Description
Oppfinnelsen angår et apparat for romoppvarming og mad. et rør-system .anordnet i ett ell-ér flere hovedsakelig parallelle vertikale.'plan for gjennomstrømning av et'• varmeavgivende medium, f.eks.<;>>.vånn, fra et innløp til et utløp, idet rørsystemet omfatter minst^to-. adskilte rørsløyfer i god varmeledende kontakt med sekundærelementer og anordnet, på forskjellig høydenivå mellom et vertikalt tilløpsrør, som- kommuniserer med innløpet og et samle- The invention relates to a device for space heating and food. a pipe system arranged in one or more essentially parallel vertical planes for the flow of a heat-emitting medium, e.g. water, from an inlet to an outlet, the pipe system comprising at least two-. separate pipe loops in good heat-conducting contact with secondary elements and arranged, at different height levels, between a vertical inlet pipe, which communicates with the inlet and a collecting
rør parallelt med tilløpsrøret og forbundet med utløpet. pipe parallel to the inlet pipe and connected to the outlet.
Kjente varmeapparater av-denne art anvendes vanligvis i sentral-varmesystemer for oppvarming av rom i bygninger. Herunder er det-ønskelig at den varme som avgis fra rørsystemet fordeles så jevntr.som mulig over-en viss flate, som f.eks. en frontpiate eller lignende, således at det oppnås én behagelig oppvarmingseffekt og kald .trekk ved vinduer unngås. Videre' bør sådanne apparater for romoppvarming være så ufølsomme som mulig for luft som har trengt inn- i -systemet, således av vannsirkulasj-onen og varmeavgivelsen kan opprettholdes og vannet ikke fryser til is, hvis rommet nedkjøles, hvilket ellers kan føre til skader på ventiler og lignende,' samt vannskader når isen tiner.'' Dessuten bør konstruk-sjonen .være slik at" tilvirkningen blir enkel og billig samt flere forskjellige størrelser og modeller kan fremstilles på rasjonell måte... Known heaters of this kind are usually used in central heating systems for heating rooms in buildings. Here, it is desirable that the heat emitted from the pipe system is distributed as evenly as possible over a certain surface, such as e.g. a front piate or similar, so that a pleasant heating effect is achieved and cold drafts at windows are avoided. Furthermore, such devices for space heating should be as insensitive as possible to air that has penetrated into the system, so that the water circulation and heat output can be maintained and the water does not freeze to ice if the room cools down, which could otherwise lead to damage to valves and the like,' as well as water damage when the ice melts.'' Furthermore, the construction should be such that "the manufacture is simple and cheap and several different sizes and models can be manufactured in a rational way...
.Hittil''.- k-jente apparater for .romoppvarming- tii svarer imidlertid ikke-de-;'-ovenf or angitte fordringer. Ved ;en kjent type er f. eks.. rørsløyféne trukket méllom, et horisontalt, tilløpsrør og et sanilerør-''anordnet horisontalt under tilløpsrøret, hvilket medfører Until now, devices for space heating do not, however, meet the requirements stated above. In a known type, for example, the pipe loops are drawn between a horizontal inflow pipe and a sanitary pipe arranged horizontally below the inflow pipe, which results in
'at. selv en relati.v liten luftmengde som har trengt inn"' i" '.systemet, kan forstyrre eller, til og med helt stoppe vannsirkulasjonen. 'that. even a relatively small amount of air that has penetrated the system can disrupt or even completely stop the water circulation.
For at' varmeapparatet atter skal fungere, må derfor iden.innestengte luftmengde slippes: ut ved hjelp av en utluftningsanordning, som vanligvis manøvreres manuelt.. In order for the heater to function again, the trapped air volume must therefore be released by means of a venting device, which is usually operated manually.
