Opfindelsen angår et apparat til spredning af luft, der fra en i en indervæg i et rum udmundende ventilationskanal strømmer ind i rummet gennem et som gitter udformet luftretningselement med primære gitteråb-5 ninger i sit hovedsagelig vertikalt anbragte hovedplan.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to an apparatus for spreading air flowing from a ventilation duct opening in an interior wall of a room through a lattice-shaped air direction element with primary lattice openings in its generally vertically arranged main plane.
Indblæsning af i forhold til rumluften undertempereret luft i et rum fra dettes indervæg eller loft ved indervæggen mod vinduesvæggen medfører den ulempe, at hvis den indblæste luftstråle har en sådan kastelæng-10 de, at den når frem til vinduesvæggen, vil den nedadret-tede kolde strømning fra vinduet forstærkes, så der opstår et kraftigt træk i rummet, fortrinsvis gulvtræk.Blowing, in relation to the room air, under-tempered air into a room from its inner wall or ceiling at the inner wall against the window wall causes the disadvantage that if the blown air jet has such a pitch that it reaches the window wall, the downward cold will flow from the window is amplified to produce a strong feature of the room, preferably flooring.
Hvis man anbringer et skrivebord ved vinduet, opstår der træk omkring de personer, som arbejder ved dette.If you place a desk at the window, there will be features around the people working on it.
15 Por at få formindsket disse ulemper med træk i sådanne ventilationsanlæg, hvor man anvender kølet tilgangsluft, har man været tvunget til at tilføre luften ved ydervæggen. Et sådant ventilationsanlæg er kostbart, idet man må føre ventilationskanaler frem til ydervæggen og 20 enten indstøbe disse kanaler i bjælkelag eller skjule dem med et underliggende loft. For at hindre træk eller fornemmelsen af træk kan man blive nødt til at anvende frisk luft med en forholdsvis høj indstrømningstemperatur eller lade den friske luft strømme ind i rummet med 25 lav hastighed. Ved en høj indstrømningshastighed kan en luftstråle fra ventilationsåbningen for den friske luft nemlig passere tværs gennem rummet til den væg, hvor vinduet befinder sig, og strømme nedad på dette sted og derved forøge den nedadrettede kolde strømning.15 To reduce these drawbacks with features in such ventilation systems using cooled supply air, it has been forced to supply the air at the outer wall. Such a ventilation system is expensive, since ventilation ducts have to be led up to the outer wall and either embed these ducts in joists or hide them with an underlying ceiling. In order to prevent draft or the sense of draft, fresh air with a relatively high inflow temperature may need to be used or fresh air flow into the room at low speed. Namely, at a high inflow velocity, an air jet from the fresh air vent opening can pass transversely through the space to the wall where the window is located, and flow downward at this location, thereby increasing the downward cold flow.
30 Med udgangspunkt i den indledningsvis omhandlede konstruktion har opfindelsen til opgave at skabe et sådant luftspredeapparat, som hindrer, at luftstrålen fra ventilationsåbningen for den friske luft passerer tværs gennem hele rummet og derved virker til at forøge den 35 kolde nedadstrømning ved ydervæggen. Med opfindelsen tilstræbes der altså at opnå en hensigtsmæssig spredning af den i rummet indstrømmende ventilationsluft, i- 2 149174 * det idéen er, at den fra luftspredeapparatet afgående, opadrettede luftstrøm skal udøve en vis ejektorvirkning på den horisontalt gennem gitterelementet afgående luftstrøm, så denne rives med, hvorved der opnås en hur-5 tig spredning og blanding af luftstrømmene med hinanden og med luften i rummet, hvilket betyder, at kastelængden for den gennem luftspredeapparatet passerende ventilationsluft kan holdes begrænset, så ventilationsluften ikke når frem til ydervæggen.The object of the invention is to create such an air diffuser which prevents the air jet from the ventilation opening for the fresh air passing across the whole space and thereby acts to increase the cold downward flow at the outer wall. The invention thus aims to achieve an appropriate spread of the ventilation air flowing into the room, the idea being that the upwardly directed upward air flow from the air diffuser must exert a certain ejector effect on the horizontally flowing air through the grating element. with which a rapid spreading and mixing of the air flows is achieved with each other and with the air in the room, which means that the throwing length of the ventilation air passing through the air diffuser can be kept limited so that the ventilation air does not reach the outer wall.
