En sådan fremgangsmåde og et sådant system kan anvendes i forbindelse med opvarmnings- og/eller køleanlæg med i det mindste en varme- og/eller kuldegenerator, adskillige forbrugere, rørledninger til forbindelse af varme- og/eller kuldegeneratoren med forbrugerne og i det mindste en cirkulationspumpe samt med rumtemperaturfølere anbragt i de rum, som skal opvarmes eller afkøles, og med i fremløbs- eller returløbsledningen til henholdsvis fra forbrugerne indbyggede reguleringsarmaturer.Such a method and system can be used in connection with heating and / or cooling systems with at least one heat and / or cold generator, several consumers, pipelines for connecting the heat and / or cold generator with the consumers and at least one circulation pump as well as with room temperature sensors located in the rooms to be heated or cooled, and with in the supply or return line for control built-in luminaires respectively.
Til sikring af en behovstyret forsyning af alle forbrugere i et opvarmnings- eller køleanlæg og til minimering af energiforbruget er den hydrauliske balancering nødvendig. Denne kan ske på mange forskellige måder.To ensure a demand-controlled supply of all consumers in a heating or cooling system and to minimize energy consumption, hydraulic balancing is necessary. This can happen in many different ways.
Kendt er den statiske hydrauliske balancering med anvendelse af forudindstillelige ventiler, som på basis af deres indstillelige Kv-værdi muliggør en gennemstrømningsbegrænsning. Med sådanne ventiler bliver fuldlasttilfældet, dvs. tilfældet med maksimalt samtidigt varme- hhv. kuldebehov for alle forbrugere, indreguleret, med henblik på at undgå en underforsyning. I dellasttilfældet er en overforsyning af individuelle forbrugere givet. Det er ligeledes kendt i større bygninger supplerende at anvende strengreguleringsventiler i forsyningsstrengene, med henblik på at fordele de svarende til bygningsstørrelsen forøgede volumenstrømme behovstyret, og med henblik på at undgå for høje differenstryk over ventilerne og dermed strømningsstøj.Known is the static hydraulic balancing with the use of preset valves which, on the basis of their adjustable Kv value, allow a flow limitation. With such valves the full load is applied, ie. in the case of maximum simultaneous heat or heat. cold needs for all consumers, regulated, in order to avoid an under-supply. In the partial load case, an over-supply of individual consumers is given. It is also known in larger buildings to additionally use string control valves in the supply strings, in order to distribute the volume flow requirements demand controlled, corresponding to the building size, and to avoid excessive differential pressures over the valves and thus flow noise.
Med henblik på tilvejebringelse af forudindstillingsværdierne for ventilerne for den statiske hydrauliske balancering er det kendt at gennemføre en beregning af varmebelastningen og rørnettet, med henblik på, på den ene side ud fra den nødvendige varmemængde for et rum, på den anden side ud fra den givne temperaturdifference imellem fremløb og returløb, at kunne beregne den nødvendige volumenstrøm ved hver forbruger. Ud fra den beregnede volumenstrøm, de opsummerede strømningsmodstande for yderligere gennemstrømmede anlægsdele og det til rådighed stående differenstryk fra pumpen, kan indstillingen af gennemstrømningstværsnittet for ventilerne for den statiske hydrauliske balancering tilvejebringes.In order to provide the preset values for the static hydraulic balancing valves, it is known to perform a calculation of the heat load and the pipe network, in order, on the one hand, from the required amount of heat for a room, on the other hand from the given temperature difference between flow and return flow, being able to calculate the required volume flow at each consumer. From the calculated volume flow, the summed flow resistances for further flowed plant parts and the available differential pressure from the pump, the adjustment of the flow cross section of the valves for the static hydraulic balancing can be provided.
Ligeledes er det kendt i forbindelse med ikke nøjagtigt kendte rørnet at gennemføre en indregulering ved hjælp af måleapparatur, med henblik på at indstille volumenstrømmene ved ventilerne.Also, it is known to carry out an adjustment by means of measuring apparatus in order to adjust the volume flows at the valves in connection with not exactly known piping.
