Description

DK 97 00137 U3DK 97 00137 U3

Den foreliggende opfindelse angår en tilslutningsenhed for tilslutning af varmeafgiverelementer for gulvvarme, i centralvarmeanlæg.BACKGROUND OF THE INVENTION The present invention relates to a connection unit for connecting floor heat exchanger elements in central heating systems.

Ved traditionelle tostrengede centralvarmeanlæg ledes det opvarmede vand til de enkelte varmeafgivere såsom konvektorer gennem en fremløbsledning, mens det afkølede vand fra varme-afgiverne gennem en returledning ledes tilbage til opvarmningsenheden, det være sig en kedel eller fjernvarme såvel direkte·eller via en varmeveksler. Oprindeligt har man anvendt stålrør til ledningsnettet, men på grund af problemer med tæring har man senere tillige anvendt kobberrør. På det seneste er der tilkommet plastrør, de såkaldte PEX-rør. Ved PEX-rørinstallationer føres der fra et centralt teknikskab separate rør i kontinuerte længder frem til de enkelte radiatorer eller konvektorer. I skabet samles rørene med tilslutningsrør på et manifold med ventiler, således at det er muligt at afspærre de forskellige rørstrenge. Pladsen bliver således hurtig trang i skabet.In traditional two-strand central heating systems, the heated water is passed to the individual heat generators such as convectors through a flow line, while the cooled water from the heat sources through a return line is fed back to the heating unit, be it a boiler or district heating, either directly or via a heat exchanger. Initially, steel pipes have been used for the wiring grid, but due to corrosion problems later copper pipes have also been used. Recently, plastic pipes, the so-called PEX pipes, have been added. In PEX pipe installations, separate pipes of continuous length are fed from the central engineering cabinet to the individual radiators or convectors. In the cabinet, the pipes with connecting pipes are assembled on a manifold with valves, so that the various pipe strings can be blocked. The space thus becomes quickly cramped in the closet.

Et alternativ til denne løsning med et teknikskab er at fastgøre en tilslutningsdåse på eller i væggen, som angivet i dansk brugsmodel DK 95 00128 U3. Her tilsluttes en konvektor-enhed til et udtag i tilslutningsdåsen, som tillige har to andre tilslutninger for tilslutning til rørnettets fremløbs--og returledning. Ved hver af konvektorenhedernes ender er der monteret en tilslutningsdåse, og fra dåserne føres rørledningerne videre til næste konvektor under gulvet, i paneler eller i væggen. Denne måde at udføre et centralvarmesystem på har sine fordele i, at når konvektorernes placering er fastlagt kan dåserne anbringes og ledningsnettet laves færdig og trykprøves. Konvektorenhederne inklusiv reguleringsenhed monteres derefter, idet de blot skal tilsluttes systemet via dåserne. Gulvet kan således føres ubrudt under konvektorenhederne. Fordelen er desuden at der ikke er nogle skjulte rørsamlinger i forbindelse med systemet.An alternative to this solution with a technique cabinet is to attach a socket on or in the wall, as specified in Danish utility model DK 95 00128 U3. Here, a convector unit is connected to an outlet in the connection box, which also has two other connections for connection to the pipeline supply and return line. At each end of the convector units a connection box is mounted, and from the cans the pipelines are passed to the next convector under the floor, in panels or in the wall. This way of conducting a central heating system has its advantages in that when the location of the convectors is determined, the cans can be placed and the wiring harness made ready and pressure tested. The convector units including control unit are then mounted, simply connecting to the system via the cans. The floor can thus be passed uninterruptedly under the convector units. The advantage is also that there are no hidden pipe joints in connection with the system.

