Opfindelsen angår en luftudledningstéfminal for et luftkonditioneririgsanlæg og af den i indledningen til krav 1 angivne art.BACKGROUND OF THE INVENTION This invention relates to an air discharge terminal for an air conditioner rig system and of the kind specified in the preamble of claim 1.
Luftudledningsterminaler for tilførsel af konditioneret luft fra et centralt anbragt luftkonditioneringsapparat til kontorer, skolerum og andre lignende rum i flerrumsbygninger har fundet stigende anvendelse. Sådanne terminaler er sædvanligvis anbragt i loftet af det rum, som skal tilføres luft, eller på gulvet i nærheden af vinduerne. Brugen af sådanne terminaler i rum, hvori men-15 nesker sædvanligvis opholder sig, kræver at den konditionerede luft afgives fra terminalen så stille som muligt, dvs., at støj, 2Air discharge terminals for the supply of conditioned air from a centrally located air conditioner to offices, school rooms and other similar spaces in multi-room buildings have found increasing use. Such terminals are usually placed in the ceiling of the room to be supplied with air, or on the floor near the windows. The use of such terminals in rooms where people usually reside requires that the conditioned air be emitted from the terminal as quietly as possible, i.e.

som udvikles ved brugen af apparatet, skal holdes på et minimum.which is developed when using the appliance must be kept to a minimum.
En terminal, som har fået en stor udbredelse, består af en enhed til regulering af mængden af konditioneret luft, som afgives til det rum, der skal konditioneres i overensstemmelse med brugerens 5 aktuelle temperaturkrav. En sådan luftreguleringsenhed indbefatter en opblæselig bælg, hvis opblæsningsgrad varierer i omvendt forhold med mængden af konditioneret luft, som afgives fra terminalen.A widespread terminal consists of a unit for controlling the amount of conditioned air which is delivered to the room to be conditioned in accordance with the user's current temperature requirements. Such an air control unit includes an inflatable bellows whose degree of inflation varies inversely with the amount of conditioned air emitted from the terminal.
10 Den konditionerede luft tilføres gennem passende kanaler hver terminal fra en central stationær kølemaskine. Hver terminal har en cirkulationsdel, der er forbundet med en tilførselskanal. Terminalen har desuden et fordelerkammer med deri anbragt luftreguleringsenhed. En plade med et antal åbninger er indskudt imel-15 lem cirkulationsdelen og fordelerkammeret.10 The conditioned air is supplied through appropriate ducts each terminal from a central stationary refrigeration machine. Each terminal has a circulation portion connected to a supply duct. In addition, the terminal has a distribution chamber with air control unit located therein. A plate having a plurality of openings is interposed between the circulation member and the distributor chamber.
I de kendte terminaler dannedes to adskilte luftstrømme i terminalen. De separate luftstrømme strømmede nedad gennem terminalen og blev afgivet fra enheden gennem to separate afgangs.spalter.In the known terminals, two separate air streams were formed in the terminal. The separate air streams flowed down the terminal and were discharged from the unit through two separate outlet slots.
20 I nyere terminaler er det blevet anset for ønskeligt at forøge mængden af afgivet konditioneret luft for at imødekomme kravene ved visse anlæg. Det er blevet nødvendigt at tilvejebringe en anden luftreguleringsenhed for at kunne øge mængden 25 af luft, der strømmer igennem anlægget. Den anden enhed har et par luftkanaler parallelt med den første enheds kanal. Luften, som strømmer gennem åbningen, der er reguleret af de opblæse-lige bælge, udsættes for et trykfald. Trykforskellen virker på luftreguleringsenhederne, hvilket medfører vibrationsbevægel-30 ser. Når terminalerne kun indeholder én luftreguleringsenhed, kunne støjen frembragt af denne vibrationsbevægelse accepteres .In newer terminals, it has been considered desirable to increase the amount of conditioned air released to meet the requirements of certain plants. It has become necessary to provide another air control unit to increase the amount of air flowing through the system. The second unit has a pair of air ducts parallel to the first unit duct. The air flowing through the aperture regulated by the inflatable bellows is subjected to a pressure drop. The pressure difference acts on the air control units, which causes vibration movements. When the terminals contain only one air control unit, the noise generated by this vibration movement could be accepted.