En ulempe er i begge tilfælde det forøgede besvær ved beregningen og indreguleringen, som skal gennemføres manuelt.A disadvantage in both cases is the increased difficulty in calculating and balancing which must be carried out manually.
Desuden er den dynamiske hydrauliske balancering kendt, ved hvilken det fluidførende anlæg ikke kun balanceres hydraulisk for fuldlasttilfældet men også for dellasttilfældet. Hertil bliver enten differenstrykregulatorer anbragt i frem- eller returløbsstrengene i opvarmnings- og/eller køleanlægget, eller gennemstrømningsregulatorer anvendt direkte ved forbrugerne.Furthermore, the dynamic hydraulic balancing is known, in which the fluid carrying system is not only hydraulically balanced for the full load case but also for the partial load case. To this end, either differential pressure regulators are placed in the feed or return lines of the heating and / or cooling system, or flow regulators are used directly by consumers.
For den hydrauliske balancering med sådanne ventiler er ligeledes en varme-belastnings- og en forenklet rørnetberegning nødvendig, med henblik på korrekt at indstille volumenstrømmene til forbrugerne.For the hydraulic balancing with such valves, a heat load and a simplified pipeline calculation are also needed, in order to properly adjust the volume flows to the consumers.
Desuden er det fra EP 1 936 288 B1 kendt, at detektere en foreliggende hydraulisk balancering ved hjælp af opvarmnings- hhv. afkølingsforholdene for rummene. Desuden er det fra DE 10 2014 102 275 kendt at bestemme indstillingsværdier for reguleringsventiler på basis af opvarmnings- hhv. afkølingsforhold for rummene, og således at gennemføre en hydraulisk balancering.In addition, it is known from EP 1 936 288 B1 to detect a present hydraulic balancing by means of heating respectively. the cooling conditions of the rooms. Furthermore, from DE 10 2014 102 275 it is known to set setting values for control valves on the basis of heating respectively. cooling conditions for the rooms, and thus to carry out a hydraulic balancing.
En ulempe ved de to sidstnævnte løsninger er det træge forhold i sammenligning med mekaniske gennemstrømningsregulatorer, som reagerer direkte på trykforhold, som ændrer sig, og ikke først skal afvente en ændring af sekundærværdier, som eksempelvis ændringen af rumtemperaturen. En yderligere ulempe ved disse løsninger opstår ved anvendelsen af batteridrevne justeringsdrev, som ved hver signifikant differens-trykændring, via reguleringsventilerne skal udføre fornyede justeringsbevægelser, hvorved batterilevetiden reduceres.A disadvantage of the latter two solutions is the sluggish relationship compared to mechanical flow regulators, which respond directly to changing pressure conditions and do not first have to wait for a change of secondary values, such as the change in room temperature. A further disadvantage of these solutions arises from the use of battery-operated adjustment drives, which at each significant differential pressure change, have to perform renewed adjustment movements via the control valves, thereby reducing battery life.
Uafhængigt af de kendte fremgangsmåder til hydraulisk balancering kendes enkelt-rumstemperaturreguleringer, som ved hjælp af en mekanisk eller elektronisk termostat regulerer rumtemperaturen til en forudbestemt indstillingsværdi ved hjælp af et på en reguleringsventil indvirkende drev. Der kendes enkeltrumstemperaturreguleringer, i hvilke der kan indlægges tidsprofiler, med henblik på at definere tidsafhængige opvarmnings- og sænkningsfaser.Independent of the known methods of hydraulic balancing, single-room temperature controls are known, which, by means of a mechanical or electronic thermostat, regulate the room temperature to a predetermined setting value by means of a drive acting on a control valve. Single room temperature controls are known in which time profiles can be inserted in order to define time-dependent heating and lowering phases.
Fra DE 10 2012 002 941 A1 beskrives en fremgangsmåde af den indledningsvis nævnte art til automatisk hydraulisk balancering af forbrugere i et opvarmningsanlæg.From DE 10 2012 002 941 A1, a method of the kind mentioned above is described for automatic hydraulic balancing of consumers in a heating system.
