / or the secondary circuit connecting pipe sections together with a non-flowing horizontal transverse strip forming the support structure, and the device for supporting the support structure on the surface at the mounting point at the bottom end is provided with a foot portion forming a support portion.

Derved muliggøres en driftsklar montage med stikfærdige ledningsføringer, da der under indbygningen af indretningen kun 20 skal foretages en tilslutning af enderne til de oppe fra vertikalt og parallelt til indretningen førte rørledninger. Da i hvert fald to af de med fjernvarmekredsløbet og/eller sekundærkredsløbet forbundne rørlednings af snit er en del af indretningen, reduceres pladsforbruget.This allows for ready-to-use installation with plug-in wiring, since during the installation of the device only 20 connections must be made to the ends of the pipelines led up from the vertical and parallel to the device. Since at least two of the cut pipelines connected to the district heating circuit and / or the secondary circuit are part of the device, space consumption is reduced.

25 Indretningen kan opstilles ved bunden af et indsætningssted, og kan opstilles ved en væg eller være fritstående på en vandret flade.The device may be positioned at the bottom of an insertion site and may be mounted at a wall or be free-standing on a horizontal surface.

En særlig stabil udførelse består i, at de langsgående stivere er dannet af de fjernest fra hinanden placerede vertikale rør-30 ledninger, fortrinsvis gennem et rørafsnit af fjernvarmef remløbet og et rørafsnit af tilbageløbet af sekundærkredsen. Det nedre afsnit af en af de rørledninger, der danner en langsgående stiver, er udformet som slamfælde og er forsynet med en 3 DK 168054 B1 slamventil. Derved kan en åben ende af et til rørledningen hørende faldrør neddyppes i et udvidet aflejringskammer af slamfælden, idet aflejringskammeret har et udløb over mundingsstedet af faldrøret.A particularly stable embodiment consists in that the longitudinal struts are formed by the most distant vertical pipe lines, preferably through a pipe section of the district heating flow and a pipe section of the reflux of the secondary circuit. The lower section of one of the pipelines forming a longitudinal strut is designed as a sludge trap and is provided with a sludge valve. Thereby, an open end of a pipeline belonging to the pipeline can be immersed in an expanded deposition chamber of the sludge trap, the deposition chamber having an outlet over the mouth of the trap pipe.

5 Til stabilisering af de til bærekonstruktionen hørende og fortrinsvis af stål bestående rørledninger har den enkelte tværstiver fortrinsvis et kvadratisk profil. Tværstiveren forløber vinkelret på de langsgående stivere og er svejst til disse. Ved de flader, hvortil der skal svejses, kan profilet tilpas-10 ses til de forskellige rørledningsafsnit.5 For the stabilization of the supporting conduits and preferably of steel pipes, the individual transverse struts preferably have a square profile. The cross brace extends perpendicular to the longitudinal braces and is welded to them. At the surfaces to be welded, the profile can be adapted to the different pipe sections.

I en foretrukken udførelsesform har den enkelte foddel mindst én til planet af de langsgående stivere vinkelret forløbende glidestok, der kan indstilles i højden, eksempelvis i form af skruefødder til udligning af uensartetheder af undergrunden 15 eller svage hældninger af de langsgående stivere.In a preferred embodiment, the individual foot portion has at least one perpendicular slider extending perpendicularly to the plane, which can be adjusted in height, for example in the form of screw feet to offset disparities of the subsurface 15 or slight slopes of the longitudinal struts.

Endvidere kan ifølge opfindelsen rørledningerne og armaturerne af transmissionindretningen være forbundet indbyrdes via skrue- og/eller svejseforbindelser. Skrue- og svejseforbindelser muliggør en afkortning af rørføringen og derigennem en 20 mere kompakt udførelse af den samlede indretning. Dertil kommer at rørforbindelser har mindre udstrålingsflader end flangeforbindelser.Furthermore, according to the invention, the pipelines and luminaires of the transmission device may be interconnected via screw and / or welding connections. Screw and weld connections allow shortening of the piping and thereby a more compact design of the overall device. In addition, pipe joints have smaller radiating surfaces than flange joints.

