Description
DK 159942 BDK 159942 B
Opfindelsen angår et ventilationsapparat til ventilation af et stuerum, hvilket apparat er indrettet til at monteres i eller ved en yderluftsåbning i stuerummet.The invention relates to a ventilation apparatus for ventilating a living room, which apparatus is adapted to be mounted in or at an external air opening in the living room.
De kendte ventilationsapparater er i almindelighed konti-5 nuerligt arbejdende, og luftens strømningsretning i dem er konstant, hvorfor der i princippet kræves to apparater til hvert rum, som skal ventileres, hvoraf det ene bisser forbrugt luft ud fra stuerummet, og det andet bisser frisk luft ind i stedet. Begge apparaterne 10 omfatter forskellige luftbehandlingstrin, f.eks. filtre ring, opvarmning, fugtning, køling osv. Af apparaterne er dannet et system, i hvilket en del af funktionerne (f.eks. akkumulering af varme) er slået sammen og udblæsningsanordningen og indblæsningsanordningen sammenbyg-15 get, men der er alligevel tale om to separate apparater.The known ventilators are generally continuously operating and the flow direction of the air in them is constant, which is why in principle two appliances are required for each room to be ventilated, one of which consumes air from the living room and the other a bit of fresh air. air into the place. Both apparatus 10 comprise various air treatment steps, e.g. filters, heating, humidification, cooling, etc. A device is formed in which a part of the functions (eg accumulation of heat) is combined and the exhaust device and the inlet device are combined, but they are nevertheless two separate appliances.
Ventilationen af et stuerum forudsætter ikke, at apparaterne er i gang kontinuerligt. Apparaterne kan også fungere periodevis, hvorved man klarer sig med et apparat, som skiftevis blæser luft ud fra rummet og blæser frisk 20 luft ind i rummet. Et sådant apparat er f.eks. kendt fra FI-PS 56 742. Det beskrevne apparat har imidlertid flere svagheder. For det første kan luften ikke filtreres, eftersom støvet, som samles i filtret, ved en omstyring af strømningsretningen ville frigøres og vende 25 tilbage til rummet. Som følge af savnet af et filter skal man for at forhindre tildækning af varmeakkumula-toren gøre brug af en stor afstand mellem pladerne, hvilket for opnåelse af en tilstrækkelig varmekapacitet og varmeledningskoefficient fører til en stor pladetyk-30 kelse og -længde. Til forbedring af varmeledningskoef- ficienten har man foreslået at rykke eller bukke pladerne. Apparatet bliver på grund af varmeakkumulatorens størrelse i sin helhed stor, dyr og vanskelig at placere, og dets anvendelse begrænses til sådanne tilfælde, 2 DK 'K. 9"'? 3 hvor både yder- og inderluften er så rene, at de ikke behøver filtreres, eller når luftfiltrering af andre grunde ikke kræves.The ventilation of a living room does not require that the appliances are continuously operating. The appliances can also function periodically, making it possible to use an apparatus that alternately blows air out of the room and breathes fresh air into the room. Such an apparatus is e.g. known from FI-PS 56 742. However, the described apparatus has several weaknesses. First, the air cannot be filtered, as the dust collected in the filter would, by reversing the flow direction, be released and return to space. Due to the lack of a filter, in order to prevent the coverage of the heat accumulator, a large distance between the plates must be used, which in order to obtain a sufficient heat capacity and heat conduction coefficient leads to a large plate thickness and length. In order to improve the coefficient of heat conduction, it has been proposed to move or bend the plates. The apparatus, due to the size of the heat accumulator as a whole, becomes large, expensive and difficult to place, and its use is limited to such cases, 2 DK 'K. 9 "'? 3 where both the outer and inner air are so clean that they do not need to be filtered or when air filtration for other reasons is not required.