Fra DE 102 56 035 B3 og DE 10 2009 011 506 A1 kendes reguleringsarmaturer, i forbindelse med hvilke trykdifferencen imellem trykområderne før og efter en gennemstrømningsreguleringsenhed i reguleringsarmaturet holdes konstant.From DE 102 56 035 B3 and DE 10 2009 011 506 A1 are known control luminaires, in which the pressure difference between the pressure areas before and after a flow control unit in the control luminaire is kept constant.
Ud fra den kendte teknik er det hensigten med opfindelsen, at tilvejebringe en fremgangsmåde og et system, som muliggør en automatisk hydraulisk balancering af et opvarmnings- og/eller køleanlæg, som også i forbindelse med ændret varme eller kølebehov og dermed ændrede gennemstrømnings- og differenstryk over forbrugerne og reguleringsarmaturerne i de sædvanligvis forekommende belastningstilfælde automatisk, i høj grad uden forsinkelse, differenstryk uafhængigt og permanent tilpasser sig. Supplerende skal en rumtemperaturregulering til forudbestemte indstillingsværdier muliggøres, hvorved såvel den hydrauliske balancering som også rumtemperatur-reguleringen kan ske på enkel måde ved ændring af tværsnittet i gennemstrømningsreguleringsenheden i reguleringsarmaturet.From the prior art it is an object of the invention to provide a method and a system which enables an automatic hydraulic balancing of a heating and / or cooling system, which also in connection with altered heat or cooling requirements and thus changed flow and differential pressures over the consumer and the control fittings in the most common load cases automatically, to a great extent without delay, differential pressure independently and permanently adjusts. In addition, a room temperature control for predetermined setting values must be allowed, whereby the hydraulic balancing as well as the room temperature control can be done in a simple way by changing the cross section of the flow control unit in the control luminaire.
Til opnåelse af dette foreslår opfindelsen en fremgangsmåde, som er kendetegnet ved, at trykdifferencen imellem trykområder før og efter gennemstrømningsreguleringsenheden i reguleringsarmaturerne holdes konstant, at opvarmnings- og/eller afkølingsforholdene for de individuelle rum, ved hjælp af de i rummene detekterede rumtemperaturmåleværdier og en samtidig gennemført tidsmåling, tilvejebringelse af beregningsenheden og sammenlignes med et for hvert rum indlagt temperatur-tidsprofil, og at væskestrømmen igennem de individuelle forbrugere (4) ændres ved ændring af gennemstrømningstværsnittet for gennemstrømningsreguleringsenheden (21) i reguleringsarmaturerne (8), indtil den detekterede rumtemperaturmåleværdi for de individuelle rum stemmer overens med den i tidsprofilet indlagte rumtemperatur-indstillingsværdi, og en hurtigst mulig og samtidig opnåelse af de angivne rumtem-peraturindstillingsværdierfor de individuelle rum opnås. I overensstemmelse med opfindelsen bliver en automatisk hydraulisk balancering opnået, som i alle belastningstilfælde kan gennemføres uden forsinkelse, er integreret i en enkeltrumstemperaturregulering og reducerer justeringscyklusserne for justeringsdrevet, eftersom disse kun udløses ved ændring af rumtemperaturerne, men ikke ved ændrede trykforhold i opvarmnings- og/eller køleanlægget. Supplerende opnås en reduktion af energiforbruget ved en automatisk tilvejebragt, behovstyret fremløbs-temperatur og ved en optimering af pumpeomdrejningstallet for cirkulationspumpen. Desuden bortfalder besværlige rørledningsberegninger, eftersom justeringsværdierne for gennemstrømningsregulatorerne bestemmes automatisk på basis af det faktisk nødvendige volumenstrømningsbehov.In order to achieve this, the invention proposes a method characterized in that the pressure difference between pressure ranges before and after the flow control unit in the control luminaires is kept constant, that the heating and / or cooling conditions of the individual rooms, by means of the room temperature detected values and simultaneous values. carried out time measurement, provision of the calculator and compared with a temperature-time profile for each room, and that the liquid flow through the individual consumers (4) is changed by changing the flow cross-section of the flow control unit (21) in the control luminaires (8) to the detected room temperature temperature. individual rooms correspond to the room temperature setting value entered in the time profile, and a rapid and simultaneous attainment of the specified room temperature setting values for the individual rooms is achieved. In accordance with the invention, an automatic hydraulic balancing is achieved, which in all load cases can be carried out without delay, is integrated into a single room temperature control and reduces the adjustment cycles of the adjustment drive since these are triggered only by changing the room temperatures but not by changing pressure conditions in the heating and / or the cooling system. In addition, a reduction in energy consumption is achieved by an automatically generated, demand-controlled flow temperature and by optimizing the pump speed of the circulation pump. In addition, cumbersome pipeline calculations lapse, as the adjustment values of the flow controllers are automatically determined based on the actual volume flow requirement needed.
