Description
Luftspreder for fordeling av i et lokale innblåst ventilasjonsluft. Air diffuser for distribution of ventilation air blown into a room.
Foreliggende oppfinnelse vedrører en luftspreder for fordeling av i et lokale innblåst ventilasjonsluft, bestående av en foran en innblåsninigsåpning anbragt sirkulær, skivef ormet skjerm som er ut-ført som en inn mot åpningen vendt kalott eller er forsynt med en utadbøyet kant og som er forskyvbart lagret i åpningens sentrum i et feste som understøttes av en ramme som er forbundet med åpningen og som er utformet med en konisk utvidet munning på en sådan måte at der mellom rammens koniske munning og skjermen oppstår en spalte som danner et ringformet munnstykke for rotasjonssymmetrisk innblåsing av luften. The present invention relates to an air diffuser for distribution of ventilation air blown into a room, consisting of a circular, disc-shaped screen placed in front of an intake opening which is designed as a skull facing the opening or is provided with an outwardly bent edge and which is displaceably stored in the center of the opening in a fixture which is supported by a frame connected to the opening and which is designed with a conically widened mouth in such a way that between the conical mouth of the frame and the screen there is a gap forming an annular nozzle for rotationally symmetrical blowing of the air .
Ved luftspredere av denne art følger In the case of air diffusers of this nature follows
innblåsingsluften helt taket og sekundær-luft fra lokalet innblandes suksessivt fra undersiden. Det har imidlertid vist seg at taket utsettes for nedsmussing ved avset-ning av smussende partikler ved den hef-tige injisering av den forurensede sekun-dærluft. the supply air from the entire ceiling and secondary air from the premises are successively mixed in from the underside. However, it has been shown that the roof is exposed to soiling by the deposition of soiling particles by the violent injection of the contaminated secondary air.
Oppfinnelsen, som tar sikte på å eli-minere denne ulempe, går ut på at den innblåste luft enten aldri treffer taket eller først 1 en betydelig avstand fra inn-blåsingsanordningen. Luftsprederen ifølge oppfinnelsen utmerker seg ved at vinkelen a mellom midtlinjen C gjennom munnstykket og innblåsingsåpningens plan er bestemt av avstanden A til dette plan i henhold til trykket The invention, which aims to eliminate this disadvantage, assumes that the blown-in air either never hits the ceiling or only a considerable distance from the blowing-in device. The air diffuser according to the invention is distinguished by the fact that the angle a between the center line C through the nozzle and the plane of the intake opening is determined by the distance A to this plane according to the pressure
innenfor intervallene I within the intervals I
hvor a er den nevnte vinkel i grader, D er den sirkulære innblåsingsspaltes midlere diameter, A er avstanden til nevnte plan, og B er den ringformede spaltes bredde. where a is the said angle in degrees, D is the circular inlet slot's mean diameter, A is the distance to said plane, and B is the annular slot's width.
Ifølge en egnet utførelse av luftsprederen er munnstykket utført med en noe According to a suitable embodiment of the air diffuser, the nozzle is made with a something
avtagende spaltebredde for opprettholdelse av en konstant strømningshastighet. Skjermen kan nær sitt sentrum hensikts-messig være forsynt med et antall jevnt decreasing gap width to maintain a constant flow rate. The screen can suitably be provided with an even number near its centre
fordelte mindre utblåsingsåpninger for å hindre smussavsetnlng direkte på selve luftsprederen. distributed smaller exhaust openings to prevent dirt depositing directly on the air diffuser itself.
Oppfinnelsen skal beskrives nærmere i tilslutning til tegningen som viser et snitt The invention shall be described in more detail in connection with the drawing which shows a section
av et utførelseseksempel på en luftspreder ifølge oppfinnelsen. of an embodiment of an air diffuser according to the invention.
På tegningen betegner 1 en innblås-ningsåpning i taket 2 og 3 et lokale, hvori ventilasjonsluft skal blåses inn og fordeles ved hjelp av en luftspreder. 5 betegner en med åpningen forbundet ramme for luftsprederen og en innmuringsramme rundt åpningen 1 er betegnet med 6; til denne er luftsprederens ramme festet. En foran innblåsningsåpningen anbragt sirkulær, skivef ormet skjerm er betegnet med 7. Denne er forskyvbart lagret i åpningens sentrum ved hjelp av en på skjermens bakside festet gjenget tapp 8 som griper inn i en likeledes gjenget muffe 9 på et armkors 10. En sirkulær spalte som er dan-net mellom kanten 5a og av rammen 5 og skjermens ytterkant 7a, er betegnet med In the drawing, 1 denotes a blow-in opening in the roof, 2 and 3 a room, into which ventilation air is to be blown in and distributed by means of an air diffuser. 5 denotes a frame connected to the opening for the air diffuser and a walling frame around the opening 1 is denoted by 6; to this the frame of the air diffuser is attached. A circular, disk-shaped screen placed in front of the intake opening is denoted by 7. This is displaceably stored in the center of the opening by means of a threaded pin 8 attached to the back of the screen which engages in a similarly threaded sleeve 9 on an arm cross 10. A circular slot which is formed between the edge 5a and of the frame 5 and the screen's outer edge 7a, is denoted by
11 og danner et ringformet utblåsings-munnstykke. Ifølge oppfinnelsen er skjermen utført som en inn mot åpningen vendt 11 and forms an annular blow-out nozzle. According to the invention, the screen is designed as one facing towards the opening
kalott. Det ringformede munnstykkes bredde B og dets midlere diameter er D. A er skull. The annular nozzle's width B and its mean diameter is D. A is
avstanden mellom takplanet og midtlinjen C gjennom munnstykket. Vinkelen the distance between the roof plane and the center line C through the nozzle. The angle
mellom linjen C og .tak<p>lanet er betegnet between line C and .tak<p>lanet is designated
med a. Ifølge oppfinnelsen bestemmes denne vinkel slik at de ovenfor angitte betin-gelser er oppfylt Innenfor de oppgitte gren-ser for forholdene D : A henholdsvis B : D. with a. According to the invention, this angle is determined so that the conditions stated above are met Within the stated limits for the ratios D : A and B : D respectively.
I det viste tilfelle er skjermen 7 nær sentrum forsynt med et antall jevnt fordelte In the case shown, the screen 7 near the center is provided with a number of evenly distributed
utblåsingsåpninger 12. exhaust openings 12.