Følgelig vil den fremkaldte støj fra en sådan vibrationsbevægelse hos to enheder medføre uønsket støj i det rum, der skal 5 konditioneres. Det er defor vigtigt, at vibrationsbevægelser mellem enhederne elimineres.Accordingly, the evoked noise from such vibration movement of two units will cause undesirable noise in the room to be conditioned. It is therefore important that vibration movements between the devices are eliminated.
Da fire separate luftstrømme dannes i terminalen, og da den kun har to udstrømningsspalter, er det nødvendigt, at de delte 10 luftstrømme samles opstrøms for udstrømningsspalterne. Da luften strømmer med en forholdsvis stor hastighed, vil ukon-troleret blanding af luftstrømmene medføre turbulens og derved formindske virkningen af terminalens funktion, og desuden vil der kunne opstå uønsket støj.Since four separate air streams are formed in the terminal and since it has only two outflow slots, it is necessary for the shared 10 air streams to be pooled upstream of the outflow slots. As the air flows at a relatively high velocity, uncontrolled mixing of the air currents will cause turbulence, thereby reducing the effect of the terminal's function, and in addition, undesirable noise may occur.

Det er den foreliggende opfindelses formål at anvise en luftudledningsterminal som tillader en stor udstrømning af konditioneret luft, og hvor støj reduceres til et minimum eller helt elimineres.It is the object of the present invention to provide an air discharge terminal which allows a large outflow of conditioned air and where noise is reduced to a minimum or completely eliminated.
2020
Dette formål tilgodeses ved, at den indledningsvist omtalt luftudledningsterminal er ejendommelig ved det i den kendetegnende del af krav 1 anførte.This object is met by the fact that the initially mentioned air discharge terminal is characterized by the characterizing part of claim 1.
Ved udstrømningsåbningen findes således to styk dæmpningsor-25 ganer. Afstivningsdelen er forbundet med dæmpningsorganerne og med en ikke bevægelig del af terminalen for derved at forhindre en relativ bevægelse mellem enhederne og den ikke-bevæge-lige faste del, hvorved dæmpningsenhedernes vibrationsbevægelse forhindres i forhold til terminalens faste del, hvilken 30 vibrationsbevægelse ellers ville fremkalde støj. Afstivningsdelen forhindrer således denne vibrationsbevægelse og dermed den uønskede støjdannelse.Thus, at the outlet opening there are two damping means. The stiffener portion is connected to the damping means and to a non-movable portion of the terminal thereby preventing relative movement between the units and the non-movable solid portion, thereby preventing the vibration movement of the damping units relative to the fixed portion of the terminal, which would otherwise cause noise . Thus, the stiffening member prevents this vibration movement and thus the undesirable noise formation.
Ved den angivne udformning dannes fire i det væsentlige paral-35 lelt forløbende luftkanaler og selve udløbsåbningen er herved udformet som en sprederdel bestående af to sprederorganer og en sprederdel anbragt mellem sprederorganerne til dannelse af to sprederudstrømningsspalter. De to sprederorganer har en bu- 4In the design disclosed, four substantially parallel air ducts are formed and the outlet opening itself is hereby formed as a spreader portion consisting of two spreader means and a spreader portion disposed between the spreader means to form two spreader outflow slots. The two spreader means have a bu-4

Den herved opnåede jævne luftstrøm medvirker endvidere til at forhindre tab af virkningsgrad ved luftterminalens drift.The even flow of air thus obtained helps to prevent loss of efficiency in the operation of the air terminal.

