Opfindelsen angår en anordning til overføring af fjernvarme til et vandopvarmningsanlæg, omfattende et varmevekslersystem til overføring af varme fra et primært fjernvarmemedium til et sekundært medium, en til vandopvarmningsanlægget hørende cir-5 kulationsledning, en i vandopvarmningsanlægget indskudt cirkulationspumpe og mindst én temperaturføler til afføling af ud-trædningstemperaturen af det varme vand, og af spærrearmaturer i kredsløbene for henholdsvis det primære og det sekundære medium.The invention relates to a device for transferring district heating to a water heating system, comprising a heat exchanger system for transferring heat from a primary district heating medium to a secondary medium, a circulation line belonging to the water heater, a circulation pump inserted in the water heating system and at least one temperature sensor. -treatment temperature of the hot water, and of barrier fittings in the circuits of the primary and secondary medium, respectively.
10 Fra tysk brugsmønster nr. 8 708 283 kendes en fjernvarmeoverføringsindretning i form af en kompakt station, der er monteret på forhånd og derfor er billig i installation. Til varmtvandsforsyning under anvendelse af fjernvarme som primært varmebærende medium krævedes der tidligere en forholdsvis dyr 15 teknik især ved store tilslutningseffekter til varmtvandsforsyning af flerfamiliehuse. Ifølge DIN-normerne 4753 og 4747 kræves der desuden sikkerhedstemperaturbegrænsere ved varmevekslere med en effekt på mere end 50 kW og/eller et vandindhold på mere end 15 liter. Sådanne sikkerhedstemperatur-20 begrænsere er forholdsvis dyre. Ved mindre ydelser og mindre vandindhold er disse temperaturbegrænsere imidlertid ikke nødvendige. Temperaturbegrænsernes andel af de samlede omkostninger til varmtvandsanlæg med stor ydelse er imidlertid så stor, at anvendelsen af transmissionsstationer med stor ydelse er 25 begrænset til varmtvandsområdet.10 From German usage pattern no. 8 708 283 a district heating transfer device is known in the form of a compact station which is pre-installed and is therefore cheap in installation. For hot water supply using district heating as the primary heat-carrying medium, a relatively expensive technique was previously required, especially for large connection effects for hot water supply of multi-family houses. In addition, according to DIN standards 4753 and 4747, safety temperature limits are required for heat exchangers with an output of more than 50 kW and / or a water content of more than 15 liters. Such safety temperature limits are relatively expensive. However, for smaller services and less water content, these temperature limits are not necessary. However, the temperature limiter's share of the total cost of high-performance hot water systems is so great that the use of high-performance transmission stations is limited to the hot water range.
Fra fransk offentliggørelsesskrift nr. 2 531 189 kendes et vandopvarmningsanlæg, hvor det primære medium holdes på et koldere niveau, eksempelvis ved, at det afledes fra en geotermisk kilde, rekuperationsvarme, en varmepumpe eller lig-30 nende. Som varmeoverføringsanordning anvendes to varmevekslere, der ved primærsiden forsynes fra samme varmekilde, hvilke varmevekslere ved sekundærsiden er tilordnet forskellige funktioner og koblingsforbindelser. På sekundærsiden er der et varmtvandslager, der anvendes som buffer og muliggør et ensar-35 tet og lavt energiudtag via varmevekslerne.From French Publication No. 2,531,189, a water heating system is known in which the primary medium is kept at a colder level, for example by being derived from a geothermal source, recovery heat, a heat pump or the like. As a heat transfer device, two heat exchangers are used at the primary side from the same heat source, which heat exchangers at the secondary side are assigned different functions and coupling connections. On the secondary side, there is a hot water storage which is used as a buffer and enables a uniform and low energy output via the heat exchangers.

Formålet med opfindelsen er at anvise, hvorledes man kan reducere installationsomkostningerne af en transmissionsanordning af den indledningsvis nævnte art med en stor ydelse under iagttagelse af sikkerhedsforanstaltningerne ifølge DIN-normer-5 ne.The object of the invention is to provide how to reduce the installation costs of a transmission device of the type mentioned initially with a high performance in compliance with the safety measures in accordance with the DIN standards.
Anordningen ifølge opfindelsen er ejendommelig ved, at varmevekslersystemet består af mindst to varmevekslere af i det væsentlige tilsvarende størrelse og ydelse, og at varmeveksleren ved både primærsiden og sekundærsiden er parallelkoblet og 10 permanent er koblet i parallel til et fælles koldtvandstilløb og til et fælles varmtvandsfremløb, idet der i hver af tilløbsgrenene af koldtvandstilløbet til varmeveksleren er anbragt en reguleringsarmatur til strømningsudligning, og hver af varmevekslerne er dimensioneret til en effekt på mindre end 15 50 kW og et vandindhold på maksimalt 15 1, og der i koldt vandstilløbet foran forgreningerne er anbragt en kombineret friløbs/envejsventil.The device according to the invention is characterized in that the heat exchanger system consists of at least two heat exchangers of substantially similar size and performance, and that the heat exchanger at both the primary and secondary sides is connected in parallel and permanently coupled in parallel to a common cold water supply and to a common hot water supply. in each of the inlet branches of the cold water supply to the heat exchanger a regulating luminaire is provided for flow equalization, and each of the heat exchangers is dimensioned to a power of less than 15 50 kW and a water content of a maximum of 15 1 and a cold water supply is arranged in front of the branches. combined free-flow / one-way valve.