Pladevarmeveksleren med dertil sluttede rørledningsafsnit og komponenter af fjernvarme frem- og returløbet er fortrinsvis 25 dækket af en hætteformet beklædning i hvert fald fortil. Denne beklædning er løsbart fastgjort til bærekonstruktionen. Gennem den af fabrikantens fastlagte og optimerede anbringelse af -komponenterne og rørføringen kan man ved en beklædning af stationen minimere varmeudstrålingen til omgivelserne. Samti-30 digt bibeholdes tilgængeligheden til komponenterne af indretningen, eftersom den hætteformede beklædning vil kunne afta ges.The plate heat exchanger with associated pipeline sections and components of the district heating feed back and forth is preferably covered by a hood-shaped cover at least in the front. This garment is detachably attached to the carrier structure. Through the manufacturer's determined and optimized placement of the components and the piping, one can minimize the heat radiation to the surroundings by coating the station. At the same time, accessibility to the components of the device is maintained as the cap-shaped cladding can be removed.

En central reguleringsenhed, kan ifølge opfindelsen være monteret i den hætteformede beklædning foran rørledningsafsnittet af fjernvarmef remløbet og -returløbet og være synlig fra forsiden. Beklædningen kan bestå af en eller flere blikdele eller 5 udgøres af formstof.A central control unit, according to the invention, may be mounted in the hood-shaped cladding in front of the pipeline section of the district heating flow and return flow and be visible from the front. The garment may consist of one or more tinplate parts or 5 constitute plastic material.

Til vandopvarmning kan der være tilsluttet en parallel forgrening til fjernvarme frem- og tilbageløbet. Den dertil hørende varmeveksler kan være anbragt ved et yderligere bæremodul i form af en bæreramme eller ved en af systemets rørledninger 10 dannet bærekonstruktion. Derved sammenfattes vandopvarmningsanlægget ligesom opvarmningsanlægget ved transmissionsstationen til en præfabrikeret enhed, der er klar til indbygning. Et vandopvarmningsanlæg vil kunne eftermonteres uden problemer, eftersom det kan tilsluttes som et yderligere modul og deref-15 ter justeres.For water heating, a parallel branch may be connected to the district heating back and forth. The associated heat exchanger may be provided by a further support module in the form of a support frame or by a support structure formed by the system's pipelines 10. In this way, the water heater, like the heater at the transmission station, is summarized into a prefabricated unit ready for installation. A water heater can be retrofitted without problems, since it can be connected as an additional module and then adjusted.

2 0 Ved tilslutningsstederne af frem- og returløbene 4, 5 er der indskudt en manuelt betjenelig afspærringsarmatur. Til koldt-vandsfremløbet og varmtvandskredsløbet er tilsluttet en trykekspansionsbeholder 12. På hovedkomponenterne af transmissionsindretninger inklusive en varmeveksler er beklædningsdele 25 7 anbragt til siden for en lomme 13 for en betjeningsvejled ning.2 0 A manually operable shut-off luminaire is inserted at the connection points of the forward and return lines 4, 5. To the cold-water flow and the hot-water circuit is connected a pressure expansion vessel 12. On the main components of transmission devices including a heat exchanger, casing parts 25 7 are arranged to the side of a pocket 13 for operating instructions.

Den i fig. 1 og 2 viste indretning er kompakt og er alligevel efter aftagning af beklædningsdelene 7 tilgængelig for reparation og vedligeholdelse. Beklædningsdelene 7 virker som kon-30 vektorer uden selv at blive overophedet. Derved muliggøres en indbygning af indretningen; ikke kun i særlige rum, men også i 6 DK 168054 B1 arbejds- og hobbyrum.The FIG. 1 and 2 are compact and yet accessible after repair of the clothing parts 7 for repair and maintenance. The cover members 7 act as convectors without overheating themselves. This makes it possible to incorporate the device; not only in special rooms, but also in 6 DK 168054 B1 work and hobby space.