Ved et centralvarmeanlæg ifølge DK 95 00128 U3 er der imidlertid den ulempe, at ved varmeafgiverenheder, som ikke er forberedt med en reguleringsanordning, såsom det er til- 2 DK 97 00137 U3 fældet ved gulwarmeelementer, ikke vil kunne reguleres, da hele rørføringen ligger skjult under gulvet eller i væggen.However, in a central heating system according to DK 95 00128 U3 there is the disadvantage that for heat dispensing units which are not prepared with a control device, such as is provided by underfloor heating elements, it will not be possible to regulate as the entire piping is hidden under the floor or in the wall.

Den kendte type tilslutningsdåse er således begrænset til brug i forbindelse med varmeafgivere f.eks. radiatorer, som er beregnet for montage med reguleringsanordninger, såsom simple ventilreguleringsenheder eller termostatventiler.Thus, the known type of junction box is limited to use in connection with heat emitters, e.g. radiators designed for mounting with controls such as simple valve control units or thermostat valves.

Det er ved opfindelsen indset, at en tilslutningsenhed af den art, hvor der mellem to systemtilslutninger er anbragt et konvektorudtag for gulvvarmeelementer, kan udbygges med en reguleringsventil i forbindelse med konvektorudtaget til en gulwarmeafgiverenhed, således at tilførslen af opvarmet vand til den gulwarmeafgiverenhed, der er monteret i centralvarmeanlæg, kan reguleres, uanset om enheden forud er indrettet for montage af reguleringsenheder, såsom termostatventiler, eller ikke.It is understood by the invention that a connection unit of the kind in which a convector outlet for underfloor heating elements can be arranged between two system connections can be extended with a control valve in connection with the convector outlet to a underfloor heating unit, so that the supply of heated water to the underfloor heating unit is provided. mounted in central heating systems, can be controlled whether or not the unit is pre-arranged for mounting of control units, such as thermostat valves.

Denne reguleringsventil i en tilslutningsenhed ifølge opfindelsen kan være udført som en termostatreguleret ventil i forbindelse med et konvektorudtag for en gulwarmeafgiverenhed. Fordelene herved er især, at man ved anvendelse af reguleringsventilen ifølge opfindelsen ikke be'høver at etablere et manifold med reguleringsventiler for gulwarmeafgiverne, samt omfattende returrørføringer fra gulwarmeafgiverne tilbage til nævnte manifold, idet reguleringen af varmetilførslen til gulwarmeafgiverelementerne kan foretages i samme rum som denne er placeret, eventuelt ved hjælp af en termostatventil.This control valve in a connection unit according to the invention may be designed as a thermostatically controlled valve in connection with a convector outlet for a floor heating unit. The advantages of this are in particular that, using the control valve according to the invention, it is not necessary to establish a manifold with control valves for the floor heating emitters, as well as extensive return pipes from the floor heating emitters back to said manifold, since the regulation of the heat supply to the floor heating elements can be made in the same room. positioned, possibly by means of a thermostat valve.

I en anden udførelse af reguleringsventilen kan denne være udført som en motordrevet centralstyret ventil. Disse udførelsesformer kan være hensigtsmæssige, såfremt der i et centralvarmeanlæg ønskes f.eks. tidstyring af varmen i de enkelte rum.In another embodiment of the control valve, this can be designed as a motor driven central controlled valve. These embodiments may be convenient if, for example, a central heating system is desired. time management of the heat in the individual rooms.

