Emnet for nærværende frembringelse er et satellitarrangement for centralvarme ellerfor fjernvarme i overensstemmelse med den indledende del af hovedkravet.The subject of the present invention is a satellite arrangement for central heating or for district heating in accordance with the preamble of the main requirement.

Specifikt angår frembringelsen et hydraulisk satellitarrangement til varmvands¬fremstillingssystemer, til lejligheds- eller lignende-varmesystemer, eller til fremstillingaf sanitært vand, hvor fremstillingen af opvarmningsfluidet finder sted fjernt fra denopvarmede lejlighed eller fra det sted, hvor det sanitære varme vand anvendes. Isådanne systemer, som de, som er kendt som fjernvarme, finder fremstillingen afopvarmningsfluidet sted i en fjerntliggende position, ved hjælp af de mest varierendeteknikker, inklusive varmegenvinding fra affaldsbortskaffelsessystemer, via en sandvandopvarmning i beholdere, som er decentraliserede i forhold til de lejligheder ellerlignende, hvor sådant varmt vand anvendes.Specifically, the production relates to a hydraulic satellite arrangement for hot water production systems, for apartment or similar heating systems, or for the production of sanitary water, where the production of the heating fluid takes place remote from the heated apartment or from the place where the sanitary hot water is used. Such systems, such as those known as district heating, produce the heating fluid in a remote position, using the most varied techniques, including heat recovery from waste disposal systems, via a sand water heating in containers which are decentralized to the apartments or the like, where such hot water is used.

Hydrauliske satellitter kendes, som gør det muligt at fremstille sådant varmt vand tilanvendelse i en fjerntliggende position til opvarmning af lejligheder eller lignende, ellertil sanitær anvendelse. Generelt omfatter sådanne indretninger eller systemer enstruktur, som indeholder funktionselementer, som er egnede til at tilvejebringe ensanitær vandstrømning i en varmeveksler, som den tilføres, og hvor opvarmnings¬fluidet (fremstillet i en fjerntliggende position) også strømmer. En sådan regulatoromfatter interne ventiler, som er egnede til at regulere strømningen af opvarmnings¬fluidet for at styre og regulere temperaturen for det sanitære vand og for at anvendedette i lejligheden eller lignende.Hydraulic satellites are known which enable such hot water to be used in a remote location for heating apartments or similar, or for sanitary use. Generally, such devices or systems comprise a structure containing functional elements suitable for providing ensanitary water flow in a heat exchanger to which it is supplied and wherein the heating fluid (produced in a remote position) also flows. Such a regulator comprises internal valves which are suitable for regulating the flow of the heating fluid to control and regulate the temperature of the sanitary water and for use in the apartment or the like.

I de kendte hydrauliske systemer af den nævnte type foreligger der forskelligekomponenter, inklusive strømningsregulatorer og ventiler, som styres elektrisk ellerunder alle omstændigheder styres af eksterne indretninger (eksempelvis entermostat), som er elektrisk styrede. Sådanne systemer eller satellitter implementeresved, i en kasselignende struktur, at installere rørføringer, som gør det muligt atmodtage opvarmningsfluidet fra en fjerntliggende position, og at returnere dette til detanlæg, som fremstiller sådant opvarmningsfluid, en pumpe, én eller adskilligesikkerhedsventiler, og de komponenter, som er nødvendige for at styre afgivelsen afvand til radiatorer eller haner i den nævnte lejlighed eller lignende. Sådannekomponenter samles indvendigt i den kasselignende struktur som en funktion af deaktuelle behov, hvilket medfører en forlængelse af installationstiderne i lejligheden,eller lignende, hvor strukturen skal anvendes.In the known hydraulic systems of the said type, there are various components, including flow regulators and valves, which are electrically controlled or in any case controlled by external devices (eg entermostat) which are electrically controlled. Such systems or satellites are implemented, in a box-like structure, to install piping that allows the heating fluid to be received from a remote location and to return it to facilities producing such heating fluid, a pump, single or multiple safety valves, and the components which are required to control the discharge of water to radiators or taps in said apartment or the like. Such components are assembled internally in the box-like structure as a function of out-of-date needs, resulting in an extension of the installation times in the apartment or the like where the structure is to be used.