Derved fordeles den ønskede vandopvarmningseffekt over et tilsvarende antal parallelkoblede varmevekslere, således at ydel-20 sen af den enkelte varmeveksler ikke overstiger den af DIN-normerne fastlagte maksimale værdi. Derved kan DIN-normerne overholdes uden brug af sikkerhedstemperaturbegrænsere. Endvidere kan varmtvandsanlæg af forskellige ydelser nu tilvejebringes ved hjælp af varmevekslere af en og samme størrelse.Thereby, the desired water heating power is distributed over a corresponding number of parallel-coupled heat exchangers so that the performance of the individual heat exchanger does not exceed the maximum value determined by the DIN standards. In this way, the DIN standards can be adhered to without the use of safety temperature limiters. Furthermore, hot water systems of various services can now be provided by means of heat exchangers of the same size.
25 En ensartet belastning af varmevekslerne muliggøres ved hjælp af reguleringsarmaturer i tilgangsforgreningerne til de parallelt koblede varmevekslere. Derved opnås ikke kun en betydelig reduktion af installationsomkostningerne gennem bortfaldet af sikkerhedstemperaturbegrænseme ved anlæg til høj ydelse. Der 30 muliggøres også en standardisering af anlægskomponenterne, især varmevekslerne.25 A uniform load on the heat exchangers is made possible by means of control luminaires in the access branches of the parallel heat exchangers. This not only achieves a significant reduction in installation costs through the elimination of the safety temperature limits for high-performance plants. It is also possible to standardize the plant components, especially the heat exchangers.
Endvidere kan der ifølge opfindelsen til sekundærsiden af den enkelte varmeveksler være tilordnet en temperaturføler til afføling af udtrædningstemperaturen af det varme vand, hvilken DK 167509 B1 3 temperaturføler er forbundet med en regulerings arma tur, der er anbragt i den i primærsiden liggende udtrædningsledning af den tilhørende varmeveksler.In addition, according to the invention, a temperature sensor for sensing the exit temperature of the hot water may be assigned to the secondary side of the individual heat exchanger, which temperature sensor is connected to a control arm arranged in the primary side outlet pipe of the associated heat exchanger. heat exchanger.
Desuden kan ifølge opfindelsen cirkulationsledningen være 5 sluttet til indgangen af en parallelkoblet varmeveksler.In addition, according to the invention, the circulation line can be connected to the input of a parallel-connected heat exchanger.
Endelig kan ifølge opfindelsen varmevekslerne være installeret ved siden af hinanden som et batteri og være fastgjort til en mekanisk stabil enhed og være dækket af en kappe.Finally, according to the invention, the heat exchangers can be installed side by side as a battery and be attached to a mechanically stable unit and covered by a sheath.
Opfindelsen skal nærmere forklares i det følgende under hen-10 visning til tegningen, hvor fig. 1 viser en anordning ifølge opfindelsen til overføring af fjernvarme til et vandopvarmningsanlæg, fig. 2 de vigtigste komponenter af anordningen i fig. 1 monteret på en bæreramme og set forfra, og 15 fig. 3 den i fig. 2 viste bæreramme set fra siden.The invention will be explained in more detail below with reference to the drawing, in which: FIG. 1 shows a device according to the invention for transferring district heating to a water heating system; FIG. 2 shows the main components of the device of FIG. 1 is mounted on a support frame and viewed from the front, and FIG. 3 shows the one shown in FIG. 2 is a side view.
Den i fig. 1 viste anordning til overføring af fjernvarme til et vandopvarmningsanlæg omfatter et varmevekslersystem til overføring af varme fra et primært fjernvarmemedium til et sekundært medium. En transmissionsanordning 1 til tilvejebrin-20 gelse af varmt vand er i parallel med en anden transmissions-anordning 2 koblet til frem- og tilbageløbet af en fjernvarmeledning. Armaturer og måleapparater er installeret i frem- og tilbageløbene 3 og 4 af fjernvarmeledningen.The FIG. 1, the device for transferring district heating to a water heating system comprises a heat exchanger system for transferring heat from a primary district heating medium to a secondary medium. A transmission device 1 for providing hot water is connected in parallel with another transmission device 2 to the return and return of a district heating line. Luminaires and measuring devices are installed in the inlet and return lines 3 and 4 of the district heating line.