Sende- og modtageenhederne er som regel komponenter i justeringsdrevet, ved hjælp af hvilket gennemstrømningstværsnittet ændres. Sendeenheden sender trådbundet eller trådløst løbende den aktuelle indstilling af justeringsdrevet til beregningsenheden, som i sin tur bestemmer og overfører nye indstillingsværdier med hensyn til indstillingen til modtageenheden i justeringsdrevet. Modtageenheden videregiver disse data uden videre ændring til justeringsdrevet. I overensstemmelse med opfindelsen kan detekteringen af rumtemperaturmåle-værdierne ske ved hjælp af rumtemperaturfølere, som er anbragt i de respektive rum, og som kommunikerer med de bearbejdende elementer, især beregningsenheden hhv. sende- og modtageenheden.The transmitting and receiving units are usually components of the adjustment drive by means of which the flow cross section is changed. The transmitting unit sends the current setting of the adjusting drive to the calculating unit, either wired or wireless, which in turn determines and transmits new setting values with respect to the setting to the receiving unit in the adjustment drive. The receiving device transmits this data to the alignment drive without further modification. In accordance with the invention, the detection of the room temperature measurement values can be done by means of room temperature sensors located in the respective rooms and which communicate with the processing elements, in particular the calculator and the like, respectively. the sending and receiving unit.
Reguleringsarmaturet består fortrinsvis af en gennemstrømningsreguleringsventil med et hus, som omfatter i det mindste et indløb og i det mindste et udløb for varmetrans-missionsmediet samt en derimellem anbragt tilslutningsstuds, i hvilken en trykreguleringsindretning er indbygget, som holder trykdifferencen imellem trykområdet før og efter en i tilslutningsstudsen anbragt gennemstrømningsreguleringsenhed konstant. Desuden er der på gennemstrømningsreguleringsenheden tilvejebragt en tværsnitsforanderligt virkende spindel med et justeringsdrev, bestående af en på spindlen virkende forskydnings- eller drejeenhed og sende- og modtageenheden. Via sendeindretningen kan information om forskydnings- eller drejestillingen for spindlen sendes til beregningsenheden, og via modtageenheden kan der modtages indstillingsværdier fra beregningsenheden til forskydnings- eller drejestilling for spindlen. Indstillingsværdierne for de individuelle reguleringsarmaturer sker i afhængighed af opvarmnings- eller afkølingsforhold for de individuelle rum og/eller yderligere parametre, således at alle forbrugere opnår deres behovstyrede volumenstrøm, opvarmnings- eller køleanlægget automatisk balanceres hydraulisk og en rumtemperaturregulering, som er overlejret indstillingsværdierne, foretages i afhængighed af temperaturforskellen imellem rumtemperaturmåleværdien og rumtemperaturindstillingsværdien for de individuelle rum ved ændring af tværsnittet i gennemstrømningsreguleringsenheden i reguleringsarmaturerne.The control luminaire preferably consists of a flow control valve with a housing comprising at least one inlet and at least one outlet for the heat transmission medium as well as an interconnecting plug in which a pressure control device is built which maintains the pressure difference between the pressure area before and after the connection nozzle placed the flow control unit constantly. In addition, a cross-sectional variable spindle is provided on the flow regulating unit with an adjusting drive consisting of a displacement or turning unit acting on the spindle and the transmitting and receiving unit. Via the transmitter, information about the shear or rotational position of the spindle can be sent to the calculator, and via the receiving unit, setting values can be received from the calculator to the displacement or rotational position of the spindle. The setting values for the individual control luminaires are dependent on heating or cooling conditions for the individual rooms and / or additional parameters, so that all consumers achieve their demand-controlled volume flow, the heating or cooling system is automatically hydraulically balanced and a room temperature control which is superimposed with setting values. dependence on the temperature difference between the room temperature measurement value and the room temperature setting value for the individual rooms by changing the cross section of the flow control unit in the control luminaires.