Yderligere er de kendte løsninger under alle omstændigheder komplekse og dyre.Furthermore, the known solutions are in any case complex and expensive.

Et formål med nærværende frembringelse er at tilbyde et satellitarrangement, som erforbedret i forhold til de kendte løsninger og som er umiddelbart tilgængelige tilinstallation i en lejlighed eller lignende.An object of the present invention is to provide a satellite arrangement which is improved in relation to the known solutions and which is readily available for installation in an apartment or the like.

Et andet formål er at tilbyde et satellitarrangement, som er i stand til, på kort tid, atmodtage, eller ikke et differentialtryksregulatorelement, når som helst dette ernødvendigt.Another object is to provide a satellite arrangement capable of receiving, in a short time, or not a differential pressure regulator element, whenever necessary.

Et yderligere formål er at tilbyde et satellitarrangement af den ovenfor nævnte type,som er i stand til at modtage det nævnte regulatorelement, uden at være tvunget til at"rekonstruere" det hydrauliske system, som foreligger indvendigt i satellitlegemet.A further object is to provide a satellite arrangement of the above-mentioned type capable of receiving the said control element, without being forced to "reconstruct" the hydraulic system which is inside the satellite body.

Yderligere formål er at tilbyde et satellitarrangement, som er pålideligt i brug og somtilbyder en høj grad af sikkerhed i hver af dettes anvendelser.Further purposes are to provide a satellite arrangement which is reliable in use and which offers a high degree of security in each of its uses.

Disse formål og andre, som vil fremgå for en fagmand inden for området, opnås medet satellitarrangement i overensstemmelse med de vedhæftede krav.These objects and others, which will be apparent to those skilled in the art, are achieved by satellite arrangement in accordance with the appended claims.

For en bedre forståelse af nærværende frembringelse, er de følgende tegningervedhæftet alene forforklarende og ikke begrænsende formål, hvor: fig. 1 viser et frontbillede af et satellitarrangement udformet i overens¬ stemmelse med frembringelsen, idet nogle af dettes dele er udeladt afhensyn til forenkling; fig. 2 viser et perspektivisk billede af satellitarrangementet i fig. 1; fig. 3 viser et langsgående snit i en komponent i satellitarrangementet i fig. 1; fig. 4 viser et delvist tværsnitsperspektivisk billede af komponenten i fig. 3; og fig. 5 viser et tværsnit i en ventil monteret i satellitarrangementet i fig. 1.For a better understanding of the present invention, the following drawings are for explanatory and non-limiting purposes only, in which: 1 shows a front view of a satellite arrangement designed in accordance with the production, some of its parts being omitted for simplification purposes; FIG. 2 is a perspective view of the satellite arrangement of FIG. 1; FIG. 3 is a longitudinal section of a component of the satellite arrangement of FIG. 1; FIG. 4 is a partial cross-sectional perspective view of the component of FIG. 3; and FIG. 5 is a cross-sectional view of a valve mounted in the satellite arrangement of FIG. First