Formålet ved foreliggende oppfinnelse er således a fremskaffe et varmeapparat av innledningsvis angitt art, og som muliggjør en jevn og behagelig . yarmeavgivelse samt fungerer tilfredsstillende selv med en forholdsvis stor innesluttet luftmengde, bg i tillegg tross enkel oppbygning og lave fremstillingsomkostnirigér muliggjør flere variasjoner med hensyn til varmekapasitet, omfang, og ytre utformning. Dette oppnås ved de prinsipielle særtrekk som er angitt.i den karakteriserende del av det etterfølgende-'.patentkrav 1 The purpose of the present invention is thus to provide a heater of the kind indicated at the outset, which enables a smooth and comfortable . heat output and works satisfactorily even with a relatively large enclosed amount of air, bg in addition, despite the simple structure and low manufacturing costs, it enables several variations with regard to heat capacity, scope and external design. This is achieved by the principal features which are stated in the characterizing part of the following patent claim 1
•Oppfinnelsen vil' imidlertid nå bli nærmere beskrevet under henvisning til de'vedføyde tegninger, hvorpå: 'iV However, the invention will now be described in more detail with reference to the attached drawings, whereupon:

Rørsystemet er videre utstyrt med et vertikalt tilløpsrør-8 som kommuniserer med innløpet-7, idet tilløpsrøret oventil er forsynt, med en utluf tningsanor.dning 13 og med fire tilsluttede rørsløyfer 2, 2', som er anordnet på to •forskjellige nivåer i to parallelle vertikalplan, og som hver for Fig. 1 shows a.. perspective sketch of an apparatus for space heating according to the invention; Fig. 2 shows part of the apparatus seen from above; ,<: >Fig. 3 shows one embodiment of an inlet pipe on a larger scale, and Fig. 4 and 5 show two further examples of the design of the pipe system. The embodiment of the heater shown in fig. 1 and 2, are equipped with 'a pipe system for the flow through' of a heat-emitting medium, v which, e.g. water, from an inlet 7, which is provided ■with a shut-off or regulating valve, to an outlet'. 11 which. is located near the inlet. The pipe system is further equipped with a vertical inlet pipe-8 which communicates with the inlet-7, the inlet pipe being provided at the top with a venting device 13 and with four connected pipe loops 2, 2', which are arranged at two different levels in two parallel vertical planes, and which each for
seg- leder til-ék felles vertikalt samlerør 10, som i sin tur kommuniserer med utløpet 11. Sekundærelementer 3, 3', i form av foldete plater er anbragt i g,od varmeledende kontakt med rør-sløyfene 2, 2- . Vid'ere er apparatet 1 utstyrt med en frontplate, 4 vendt mot rommet.og som kan .være oppdelt i seksjoner, en bakre dekkplate 5, samt endestykker og ikke viste opphengningsorganer for radiatorens opphengning på en vegg. Rørsløyfene 2, 2' samt leads to a common vertical collecting pipe 10, which in turn communicates with the outlet 11. Secondary elements 3, 3', in the form of folded plates, are placed in good heat-conducting contact with the pipe loops 2, 2-. Furthermore, the device 1 is equipped with a front plate, 4 facing the room and which can be divided into sections, a rear cover plate 5, as well as end pieces and not shown suspension means for hanging the radiator on a wall. The pipe loops 2, 2' as well
de fremre og bakre plater 4, .5 er fiksert i forhold til hverandre ved hjelp av vertikale tverrstilte støtteplater 6, 6'. the front and rear plates 4, 5 are fixed in relation to each other by means of vertical transverse support plates 6, 6'.
,I fig. 4 og 5 er det vist to forskjellige utførelsesformer av : de separate rørsløyfer 2.. I fig. 4 er sløyfene likesom i fig. 1.,'-'.' , in fig. 4 and 5 show two different embodiments of: the separate pipe loops 2.. In fig. 4, the loops are the same as in fig. 1.,'-'.'