Fig. 3 viser et diagram over transmissionsindretningen med dertil hørende komponenter. Elementerne af selve indretningen 1 er vist inden for et stiplet afgrænset midterområde og kan 5 være forudmonteret. Endvidere ses beklædningen og den tilslutningsfærdige ledningsføring ved rammen 10. Fjernvarmef remløbet 2 er tilordnet en manuelt betjent afspærringventil, et manometer, et termometer, en urenhedsfanger og en tempera tur føl er. Via en pladevarmeveksler 15 overføres varme fra fjernvarme- 10 kredsløbet 2, 3 til et i varmekredsløbet 4, 5 cirkulerende medium. Fjernvarmemediet gennemstrømmer varmeveksleren 15 i modstrøm til varmemediet og tilbageføres via returløbet 3 til fjernvarmenettet. Returløbet 3 indeholder en tomgangsventil, en volu-menreguleringsenhed 16, en volumenmåler 17, en tempe-15 raturføler, et termometer, et manometer og en af spærrings ventil .FIG. 3 shows a diagram of the transmission device with associated components. The elements of the device 1 itself are shown within a dotted defined center region and 5 may be pre-assembled. Furthermore, the lining and the finished wiring are seen at frame 10. The district heating circuit 2 is provided with a manually operated shut-off valve, a pressure gauge, a thermometer, an impurity trap and a temperature sensor. Via a plate heat exchanger 15, heat is transferred from the district heating circuit 2, 3 to a medium circulating in the heating circuit 4, 5. The district heating medium flows through the heat exchanger 15 countercurrent to the heating medium and is returned via the return flow 3 to the district heating network. The return flow 3 contains an idle valve, a volume control unit 16, a volume meter 17, a temperature sensor, a thermometer, a pressure gauge and a shut-off valve.

På fremløbssiden indeholder opvarmningskredsløbet en temperaturføler 19, en sikkerheds temper a tur overvågnings enhed 20, en sikkerhedsventil, en cirkulationspumpe 21, et termometer og en 20 afspærringsarmatur. Opvarmningskredsløbet sluttes via et varmeanlæg 22 og varmereturløbet 5. Sidstnævnte er tilordnet en yderligere af spærrings armatur, et termometer, en urenhedsfanger, en tilslutning til trykekspansionsbeholderen 12 og en tomgangsventil. Tilslutningen til varmeveksleren 15 er således 25 udformet, at fjernvarmemediet gennemstrømmer primærsiden 25 i medstrøm til varmemediet på sekundærsiden 26.On the supply side, the heating circuit contains a temperature sensor 19, a safety tempera ture monitoring unit 20, a safety valve, a circulation pump 21, a thermometer and a 20 shut-off fixture. The heating circuit is connected via a heating system 22 and the heat return circuit 5. The latter is assigned a further of the shut-off luminaire, a thermometer, an impurity trap, a connection to the pressure expansion vessel 12 and an idle valve. Thus, the connection to the heat exchanger 15 is designed so that the district heating medium flows through the primary side 25 in co-current to the heating medium on the secondary side 26.

I diagrammet i fig. 3 er vist et motordrev 27 for et stilleled 28 af volumenreguleringsenheden 16. Motordrevet 27 reguleres i afhængighed af vejret og temperaturen via en elektrisk regule-30 ringsenhed 9. Regulerings enheden 9 kan endvidere indkoble cirkulationspumpen 21 i varmekredsløbet. Koaksialt med motordrevet 27 og på den anden side af stilleleddet 28 er der en volumenstrømsbegrænser 29, der også kan påvirke stilleleddet.In the diagram of FIG. 3, a motor drive 27 is shown for a slider 28 of the volume control unit 16. The motor drive 27 is controlled, depending on the weather and the temperature, via an electric control unit 9. The control unit 9 can also switch on the circulation pump 21 in the heating circuit. Coaxially with the motor 27 and on the other side of the scaffold 28 there is a volume flow limiter 29 which can also affect the scaffold.