Under henvisning til de nævnte figurer, er et hydraulisk satellitarrangement (eller blot,"satellit") for centralvarme eller til fjernvarme generelt identificeret med henvisnings¬tallet 1 og i fig. 1 og 2 er i det mindste et frontpanel fjernet derfra, med henblik på athave visuel adgang til dets indvendige komponentdele. Et sådant satellitarrangementeller blot satellit 1 omfatter en kasselignende struktur 2 med en sidevæg 3 (den øvre side i figurerne), en sidevæg 4 (den højre side i figurerne), en sidevæg 5 (den nedreside i figurerne) og en sidevæg 6 (den venstre side i figurerne) og et bagsidelukkendeplan eller panel 7. Sådanne vægge 3-6 og panel 7 (sammen med frontpanelet, somikke er vist på figurerne) afgrænser et indvendigt rum 9 i satellitten 1, hvori et antalfunktionselementer er placerede, inklusive en pumpe 10 fuldstændigt med sine egnebeslag, reguleringsventiler 12 og 13 og en sædvanlig termostatisk omskifter 14, alle afdisse forbundet med passende rørføring (generelt identificeret med henvisningstallet16). Sidstnævnte omfatter især en indløbs- eller fremløbsrørføring 18 og en udløbs¬eller returrørføring 17: rørføringen 18 er forbundet med en sædvanlig første (medgevind forsynet) rørfitting 21 til at forbinde satellitten 1 og en indløbs- eller fremløbs-kanal (ikke vist på figurerne), som fremfører opvarmningsfluidet fra et anlæg, hvorsådant fluid fremstilles i en vis afstand fra satellitten 1 (følgelig "fjernt" derfra) ikke vistpå figurerne. Modsvarende er rørføringen 17 forbundet med en sædvanlig andenrørfitting 20 for at forbinde satellitten med en udløbs- eller returkanal (ikke vist påfigurerne), hvori fluidet strømmer tilbage til det ovennævnte fjerntliggende anlæg.Referring to said figures, a hydraulic satellite arrangement (or simply, "satellite") for central heating or for district heating is generally identified by the reference numeral 1 and in FIG. 1 and 2, at least one front panel is removed therefrom to provide visual access to its internal component parts. Such a satellite arrangement or just satellite 1 comprises a box-like structure 2 with a side wall 3 (the upper side of the figures), a side wall 4 (the right side of the figures), a side wall 5 (the lower side of the figures) and a side wall 6 (the left side). side walls of the figures) and a rear cover plane or panel 7. Such walls 3-6 and panel 7 (together with the front panel, not shown in the figures) define an interior space 9 of the satellite 1 in which a plurality of function elements are located, including a pump 10 completely with its suitable fittings, control valves 12 and 13 and a usual thermostatic switch 14, all of these connected with appropriate piping (generally identified by the reference number16). The latter in particular comprises an inlet or outlet pipe 18 and an outlet or return pipe 17: the pipe 18 is connected to a conventional first (coiled thread) pipe fitting 21 to connect the satellite 1 and an inlet or outlet channel (not shown in the figures). which feeds the heating fluid from a plant whereby fluid is produced at a certain distance from the satellite 1 (hence "distant" therefrom) not shown in the figures. Similarly, the pipe guide 17 is connected to a conventional second pipe fitting 20 to connect the satellite to an outlet or return channel (not shown in the figures), in which the fluid flows back to the aforementioned remote system.

Sådanne første og anden rørfittings 20 og 21 er knyttet til væggen 3 i strukturen 2 i deteksempel, som er skitseret i figurerne.Such first and second pipe fittings 20 and 21 are attached to the wall 3 of the structure 2 of the example, which is outlined in the figures.

Andre sædvanlige rørfittings 22, 23, 24 og 25 er knyttet til væggen 5 i strukturen 2 i deteksempel, som er skitseret i figurerne, og forbinder sidstnævnte med rørfittings (ikkevist i figurerne), som fordeler det indkommende fluid til et opvarmningsanlæg eller til etsanitært vandanlæg (ikke vist på figurerne) i en lejlighed eller lignende (omfattende ételler adskillige rum), hvori satellitten 1 er inkluderet, som en funktion af de aktuellebehov.Other conventional pipe fittings 22, 23, 24 and 25 are attached to the wall 5 of the structure 2 of the example, outlined in the figures, and connect the latter to pipe fittings (not shown in the figures) which distribute the incoming fluid to a heating system or to a sanitary water system. (not shown in the figures) in an apartment or the like (comprising several rooms), in which the satellite 1 is included, as a function of current needs.

De ovenfor nævnte funktionelle elementer er sædvanligvis til stede indvendigt i ensatellit af en type svarende til den ifølge nærværende frembringelse. Sådanneelementer styres af en styreenhed, ikke vist på figurerne, som styrer dennes funktionsom en funktion af brugerens behov eller krav, i i og for sig kendte modi.The above-mentioned functional elements are usually present internally in ensatellite of a type similar to that of the present invention. Such elements are controlled by a control unit, not shown in the figures, which controls its operation as a function of the user's needs or requirements, in modes known per se.

