Description

Foreliggende oppfinnelse går ut på utnyttelse av markjord som befinner seg under bygningsanlegg, for lagring og/eller uttak av varmeenergi. . Det er kjent å utnytte jorden for uttak og eventuell lagring av varmeenergi ved å legge ned på grunne dybder i jorden, vesentlig horisontale ledninger for væsker, over et område som vanligvis er betydelig større enn den bygning som skal oppvarmes ved hjelp av den uttatte varme, som tas ut ved hjelp av i disse ledninger sirkulerende væske og tilføres en varmepumpe. Jordlaget med ledningene oppvarmes direkte av solenergi under varme perioder i året. Ved at et jordsjikt med enda grunnere dybder benyttes, er denne metoden begrenset når det gjelder lagring av store varmemengder. En annen ulempe ved denne kjente metoden er at anvendelsesmuligheten for andre formål av det av ledningene opptatte jordareal er sterkt begrenset. En ytterligere ulempe er at det av ledningene opptatte jordområdet på grunn av at ledningene er lagt ned forholdsvis grunt, ikke effektivt kan anvendes for lagring av varme som er tilført gjennom nevnte ledninger og som kommer f.eks. fra solfangere, ettersom den største delen av den der-ved tilførte varmeenergi i løpet av kort tid ville stråle ut og ledes bort av vinden fra nevnte område. The present invention relates to the utilization of topsoil located under buildings, for the storage and/or extraction of heat energy. . It is known to utilize the earth for extraction and possible storage of heat energy by laying down at shallow depths in the earth, essentially horizontal lines for liquids, over an area which is usually considerably larger than the building to be heated with the help of the extracted heat, which is taken out with the help of liquid circulating in these lines and supplied to a heat pump. The soil layer with the wires is heated directly by solar energy during hot periods of the year. As a soil layer with even shallower depths is used, this method is limited when it comes to storing large amounts of heat. Another disadvantage of this known method is that the possibility of using the land area occupied by the lines for other purposes is severely limited. A further disadvantage is that the ground area occupied by the lines, due to the fact that the lines are laid relatively shallow, cannot be effectively used for storing heat which is supplied through said lines and which comes e.g. from solar collectors, as the largest part of the heat energy thus supplied would radiate out and be carried away by the wind from the said area within a short time.

Hovedformålet med foreliggende oppfinnelse er at for lagring og uttak av varme, særlig billig langtemperaturvarme som fortrinnsvis kommer fra solfangere, å kunne utnytte jordlag under bygningsanlegg som hviler på fundamentpåler. The main purpose of the present invention is to be able to use soil layers under buildings that rest on foundation piles for the storage and extraction of heat, especially cheap long-temperature heat that preferably comes from solar collectors.

Dette oppnås ved at pålene utføres som rørprofiler av metall-materiale og at energi ved hjelp av minst én ledning som utgjør eller opptar en del av pålens tverrseksjon, føres til eller bortledes fra pålens innervegg under varmeveksling mellom denne og jorden som omgir pålen. This is achieved by the piles being made as pipe profiles of metal material and energy being led to or away from the pile's inner wall by means of at least one wire which constitutes or occupies part of the pile's cross-section during heat exchange between this and the soil surrounding the pile.

For formålet ifølge oppfinnelsen er god varmeoverføring mellom det i pålen nedførte mediet og den omgivende jorden av største betydning. For å oppnå dette utføres pålen hoved-sakelig helt av metall-materiale, f.eks. stål, som har meget, gode varmeledningsegenskaper sammenlignet med annet påle-materiale, f.eks. betong. Hvis pålen har rørprofil, kan man også utnytte dens indre rom direkte for ledning til eller fra av det varmebærende mediet, hvorved varmeoverføringen blir vesentlig lettere. Metallpåler kan dessuten utføres med mindre veggtykkelse enn påler av annet alminnelig materiale, som er fordelaktig, sett fra et varmeoverføringssynspunkt.. Iletallpåler kan vanligvis drives ned i jorden med lettere slag-redskap enn hva som er nødvendig for andre påler. Til slutt skal påpekes at metallpåler lett kan forsynes med profiler, f.eks. frlenser eller lignende, bl.a. gjennom påsveising. For the purposes of the invention, good heat transfer between the medium lowered into the pile and the surrounding soil is of the greatest importance. To achieve this, the pile is mainly made entirely of metal material, e.g. steel, which has very good heat conduction properties compared to other pile materials, e.g. concrete. If the pile has a tubular profile, its inner space can also be used directly for conduction to or from the heat-carrying medium, whereby heat transfer becomes significantly easier. Metal piles can also be made with a smaller wall thickness than piles made of other common materials, which is advantageous from a heat transfer point of view. Iletal piles can usually be driven into the ground with lighter impact tools than is necessary for other piles. Finally, it should be pointed out that metal piles can easily be supplied with profiles, e.g. frlenser or similar, i.a. through welding.