Apparatet fungerer heller ikke på den måde,som opfinde-5 ren har anført. Al varmeenergi kan kun opsamles i de tilfælde, hvor inderluften køler til nøjagtig yderluftens temperatur og yderluften på tilsvarende måde opvarmes til nøjagtig samme temperatur som inderluften, men det sker ikke i praksis.Also, the apparatus does not operate in the manner stated by the inventor. All heat energy can only be collected in cases where the inner air cools to the exact outside air temperature and the exterior air is heated to exactly the same temperature as the inner air, but this does not happen in practice.
10 Begrænsningen af anvendelsen af filter samt det, at man i publikationen ikke engang har forsøgt at beskæftige sig med spørgsmålet om, hvorledes luften effektivt kan fordeles i stuerummet og fjernes derfra, har ført til, at apparatet ifølge publikationen ikke findes i 15 brug.10 The restriction on the use of filters and the fact that the publication has not even attempted to deal with the question of how the air can be effectively distributed in the living room and removed from it has led to the apparatus according to the publication not being in use.
Der kendes også sådanne apparater, som omfatter to varne-akkumulatorer, hvor indblæsningsluft strømmer gennem den ene og udblæsningsluft gennem den anden. Både på yderluftssiden og inderluftssiden findes et skiftespjæld-20 system, ved hjælp af hvilket luftens strømningsretning omstyres med ca. 1 minuts mellemrum. Udblæsningen og indblæsningen af luft sker med to separate ventilatorer, som begge er sluttet til et luftfordelingskanalsystem. Anordningen bliver herved relativ kompliceret, dyr og 25 let udsat for forstyrrelser, og den adskiller sig kun fra traditionelle systemer med kontinuerlig drift hvad angår varmeakkumulatoren. Også selve akkumulatoren er i almindelighed løst på en enklere måde ved at udføre den i form af en roterende tromle, i hvis ene halvdel 30 yderluft og anden halvdel inderluft kontinuerligt strøm mer .Such devices are also known, which comprise two warning accumulators, in which blow-in air flows through one and blow-out air through the other. Both on the exterior air side and the inner air side there is a shift damper system by which the flow direction of the air is reversed by approx. 1 minute intervals. The exhaust air and the inlet are provided with two separate fans, both of which are connected to an air distribution duct system. The device is thus relatively complicated, expensive and easily subject to interference, and it differs from traditional systems with continuous operation in terms of the heat accumulator. Also, the accumulator itself is generally solved in a simpler way by performing it in the form of a rotating drum, in which one half of 30 external air and the other half of internal air continuously flows.

3 apparat, som eliminerer de førnævnte ulemper og er kendetegnet af en enkel konstruktion, ringe størrelse, let placering, effektiv luftfordeling i stuerummet og høj temperaturvirkningsgrad. Dette opnås med et ventilator-5 apparat ifølge opfindelsen, som er ejendommeligt ved det i krav l's kendetegnende del angivne.3 apparatus, which eliminates the aforementioned disadvantages and is characterized by a simple construction, small size, easy placement, efficient air distribution in the living room and high temperature efficiency. This is achieved with a fan apparatus according to the invention, which is characterized by the characterizing part of claim 1.
Opfindelsen er baseret på den ide, at apparatet monteres direkte i en normal vinduesåbning i et udluftningsvindue, hvorfor den ikke kræver separat plads i bygnin-10 gen eller ekstra åbninger i ydervægge eller loft. Stue rummet kan trods dette udluftes på sædvanlig måde direkte via udluftningsvinduet, når en hurtig udluftning ønskes. Også herved kommer yderluften filtreret ind i stuerummet, mens filterdelen forbliver tilbage i vin-15 duesåbningen, når filtrering udnyttes i apparatet.The invention is based on the idea that the apparatus is mounted directly in a normal window opening in a vent window, so it does not require separate space in the building or additional openings in exterior walls or ceiling. Nevertheless, the living room can be vented in the usual way directly via the vent window when a rapid vent is desired. Also, the exterior air enters filtered into the living room, while the filter portion remains in the window opening when filtration is utilized in the apparatus.