7 DK 168054 B1 I diagrammet i fig. 3 er desuden vist en tilslutning 30 til et vandopvarmningsanlæg. Dette anlæg kan monteres i en separat ramme ved siden af rammen 10 og dækkes på passende måde.7 DK 168054 B1 In the diagram of FIG. 3 is also shown a connection 30 to a water heater. This system can be mounted in a separate frame next to the frame 10 and covered appropriately.

Fig. 4 og 5 viser de til transmi s s ions indretningen 1 hørende 5 komponenter af fjernvarme- og opvarmningskredsløbet. Fig. 5 viser komponenterne af fjernvarmekredsløbet 3 i retning af pilene A-A i fig. 4.FIG. 4 and 5 show the 5 components of the district heating and heating circuit belonging to the transmission device 1. FIG. 5 shows the components of the district heating circuit 3 in the direction of arrows A-A in FIG. 4th

De vertikale rørafsnit af fjernvarme- og opvarmnings frem- og -returløbene 2, 5 er ved hjælp af rørbøjler 40 med lyddæmpende 10 indlæg løsbart fastgjort til tværdragere af bærerammen 10.The vertical pipe sections of the district heating and heating circuits 2, 5 are detachably fastened to transverse supports of the carrier frame 10 by means of pipe hangers 40 with muffler 10 inserts.

Afspærringsarmaturen, varmeveksleren 15, ledningsarmaturen og stilleleddet 28 er skruet sammen indbyrdes og med rørene. Der er ikke flangeforbindelser i denne udførelsesform. Derved forkortes ledningsstrækningerne, og pladsforbruget af den sam-15 lede indretning reduceres, og varmeudstrålingsfladen af de komponenter, der kommer i berøring med varmemediet, reduceres. Fjernvarmekredsløbet fører i fig. 4 fra fremløbet 2 via en forreste tilslutningsstuds 32 gennem varmeveksleren 15, gennemløber denne vertikalt og afgives for neden via en rørstuds 20 33 til returløbet 3. Det forholdsvis kolde vand fra returløbet 5 indføres forneden i en ikke vist rørstuds af varmeveksleren 15, strømmer medstrøms i forhold til varmemediet gennem varmeveksleren 15 i opadgående retning og afgives via en rørformet studs 34 i varmefremløbet 4. Tem-peraturføleren 19, tempera-25 turovervågningsenheden 20 og cirkulationspumpen 21 er i fig. 4 vist i forbindelse med fremløbet 4.The shut-off fixture, the heat exchanger 15, the wiring fixture and the switching link 28 are screwed together and with the pipes. There are no flange connections in this embodiment. Thereby, the conduits are shortened and the space consumption of the entire device is reduced and the heat radiating surface of the components coming into contact with the heating medium is reduced. The district heating circuit in FIG. 4 from the inlet 2 via a front connection nozzle 32 through the heat exchanger 15, it passes vertically and is delivered below through a pipe nozzle 20 33 to the return nozzle 3. The relatively cold water from the return nozzle 5 is introduced below into a pipe nozzle of the heat exchanger 15, flowing downstream relative to the heating medium through the heat exchanger 15 in an upward direction and is delivered via a tubular stud 34 in the heat flow 4. The temperature sensor 19, the temperature monitoring unit 20 and the circulation pump 21 are shown in FIG. 4 shown in connection with the flow 4.

Returløbet 3 er som følge af skrueforbindelsen og den særlige udformning og placering af regulerings enheden 16 udformet på en pladsbesparende måde. I regulerings enheden 16 er volumen-30 strømsbegrænseren 29 og motordrevet 27 anbragt koaksialt og kan fra hver sin side over en adapter 31 påvirke det samme ventillegeme af stilleleddet 28.Due to the screw connection and the special design and positioning of the regulating unit 16, the return passage 3 is designed in a space-saving manner. In the control unit 16, the volume flow limiter 29 and the motor drive 27 are coaxially disposed and can, from each side, over an adapter 31 actuate the same valve body of the actuator 28.