Andre fordeler og kjennetegn ved oppfinnelsen fremgår av nedenstående beskrivelse og vedlagte tegning over et utførelses-eksempel, samt patentkravene. Other advantages and characteristics of the invention can be seen from the description below and the attached drawing of an exemplary embodiment, as well as the patent claims.

På tegningen vises skjematisk en bygning 3 med underlig-gende jordlag 1 og 2, i hvilke rørformede påler 4 med tett vegg. er drevet ned. Pålene er ved sine øvre ender 5 forbundet med bygningens bunnflate 7, og deres nedre spiss 6 er tett for å forhindre inn- og utstrømning' av væske og flytende gass. Pålene er av stål og er rustbeskyttet gjennom anbringelse av et sjikt av seigt plastmateriale på yttersiden. Rørdiameteren kan være forskjellig, avhengig av omstendighetene, hensiktsmessig 50-200 mm, f.eks. ca. 75 mm. Pålene anbringes i et rutemønster på i og for seg kjent måte. De kan slås ned til fjellgrunnen, eller kan danne såkalte friksjonspåler. The drawing schematically shows a building 3 with underlying soil layers 1 and 2, in which tubular piles 4 with a dense wall. is driven down. The piles are connected at their upper ends 5 to the bottom surface 7 of the building, and their lower tip 6 is sealed to prevent the inflow and outflow of liquid and liquefied gas. The piles are made of steel and are protected from rust by placing a layer of tough plastic material on the outside. The pipe diameter can be different, depending on the circumstances, suitably 50-200 mm, e.g. about. 75 mm. The piles are placed in a grid pattern in a manner known per se. They can be driven down to the bedrock, or can form so-called friction piles.

I pålene er nedført et indre rør eller en slange 8 for gass eller væske, hvilket rør fra sin øvre ende 9, som er til-sluttet en sirkulasjonspumpe 11, strekker seg ned til i nærheten av pålens spiss 6, hvor rørets 8 ende 10 er åpen. Ved hjelp av røret 8 nedføres oppvarmet væske eller kald væske til pålens nedre ende, beroende på om pålen skal benyttes for varmelagring i eller varmeuttak fra de omgivende jordlag 1 og 2. An inner pipe or hose 8 for gas or liquid is lowered into the piles, which pipe from its upper end 9, which is connected to a circulation pump 11, extends down to near the tip 6 of the pile, where the end 10 of the pipe 8 is open. With the help of pipe 8, heated liquid or cold liquid is brought down to the lower end of the pile, depending on whether the pile is to be used for heat storage in or heat extraction from the surrounding soil layers 1 and 2.

Til venstre på figuren vises hvordan sirkulasjonspumpen er tilknyttet det varme væskeutløpet hos en solfanger 12 ved hjelp av en ledning 14, ved at solfangerens kalde væskeinnløp er tilknyttet den rørformede pålens 4 øvre ende 5 som for øvrig To the left of the figure is shown how the circulation pump is connected to the hot liquid outlet of a solar collector 12 by means of a line 14, in that the solar collector's cold liquid inlet is connected to the upper end 5 of the tubular pile 4 as otherwise