Opfindelsen gør det muligt at anvende apparatet som et kombineret udblæsnings- og indblæsningsapparat, hvorved forskydeligheden af apparatet eller dets del letter vedligehold af filteret, varmeakkumulatoren, ventila-20 toren osv.The invention makes it possible to use the apparatus as a combined exhaust and supply apparatus, whereby the displacement of the apparatus or its part facilitates maintenance of the filter, the heat accumulator, the fan, etc.
Hvis apparatets lu ftfordelingskanal indrettes til at ligge over vinduesåbningen, og kanalens forside udformes til et gardinbræt, kan ventilationskanalen skjules i form af en i lejligheden normal befindende del. Hvis 25 gardinbrættet gøres let aftageligt, kan hele kanalen let rengøres, hvilket væsentligt forbedrer apparatets hygiejne i sammenligning med kendte anordninger.If the appliance's air distribution duct is arranged to lie above the window opening and the front of the duct is formed into a curtain board, the ventilation duct can be concealed in the form of a normal part of the apartment. If the curtain board is made easily removable, the entire duct can be easily cleaned, which significantly improves the hygiene of the apparatus in comparison with known devices.
; Når udblæsningen af stueluften og indblæsningen af yder- luften sker gennem huller i gardinbrættet, kan disse 30 fordeles over et stort område, hvorved man til og med med en ringe indblæsningshastighed opnår en effektiv skylning af stuerummet, hvilket væsentligt mindsker; When the exhaust of the living room air and the supply of the outside air is through holes in the curtain board, these 30 can be distributed over a large area, thereby even achieving a low airflow rate, which effectively reduces the room's flushing, which significantly reduces

risikoen for irsk, og forbedrer ventilationssystemets effektivitet i forhold til kendte systemer. Dertil forhindrer ventilationen takket vsre placeringen og retningen af hullerne en kold luftstrøm fra vinduet, som 5 forårsager f.eks. vinduestrak.the risk to Irish, and improves the efficiency of the ventilation system compared to known systems. In addition, thanks to the location and direction of the holes, ventilation prevents a cold air flow from the window, which causes e.g. window pulled.
Opfindelsen muliggør også en enkel måde til at opnå befugtning vintertid og afkøling sommertid, som forklaret nærmere i det følgende. Opfindelsen skal herefter beskrives nærmere med henvisning til tegningen, 10 hvorpå: fig. 1 viser i lodret snit en fordelagtig udførelses-form for et apparat ifølge opfindelsen fungerende som et udblssningsapparat, fig. 2 viser det samme som fig. 1 med apparatet fun-15 gerende som indblæsningsapparat, fig. 3 viser apparatet med en noget opsvinget ventilationsdel, fig. 4 viser apparatet i vandret snit med åben ventilationsdel, og 20 fig. 5 viser apparatet set fra den indre side.The invention also enables a simple way to obtain humidification during wintertime and cooling in summer time, as explained in more detail below. The invention will now be described in more detail with reference to the drawing, in which: FIG. 1 is a vertical sectional view showing an advantageous embodiment of an apparatus according to the invention acting as a blow-out apparatus; FIG. 2 shows the same as FIG. 1 with the apparatus acting as a blower; FIG. 3 shows the apparatus with a somewhat pivoted ventilation part; FIG. 4 shows the apparatus in horizontal section with open ventilation section, and FIG. 5 shows the apparatus from the inside.
Ifølge fig. 1 på tegningen er et ventilationsapparat monteret i en udluftningsåbning 3, som er udført i væggen i en bygning 2 for et udluftningsvindue til et stue-rum 1. Ventilationsapparatet omfatter en ramme 4, som 25 er fastgjort i nævnte åbning, samt en filterdel 5 og en ventilationsdel 6. Filterdelen er fastgjort i rammen for at dække åbningen med undtagelse af dens nedre kant, og foran filterdelen er anbragt et ydre spjsldværk 7. Ventilationsdelen er ved hjælp af hængsler 8 lejretAccording to FIG. 1 of the drawing, a ventilation apparatus is mounted in a vent opening 3 which is formed in the wall of a building 2 for a vent window to a living room 1. The ventilation apparatus comprises a frame 4 which is fixed in said opening, as well as a filter part 5 and a ventilation member 6. The filter member is secured in the frame to cover the opening with the exception of its lower edge, and in front of the filter member is placed an outer firework 7. The ventilation member is mounted by means of hinges 8

5 som en svingbar enhed i den murede ramme, og delen dækker i fastsvinget tilstand helt udluftningsåbningen.5 as a pivotal unit in the walled frame, and the part completely covers the vent opening in the pivoted position.