Det er kendt, at brugersatellitterne til centralvarme eller til fjernvarme, skal være istand til at fungere under ekstremt forskellige betingelser. Eksempelvis kan én ogsamme satellit anvendes i et system, som har mindre end seks brugere og etfremløbstryk for cirkulationspumperne, som er mindre end seks meter (60 kPa) eller i udstrakte fjernvarmenetværk, hvor fremløbstrykket for pumpen sågar kan overskride10 bar (1 MPa).It is known that the user satellites for central heating or for district heating must be capable of operating under extremely different conditions. For example, one and the same satellite can be used in a system that has less than six users and a single flow pressure for the circulation pumps less than six meters (60 kPa) or in extended district heating networks where the pump flow pressure can even exceed 10 bar (1 MPa).

Følgelig, med henblik på at en sådan satellit skal fungere optimalt, især i tilfælde afdennes anvendelse i et system, som omfatter fremløbstryk på op til 6 bar, er detanbefalelsesværdigt at tilføje en differentialtryksregulator dertil. Satellitten ifølgenærværende frembringelse er forudindstillet til at modtage en sådan regulator eller atfungere uden denne, som en funktion af de aktuelle behov.Accordingly, in order for such a satellite to function optimally, especially in the event of its use in a system comprising supply pressures of up to 6 bar, it is recommended to add a differential pressure regulator thereto. The satellite of the present generation is preset to receive such a controller or operate without it, as a function of current needs.

Med dette formål omfatter satellitten 1 (fortrinsvis, men ikke nødvendigvis) i rummet 9et legeme 30 forbundet, via åbningerne 30A og 30B, med rørføringerne 18 og 17 ogfølgelig med den første indløbsrørfitting 21 og med den anden udløbsrørfitting 20 ogmed et sæde 31, som er egnet til at modtage en sædvanlig trykregulator 32, somomfatter et fjederforspændt bevægeligt membranelement 33 og et eget filter. I denudførelsesform, som er skitseret i figurerne, er sædet 31 forbundet med indløbs¬rørføringen 18 og trykregulatoren 32 fungerer på det fluid, som passerer igennem denanden indløbsrørfitting 21. Specifikt bevæger sådant fluid, som indføres i legemet 30, ioverensstemmelse med pilen W i fig. 4.For this purpose, the satellite 1 (preferably, but not necessarily) in the space 9 of the body 30 is connected, via the openings 30A and 30B, to the pipes 18 and 17 and, of course, to the first inlet pipe fitting 21 and to the second outlet pipe fitting 20 and to a seat 31 which is suitable for receiving a conventional pressure regulator 32 which includes a spring biased movable diaphragm member 33 and its own filter. In the embodiment outlined in the figures, the seat 31 is connected to the inlet pipe guide 18 and the pressure regulator 32 acts on the fluid passing through the inlet pipe fitting 21. Specifically, such fluid introduced into the body 30 moves in accordance with the arrow W in FIG. . 4th

Trykregulatoren 32 er, via en rørføring 37 med reduceret tværsnit, forbundet med enkanal 38, som er forbundet med åbningen 30A, som er forbundet med returrørføringen17, nedstrøms i forhold til sidstnævnte. Via denne rørføring 37 bringes trykket forreturneringen af fluid (udløb fra rørfittingen 20) tilbage på membranen 33 itrykregulatoren 32, medens trykket fra fluidet, som foreligger i indløbsrørføringen 18,bringes tilbage på bagsiden 33A af membranen 33 via en indvendig kanal 40 i legemet30, hvori en lukker 41 for regulatoren 32 bevæger sig. Som en funktion af strømnings¬hastigheden for opvarmningsfluidet, som begæres af satellitten, reguleres positionenfor lukkeren til at holde differentialtrykket nedstrøms for legemet 30, mere specifiktimellem rørføringerne 17 og 18, konstant på en forudbestemt værdi.The pressure regulator 32 is connected, via a conduit 37 of reduced cross-section, to a single channel 38 which is connected to the opening 30A which is connected to the return pipe 17, downstream of the latter. Via this pipe guide 37, the pressure of the business annulus of fluid (outlet of the pipe fitting 20) is returned to the diaphragm 33 in pressure regulator 32, while the pressure from the fluid present in the inlet pipe 18 is returned to the back side 33A of the diaphragm 33 via an internal channel 40 in the body 30, wherein a shutter 41 for the controller 32 moves. As a function of the rate of flow of the heating fluid demanded by the satellite, the position of the shutter to keep the differential pressure downstream of the body 30, more specifically between the pipes 17 and 18, is constantly adjusted to a predetermined value.