10 Til løsning af denne opgave er apparatet ifølge opfindelsen ejendommeligt ved, at elementet ved hin øvre kant har en perforeret flange, der strækker sig ind i kanalmundingen, og at elementet er indstilleligt i forskellige stillinger på en sådan måde, at flangen fri-15 lægges mere eller mindre, og luften derved strømmer gennem elementet ikke blot hovedsagelig vinkelret på dettes hovedplan via de deri beliggende,primære gitteråbninger, men også opad gennem den perforerede flanges huller, hvorved luftretningselementet bestemmer hovedsagelig to 20 udstrømningsretninger, den ene tilnærmelsesvis horisontal og den anden opad.In order to solve this problem, the apparatus according to the invention is characterized in that the element at the upper edge has a perforated flange extending into the channel mouth and that the element is adjustable in different positions in such a way that the flange is released. more or less, and the air thereby flowing not only substantially perpendicular to its main plane through the primary grating openings located therein, but also upwardly through the holes of the perforated flange, the air direction element determining mainly two outflow directions, one approximately horizontal and the other upwardly .
Med denne udformning er der med enkle midler skabt et luftspredeapparat, som opfylder de stillede krav.With this design, an air diffuser is created with simple means that meets the requirements.
I kraft af den indstillelige frilægningsgrad af 25 hullerne i gitterelementets øvre flange opnår man, at elementet i forskellige indregulerede stillinger tilfører en tilsvarende mængde opadrettet luft, hvilket bevirker. tilsvarende varierende grader af ejektorvirkning mellem den opadrettede luftstrøm og den horisontalt for-30 løbende luftstrøm. Dette betyder igen, at den gennem elementets gitteråbninger horisontalt strømmende luft i kraft af nævnte ejektorvirkning kan afbøjes skråt opad, så man opnår den tilstræbte korte kastelængde.By virtue of the adjustable degree of exposure of the 25 holes in the upper flange of the grating element, it is obtained that the element in different regulated positions supplies a corresponding amount of upward air, which causes. correspondingly varying degrees of ejector action between the upward airflow and the horizontally extending airflow. This in turn means that the horizontal air flowing through the element openings through the said ejector effect can be deflected upwardly so as to obtain the desired short throw length.
En fordelagtig udførelsesform for apparatet iføl-35 ge opfindelsen er ejendommelig ved, at elementet danner den forreste væg i en i kanalmundingen indsat kasse, og at det er lejret svingeligt til kassen ved sin nederste 3 1A9174 kant og holdes i indreguleret stilling ved hjælp af en stilleskrue eller et tilsvarende organ.An advantageous embodiment of the apparatus according to the invention is characterized in that the element forms the front wall of a box inserted in the channel mouth, and that it is pivotally mounted to the box at its lower edge and held in a controlled position by means of a adjusting screw or similar means.
Med denne udformning kan man ved blot at dreje indstillingsskruen i den ene eller den anden retning 5 svinge gitterelementet udad eller indad, så flangen og hullerne i denne frilægges mere eller mindre uden for kassens yderkant.With this design, by simply turning the adjusting screw in one or the other direction 5, the lattice element can be pivoted outwards or inwards, so that the flange and holes thereof are exposed more or less outside the outer edge of the box.
Opfindelsen forklares nærmere i det følgende ved en udførelsesform under henvisning til tegningen, hvor 10 fig. 1 viser et vertikalsnit gennem et rum, hvori luftspredeapparatet ifølge opfindelsen er anbragt, fig. 2 apparatet i perspektiv og i større skala, og fig. 3 i endnu større skala et tværsnit langs et 15 plan markeret med linierne 3-3 i fig. 2.The invention will be further explained in the following by an embodiment with reference to the drawing, in which: FIG. 1 shows a vertical section through a space in which the air diffuser according to the invention is arranged; FIG. 2 shows the apparatus in perspective and on a larger scale; and FIG. 3 shows, on an even larger scale, a cross-section along a plane marked by lines 3-3 in FIG. 2nd
På tegningen betegner 1 ydervæggen i et rum med et vindue 2 og en modsat indervæg 3. I sidstnævnte væg udmunder der en ventilationskanal 4 for frisk luft bestemt til indstrømning i rummet. I ventilationskana-20 lens munding befinder der sig en kasse 5, hvis mod rummet vendende forside har et gitterlignende element 6. Kassen 5 er fortil udformet med en flange 7, der som en ramme strækker sig rundt om kassen og er bestemt til at dække kanterne af den åbning i væggen, som 25 kassen er indsat i. Gitterelementet har langs sin nedre kant en indadbøjet flange 8, der strækker sig under en bøjlelignende holder 9, hvorved der dannes et led, som gør det muligt at svinge gitterelementet noget udad og indad omkring dets nedre kant. Gitterelementet 6 30 har foroven en indadrettet flange 10, hvori der findes et antal huller 11, som danner luftudstrømningsåbninger. Gitterelementet har desuden luftgennemstrømningshuller 12. En stilleskrue 14 strækker sig gennem gitteret ind i en mellemvæg 15, som befinder sig 35 i kassen, og der er på skruen anbragt en fjeder 16, som er indspændt mellem gitterelementet 6 og mellemvæggen 15. Ved at dreje skruen 14 i den ene eller 4 1A 917 4 den anden retning kan man svinge gitterelementet udad eller indad, så flangen 10 og de deri anbragte åbninger frilægges mere eller mindre uden for kassens ydre kant.In the drawing, 1 denotes the outer wall of a room with a window 2 and an opposite inner wall 3. In the latter wall, a fresh air vent duct 4 opens for inflow into the room. In the mouth of the ventilation duct 20 is a box 5, the front of which facing the room has a grid-like element 6. The box 5 is formed at the front with a flange 7 which extends around the box as a frame and is intended to cover the edges. of the opening in the wall into which the box is inserted. The lattice element has along its lower edge an inwardly bent flange 8 extending under a hanger-like holder 9, thereby forming a joint which allows the lattice element to swing somewhat outwards and inwards. around its lower edge. The lattice element 6 30 has at the top an inwardly directed flange 10 in which there are a plurality of holes 11 which form air outlet openings. The grille element further has air flow holes 12. A set screw 14 extends through the grille into a middle wall 15 which is located 35 in the box, and a spring 16 is mounted which is clamped between the grille element 6 and the middle wall 15. By turning the screw 14 in one or the other direction, the lattice element can be pivoted outwards or inwards, so that the flange 10 and the openings therein are exposed more or less outside the outer edge of the box.