Under filterdelen er et skiftespjæld 10 svingeligt lejret ved en udblæsningsåbning 9. Ventilationsdelen om-5 fatter en af oven på hinanden beliggende pladeceller 11, 12, 13 bestående varmeakkumulator 14, en ventilator 15 og en luftfordelingskanal. Skiverne i varmeak-kumulatorens nederste celle er bøjet for at danne de mod skiftespjældet rettede udluftningsmundstykker 11a.Below the filter portion, a shift damper 10 is pivotally mounted at a blowout opening 9. The ventilation portion comprises a superimposed plate accumulator 11, 12, 13 consisting of heat accumulator 14, a fan 15 and an air distribution duct. The discs in the lower cell of the heat-accumulator are bent to form the vent nozzles 11a directed toward the shift damper.
10 Luftfordelingskanalen omfatter en frontvæg 17 forsy net med i indbyrdes afstand beliggende gennemstrømnings-mundstykker 18.The air distribution duct comprises a front wall 17 provided with spaced-apart nozzles 18.
Fig. 1 viser apparatet fungerende som et udblæsnings-apparat. Ventilatoren suger stueluft A gennem mundstyk-15 ket 18 ind i luftfordelingskanalen og presser luften gennem varmeakkumulatorcellerne. Luften strømmer derefter gennem udblæsningsmundstykkerne 11a mod skiftespjældet. Skiftespjældet er excentrisk lejret eller balanceret på anden måde, således at det, når appara-20 tet er stillestående, automatisk svinges til den i fig.FIG. 1 shows the apparatus acting as a blow-out apparatus. The fan draws room air A through the nozzle 18 into the air distribution duct and presses the air through the heat accumulator cells. The air then flows through the exhaust nozzles 11a toward the shift damper. The shift damper is eccentrically mounted or otherwise balanced so that when the device is stationary, it is automatically pivoted to the one shown in FIG.
2 viste stilling, hvor spjældet lukker udblæsningsåbningen 9. Luftstrålerne, som strømmer med stor hastighed ud fra mundstykkerne 11a, rammer det i stillingen i fig. 2 beliggende skiftespjæld og svinger det til 25 den i fig. 1 viste stilling. Herved åbner skiftespjæl det udblæsningsåbningen 9 og tilslutter en til filteret ledende strømningsspalte 19. Ved at luften blæses med stor hastighed ud fra udblæsningsåbningen 9 kan udblæsningsluften godt frigøres fra ydervæggen, og her-30 ved undgås en tilsmudsning af ydervæggen, fugtskader osv. samt såkaldt kortslutning, dvs. udblæsningsluften hindres i at komme direkte tilbage til indstrømningsåbningen.2, where the damper closes the outlet opening 9. The air jets, which flow at great speed from the nozzles 11a, hit it in the position in fig. 2, and it swings it to the position shown in FIG. 1. Hereby, the damper opens the exhaust opening 9 and closes a flow gap 19. Conducting the air at a high velocity from the exhaust opening 9, the exhaust air can be easily released from the outer wall, thereby avoiding soiling of the outer wall, dampening and so on. , ie the exhaust air is prevented from returning directly to the inflow opening.