Transmissionsanordningen 1 har to varmevekslere 10 og 11, hvis 25 primærsider 12 og 13, og hvis af varmt vand gennemstrømmede sekundærsider 14 og 15 er koblet parvist parallelt. Tilgangene 16 og 17 ved primærsiden af varmevekslerne, er via afspærringsarmaturer ved fremløbsledningen 3 og udgangene 18 og 19 ved primærsiden er via regulerings armaturer 20 og 21 over en 4 UK 167509 ΒΊ fælles afspærringsarmatur sluttet til tilbageløbsledningen 4.The transmission device 1 has two heat exchangers 10 and 11, whose primary sides 12 and 13, and whose hot water flowing secondary sides 14 and 15 are connected in pairs in parallel. The inputs 16 and 17 at the primary side of the heat exchangers are via shut-off fittings at the supply line 3 and the outputs 18 and 19 at the primary side are connected via the control fittings 20 and 21 over a 4 UK 167509 ΒΊ common shut-off fittings to the return line 4.
Vandopvarmningsanlægget har desuden et koldtvandstilløb KW med en kombineret friløbs- og envejsventil 23. Bag ventilen 23 deler koldtvandstilløbet KW sig i to forgreninger 24 og 25, der 5 er sluttet til de to tilgange af sekundærsiderne 14 og 15 af varmevekslerne 10 og 11. I koldtvandsforgreningerne 24 og 25 er anbragt reguleringsarmaturer 26 og 27 til indledende udligning af gennemstrømningerne.The water heater also has a cold water supply KW with a combined free-flow and one-way valve 23. Behind valve 23, the cold water supply KW divides into two branches 24 and 25, which are connected to the two inputs of the secondary sides 14 and 15 of the heat exchangers 10 and 11. In the cold water branches 24 and 25 are provided with control fittings 26 and 27 for initial equalization of the flow rates.
Udgangene 28 og 29 af sekundærsiderne 14 og 15 af de parallel-10 koblede varmevekslere 10 og 11 munder ud i et fælles varmt-vandsfremløb 30. Gennem varmtvandsfremløbet 3 0 forsynes nogle tilsluttede tappesteder 31a, 31b ... 3ln med varmt vand. Foran det sidste tappested 31n er der en cirkulationsledning 32, der er ført tilbage til indgangen 33 af sekundærsiden 14 af varme-15 veksleren 10. Ved hjælp af en cirkulationspumpe 34 i cirkulationsledningen 32 føres det varme vand gennem ledningen 32, sekundærsiden 14 og f remløb s ledningen 30, hvorved der ved hvert tappested 31a ... 31n vil være varmt vand til rådighed og næsten uden forsinkelse.The outputs 28 and 29 of the secondary sides 14 and 15 of the parallel-10 heat exchangers 10 and 11 open into a common hot-water flow 30. Through some hot-water flow 30, some connected tapping points 31a, 31b ... 3ln are supplied with hot water. In front of the last tapping point 31n there is a circulation line 32 which is fed back to the inlet 33 of the secondary side 14 of the heat-exchanger 10. By means of a circulation pump 34 in the circulation line 32, hot water is passed through the line 32, the secondary side 14 and feed flow s line 30, whereby at each tapping point 31a ... 31n hot water will be available and almost without delay.
20 En ved udgangen 28 henholdsvis 29 af den enkelte varmeveksler anbragt temperaturføler 36 henholdsvis 37 samarbejder med en reguleringsarmatur 20 henholdsvis 21, således at fjernvarmemediet ved en passende strømningsregulering indstilles på en skaltemperatur ved udgangene 28 og 29.A temperature sensor 36 and 37 respectively disposed at the output 28 and 29 of the individual heat exchanger cooperates with a control fixture 20 and 21, respectively, so that the appropriate heating medium is adjusted to a scale temperature at the outputs 28 and 29 at an appropriate flow control.
25 En startindstilling af reguleringsarmaturen 26 henholdsvis 27 ved opstart af anordningen 1 rækker til opdeling af ydelsesandelen af de parallelt koblede varmevekslere 10 og 11. Det har overraskende vist sig, at anordningen 1 med varmevekslerne 10 og 11 i paralleldrift er fuldstændigt udlignet over hele ef-30 fektområdet, uden at der kræves særlige foranstaltninger til trykudligning ved udgangene 28 og 29 af sekundærsiderne.25 An initial setting of the control luminaire 26 and 27, respectively, at start-up of the device 1 is sufficient to divide the performance proportion of the parallel-coupled heat exchangers 10 and 11. It has surprisingly been found that the device 1 with the heat exchangers 10 and 11 in parallel operation is completely equalized over the entire output. 30 without the need for special pressure equalization measures at the outputs 28 and 29 of the secondary sides.