5 Mellemvæggen 15 strækker sig et stykke nedad fra kassens øvre væg, men ender oven for kassens bund, så der her dannes en gennemstrømningsspalte 17, som strækker sig fra kassens ene sidevæg til den anden.5 The intermediate wall 15 extends downwardly from the upper wall of the box, but ends above the bottom of the box, forming a flow gap 17 extending from one side wall of the box to the other.
Kassens ene sidevæg har en lufttilgangsstuds 18, 10 og gennemstrømningen kan reguleres ved hjælp af et spjæld 19 anbragt på en drejelig aksel 20 forsynet med en krumtap 21. Denne er ved hjælp af en stang 22 forbundet med en krimitap 23 anbragt på en drejelig stang 24. Denne stang har et mejselspor 25 ud for 15 en åbning i gitterelementet 6. Arrangementet muliggør indstilling af spjældet 19 til en mere eller mindre åben stilling, idet man med en mejsel eller skruetrækker drejer stangen 24 i den ene eller den anden retning.The one side wall of the box has an air inlet nozzle 18, 10 and the flow can be controlled by means of a damper 19 arranged on a pivot shaft 20 provided with a crank 21. This is connected by means of a rod 22 to a crimping pin 23 arranged on a pivotal rod 24 This rod has a chisel groove 25 next to 15 an opening in the grid element 6. The arrangement enables the damper 19 to be adjusted to a more or less open position, with the chisel or screwdriver turning the rod 24 in one or the other direction.
20 Det beskrevne apparat virker stort set på følgen de måde. Hvis gitterelementet 6 ved hjælp af stille-skruen 14 er indstillet til den i fig. 3 viste, fuldt optrukne stilling, udstrømmer der luft fra kassen hovedsagelig vinkelret på gitterets plan, dvs. horisontalt 25 ud i rummet fra væggen 3 mod ydervæggen 1. Der opstår derved risiko for, at den kolde luft stryger ned langs ydervæggen og forstærker den nedadrettede kolde strømning fra vinduet 2, så der opstår gulvtræk. Hvis derimod gitteret ved drejning af stilleskruen ·14 og 30 indvirkning fra fjederen 16 svinges til den i fig. 3 stiplet viste stilling, frilægges også de i flangen 10 anbragte, opadrettede luftudstrømningsåbninger 11. Som angivet med pilen 26 i fig. 1 opstår der derved en opadrettet luftstrøm, som bøjer af langs loftet og der-35 ved medriver den luft, som gennem gitteret strømmer ud gennem åbningerne 12. Denne med en pil 27 i fig. 1 angivne luftstrøm blandes med den opadrettede luftstrøm20 The apparatus described largely acts in the following manner. If the lattice element 6 is adjusted to the position shown in FIG. 3, fully drawn out, air flows out of the box mainly perpendicular to the plane of the grid, i.e. horizontally 25 out into the space from the wall 3 towards the outer wall 1. There is thus a risk of the cold air streaking down the outer wall and amplifying the downward cold flow from the window 2 to create flooring. On the other hand, if, by turning the adjusting screw · 14 and 30, the spring 16 is turned from the spring 16 to the position shown in FIG. 3, the upwardly directed air outflow openings 11 located in the flange 10 are also exposed. As indicated by the arrow 26 in FIG. 1, there arises an upward flow of air which deflects along the ceiling and thereby entrains the air flowing through the grating through the openings 12. This with an arrow 27 in FIG. 1 air flow is mixed with the upward air flow