Fig. 2 viser apparatet fungerende som et indblæsnings-apparat. Ventilatoren roterer nu i modsat retning og suger yderluft B gennem spjældsystemet og filteret og videre gennem strømningsspalten 19 ind i varmeakkumula-5 toren. Derfra presser ventilatoren yderluften ind i luftfordelingskanalen og videre gennem mundstykkerne 18 i stuerummet. Imidlertid hersker der inde i apparatet et undertryk sammenlignet med yderluften, hvilket undertryk er lige så stort som tryktabet over spjældsystemet 10 og filteret, og når luften strømmer gennem disse, tætnes pladen godt imod sin ramme og lukker udblæsningsåbningen 9 tæt. På denne måde sikres, at ingen ufiltreret luft kommer ind i apparatet.FIG. 2 shows the apparatus acting as a blow-in apparatus. The fan now rotates in the opposite direction and sucks outer air B through the damper system and filter and further through the flow gap 19 into the heat accumulator. From there, the fan presses the outer air into the air distribution duct and further through the nozzles 18 into the living room. However, inside the apparatus there is a negative pressure compared to the outer air, which negative pressure is equal to the pressure loss over the damper system 10 and the filter, and as the air flows through them, the plate seals well against its frame and closes the exhaust opening 9. This ensures that no unfiltered air enters the device.
Udblæsningsåbningen 9 er således udformet, at luftens 15 udstrømningshastighed er så stor, at' tryktabet ved udblæs ningen er næsten lige så stort som filtrets og spjældsystemets tryktab i indblæsningstrinnet. På denne måde kan udblæsning- og indblæsningsluftmængderne holdes lige store, hvis det ønskes. Det er også muligt at ændre 20 udblæsningshastigheden og det således fremkomne tryktab, hvorved et ønsket forhold mellem udblæsnings- og indblæs-ningsstrømmene endog opnås.The outlet opening 9 is designed such that the outflow velocity of the air 15 is so great that the pressure drop during the blowout is almost as great as the pressure loss of the filter and the damper system in the supply stage. In this way, the exhaust and supply air volumes can be kept equal if desired. It is also possible to change the blowout speed and the pressure loss thus obtained, thereby even obtaining a desired ratio between the blowing and blowing flows.
Ifølge fig. 3 og 4 kan varmeakkumulatoren 14 svinges bort fra den fra yderluftsåbningen tilsluttede funktions-25 stilling, således at man på sædvanlig måde kan ventilere gennem åbningen. Herved kommer yderluften ind i rummet i filtreret tilstand, medens filteret forbliver tilbage i åbningen. Da akkumulatoren er svinget ud, er det let at rengøre og vedligeholde apparatdelene.According to FIG. 3 and 4, the heat accumulator 14 can be pivoted away from the operating position connected to the outer air opening, so that it can be vented through the opening in the usual way. In this way, the outer air enters the room in a filtered state, while the filter remains in the opening. As the accumulator is swiveled out, it is easy to clean and maintain the appliance parts.
30 Ifølge fig. 1 og 5 er luftfordelingskanalen placeret oven over et vindue 20 og dets forvæg 17 er udformet som et gardinbræt. En gardinskinne 21 er fastgjort i kanalens undervæg. Gardinbrættet er udført aftageligt,30 According to FIG. 1 and 5, the air distribution duct is located above a window 20 and its front wall 17 is designed as a curtain board. A curtain rail 21 is secured to the lower wall of the duct. The curtain board is removable,

7 f.eks. ved hjælp af hægter eller lignende fastgørelses-organer, således at hele kanalen let kan rengøres. Gennem mundstykkerne 18 i gardinbrættet kan luften fordeles over et stort område af rummet med en ringe indblæsnings-5 hastighed.7 e.g. by means of hooks or similar fasteners so that the entire duct can be easily cleaned. Through the nozzles 18 of the curtain board, the air can be distributed over a large area of the room at a low blow-in speed.
Det har vist sig, at en på denne måde udformet luftfordelingskanal har den fordel, at den forøger varmegenvin-dingens virkningsgrad, mens hele kanalen og gardinbrættet med stor overflade fungerer som varmegenindvindings-10 organ.It has been found that an air distribution duct formed in this way has the advantage of increasing the efficiency of the heat recovery, while the entire duct and the large surface curtain board act as a heat recovery means.