De af alle sendeenheder for reguleringsarmaturerne sendte data bliver modtaget og bearbejdet af beregningsenheden. Forekommer der forskelle i sammenligning mellem opvarmnings- hhv. afkølingsforhold for de individuelle rum indbyrdes, dvs. bliver eksempelvis individuelle rum hurtigere opvarmet end andre, kan der ud fra dette genereres nye indstillingsværdier. Ventiler i rum med hurtigere opvarmningsforhold opnår derefter en kraftigere begrænsning af tværsnittet end rum med langsommere opvarmningsforhold, hvis tværsnit efterfølgende begrænses mindre kraftigt.The data sent by all transmitters for the control luminaires is received and processed by the calculator. There are differences in comparison between heating and heating. cooling conditions for the individual rooms among themselves, ie. For example, if individual rooms are heated faster than others, new setting values can be generated from this. Valves in rooms with faster heating ratios then achieve a more severe limitation of the cross-section than rooms with slower heating ratios, whose cross-sections are subsequently less severely restricted.
Det maksimalt til rådighed stående tværsnit for gennemstrømningsreguleringsenheden bliver først begrænset af den hydrauliske balancering. Rumtemperaturreguleringen reducerer i givet fald dette tværsnit for regulering af rumtemperaturen. Bliver indstillingsværdien for rumtemperaturen overskredet, er gennemstrømningsreguleringsenheden afspærret. Denne afspærring hhv. reduktion af tværsnittet for rumtempera-turregulering påvirker anlægshydraulikken, således at i dette tilfælde bliver nye maksimale tværsnit for gennemstrømningsreguleringsenhederne tilvejebragt af beregningsenheden.The maximum available cross section of the flow control unit is first limited by the hydraulic balancing. If necessary, the room temperature control reduces this cross-section for room temperature control. If the room temperature setting value is exceeded, the flow control unit is shut off. This shut-off, respectively. Reducing the cross section for room temperature control affects the plant hydraulics, so that in this case new maximum cross sections for the flow control units are provided by the calculator.
Sendeenheden transmitterer de tilsvarende data via et datakabel eller trådløst, eksempelvis via radio, på digital form til beregningsenheden.The transmitting unit transmits the corresponding data via a data cable or wireless, for example via radio, in digital form to the calculator.
Den tilhørende tidsmåling sker i beregningsenheden. Eksempelvis bliver beregningsenheden omsat som indlejret system med mikroprocessor og lager, hvor, på basis af frekvensen for en krystal, tidsafstande kan måles og bearbejdes.The associated time measurement is done in the calculator. For example, the calculator is converted into a microprocessor and memory embedded system where, based on the frequency of a crystal, time distances can be measured and processed.
Desuden er det foretrukkent foreskrevet, at i det mindste et reguleringsarmatur opnår den maksimale tværsnitsåbning for gennemstrømningsreguleringsenheden.In addition, it is preferably provided that at least one control luminaire achieves the maximum cross-sectional opening of the flow control unit.
Fremløbstemperaturen kan sænkes maksimalt (ved opvarmning), henholdsvis forøges maksimalt (ved afkøling), så længe alle rum stadig opnår deres indstillingsværdier for rumtemperaturer, og indtil tværsnittet for gennemstrømningsreguleringsenheden i reguleringsarmaturet når den maksimale tværsnitsåbning, således at den hydrauliske modstand bliver minimal.The flow temperature can be lowered maximum (by heating) or increased by maximum (by cooling), as long as all rooms still reach their setpoint values for room temperatures, and until the cross-section of the flow control unit in the control unit reaches the maximum cross-sectional opening, so that the hydraulic resistance becomes minimal.
