Description
15 20 25 30 35 8201314-5 2 en lokal. På sin uppåt vända gavelände har det en inlopps- öppning 1 för anslutning till en icke visad tilluftskanal. 15 20 25 30 35 8201314-5 2 and local. On its upwardly facing end end, it has an inlet opening 1 for connection to a supply air duct (not shown).
Mantelpartiet av donets hölje 5_har en halvcylindrisk frontdel 6 och tvâ plana sidodelar 7, av vilka den först- nämnda 6 är genombruten, för att bereda passage för till- luftsflödet från inloppsöppningen 1, medan de båda sido- delarna 7 är ogenombrutna. Front- och sidodelarnas an- gränsande kanter är knäckta utåt och sammansatta till en vertikalt förlöpande flänsfog 8 på vardera sidan av donet.The jacket portion of the housing 5 has a semi-cylindrical front part 6 and two flat side parts 7, of which the former 6 is pierced, to provide passage for the supply air flow from the inlet opening 1, while the two side parts 7 are unbroken. The adjacent edges of the front and side parts are bent outwards and assembled into a vertically extending flange joint 8 on each side of the device.
Höljet har även en undre gavel (fig. 2) som bildar donets botten och är ogenombruten.The housing also has a lower end (fig. 2) which forms the bottom of the device and is unbroken.
Ett i regel betydligt undertempererat tillufts- flöde tillföres donet och inloppsöppningen 1 och införes i lokalen med låg hastighet genom den genombrutna höljes- delen 6 för ästadkommande av en vistelsezon med ren och temperaturkontrollerad luft; Luftflödet tillföres därvid genom en luftgenomsläpplig fördelningsmatta 4, som är anordnad utmed den genombrutna delen 6 av höljets 5 mantel.A generally considerably sub-temperate supply air flow is supplied to the device and the inlet opening 1 and is introduced into the room at a low speed through the perforated housing part 6 to establish a living zone with clean and temperature-controlled air; The air flow is then supplied through an air-permeable distribution mat 4, which is arranged along the perforated part 6 of the casing 5 of the housing 5.
Fördelningsmattan 4 är utförd av flexibel skumplast med öppna celler och är belägen omedelbart innanför den genombrutna höljesdelen 6, vilken utgöres av en perforerad O plåt med en perforeringsgrad som erbjuder minst 65 6 fri area i sitt perforerade parti.The distribution mat 4 is made of flexible foam with open cells and is located immediately inside the perforated casing part 6, which consists of a perforated plate with a degree of perforation which offers at least 65 6 free area in its perforated portion.
På avstånd i djupled, inbördes och från mattan H, är två perforerade strypplâtar 2 och 3 anordnade innanför mattan 4. Strypplätarna är belägna den ena 2 innanför den andra 3 och så anslutna till höljet 5 att hela luftflödet måste passera igenom först plåtens 2 och sedan plâtens 3 perforeringar.At a distance in depth, mutually and from the mat H, two perforated choke plates 2 and 3 are arranged inside the mat 4. The choke plates are located one 2 inside the other 3 and so connected to the housing 5 that the entire air flow must pass through first the plate 2 and then plate 3 perforations.
Materialet i fördelningsmattan U utgöres lämpligen av till brandhärdighet impregnerad polyuretanskumplast med öppna celler och en porstorlek av omkring 30 ppi.The material in the distribution mat U is suitably made of fire-impregnated polyurethane foam with open cells and a pore size of about 30 ppi.
Den inre strypplåten 2 är med fördel perforerad väsentligen i sin helhet med en perforeringsgrad som erbjuder 8 - 12, företrädesvis 10 % fria area. Även strypplåten 3 är lämpligen perforerad väsentligen i sin helhet med en perforeringsgrad som erbjuder 3 - 7, företrädesvis 5 % fria area. 10 8201314-5 3 Donets hölje 5 har i sin genombrutna del 6 en per~ forering med en perforeringsgrad som erbjuder 65 - 75 % fri area.The inner throttle plate 2 is advantageously perforated substantially in its entirety with a degree of perforation which offers 8-12, preferably 10% free area. The throttle plate 3 is also suitably perforated substantially in its entirety with a degree of perforation offering 3 - 7, preferably 5% free area. 10 8201314-5 3 The housing 5 of the device has in its perforated part 6 a perforation with a degree of perforation which offers 65 - 75% free area.
Perforeringen utgöres med fördel i de båda stryp- plåtarna 2 och 3 av runda hål med en diameter av 3 - 7 mm, företrädesvis 5 mm.The perforation advantageously consists in the two throttle plates 2 and 3 of round holes with a diameter of 3 - 7 mm, preferably 5 mm.
Höljet har däremot lämpligen en fyrkantperforering, företrädesvis med kvadratiska hål med cza 10 mm hâlsida.The casing, on the other hand, suitably has a square perforation, preferably with square holes with about 10 mm neck side.
Avståndet mellan fördelningsmattan H och stryp- pläæn 3 bör uppgå till minst 5mm.The distance between the distribution mat H and the choke lawn 3 should be at least 5 mm.
De båda strypplåtarna 2 och 3 bör icke ligga närmare varandra än 60 mm.The two throttle plates 2 and 3 should not be closer than 60 mm.
