Description
Oppfinnelsen angår en takkonstruksjon som er en videreføring av et kjent prinsipp (det såkalte motstrømstak) hvor luft tas utenfra og inn i rommet mellom et luftett yttertak og en varmeisolerende og luftgjennomtrengelig himling. The invention relates to a roof structure which is a continuation of a known principle (the so-called counter-flow roof) where air is taken from outside into the space between an airtight outer roof and a heat-insulating and air-permeable ceiling.
Eksempel på et slikt system for å spare energi Example of such a system to save energy
er beskrevet i finsk utlegningsskrift nr. 55.404. is described in Finnish interpretation document no. 55.404.
Luften som vanligvis er forholdsvis kald og tørr, presses eller suges ned gjennom himlingen med ventilasjons-vifter eller lignende. Derved opptas i den gjennomstrømm-ende luften den varme og fukt som ellers ville ha strømmet ut fra det underliggende rommet med varmetap og kondens i takkonstruksjonen som følge. The air, which is usually relatively cold and dry, is forced or sucked down through the ceiling with ventilation fans or the like. Thereby, the heat and moisture that would otherwise have flowed out from the underlying room is taken up in the flowing air, resulting in heat loss and condensation in the roof structure.
Mangelen med denne konstruksjon er at den luft-gjennomtrengelige himlingen, som vanligvis består av mineral-ull, blir ødelagt ved brann, samt at mengden av den luft som kan passere himlingen, er begrenset av den temperatur som luften kan tillates å ha når den strømmer inn i nedenfor-liggende oppholdsrom. Himlingens lave varmekapasitet for-sterker dette problemet. Derfor kan ventilasjonsbehovet vanligvis ikke dekkes ved dette prinsippet. The disadvantage of this construction is that the air-permeable ceiling, which usually consists of mineral wool, is destroyed by fire, and that the amount of air that can pass through the ceiling is limited by the temperature that the air can be allowed to have when it flows into the living space below. The ceiling's low heat capacity reinforces this problem. Therefore, the ventilation requirement cannot usually be met by this principle.
Hensikten med oppfinnelsen er å unngå ovennevnte problemer, og dette tilveiebringes ved hjelp av et motstrøms-tak hvis karakteristiske trekk fremgår av krav 1. The purpose of the invention is to avoid the above-mentioned problems, and this is achieved by means of a counter-current roof whose characteristic features appear in claim 1.
Ytterligere trekk ved oppfinnelsen fremgår av underkravene. Further features of the invention appear from the subclaims.
Oppfinnelsen skal nå beskrives nærmere under hen-visning til tegningen, hvor The invention will now be described in more detail with reference to the drawing, where
fig. 1 viser et snitt gjennom en takkonstruksjon ifølge foreliggende oppfinnelse. Fig. 2 viser en ytterligere utførelsesform av konstruksjonen vist på fig. 1. Fig. 1 viser at en himling 3 bæres av en lastbærende og brannbeskyttende plate 4 som er luftgjennom-strømmelig. Dermed er konstruksjonen beskyttet mot brann og kan bære laster. fig. 1 shows a section through a roof structure according to the present invention. Fig. 2 shows a further embodiment of the construction shown in fig. 1. Fig. 1 shows that a ceiling 3 is supported by a load-bearing and fire-protective plate 4 which is permeable to air. Thus, the construction is protected against fire and can carry loads.
Den samme platen 4 har på grunn av sin betydelige vekt (som forøvrig tilpasses) en forholdsvis høy varmekapasitet som på grunn av luftgjennomstrømmingen fullt ut kan utnyttes til klimatisering av underliggende rom. En kan f.eks. om sommeren blåse kjølig natteluft gjennom platen som om dagen dermed blir i stand til å oppta varme fra solopp-hetet dagluft. The same plate 4 has, due to its considerable weight (which is also adaptable) a relatively high heat capacity which, due to the air flow, can be fully utilized for air conditioning the underlying room. One can e.g. in the summer, cool night air blows through the plate, which during the day is thus able to absorb heat from the sun-heated daytime air.
Taket vil også på grunn av sin moderate temperatur virke svalende ved at det absorberer varmestråling nedenfra. Betydelige energimengder, som ellers ville medgå i et aklimatiseringsanlegg, blir dermed innspart. Due to its moderate temperature, the roof will also have a cooling effect by absorbing heat radiation from below. Considerable amounts of energy, which would otherwise be included in an acclimatization system, are thus saved.
Fig. 2 viser samme prinsipp som vist på fig. 1, men i tillegg er lagt inn mellom isolasjon 3 og bærende plate 4 et luftgjennomstrømmelig varmeelement 5, f.eks. et elektrisk motstandsoppvarmet metallnett (hønsenetting eller lignende). Fig. 2 shows the same principle as shown in fig. 1, but in addition, an air-permeable heating element 5, e.g. an electrically resistance-heated metal grid (chicken wire or similar).
Med en slik oppvarmingsmulighet, kan en korrigere varmen på den gjennomstrømmende luften og dermed øke luft-mengden så meget at en i visse tilfelle ikke trenger ytterligere ventilasjon av underliggende rom. Dermed får man en rimelig løsning på oppvarmings- og ventilasjonsproblemet. With such a heating option, you can correct the heat of the air flowing through and thus increase the amount of air so much that, in certain cases, you do not need additional ventilation of the underlying room. This provides a reasonable solution to the heating and ventilation problem.
Den bærende og luftgjennomstrømmelige platen 4 (fig. 1 og 2) vil som følge av sin åpne struktur, virke lyddempende hvorved god akustikk oppnås tilnærmet som ved det kjente prinsipp beskrevet foran. The load-bearing and air-permeable plate 4 (fig. 1 and 2) will, as a result of its open structure, have a sound-absorbing effect, whereby good acoustics are achieved approximately as with the known principle described above.