Trykregulatoren 32 omfatter et legeme 44 med en del 45, som er egnet til at bliveanbragt eller monteret, via en åbning 46, i sædet 31, hvor den fastlåses med letudløselige, fastholdende organer, eksempelvis låsefjedre 47, som omslutter delen 45.Et filter kan installeres omkring en sådan del 45. Følgelig, ved montering af satellitten1, hvis tilstedeværelsen af regulatoren 32 ikke kræves, vil legemet 30 have proppersvarende til åbningen 46 i sædet 31 hhv. i kanalen 38, medens den heller ikke vil omfatte, udover regulatoren 32, rørføringen 37. Hvis en sådan regulator kræves, ellerden ikke er indsat i satellitten 1 selv efter dennes installation (og under denneslevetid), fjernes de nævnte propper og den nævnte rørføring og regulatoren 32forbindes med legemet 30. Alt dette på en hurtig og simpel måde for den, som eransvarlig for at modificere satellitten.The pressure regulator 32 comprises a body 44 having a portion 45 suitable for being mounted or mounted, through an opening 46, in the seat 31 where it is locked by easily releasable retaining means, e.g., lock springs 47 which enclose the portion 45. Accordingly, in mounting the satellite1, if the presence of the controller 32 is not required, the body 30 will have plugs corresponding to the aperture 46 in the seat 31, respectively. in the channel 38, while it will not include, besides the controller 32, the piping 37. If such a controller is required or not inserted into the satellite 1 even after its installation (and during its lifetime), the said plugs and the said piping are removed and the controller 32 is connected to the body 30. All this in a quick and simple manner for the person responsible for modifying the satellite.

Ifølge en yderligere foretrukken udførelsesform, omfatter satellitten 1 en sikkerheds¬ventil 49 (som er i stand til at afbryde fluidet hvis dette er nødvendigt, og som følgeligudfører en sikkerhedsfunktion), som er velkendt, men indsat i en forudbestemt positioni satellitten. Med dette formål er en rørfitting 50 anbragt ved udløbet fra en regulerings¬ventil 12, medens et rør 51 er anbragt ved udløbet fra røret 18. Ventilen 49 (med enmembran 52) af en type med forbindelser 53, 54 anbragt på en sådan måde, at dedanner en vinkel på 90° fra hinanden, kan monteres derpå, hvis dette anses fornødvendigt.According to a further preferred embodiment, the satellite 1 comprises a safety valve 49 (which is capable of interrupting the fluid if necessary, and which consequently performs a safety function), which is well known but inserted in a predetermined position in the satellite. For this purpose, a pipe fitting 50 is disposed at the outlet of a control valve 12, while a pipe 51 is disposed at the outlet of the pipe 18. The valve 49 (with single diaphragm 52) of a type with connections 53, 54 is disposed in such manner. deducing an angle of 90 ° from each other may be mounted thereon if deemed necessary.

Ventilen 49 er en magnetventil 56 og passer perfekt på det hydrauliske arrangement afreguleringsventilen 12. Ventilen har en åbne-lukke funktion og aktiveres af styre¬enheden for satellitten via en PWM (pulsbreddemodulation) styring: dennedriftsmetode gør det muligt i væsentlig grad at reducere den effekt, som afgives ispolen til en brøkdel af et sekund fra starten af ventilåbningsstyringen.The valve 49 is a solenoid valve 56 and fits perfectly on the hydraulic arrangement of the regulating valve 12. The valve has an open-closing function and is activated by the satellite control unit via a PWM (pulse width modulation) control: this operation method significantly reduces the power , which is delivered to the ice pole for a fraction of a second from the start of the valve opening control.