Desuden er det foretrukkent foreskrevet, at for i det mindste et reguleringsarmatur foreskrives det maksimale og/eller minimale gennemstrømningstværsnit af beregningsenheden.In addition, it is preferably provided that for at least one control luminaire, the maximum and / or minimum flow cross-section of the calculator is prescribed.
Den beskrevne tilpasning af fremløbstemperaturen medfører en energibesparelse, eftersom virkningsgraden for varmegeneratorer, såsom varmepumper, er større ved lavere fremløbstemperaturen og at ved lavere fremløbstemperaturer er varmetabene i rørledningerne, lagre og lignende mindre. Fremløbstemperaturen kan imidlertid ikke tilpasses vilkårligt. Yderligere kan fremløbstemperaturen kun tilpasses, indtil de tidsafhængige indstillingstemperaturer for de individuelle rum også opnås. Angivelsen af den minimale forskydnings- eller drejestilling og dermed det maksimale eller minimale gennemstrømningstværsnit kan især i forbindelse med træge forbrugere, som eksempelvis gulvvarmeanlæg, være en fordel, med henblik på at modvirke en for kraftig rumtemperaturssvingning.The described adaptation of the flow temperature results in an energy saving, since the efficiency of heat generators, such as heat pumps, is greater at lower flow temperatures and that at lower flow temperatures the heat losses in the pipelines, bearings and the like are less. However, the flow temperature cannot be arbitrarily adjusted. Furthermore, the flow temperature can only be adjusted until the time-dependent setting temperatures for the individual rooms are also obtained. The indication of the minimum shear or rotational position and thus the maximum or minimum flow cross-section can be advantageous especially in connection with slow consumers, such as underfloor heating systems, in order to counteract excessive room temperature fluctuation.
Fortrinsvis er det desuden foreskrevet, at beregningsenheden udveksler data med varme- og/eller kuldegeneratorer, og at disses forøger eller sænker varme- eller kuldegenereringen, indtil de indlagte temperatur-tidsprofiler for rummene opnås. I det enkleste tilfælde får varme- eller kuldegeneratoren kun en ny fremløbstemperatur foreskrevet af beregningsenheden. Det er imidlertid også muligt, at varme- eller kuldegeneratoren supplerende transmitterer sin aktuelle fremløbstemperatur til beregningsenheden.In addition, it is further provided that the calculator exchange data with heat and / or cold generators and that they increase or decrease the heat or cold generation until the entered temperature-time profiles for the rooms are obtained. In the simplest case, the heat or cold generator only gets a new flow temperature prescribed by the calculator. However, it is also possible that the heat or cold generator additionally transmits its current flow temperature to the calculator.
Desuden er det foretrukkent foreskrevet, at beregningsenheden udveksler data med cirkulationspumpen, og at denne forøger eller sænker sin ydelse, indtil de indlagte temperatur-tidsprofiler for rummene opnås.In addition, it is preferred that the calculator exchange data with the circulation pump and that it increases or decreases its performance until the entered temperature-time profiles for the rooms are obtained.
Cirkulationspumpen modtager i enkleste tilfælde en angivelse med hensyn til pumpeomdrejningstallet. Det er imidlertid også tænkeligt, at cirkulationspumpen transmitterer sit aktuelle omdrejningstal til beregningsenheden.In the simplest case, the circulation pump receives an indication of the pump speed. However, it is also conceivable that the circulation pump transmits its current speed to the calculator.
Fortrinsvis er det desuden foreskrevet, at der ved hjælp af en fremløbs- og returløbs-temperaturdetektion på de til de respektive forbrugere førende rørledninger i rørledningssystemet, ved hjælp af beregningsenheden, som bearbejder de via sende- og modtageenheden modtagne temperaturdata, forudsiges et opvarmnings- eller afkølingsforhold for de individuelle rum, og den automatiske hydrauliske udligning for de individuelle forbrugere gennemføres ved hjælp af denne forudsigelse.Preferably, it is furthermore provided that by means of a flow and return temperature detection on the pipelines leading to the respective consumers in the pipeline system, by means of the calculating unit which processes the temperature data received via the sending and receiving unit, a heating or cooling conditions for the individual compartments and the automatic hydraulic equalization for the individual consumers is carried out using this prediction.