Det vesentlige i henhold til oppfinnelsen er at rørsløyfene 2 er The essential thing according to the invention is that the pipe loops 2 are
.innkoblet på forskjellige nivåer mellom det vertikale tilløpsrør .connected at different levels between the vertical inlet pipe
■ og ,det vertikale samlerør 10. •.'•Dette arrangement gjør det mulig ■ and ,the vertical header 10. •.'•This arrangement makes it possible
•at-det vann .som tilføres gjennom innløpet 7 under trykk, tilføres tilløpsrøret 8,.og fordeles gjennom sløyfene 2, samt ledes ut gjennom samlerøret .10 og utløpet 11.' Ved innløpsenden for hver sløyfe har vannet omtrent like høy temperatur, således at sekundærelementéne 3 i de forskjellige nivåer hovedsakelig mottar like stor varmétilføresel fra.rørsystemet og frontplaten 4 blir jevnt oppvarmet. Hvis' luft trenger inn i rørsystemet vil den ■ •] samle seg oventil i dette. Derved forstyrres sirkulasjonen i den eller de øyre- sløyfer, mens, yannstrømningen opprettholdes i, .'.V den nederste sløyfe helt til hele den.del av rørsystemet som ligger ovenfor, denne sløyfe, er fylt med luft. Varmeapparatet eller radiatoren kan således fungere tilfredsstillende'selv med forholdsvis stor. innesluttet luftmengde, og det foreligger neppe noen risiko-f or frostskader så''lenge innløpsventilen er åpen og "f ■vannets drivtr-ykk holdes ti Ls:trekk elig høyt. '■:.€' ■For at strømningsfordel ingen mellom de ferskjelligé rsrsløyfer skal holdes jevn, har det vist seg fordelaktig å utforme ti11«ps-, røret på en spesiell måte. Hvis f.eks. rørsløyfene. er. meget korte og deres strømningsmotstand er lav, kan forskjellen i statisk trykk på de forskjellige nivåer medføre at strømningen gjennom den nederste sløyfe' blir betraktelig større enn gjennom den- øverste sløyfe. Denne "effekt blir naturligvis mer markert'jo større utstrekning varmeapparatet har i høyderetningen og.jo mindre utstrekning det har. i siderétningen. • that the water supplied through the inlet 7 under pressure is supplied to the inlet pipe 8 and distributed through the loops 2, as well as led out through the collection pipe 10 and the outlet 11. At the inlet end of each loop, the water has approximately the same temperature, so that the secondary elements 3 in the different levels mainly receive the same amount of heat supply from the pipe system and the front plate 4 is heated evenly. If air penetrates into the pipe system, it will ■ •] collect at the top of this. Thereby, the circulation in the eye loop(s) is disrupted, while the air flow is maintained in the lowermost loop until the entire part of the pipe system above, this loop, is filled with air. The heater or radiator can thus function satisfactorily even with a relatively large trapped amount of air, and there is hardly any risk of frost damage as long as the inlet valve is open and the water pressure is kept as high as possible. ■In order for the flow advantage between the different rsrs loops to be kept uniform, it has proved advantageous to design the ti11«ps pipe in a special way. If e.g. the pipe loops. is. very short and their flow resistance is low, the difference in static pressure at the different levels can cause the flow through the lower loop to be considerably greater than through the upper loop. This "effect naturally becomes more marked the greater the extent the heater has in the vertical direction and the smaller the extent it has in the lateral direction.