Skulle netforsyningen svigte, kan den nævnte enhed ikke længere styrestrømningerne og temperaturen for systemet, som kan nå meget høje værdier, som eri stand til at beskadige selve systemet eller sågar udgør en trussel for sikkerheden,tilstedeværelsen af den (normalt lukkede) ventil sikrer automatisk lukningen afindgangsåbningen for opvarmningsfluidet.Should the mains supply fail, the said unit can no longer control the control currents and the temperature of the system, which can reach very high values which are capable of damaging the system itself or even poses a threat to the safety, the presence of the (normally closed) valve ensures automatic closing. the outlet opening for the heating fluid.

Yderligere, hvis den elektroniske styringsenhed eller en temperaturføler fejler, afbryderen yderligere, redundant termostatisk føler (af mekanisk type), som ikke er vist påfigurerne, kredsløbet for spolen 56 og for ventilen, hvorved den standser opvarmnings¬strømningen. Denne funktion er særlig fordelagtig (og nødvendig) i tilfælde af en panel(eller gulv) opvarmning, medens den ikke anvendes i systemer, som omfattervægmonterede radiatorer.Further, if the electronic control unit or a temperature sensor fails, the circuit breaker further redundant thermostatic (mechanical type) sensor, not shown in the figures, the circuit for the coil 56 and the valve, thereby stopping the heating flow. This feature is particularly advantageous (and necessary) in the case of panel (or floor) heating, while not used in systems including wall mounted radiators.

Ventilen er servoassisteret: spolen 56Afor magnetventilen åbner en meget lille åbning57, som tillader fluidet at strømme fra et kammer 58 placeret på en side af fluidindløbsforbindelsen 54, imod et kammer i forbindelse med forbindelsen 53 og, vedat påvirke membranen 52, at åbne ventilen. Sædvanligvis, idet spolen ikke eraktiveret, holdes ventilen lukket af en svag fjeder (ikke vist på figurerne), som påvirkermembranen, og af trykket af fluidet, på den "lukkede" side af membranen, som nårfrem til denne side via et lille hul (eller kalibreret hul) 60 udskåret i midten afmembranen.The valve is servo assisted: the coil 56Afor the solenoid valve opens a very small opening57 which allows the fluid to flow from a chamber 58 located on one side of the fluid inlet connection 54, against a chamber in connection with the connection 53 and, by actuating the diaphragm 52, to open the valve. Usually, with the coil not actuated, the valve is held closed by a weak spring (not shown in the figures), such as the actuating membrane, and by the pressure of the fluid, on the "closed" side of the diaphragm which extends to this side via a small hole (or calibrated hole) 60 cut into the center of the diaphragm.

Med henblik på at forhindre urenheder i fluidet i at stoppe dette lille hul, er et lillerustfrit stål trådnetfilter 61 placeret i midten af en lukker 62 for ventilen 49.In order to prevent impurities in the fluid from stopping this small hole, a light stainless steel wire mesh filter 61 is located in the center of a shutter 62 for valve 49.

Også i dette tilfælde, som i forbindelse med trykregulatoren 32, er ventilen 49 enteninstalleret eller ikke. I sidstnævnte tilfælde er røret 51 forbundet direkte med ventilen12.Also in this case, as in the case of pressure regulator 32, valve 49 is either installed or not. In the latter case, the tube 51 is connected directly to the valve12.

I en variant er den første og anden rørfitting 21 og 20 definerede ved åbningerne 30Aog 30B i legemet 30.In one variant, the first and second pipe fittings 21 and 20 are defined at the openings 30A and 30B of the body 30.

Satellitten 1 udformet i overensstemmelse med nærværende frembringelse kansuppleres med komponenter, som let kan indsættes deri, som en funktion af deaktuelle krav. Alt dette ved operationer, som er hurtige at udføre af en installatør.The satellite 1 formed in accordance with the present invention is coupled with components which can be easily inserted therein as a function of out-of-date requirements. All this is done by operations that are quick to perform by an installer.