Ved at afstivningsdelen i overensstemmelse med det i den kendetegnende del af krav 2 anførte er af et fjederagtigt materiale, kan man tilgodese konstruktionstolerancer uden at reducere afstivn ingssdelens virkningsgrad med hensyn til at for- „c hindre reguleringsenhedens vibrationsbevægelse, i oBy providing that the stiffening member according to the characterizing part of claim 2 is of a spring-like material, construction tolerances can be satisfied without reducing the stiffness of the stiffening part in order to prevent the vibration movement of the control unit,
Ved den i den kendetegnende del af krav 3 angivne kombination af siderne af den som en ligebent trekant formede del og de buede dele ændres retningen for luftstrømmen fra reguleringsenhederne gradvist hen imod udstrømningsspalterne. Ved at be- 20 nytte en sådan gradvis retningsændring i stedet for en brat retningsændring reduceres turbulensen i luftstrømmen, hvorved terminalens virkningsgrad forøges, og støjdannelse forhindres.With the combination of the sides of the portion formed as a straight triangle and the curved portions as defined in the characterizing part of claim 3, the direction of the air flow from the control units gradually changes towards the outflow slots. By utilizing such a gradual change of direction instead of a sudden change of direction, turbulence in the airflow is reduced, thereby increasing the efficiency of the terminal and preventing noise formation.
Den i den kendetegnende del af krav 4 angivne ledeskærm styrer 25 de luftstrømme, der strømmer ind i blanderummet, ad parallelstrømningsve je . Dette arrangement begrænser yderligere dannelse af turbulens, når luftstrømmene blandes i blanderummet, hvorved luftterm i nalens virkningsgrad forøges, og støjdannelsen forhindres.The guiding shield as defined in the characterizing part of claim 4 controls the airflows flowing into the mixing chamber by parallel flow paths. This arrangement further limits the formation of turbulence as air flows are mixed into the mixing chamber, thereby increasing the air term in the efficiency of the needle and preventing the formation of noise.

Figurerne viser en foretrukken udførelsesform for en luftud-1 edn ingsterminal 10 ifølge opfindelsen. Terminalen 10 er indrettet til at monteres i loftet af et luftkonditioneret rum.The figures show a preferred embodiment of an air supply terminal 10 according to the invention. The terminal 10 is arranged to be mounted in the ceiling of an air-conditioned room.
® Terminalen 10 er en del af et luftkonditioneringsanlæg, som indeholder et centralt placeret luftkonditioneringsapparat, der kan have et filter, en forkølingsspiral, sprøjteorganer, en køleslange, varmespiral og en blæser til luftopvarmning, -afkøling, -affugtning, -befugtning og -filtrering. En blæser fordeler den konditionerede luft gennem fordelingskanaler anbragt til at levere konditioneret luft til luftkonditioneringsterminaler, der er anbragt rundt omkring i en bygning.The terminal 10 is part of an air conditioner which includes a centrally located air conditioner which may have a filter, a cooling coil, spraying means, a cooling hose, heat coil and a fan for air heating, cooling, dehumidification, humidification and filtration. A blower distributes the conditioned air through distribution channels arranged to supply conditioned air to air conditioning terminals disposed around a building.
Terminalen 10 har et første kammer eller en cirkulationsdel 15 12, som er foret med lydabsorberende materiale 14, såsom glasfiber. Cirkulationsdelen er sædvanligvis åben i begge ender til forbindelse af en række adskilte terminaler til dannelse af et komplet luftfordelingssystem. Passende endestykker (ikke vist) anvendes til at afslutte terminalerne i en serie.Terminal 10 has a first chamber or circulation portion 15 12 which is lined with sound-absorbing material 14, such as fiberglass. The circulation member is usually open at both ends for connecting a series of separate terminals to form a complete air distribution system. Appropriate end pieces (not shown) are used to terminate the terminals in a series.
20 En lufttilførsels- og fordelerplade 16 har et antal åbninger 18 og er anbragt til jævnt at fordele tilført luft fra cirkulationsdelen 12 til et fordelingskammer 22, som er afgrænset af fordelingspladen 16's top- og sidevægge.An air supply and distributor plate 16 has a plurality of openings 18 and is arranged to evenly distribute supply air from the circulation member 12 to a distribution chamber 22 bounded by the top and side walls of the distribution plate 16.