I henhold til oppfinnelsen er tilløpsrøret 8, som vist i fig. 3, utstyrt med en .ytre mantel i form av et ytterrør 12 med. en utluftningsanordning 13 ved sin øvre ende. Ytterrøret er på tre' forskjellige nivåer utstyrt med.tilslutningsåpninger 14 for de respektive rørsløyfer 2. Et rør i forbindelse' med innløpet 7 er trukket gjennom ytterrørets nedre ende og danner innvendig i tilløpsrøret 8'et innerrør 15 som er konsentrisk med ytterrøret og strekker seg forbi ytterrørets tilslutningsåpninger samt er åpent i sin øvre -endé. I området for tilslutningsåpningene 14 er According to the invention, the inlet pipe 8, as shown in fig. 3, equipped with an outer jacket in the form of an outer tube 12 with. a venting device 13 at its upper end. The outer pipe is equipped at three different levels with connection openings 14 for the respective pipe loops 2. A pipe in connection with the inlet 7 is drawn through the lower end of the outer pipe and forms inside the inlet pipe 8 an inner pipe 15 which is concentric with the outer pipe and extends past the outer pipe's connection openings and is open at its upper end. In the area of the connection openings 14 is
innerrøret forsynt-med et antall hull eller sideåpninger 16 som er. små sammenlignet med innerrarets strømningstverrsnitt, således at en del av det vann som tilføres fra innløpet 7, kan trenge ut i ytterrøret 12 gjennom disse åpninger. Så lenge systemet er fullstendig fylt^med vann, vil dette delvis strømme ut fra den øvré ende av innerrøret 15, og delvis gjennom sideåpningene 16, hvorved det kan oppnås: en 1ikeartet fordeling av vannstrømningen mellom de forskjellige tilslutningsåpninger 14. I visse tilfeller kan det the inner tube is provided with a number of holes or side openings 16 which are small compared to the flow cross-section of the inner tube, so that part of the water supplied from the inlet 7 can penetrate into the outer tube 12 through these openings. As long as the system is completely filled with water, this will partly flow out from the upper end of the inner pipe 15, and partly through the side openings 16, whereby it can be achieved: a uniform distribution of the water flow between the different connection openings 14. In certain cases, it can
være fordelaktig å gi tilslutningsåpningene 14 forskjellig strømningstverrsnitt på forskjellige nivåer for å oppnå ønsket strømningsfordeling. be advantageous to give the connection openings 14 different flow cross-sections at different levels in order to achieve the desired flow distribution.
■ Ved hjelp av den utførelse av tilløpsrøret 8 som er vist i fig. 3, kan det således oppnås en jevn vannstrømningsfordeling i sløyfene ■ By means of the design of the inlet pipe 8 shown in fig. 3, a uniform water flow distribution in the loops can thus be achieved
på forskjellige nivåer, selv i høye og smale radiatorer.. Sideåpningene 16 i innerrøret 15 sikrer herunder at sirkulasjonen opprettholdes selv om det er'innesluttet luft i rørsystemets øvre partier. at different levels, even in tall and narrow radiators.. The side openings 16 in the inner tube 15 ensure that circulation is maintained even if there is trapped air in the upper parts of the pipe system.
Det bør bemerkes at varmeapparatet i henhold til oppfinnelsen har It should be noted that the heater according to the invention has
store tilvirkningstekniske fordeler. Tilvirkningen kan baseres på en- grunnenhet som består av- et komplett rørsystem med separate rørsløyfer i samme vertikalplan som tilløpsrøret og samlerøret. Til denne grunnenhet kan det tilføres ytterligere rørsløyfer i major manufacturing advantages. The production can be based on a basic unit consisting of a complete pipe system with separate pipe loops in the same vertical plane as the inlet pipe and the collecting pipe. Additional pipe loops can be added to this basic unit
ett eller flere plan og forbundet mellom tilløpsrøret og samlerøret' parallelt med de opprinnelige rørsløyfer (se fig. 1 og 2). Herved, one or more planes and connected between the inlet pipe and the collection pipe' parallel to the original pipe loops (see fig. 1 and 2). Hereby,
kan grunnenheten på enkel måte modifiseres slik at apparatets , 'varmekapasitet blir vesentlig,høyere, tross bibeholdte ytter- :„-,-.dimensjoner i høyde- og side-retningen. Også lagerholdningen lettes, da bare grunnenheter med varierende antall rørsløyfer og lengde samt separate rørsløyfer av varierende lengde behøver å,■ finnes.på lager. Ved denne! enkle tilslutning kan selv apparater -.-' the basic unit can be easily modified so that the appliance's heating capacity is significantly higher, despite the retained external dimensions in the height and side directions. Inventory is also made easier, as only basic units with varying numbers of pipe loops and lengths as well as separate pipe loops of varying lengths need to be kept in stock. By this one! simple connection can even appliances -.-'
med rørsløyfer i to eller flere parallelle plan omgående gjøres ■ • -.. leveranseklare, etter kundens. ønske. with pipe loops in two or more parallel planes are immediately made ■ • -.. ready for delivery, according to the customer's. desire.