Derved undgås flere ved siden af hinanden anbragte stilleled, DK 168054 B1 8 der skal betjenes individuelt fra motordrevet 27 og volumen-strømsbegrænseren 29. Specielt undgås et separat ventillegeme og et yderligere ventilhus i returløbet 3.This avoids several adjacent linkages, DK 168054 B1 8 to be operated individually from the motor driven 27 and the volume flow limiter 29. In particular, a separate valve body and a further valve housing in the return flow 3 are avoided.

Armaturen og ledningerne af returløbet er ved hjælp af rørbøj -5 ler 41 understøttet af en til rammen fastgjort konsol 42. Denne konsol 42 kan desuden understøtte varmeveksleren 15.The luminaire and the wiring of the return flow are supported by a tube bracket 41 supported by a bracket 42 attached to the frame. This bracket 42 can further support the heat exchanger 15.

Tilslutningen til varmtvandsanlægget 30 er vist stiplet i fig.The connection to the hot water system 30 is shown dotted in FIG.

Fig. 6-9 viser en fjernvarmetransmissionsindretning 100 i en 10 anden udførelse. Transmissionsindretningen har i denne udførelsesform i hovedsagen de samme komponenter som i den første udførelsesform. Diagrammet i fig. 3 gælder derfor i princippet også for den i fig. 6-9 viste indretning. Komponenterne i fig. 6-9 er forsynet med de samme henvisnings tal som i fig.FIG. 6-9 show a district heating transmission device 100 in a second embodiment. In this embodiment, the transmission device has substantially the same components as in the first embodiment. The diagram of FIG. 3, therefore, applies in principle also to that of FIG. 6-9. The components of FIG. 6-9 are provided with the same reference numerals as in FIG.

15 3.15 3.

Transmissionsindretningen 100 adskiller sig fra transmissions-indretningen 1 ved, at den har en anden bærekonstruktion. I stedet for en flad bæreramme anvendes en bærekonstruktion 101 bestående af mindst to vertikale rørledninger 2 og 5 med en 20 svejst tværstræber 102 af kasseformet (kvadratisk) tværsnit.The transmission device 100 differs from the transmission device 1 in that it has a different carrier structure. Instead of a flat support frame, a support structure 101 consisting of at least two vertical pipelines 2 and 5 with a 20 welded cross bar 102 of square (square) cross section is used.

De vertikale rørledninger 2 og 5 har ud over deres driftsmæssige funktion som fjernvarmef remløb og -returløb også en bærefunktion af de vertikale sider af bærerammen 10 - se fig. 4. Ved transmissionsstationer først og fremmest store transmis-25 sionsstationer anvendes stålrørledninger, hvis mekaniske stabilitet er tilstrækkelig til at de kan tjene som understøtningsorganer. Bærekonstruktionen 1 er snoningsstiv takket være den mekaniske fastgørelse af fjernvarmereturløbs- og opvarmningsf remløbsledningerne 3 og 4. Rørledningerne 3 og 4 er 30 svejst til de af flere delafsnit bestående tværstræbere 102.The vertical pipelines 2 and 5 have, in addition to their operational function as district heating flow and return flow, also a supporting function of the vertical sides of the support frame 10 - see fig. 4. At transmission stations, first and foremost large transmission stations, steel pipelines whose mechanical stability is sufficient to serve as supporting means are used. The support structure 1 is twisted rigid thanks to the mechanical attachment of the district heating return and heating feed lines 3 and 4. The pipelines 3 and 4 are welded to the cross sections 102 of several sections.

Rørledningerne 2 og 5 er forlænget i nedadgående retning gennem niveauet af varmeveksler-tilslutningsstudsene 32.