I en foretrukken udførelsesform er tilslutningsenheden ifølge opfindelsen udført med en rørforgrener i form af et krydsstykke med de to udtag for systemtilslutninger fortrinsvis symmetrisk beliggende omkring konvektorudtaget og en ventilreceptor. De to udtag for systemtilslutning kan fordelagtigvis være udført med vinklede rørstykker, som er monteret i krydsstykket. Herved kan rørføringerne føres frem til til- 3 DK 97 00137 U3 slutningsenheden fra forskellige retninger. Reguleringsventilen kan være arrangeret i forbindelse med denne symmetriakse i krydsstykket ud for konvektorudtaget for en gulvvarme-afgiverenhed. Tilslutningsenheden kan fastgøres til en bagplade og indkapsles i en let aftagelig beskyttelseskappe, som samvirker med bagpladen, hvorved rørsamlingerne i tilslutningsenheden er beskyttede. Enheden fremstår således i fær-digmonteret tilstand som en tilslutningsdåse, der kan monteres i eller ved en fodliste, og placeringen af tilslutningsdåsen kan fremstå mere diskret. Et drejeligt betjeningshåndtag, som står i forbindelse med reguleringsventilen, kan arrangeres udenfor denne kappe.In a preferred embodiment, the connection unit according to the invention is designed with a pipe branch in the form of a crosspiece having the two system connection outlets preferably symmetrically located around the convector outlet and a valve receptor. Advantageously, the two system connection outlets may be provided with angled pipe pieces mounted in the junction. In this way, the piping can be advanced to the connecting unit from different directions. The control valve may be arranged in connection with this axis of symmetry in the junction next to the convector outlet for a underfloor heating unit. The connection unit can be attached to a backplate and encased in an easily removable protective sheath which cooperates with the backplate, thereby protecting the pipe joints in the connection unit. Thus, the unit appears in pre-assembled condition as a junction box which can be mounted in or by a footboard, and the location of the junction box may appear more discreet. A swivel control lever connected to the control valve can be arranged outside this casing.

En yderligere fordel ved en tilslutningsdåse ifølge opfindelsen er, at centralvarmeanlægget kan trykprøves forud for lægning af gulvet og færdiggørelse af væggene.A further advantage of a junction box according to the invention is that the central heating system can be pressure tested prior to laying the floor and finishing the walls.

Opfindelsen er i det følgende nærmere beskrevet med henvisning til tegningen, på hvilken fig. 1 er et principdiagram over et traditionelt centralvarmeanlæg med radiatorer og gulvvarme, fig. 2 et principdiagram over et centralvarmeanlæg med radiatorer og gulvvarme med tilslutningsenheden ifølge opfindelsen, fig. 3 viser en eksploderet tegning i perspektiv af en foretrukken udførelse af en tilslutningsdåse ifølge opfindelsen, og fig. 4 et snitbillede af denne.The invention is described in more detail below with reference to the drawing, in which: FIG. 1 is a principle diagram of a traditional central heating system with radiators and underfloor heating; FIG. 2 is a diagram of a central heating system with radiators and underfloor heating with the connection unit according to the invention; FIG. 3 is an exploded perspective view of a preferred embodiment of a socket according to the invention; and FIG. 4 is a sectional view of this one.