er tett. Så snart solfangerens væsketemperatur ved utløpet overstiger temperaturen i jordlagene 1 og 2, hvilket kan stad-festes ved at et organ som er innrettet for automatisk å styre drivmotoren for sirkulasjonspumpen, starter denne, og oppvarmet is tight. As soon as the solar collector's liquid temperature at the outlet exceeds the temperature in soil layers 1 and 2, which can be confirmed by the fact that a device which is arranged to automatically control the drive motor for the circulation pump starts this, and heated

omgivende jordlag 1 og 2. Denne varmelagring kan skje med døgn- eller sesongvariasjoner. Så snart temperaturen hos solfangerens varmeutløp har sunket under en forutbestemt verdi, ved hvilken varme ikke går over i jorden, stopper sirkulasjonspumpen automatisk. surrounding soil layers 1 and 2. This heat storage can occur with diurnal or seasonal variations. As soon as the temperature at the solar collector's heat outlet has fallen below a predetermined value, at which no heat is transferred to the earth, the circulation pump stops automatically.

I visse tilfeller kan det lønne seg ved hjelp av en varmepumpe å "løfte opp" væsketemperaturen innen den føres ned i pålen for- lagring av varmeenergien. Istedenfor solfangere kan annen billig varmekilde anvendes, f.eks. varmt spillvann eller lignende, og også billig natt-el-strøm, hvorved elektriske ledninger og oppvarmingselement anbringes i pålene. In certain cases, it can be worthwhile using a heat pump to "raise" the temperature of the liquid before it is led down into the pile for storage of the heat energy. Instead of solar collectors, another cheap heat source can be used, e.g. hot waste water or the like, and also cheap night-time electricity, whereby electric wires and heating elements are placed in the piles.

Røret 8 kan bestå av stål, og kan eventuelt være varme-isolerende, særskilt ved sitt øvre parti, for å motvirke varmeveksling mellom væsken i røret 8 og væsken i pålen 4. The pipe 8 may consist of steel, and may optionally be heat-insulating, particularly at its upper part, to counteract heat exchange between the liquid in the pipe 8 and the liquid in the pile 4.

Til høyre på figuren vises pålen og det indre røret 8 tilknyttet en varmepumpe 15 hvis varme side er tilknyttet en varmeradiator 16. Varmepumpen innbefatter en sirkulasjonspumpe for en væske, f.eks. en vann-glykol-blanding eller olje, som bringes til å strømme ned gjennom røret 8 og strømme tilbake gjennom pålen 4 under opptakelse av varme fra jorden 1 og 2 som omgir pålen. To the right of the figure, the pile and the inner pipe 8 are shown connected to a heat pump 15 whose hot side is connected to a heat radiator 16. The heat pump includes a circulation pump for a liquid, e.g. a water-glycol mixture or oil, which is made to flow down through the pipe 8 and flow back through the pile 4 while absorbing heat from the soil 1 and 2 surrounding the pile.

De påler ved hjelp av hvilke varme tas ut fra jorden kan være andre enn de påler ved hjelp av hvilke varme lagres i jorden, i hvilket tilfelle de førstnevnte pålene kan være fortrinnsvis jevnt fordelte mellom de sistnevnte pålene. Men det er også mulig å benytte samme påle for såvel varmelagring som varmeuttak, hvorved hensiktsmessige, f.eks. automatisk styrte ventiler finnes for omkobling av pålen 4 og dét indre røret 8 mellom en varmeleverende ledning, f.eks. en solfanger, og en varmeforbruker, f.eks. en varmepumpes kalde side. The piles by means of which heat is extracted from the earth may be different from the piles by means of which heat is stored in the earth, in which case the former piles may preferably be evenly distributed between the latter piles. But it is also possible to use the same pile for both heat storage and heat extraction, whereby appropriate, e.g. automatically controlled valves exist for switching the pile 4 and the inner pipe 8 between a heat-supplying line, e.g. a solar collector, and a heat consumer, e.g. a heat pump's cold side.

I visse tilfeller kan pålene utnyttes utelukkende for opptakelse av jordvarme som tilføres jordlagene 1 og 2 på annet vis enn ved hjelp av pålene, f.eks. gjennom grunnvann som er i bevegelse. In certain cases, the piles can be used exclusively for the absorption of ground heat that is supplied to soil layers 1 and 2 in a way other than with the help of the piles, e.g. through moving groundwater.