Fordelingskainmeret 22's bund har indbyrdes flugtende reguleringsplader 24. Disse plader samvirker med efter valg opblæselige bælge eller blærer 26 og 28 til dannelse af et par luftregulerings- eller dæmpningsenheder. Blærerne 26 og 28 har, når de er fuldt opblæste, en typisk pæreform. Hver blære er klæ-30 bet fast på en central skillevægsamling bestående af modsatte konvekse plader 30 og 31. Disse plader har en V-formet fordybning, således at blærerne ligger fuldt tilbagetrukket inden for pladerne, når blærerne er tømt for luft. Dette tilvejebringer et stort område imellem blærernes aktive vægge 32 og reguleringspladerne 35 for maksimal luftstrøm derimellem. Den tilbagetrukne blære danner endvidere en glat overflade langs med pladerne 30 og 31 til formindskelse af luftturbulens. Blærernes vægge 32 er normalt konkave. Når blærerne er fuldstændigt lufttomme og sammenklappede, 6The bottom of the distribution chamber 22 has mutually regulating plates 24. These plates cooperate with inflatable bellows or blisters 26 and 28 to form a pair of air control or damping units. The bladders 26 and 28, when fully inflated, have a typical bulb shape. Each bladder is adhered to a central partition assembly consisting of opposite convex plates 30 and 31. These plates have a V-shaped recess so that the bladders are fully retracted within the plates when the bladders are emptied of air. This provides a large area between the active walls 32 of the bladders and the regulating plates 35 for maximum air flow therebetween. The retracted bladder further forms a smooth surface along the plates 30 and 31 to reduce air turbulence. The walls 32 of the bladders are usually concave. When the blisters are completely airy and collapsed, 6

er blærernes aktive vægge udenfor luftstrømmen for at formindske muligheden for vibrationer i blærerne. Ved at forsænke blærerne i pladerne 30 og 31 og ved at blærerne har konkave vægge 5 32 forøges afstanden imellem reguleringspladerne og blærernes væg 32. Derved dannes en større åbning imellem blærerne og reguleringspladerne, når blærerne er helt toirme og sammenklappede for maksimal luftstrøm derimellem. En stor bevægelse af væggen 32 fra den konkave stilling til en konveks stilling kan opnås uden at strække blærematerialet. Pladerne 30 og 31 har åbninger 35 med spalte til optagelse af passende organer, såsom skruer eller bolte,til at forbinde pladerne med ikke viste endeplader.are the active walls of the bladders outside the airflow to reduce the possibility of vibration in the bladders. By lowering the blisters in the plates 30 and 31 and by the blisters having concave walls 5 32, the distance between the control plates and the walls of the blades 32 is increased, thereby creating a larger opening between the blisters and the control plates, when the blisters are fully formed and collapsed for maximum air flow therebetween. A large movement of the wall 32 from the concave position to a convex position can be achieved without stretching the bladder material. The plates 30 and 31 have openings 35 with slots for accommodating suitable means, such as screws or bolts, for connecting the plates with end plates not shown.
Et sprederorgan består af sidesprederdelene 36, der har udad 15 buede nedre sidevægge 38 og en midtersprederdel 40. Sprederdelene er på passende måde forbundet med et forbindelsesstykke 42 for at samle de tre sprederdele til en underenhed. Fortrinsvis er der i terminalen efter luftregulerings- og dæmpningsenhederne anbragt lydabsorberende materiale, såsom 2 0 g 1 asf iberplader 41. Pladerne 41 danner apparatets ydervægge. Fiberpladerne absorberer lydbølger af middel og høj frekvens. Pladerne er ikke effektive til at absorbere og dæmpe lyd i 1avfrekvensområdet.A spreader means consists of the side spreader portions 36 which have outwardly curved lower side walls 38 and a center spreader portion 40. The spreader portions are suitably connected to a connector 42 to assemble the three spreader portions into a sub-unit. Preferably, sound-absorbing material, such as 20 g of asphalt sheets 41, is arranged in the terminal after the air control and damping units 41. The plates 41 form the outer walls of the apparatus. The fiberboard absorbs medium and high frequency sound waves. The plates are not effective in absorbing and attenuating sound in the frequency range.