I fig.-l er vist et principdiagram over et traditionelt centralvarmeanlæg med radiatorer 30 og gulwarmeafgiverele-menter 32, med en fremløbsledning 34 og en returledning 36, tilsluttet en kedel 31. Radiatorerne 30 er tilsluttet systemets fremløbs- og returledning 34, 36 ved hjælp af tilslutningsdåser 38 som angivet i dansk brugsmodel DK 95 00128 U3. Som det fremgår af diagrammet er gulwarmeafgiverelementerne 32 tilsluttet anlægget ved et manifold 40 med reguleringsventiler 42, i det viste udførelseseksempel termostatventiler, på en afgrening på fremløbsledningen 34. Returløbet fra gulv-varmeafgiverelementerne 32 er tilsluttet returledningen 36 ved et afgrening. Varmeafgivelsen fra gulvvarmeelementerne 32 4 DK 97 00137 U3 kan være styret af termostater med følere 44 anbragt i de rum hvori der er gulvvarme. Dette kræver dog at der trækkes forbindelser 46 mellem termostatventilerne følerne, som antydet på diagrammet i fig. 1. Alt i alt vil det således ved den 5 traditionelle opbygningsmåde for centralvarmeanlæg være nødvendigt at etablere det særlige manifold for tilslutning af gulvvarmeelementer, med deraf følgende omfattende returrørføringer til returledningen 36. Desuden vil det ved termostatstyring af varmeafgivelsen være nødvendigt at etablere de 10 særlige forbindelser 46 mellem rumfølere 44 og termostaterne.Fig. 1 shows a principle diagram of a traditional central heating system with radiators 30 and underfloor heating elements 32, with a flow line 34 and a return line 36, connected to a boiler 31. The radiators 30 are connected to the system supply and return line 34, 36 by means of of junction boxes 38 as specified in Danish utility model DK 95 00128 U3. As can be seen in the diagram, the floor heat exchanger elements 32 are connected to the system by a manifold 40 with control valves 42, in the illustrated embodiment thermostat valves, on a branch on the supply line 34. The return flow from the floor heat-supply elements 32 is connected to the return line 36 at a branch. The heat output from the underfloor heating elements 32 4 DK 97 00137 U3 may be controlled by thermostats with sensors 44 located in the rooms in which there is underfloor heating. However, this requires that connections 46 be drawn between the thermostat valves sensors, as indicated on the diagram in FIG. 1. All in all, it will thus be necessary to establish the special manifold for connection of underfloor heating elements in the 5 traditional design method for central heating systems, with consequent extensive return pipes to the return line 36. In addition, the thermostatic control of the heat release will need to establish the 10 special connections 46 between room sensors 44 and the thermostats.

I fig. 2 er vist et principdiagram over et centralvarmeanlæg med radiatorer og gulwarme med tilslutningsenheden 47 ifølge opfindelsen. Som det fremgår af diagrammet er der til det to-strengede system tilsluttet radiatorer 30 og for overis skuelighedens skyld blot et enkelt gulwarmeafgiverelement 32, med en fremløbsledning 34 og en returledning 36. Radiatorerne 30 er tilsluttet systemets fremløbs- og returledning 34, 36 ved hjælp af tilslutningsdåser 38 som angivet i dansk brugsmodel DK 95 00128 U3. Gulwarmeafgiverelementet 32 er i 20 · dette tilfælde direkte tilsluttet fremløbsledningen 34 ved hjælp af en særlig tilslutningsdåse 48 med nedadrettet udtag, beregnet for tilslutning af et gulwarme lement 32. Gulwarme-elementet 32 er i det viste udførelseseksempel tilsluttet direkte på returledningen 36 ved hjælp af en tilslutningsenhed 25 47 ifølge opfindelsen, der er forsynet med termostatstyret reguleringsventil. Som det fremgår ved sammenligning af principdi ag rammerne i fig. 1 og 2, åbner anvendelsen af tilslutningsenheden 47 ifølge opfindelsen mulighed for en betydelig mere enkel og simpel rørføring for tilslutning af gulwarme-30 elementer. Eksempelvis spares de lange returledninger for gulvvarmeelementerne 32, manifold 40, samt etablering af rumfølere med tilhørende forbindelser til rummene med gulwarme; hertil kommer yderligere at der spares skabsplads eller rum for etablering af nævnte manifold 40.In FIG. 2 is a principle diagram of a central heating system with radiators and underfloor heating with the connection unit 47 according to the invention. As can be seen from the diagram, radiators 30 are connected to the two-string system and, for the sake of simplicity, only a single floor heating element 32, with a supply line 34 and a return line 36. The radiators 30 are connected to the system supply and return line 34, 36 by means of of junction boxes 38 as specified in Danish utility model DK 95 00128 U3. The floor heating element 32 is 20, in this case, directly connected to the supply line 34 by means of a special downward socket 48, intended for connection of a floor heating element 32. The floor heating element 32 is connected directly to the return line 36 in the illustrated example. connection unit 25 47 according to the invention, provided with thermostatically controlled control valve. As can be seen by comparing the principle diagrams in FIG. 1 and 2, the use of connection unit 47 according to the invention allows for a much more simple and simple piping for connection of underfloor heating elements. For example, the long return lines for the floor heating elements 32, manifold 40, and the establishment of room sensors with associated connections to the rooms with floor heating are saved; In addition, there is also a saving space or space for establishing the manifold 40.