Ved lagring av varme ved hjelp av pålene som beskrevet, kan riktignok varmelekkasje oppstå. Den største delen derav går dog automatisk tilbake til bygningen 3 gjennom grunnflaten 7 og blir således nyttiggjort. Andre tap fra varmelageret kan When storing heat using the piles as described, it is true that heat leakage can occur. The largest part of this, however, automatically returns to the building 3 through the ground surface 7 and is thus utilized. Other losses from the heat storage can

minskes gjennom en jordisolering 20 rundt bygningen.is reduced through an earth insulation 20 around the building.

Ved å fylle pålens nedre, varmeoverførende del med et høyt-gjennomtrengelig materiale som danner en turbulent strømning av væsken, øker varmeutbyttet ved den omgivende jorden, da grensesjikt-strømning unngås på denne måten. By filling the lower, heat-transferring part of the pile with a highly permeable material that forms a turbulent flow of the liquid, the heat yield at the surrounding soil increases, as boundary layer flow is avoided in this way.

I de tilfeller hvor grunnvann strømmer inn i friksjons-jorden 2 og pålene skal anvendes for varmelagring, støpes den nedre delen av pålene igjen med betong 17 for å unngå borttransportering av varme gjennom det strømmende grunn-vannet. Pålen 4 kan være en skjøtepåle, f.eks. i og for seg kjente såkalte stål-plast-påler , sammenskjøtet ved hjelp av varme galvaniserte stålhylser som smeltes fast i skjøten til en momentstiv, strekkfast forbindelse. Lignende påler av ca. 75 mm stålrør kan ta last opp til ca. 14 tonn. In cases where ground water flows into the friction soil 2 and the piles are to be used for heat storage, the lower part of the piles is again cast with concrete 17 to avoid transport of heat away through the flowing ground water. The pile 4 can be a joint pile, e.g. in and of themselves known so-called steel-plastic piles, joined together using hot galvanized steel sleeves which are fused into the joint to form a moment-rigid, tensile-resistant connection. Similar piles of approx. 75 mm steel pipe can take loads of up to approx. 14 tons.

For å øke pålenes varmeoverføringskapasitet like overfor den omgivende jorden, kan de forsynes med langsgående stålflenser, eller også kan pålene forsynes med ikke-rundt, f.eks. kvadratisk, rektangulært, kryssformet eller stjerne-formet tverrsnitt. To increase the heat transfer capacity of the piles directly opposite the surrounding soil, they can be provided with longitudinal steel flanges, or the piles can be provided with non-round, e.g. square, rectangular, cross-shaped or star-shaped cross section.

Uttørkingseffekten hos jordmaterialet og dermed forringet varmeoverføring og varmelagring kan forhindres ved at dreneringsvann ledes frem til hver påle, slik som antydet ved 19. The drying effect of the soil material and thus impaired heat transfer and heat storage can be prevented by directing drainage water to each pile, as indicated at 19.

Pålenes lengde beror på grunnleggingsforholdene og The length of the piles depends on the foundation conditions and

bygningsanleggets størrelse. Vanligvis er pål-lengden ca. 5-10 m. the size of the building. Usually the pile length is approx. 5-10 m.

For å unngå korrosjon skjer væskesirkulasjonen gjennom pålen hensiktsmessig i et sluttet system. To avoid corrosion, liquid circulation through the pile takes place appropriately in a closed system.

Ved at varmelagringen .ifølge oppfinnelsen utnytter for bygningens grunnlegning allerede nødvendige eller hensiktsmessige påler for overføring av varme fra en billig varmekilde til jorden og uttak av varme fra denne, blir de utover dette nødvendige anleggsomkostningene for varmelagringen så lave at varmelagring av eksempelvis solenergi kan være et realistisk alternativ allerede til dagens prisforhold på energimarkedet. By the fact that the heat storage according to the invention utilizes piles already necessary or suitable for the building's foundation for transferring heat from a cheap heat source to the earth and extracting heat from it, the necessary installation costs for the heat storage are, in addition to this, so low that heat storage of, for example, solar energy can be a realistic alternative already to the current price conditions on the energy market.