Den ovenfor beskrevne loftterminal er i hovedsagen af kendt art. Forskellen imellem den beskrevne terminal og terminalen ifølge den kendte teknik er den viste tilføjelse af en anden luftreguleringsenhed. For at tilfredsstille mange brugeres ønsker har man fundet, at det er nødvendigt at forøge mængden 30 af konditioneret luft, som kan strømme ud fra terminalen. Tidligere har terminalen af den omhandlede art kunnet levere en maksimal luftmængde på ca. 5,7 m3/min.The ceiling terminal described above is essentially of a known kind. The difference between the described terminal and the terminal according to the prior art is the shown addition of another air control unit. In order to satisfy the wishes of many users, it has been found that it is necessary to increase the amount of conditioned air which can flow out of the terminal. Previously, the terminal of the kind in question was able to deliver a maximum airflow of approx. 5.7 m3 / min.
For effektivt at kunne regulere udstrømningen af en forøget 35 mængde konditioneret luft har det været nødvendigt at anvende en anden luftregulerings- eller dæmperenhed. Denne enhed danner en tredje og fjerde strømningskanal parallelt med de kanaler for konditioneret luft bestemt af den første luftregu- 7 \In order to effectively control the outflow of an increased amount of conditioned air, it has been necessary to use another air control or damper unit.

As noted above, the second unit has a pair of cut or control plates 24, bladders 26, 28 and a partition assembly with a pair of convex plates 30, 31.
5 I luftkonditioneringsterminaler af den beskrevne art er det vigtigt, at støjniveauet holdes så lavt som muligt, da terminalerne typisk anvendes til at tilføre beboelses- og kontorrum luft. I enheder med en enkelt luftreguleringsenhed har hidtil enhver vibrationsbevægelse af enheden, hvorved lavfrekvensstøj kunne 10 frembringes, enten være ubemærket eller tolereret, da støjen har ligget på et minimalt niveau. Vibrationsbevægelsen af luftreguleringsenhederne er fremkommet ved trykforskel opstået som følge af, at luften passerer gennem åbningerne, som er dannet imellem pladerne 24 og blærerne 26, 28. Imidlertid har indfø-15 ringen af en anden enhed intensiveret lavfrekvensstøjen, som frembringes på grund af vibrationsbevægelse af hver af enhederne. Det må antages, at den forøgede støj, der frembringes på den nævnte måde, skyldes resonans imellem de to enheder. Følgelig er det vigtigt, at enhedernes vibrationsbevægelse hidrø-20 rende fra luftstrøm gennem disse formindskes eller elimineres.5 In air conditioning terminals of the type described, it is important that noise levels are kept as low as possible, since the terminals are typically used to supply air in living and office space. In units with a single air control unit, so far, any vibrational movement of the unit whereby low frequency noise could be produced is either unnoticed or tolerated since the noise has been at a minimal level. The vibrational movement of the air control units is caused by pressure difference caused by the air passing through the openings formed between the plates 24 and the bladders 26, 28. However, the introduction of another unit has intensified the low frequency noise produced by vibrational movement of the each of the units. It is believed that the increased noise produced in the said manner is due to resonance between the two units. Accordingly, it is important that the vibration movement of the units resulting from air flow through them is diminished or eliminated.