Når varmeakkumulatoren opdeles i mindst to eller flere dele 11, 12 og 13, kan varmestrømmen inde i varmevekslerens plader brydes og varmegenvindingsgraden enten forbedres eller pladernes længde i luftens strømningsretning 15 forkortes, når en bestemt varmegenvindingsgrad tilstræbes.When the heat accumulator is divided into at least two or more parts 11, 12 and 13, the heat flow within the heat exchanger plates can be interrupted and the heat recovery rate either improved or the length of the plates in the air flow direction 15 shortened when a certain degree of heat recovery is sought.
Herved opnås et apparat, som fylder mindre eller er billigere end kendte konstruktioner. Da apparatet ifølge opfindelsen desuden er forsynet med et filter, kan den interne afstand mellem pladerne mindskes uden risiko 20 for tilstopning. På denne måde kan man med en ca. 600 mm lang varmeakkumulator opnå over 80% varmevirkningsgrad, hvilket gør det muligt at anbringe apparatet i udluftningsvinduet. Håndteringen, vedligeholdelsen og rengøringen af korte, af tynd plade fremstillede akku-25 mulatorer er let.This results in an apparatus which is smaller or cheaper than known constructions. Furthermore, since the apparatus according to the invention is provided with a filter, the internal distance between the plates can be reduced without the risk of clogging. In this way, with a approx. 600 mm long heat accumulator achieves more than 80% heat efficiency, which makes it possible to place the appliance in the vent window. The handling, maintenance and cleaning of short thin-plate accumulators is easy.
Opfindelsen omfatter også en enkelt fremgangsmåde til at opnå befugtning om vinteren og afkøling om sommeren.The invention also encompasses a single method of obtaining wetting in winter and cooling in summer.
Når der i luftfordelingskanalen 9 eller rummet mellem ventilatoren 15 og varmeakkumulatorcellen 13 placeres 30 et enkelt befugtningsmundstykke 22, kan befugtningen om vinteren opnås således, at en ventil førende til befugtningsmundstykket åbnes i indblæsningstrinnets begyndelse, hvorved mundstykket sprøjter vand, som del-When a single wetting nozzle 22 is placed in the air distribution duct 9 or the space between the fan 15 and the heat accumulator cell 13, the humidification in winter can be achieved such that a valve leading to the humidifier nozzle is opened at the beginning of the blow-in stage, whereby the nozzle sprays water which divides.

8 vis fordamper i luften, delvis løber ned i varmeakkumu-latorcellerne 13 og 12. Ventilen holdes åben så længe, at den vandmængde, som kraves for at forøge luftens fugtighed til et ønsket niveau, kan måles i cellerne 5 13 og 12. Selv efter ventilen er lukket, fordamper vand fra cellernes våde overflader i luften og fugter luften yderligere. Eftersom pladernes mellemrum i cellerne er små og der findes rigeligt med pladeoverflader, er befugtningen meget effektiv. Varmegenvindingscellerne 10 fungerer således samtidig som befugtningsceller, og man behøver ikke nogen i sædvanlige anordninger krævede separate befugtningsceller eller -kamre.8, evaporate in the air, partly run down into the heat accumulator cells 13 and 12. The valve is kept open so long that the amount of water required to increase the humidity of the air to a desired level can be measured in cells 5 13 and 12. Even after the valve is closed, evaporating water from the wet surfaces of the cells in the air and further moisturizing the air. Since the plates' spaces in the cells are small and there are plenty of plate surfaces, wetting is very effective. Thus, the heat recovery cells 10 function simultaneously as wetting cells, and no separate wetting cells or chambers are required in conventional devices.
Varmegenvindingsceller 11, 12 og 13 fungerer også som fugtoptagende anordninger. Dette beror på, at vanddamp 15 i luften kondenseres til vand, hovedsagelig på optag ningscellernes 11 og 12 overflader, når den fugtige inderluft under udblæsningstrinnet nedkøles ved passagen gennem cellerne.Heat recovery cells 11, 12 and 13 also function as moisture absorbing devices. This is because water vapor 15 in the air is condensed into water, mainly on the surfaces of the receiving cells 11 and 12, as the humid inner air during the blow-out stage is cooled by passage through the cells.