35 I fig. 3 er vist en tilslutningsenhed 47 ifølge opfindel sen bestående af en rørforgrener i form af et krydsstykke 2 med to vinkelstykker 6, som er monteret i to overfor hinanden liggende ender i krydsstykket 2. Via disse vinkelstykker 6 5 DK 97 00137 U3 tilsluttes tilslutningsenheden centralvarmeanlæggets rørføringer. Et konvektorudtag 4 er placeret i krydsstykket 2 mellem disse to systemtilslutninger 6. Krydsstykket 2 er skruet fast til en bagplade 10, som kan sømmes, skrues eller på anden måde fastgøres til en væg eller en fodliste. En beskyttelseskappe 8 fastsættes på bagpladen 10, således at tilslutningsenheden 2,4, 6 afdækkes. Kappen 8 kan være forsynet med to skinneflige, således at kappen 8 monteres, ved at den forskydes ned over bagpladen 10 med fligene bagved denne. Af andre fastgørelsesmetoder kan nævnes, at kappen 8 kan "klikkes" på, eller at fligene er udformet som gribeflige, som modsvarer udskæringer i pladen for indgreb mellem kappen og pladen.35 In FIG. 3, a connection unit 47 according to the invention is shown consisting of a pipe branch in the form of a crosspiece 2 with two angles 6, which are mounted at two opposite ends of the crosspiece 2. Via these angles 6, the connection unit is connected to the pipes of the central heating system. . A convector outlet 4 is located in the crosspiece 2 between these two system connections 6. The crosspiece 2 is screwed to a backplate 10 which can be seamed, screwed or otherwise fastened to a wall or footboard. A protective cap 8 is secured to the back plate 10 so that the connection unit 2,4,6 is covered. The sheath 8 may be provided with two rail tabs so that the sheath 8 is mounted by sliding it down over the backplate 10 with the tabs behind it. Other attachment methods may be mentioned that the sheath 8 can be "clicked on" or that the tabs are designed as gripping tabs, which correspond to cuts in the plate for engagement between the sheath and the plate.

Den indad vendende ende i konvektorudtaget 4 er forsynet med et ventilsæde 12, som samvirker med en anlægflade 22 på en ventilenhed 14, som indsættes i krydsstykket 2 overfor udtaget 4. I denne ventilenhed 14 er en ventilstang 20 fjedrende monteret. Førnævnte anlægsflade 22 er monteret i den ende af stangen 20, som rager ind i krydsstykket 2. Ventilstangen 20 kan forskydes i ventilenheden 14 ved at dreje betjeningshåndtaget 18, som via et mellemstykke 16 samvirker med ventilstangen 20.The inwardly facing end of the convector outlet 4 is provided with a valve seat 12 which cooperates with a contact surface 22 of a valve unit 14 which is inserted into the crosspiece 2 opposite the outlet 4. In this valve unit 14 a valve rod 20 is resiliently mounted. The aforementioned abutment surface 22 is mounted at the end of the rod 20 which projects into the crosspiece 2. The valve rod 20 can be displaced in the valve unit 14 by turning the operating handle 18, which interacts with the valve rod 20 via an intermediate piece 16.

Reguleringsventilen 14, 16, 18, 20, 22 monteres efter, at kappen 8 er fastsat på bagpladen 10 gennem en åbning i kappen 8, som efter montage modsvarer positionen af den øvre ende af krydsstykket 2, hvor ventilanordningen skal isættes.The control valve 14, 16, 18, 20, 22 is mounted after the sheath 8 is fixed to the backplate 10 through an opening in the sheath 8 which, after mounting, corresponds to the position of the upper end of the crosspiece 2 where the valve device is to be inserted.