For at opnå dette er en afstivningsdel 70 forbundet med luft reguleringsenhederne og en ikke bevægelig del af terminalen, f. eks. en flange 72. Afstivningsdelen 70 er vist som fremstillet 25 af et i det væsentlige fjerderlignende materiale. Afstivningsde len indgriber med opadragende arme 74 af hver konvekse enheds plader 30, 31, og er fast forbundet med flangen 72. Afstivningsdelen 70 er i direkte kontakt med armene 74's ydre overflader og med flangen 72's ydre overflade for at forhindre 30 enhver bevægelse af enhederne i et vandret plan. Man har iagtta get, at i hovedsagen hele enhedens uønskede bevægelse sker i et vandret plan. Ved at fastholde luftreguleringsenhederne på den beskrevne måde forhindres de i at bevæge sig i for hold til terminalens stationære dele. Eliminering af enhedernes 35 vibrationsbevægelse eliminerer lavfrekvensstøj fra terminalen.To achieve this, a stiffener portion 70 is connected to the air control units and a non-movable portion of the terminal, e.g., a flange 72. The stiffener portion 70 is shown as manufactured from a substantially spring-like material. The stiffener portion engages with upwardly extending arms 74 of each convex unit's plates 30, 31, and is firmly connected to the flange 72. The stiffener portion 70 is in direct contact with the outer surfaces of the arms 74 and with the outer surface of the flange 72 to prevent any movement of the units in a horizontal plane. It has been observed that in the main, the entire unwanted movement of the device occurs in a horizontal plane. By holding the air control units in the manner described, they are prevented from moving relative to the stationary parts of the terminal. Eliminating the vibration movement of the devices eliminates low frequency noise from the terminal.
Den heri beskrevne terminal har en lodret midtervæg 43, som er anbragt i hovedsagen på terminalens lodrette akse. Væggen adskil- 8The terminal described herein has a vertical center wall 43 which is disposed substantially on the vertical axis of the terminal. The wall separates 8

Fire separate luftstrømme tilvejebringes således i enheden nedstrøms fra luftreguleringsdæmperne. Det er nødvendigt, at sådanne luftstrømme kombineres for korrekt udstrømning gennem luftudstrømningsspalteme, dannet imellem sidesprederdelene 36 og midterspreéerdelen 10 40. For at forhindre virkningstab og desuden for at for hindre frembringelse af støj, må blandingen af disse luftstrømme ske uden unødvendig turbulensdannelse.Thus, four separate air streams are provided in the unit downstream of the air control dampers. It is necessary that such airflows be combined for proper outflow through the airflow gaps formed between the side spreader portions 36 and the center diffuser portion 10 40. In order to prevent loss of power and, in addition, to prevent noise generation, the mixing of these airflows must occur without undue turbulence.
Da udstrømningsspalterne i hovedsagen er på linie med midtervæggen 43 15 er det nødvendigt, at de luftstrømme, som strømmer gennem de ydre luftkanaler 46 og 48, bliver rettet radialt indad for at samles med de luftstrømme, der strømmer gennem de indre kanaler 50 og 52. Spredersidevæggene 36 er buet ved deres øvre ende 37 til korrekt styring af luftstrømmene radialt indad. Ved at bue si- 20 despredervæggene på den beskrevne made møder luftstrømmene buede overflader, som gradvist styrer luften i den ønskede retning.Since the outflow gaps are substantially in line with the middle wall 43, it is necessary that the air streams flowing through the outer air ducts 46 and 48 are directed radially inwardly to coalesce with the air streams flowing through the inner ducts 50 and 52. The spreader side walls 36 are curved at their upper end 37 to properly control the air flows radially inward. By arching the side diffuser walls in the manner described, the air currents encounter curved surfaces which gradually control the air in the desired direction.
Midtervæggen 43 indbefatter en del 54, der er fastgjort til dens nedre overflade. Delen 54 har sider 56 og 58, som befin-25 der sig i afstand over den øvre, indre overflade af sidesprederdelene til derimellem at danne sektioner til strømlinet styring af den derigennem strømmende luft og til at styre luften ad en i det væsentlige 45°'s strømningsbane imod blanderummet 60. Ved gradvist at ændre strømningsretningen for den luft, der ledes 30 ind i blanderummet 60, holder turbulens, som frembringes på grund af blandingen ved et minimum.The middle wall 43 includes a portion 54 attached to its lower surface. The portion 54 has sides 56 and 58 which are spaced apart from the upper inner surface of the side spreading portions to form sections therebetween for streamlining the flow of air therethrough and for controlling the air at a substantially 45 °. s flow path toward the mixing chamber 60. Gradually changing the flow direction of the air conducted 30 into the mixing chamber 60 maintains turbulence produced by the mixing at a minimum.