Hertil er det foreskrevet, at der i hvert fremløb og returløb for enhver forbruger eller en gruppe af forbrugere er anbragt en temperaturføler, som detekterer temperaturerne og overfører disse til beregningsenheden, i hvilken disse temperaturer så atter sammenlignes med et i lageret i beregningsenheden indlagt forbrugsmønster eller datamønster, og reguleringsenheden efterfølgende overfører tilsvarende justeringsordrer til justeringsdrevene til spindeljustering (gennemstrømningsregulering). I krav 7 er angivet et system til automatisk hydraulisk balancering af forbrugere i et opvarmnings- og/eller køleanlæg, i hvilket fremgangsmåden ifølge krav 1-6 gennemføres. Her er især foreskrevet, at der som reguleringsarmatur er indbygget en gennemstrømningsreguleringsventil bestående af et hus med i det mindste et indløb og i det mindste et udløb for varmetransmissionsmediet og en imellem disse anbragt tilslutningsstuds, i hvilken en trykreguleringsindretning er indbygget, som holder trykdifferencen imellem trykområderne før og efter en i tilslutningsstudsen anbragt gennemstrømningsreguleringsenhed konstant, samt udstyret med en spindel på gennemstrømningsreguleringsenheden, som virker forandrende på gennemstrømningstværsnittet, og et justeringsdrev, bestående af en på spindlen virkende forskydnings- eller drejeenhed og en elektrisk eller elektronisk sende- og modtageenhed, idet der ved hjælp af sendeindretningen i sende- og modtageenheden sendes informationer eller data om den aktuelle forskydnings- eller drejestilling for spindlen til beregningsenheden, som i denne bearbejdes og omformes til indstillingsværdier, som sendes til modtageindretningen i sende- og modtageenheden, og ved hjælp af hvilke indstillingen af forskydnings- eller drejestillingen for spindlen gennemføres ved hjælp af forskydningseller drejeenheden.To this end, it is required that in each flow and return flow for every consumer or group of consumers a temperature sensor is detected which detects the temperatures and transmits them to the calculator, in which these temperatures are again compared with a consumption pattern stored in the storage unit of the calculator. data pattern, and the control unit subsequently transmits corresponding adjustment orders to the spindle alignment adjustment drives (flow control). Claim 7 provides a system for automatic hydraulic balancing of consumers in a heating and / or cooling system, in which the method according to claims 1-6 is carried out. In particular, it is stipulated that a flow control valve is provided as a control fitting consisting of a housing with at least one inlet and at least one outlet for the heat transmission medium and a connection nozzle disposed therein, in which a pressure control device is housed which maintains the pressure difference between before and after a flow regulating unit permanently disposed in the connection stud, as well as equipped with a spindle on the flow regulating unit which changes on the flow cross section and an adjusting drive consisting of a displacement or turning unit acting on the spindle and an electric or electronic transmitting and receiving unit by means of the transmitting device in the sending and receiving unit, information or data about the current displacement or turning position of the spindle is sent to the calculating unit, which is processed and converted into setting values which are sent to the receiver. in the transmitting and receiving unit, and by means of which the adjustment of the shaft or pivot position of the spindle is carried out by means of the shear or pivot unit.
Desuden kan det i den forbindelse være foreskrevet, at der i de individuelle rum er anbragt rumtemperaturfølere.In addition, it may be prescribed in this connection that room temperature sensors are arranged in the individual rooms.

Further, the flow control valve 10 has a spindle 16 on the flow control unit 21, which acts cross-sectionally changing, and an adjusting drive 17 thereto, which consists of a displacement or turning unit 18 acting on the spindle 16 and is coupled to a transmitting and receiving unit 19. Information is sent via the transmitting device. whether the actual displacement or turning position of the spindle 16 is transmitted and sent to the calculator 9, while setting values are received via the receiving device from the calculating unit 9 to the displacement or turning position of the spindle 16, and an adjustment of the flow cross section is effected by movement of the spindle 17 by means of the adjustment drive. .