Under indblæsningstrinnet fordampes vandet igen til 20 den tørre indblasningsluft.During the blow-in step, the water is again evaporated to dry blow-in air.
Behovet for tillægsbefugtning er i et sådant apparat meget ringe. For en så ringe befugtning er apparatoverfladernes fordampningsevne tilstrækkelig, og små vandmængder forårsager ingen korrosions-, tilstopnings-25 eller lignende problemer som i kendte apparater. Selv følgelig er også andre befugtningsmetoder, f.eks. damp-befugtning, mulige.The need for additional wetting in such an apparatus is very low. For such poor wetting, the evaporative ability of the device surfaces is sufficient, and small amounts of water do not cause any corrosion, clogging or similar problems as in prior art devices. Accordingly, other wetting methods, e.g. steam-wetting, possible.
Når behovet for befugtning er ringe, bliver den ved indvirkning af den periodevis forekommende befugtning 30 ifølge opfindelsen forårsagede variation af luftfugtig heden så ringe, at den ikke har nogen praktisk negativ virkning. Ligeledes bliver den af befugtningen forårsa-When the need for wetting is low, the variation of the humidity of the invention caused by the periodic wetting 30 according to the invention becomes so low that it has no practical negative effect. Likewise, it is caused by the wetting spring.

9 gede sænkning af indblæsningsluftens temperatur så ringe, at luften ikke engang nødvendigvis behøver opvarmes.9 lowering the supply air temperature so low that the air does not even need to be heated.
Når temperatur- og fugtvariationerne er små og appara-tets driftsperiode er kort, kan der i stedet for en 5 relativ regulering anvendes en on-off-indstilling og f.eks. i stedet for regulering af temperatur og fugtighed, kan den tid reguleres, under hvilken befugtningen, opvarmningen med mere er i gang, uden at fugtigheden eller temperaturen i rummet, som skal ventileres, skifter 10 mærkbart. Reguleringen kan enten ske således, at befugt-ningen, opvarmningen eller lignende er i gang en bestemt del af driftsperioden, eller således, at den ønskede luftbehandling er i gang i hele driftsperioden, men kun under en del af driftsperioderne, eller ved at sam-15 mensætte begge fremgangsmådetrin. Sammenlignet med en relativ regulering forenkles anordningerne væsentligt og prisen for et helt reguleringssystem er kun en del af prisen for de traditionelle systemer. Anordningens driftssikkerhed forbedres endog væsentligt.When the temperature and humidity variations are small and the device operating period is short, an on-off setting can be used instead of a relative control and e.g. instead of regulating temperature and humidity, the time can be regulated during which the humidification, heating and more are started, without the humidity or temperature of the room to be ventilated changing noticeably. The control can either be done so that the humidification, heating or the like is in operation for a certain part of the operating period, or so that the desired air treatment is in operation throughout the operating period, but only during part of the operating periods, or 15 to complete both process steps. Compared to relative regulation, the devices are significantly simplified and the cost of an entire control system is only part of the cost of the traditional systems. The device's reliability is even significantly improved.
20 I detaljer kan apparatet ifølge opfindelsen variere.In detail, the apparatus according to the invention may vary.
Således kan skiftespjældet forsynes med en drivanordning, som svinger det til forskellige stillinger i afhængighed af apparatets funktion. Skiftespjældet kan også monteres til at forskydes sammen med den sving-25 bare ventilationsdel. I stedet for en svingbar konstruk tion er det også muligt at gøre apparatets bevægelige del på anden måde forskydelig bort fra yderluftsåbningen, f.eks. bevægelig langs skinner. I stedet for akkumulatoren 14 er det også muligt at gøre en anden del 30 af apparatet forskydelig.Thus, the shift damper can be provided with a drive device which pivots it to different positions depending on the function of the apparatus. The shift damper may also be mounted to be displaced together with the pivotable ventilation member. Instead of a pivotal structure, it is also possible to make the moving part of the apparatus otherwise displaceable away from the outer air opening, e.g. movable along rails. Instead of the accumulator 14, it is also possible to make another part 30 of the apparatus slidable.