Delen 54 er i det væsentlige formet som en ligebenet trekant med lige lange sider 56 og. 58, der strækker sigidet væsentli-33 ge parallelt med den buede del 37 af sidesprederdelens overflade, som er anbragt med afstand umiddelbart ud for herfor. Siderne 56 og 58 styrer ved samvirke med de buede dele af sidesprederne gradvis luftstrømmene nedad imod afgangsspalteme for at begrænse turbulens,The portion 54 is substantially shaped as an equilateral triangle with equal long sides 56 and. 58 extending substantially the sidewall 33 parallel to the curved portion 37 of the side spreader portion, spaced immediately adjacent to it. The sides 56 and 58, in conjunction with the curved portions of the side spreaders, gradually control the air flows downward towards the outlet slots to limit turbulence.

9 der ellers ville dannes, hvis luftstrømmene pludselig blev rettet i en anden retning.9 that would otherwise form if the air currents were suddenly directed in a different direction.
5 Selv om separat del 54 er vist, vil det forstås, at væggen 43" s flade kan være passende udformet til at danne de nødvendige sider 56 og 58.Although separate part 54 is shown, it will be appreciated that the surface of the wall 43 "may be suitably formed to form the required sides 56 and 58.
Man har fundet, at for at opnå i hovedsagen ensartet luftstrøm 10 fra de to afgangsspalter, skal de forskellige luftstrømme, der frembringes i terminalen, blandes opstrøms for spalterne.It has been found that in order to obtain substantially uniform air flow 10 from the two outlet slots, the different air flows generated in the terminal must be mixed upstream of the slots.
For yderligere at begrænse turbulens dannet ved de forskellige 15 luftstrømmes blanding har delen 54 desuden en lodret ledeskærm 62, der strækker sig nedad fra delen 54's laveste punkt og ind i blandingskammeret 60. Ledeskærmen 62 styrer den luftstrømsdel·, som rammer den i en i hovedsagen lodret strømningsbane. De luftstrømme, der strømmer fra kanalerne 46 og 52, bliver således rettet 20 parallelt med de luftstrømme, der kommer fra kanalerne 48 og 50, når luftstrømmene kommer ind i blandingskammeret 60. Ledeskærmen 62 er fortrinsvis fremstillet af et lydabsorberende materiale.In addition, to further limit turbulence formed by the mixing of the various air streams, the portion 54 has a vertical guide shield 62 extending downwardly from the lowest point of the portion 54 into the mixing chamber 60. The guide screen 62 controls the airflow portion vertical flow path. Thus, the air streams flowing from the ducts 46 and 52 are directed parallel to the air streams coming from the ducts 48 and 50 as the air streams enter the mixing chamber 60. The guiding shield 62 is preferably made of a sound-absorbing material.
Ved at rette luftstrømmene i parallelle strømningsbaner, når strømmene kommer ind i rummet 60, begrænses den ved disse strømmes 25 blanding dannede turbulens yderligere.By directing the air currents in parallel flow paths as the currents enter the space 60, the turbulence generated by the mixture of these currents 25 is further limited.
Ved den foreliggende opfindelse er det således også muligt at forsyne udstrømningsåbningerne med yderligere dæmperenheder, hvor de regulerede luftstrømme ledes hen imod et enkelt 30 blanderum. Det er også muligt at variere udformningen af afstivningsdelen til at forhindre enhedernes relative bevægelse.Thus, in the present invention, it is also possible to provide the outlet openings with additional damper units where the controlled air flows are directed towards a single mixing chamber. It is also possible to vary the design of the stiffener to prevent the relative movement of the units.
Den foregående opbygning tillader sammenblanding af fire eller flere separate luftstrømme uden for frembringelse af unødig 35 turbulens.The foregoing structure permits mixing of four or more separate air streams without generating unnecessary turbulence.