Efterfølgende beskrives det komplette forløb af fremgangsmåden inklusive signaloverføringen og signaldetektionen.Subsequently, the complete process of the method including signal transmission and signal detection is described.
Trinl: SignaldetektionStep: Signal detection
Rumtemperaturfølerne 20 måler den aktuelle rumtemperatur i de respektive rum. Justeringsdrevet 17 detekterer den aktuelle forskydnings- hhv. drejestilling, og således stillingen for spindlen 16.The room temperature sensors 20 measure the current room temperature in the respective rooms. The adjusting drive 17 detects the current offset, respectively. turning position, and thus the position of the spindle 16.
Trin 2: Datatransmission til beregningsenhed 9Step 2: Data Transmission to Calculator 9
Rumtemperaturfølerne 20 og sendeenhederne i sende- og modtageenhederne i sende- og modtageenhederne 19 i justeringsdrevene 17 transmitterer de detekterede værdier til beregningsenheden 9, enten kabelbundet eller trådløst, idet rum-temperaturfølerne 20 trådbundet eller trådløst også kan sende til modtageenheden i sende- og modtageenheden 19 i justeringsdrevet 17, som så i sin tur transmitterer rum-temperaturmåleværdier til beregningsenheden.The room temperature sensors 20 and transmit units of the transmit and receive units of the transmit and receive units 19 of the adjustment drives 17 transmit the detected values to the calculator 9, either wired or wireless, the room temperature sensors 20 wired or wireless also transmit to the receiving unit of the transmit and receive unit 19 in the adjustment drive 17, which in turn transmits room temperature measurement values to the calculator.
Trin 3: Bestemmelse af opvarmningsforholdetStep 3: Determine the heating ratio
Beregningsenheden 9 bestemmer karakteristiske parametre, eksempelvis temperaturstigningen pr. tidsenhed, for opvarmnings- hhv. afkølingsforhold for alle rum og sammenligner disse indbyrdes samt de individuelle rumtemperaturmåleværdier med de tilhørende rumtemperaturindstillingsværdier.The calculator 9 determines characteristic parameters, e.g. unit of time, for heating or heating. cooling conditions for all rooms and compares them to each other as well as the individual room temperature measurement values with the corresponding room temperature setting values.
Fordelagtigt kan også være en hensyntagen til ældre, lagrede værdier med hensyn til opvarmnings- og afkølingsforhold for rummene.Also advantageous may be the consideration of older, stored values in terms of heating and cooling conditions of the rooms.
Trin 4: Beregning af nye indstillingsværdier for forskydnings-/drejestilling for justeringsdrevet 17Step 4: Calculation of new setting values for offset / turning position for the adjustment drive 17

Rumtemperaturindstillingsværdien er enten indlagt centralt i beregningsenheden 9 for hvert enkelt rum, eller bliver af eksterne indstillingsværdigivere for de respektive rum transmitteret til beregningsenheden 9, hvor indstillingsværdigiverne i givet fald kan være sammenbyggede med de tilsvarende rumtemperaturfølere 20 i en montageenhed.The room temperature setting value is either centralized in the calculator 9 for each room, or transmitted by external setting values for the respective rooms to the calculator 9, where the setting value sensors may be combined with the corresponding room temperature sensors 20 in a mounting unit.
Trin 5: Datatransmission til modtageenheden i sende-/modtageenheden 19Step 5: Data transmission to the receiving unit in the sending / receiving unit 19
Beregningsenheden 9 transmitterer de nye indstillingsværdier til modtageenheden i sende- og modtageenheden 19 i justeringsdrevet 17. Dette betjenes og indstilles i overensstemmelse hermed.The computing unit 9 transmits the new setting values to the receiving unit in the transmitting and receiving unit 19 in the adjustment drive 17. This is operated and adjusted accordingly.
