Huonekohtainen ilmastointiyksikkoRoom air conditioning unit

Keksinto kohdistuu huonekohtaiseen ilmastointiyk-sikkoon, joka toimii tavanomaisen keskitetyn ilmastointi-5 laitteen tapaan, kåsittåen tulo- ja poistoilmapuhaltimet, låmmitysyksikon, låmmonsiirtimen tulo- ja poistoilmalle, ilman suodattimen sekå haihdutinperiaatteella toimivan jååhdyttimen.The invention relates to a room-specific air-conditioning unit which operates in the same way as a conventional central air-conditioning unit 5, comprising supply and exhaust air fans, a heating unit, a heat exchanger for supply and exhaust air, an air filter and an evaporator-based radiator.

Ilmastointilaitteet ovat yleenså olleet keskitet-10 tyjå yksikoitå, joista on kanavajårjestelyillå johdettu tulo- ja poistoilma huonetiloihin. Tållaisia laitteita on lukuisia markkinoilla.Air conditioners have generally been centralized units, from which supply and exhaust air has been led to the rooms through duct arrangements. There are numerous such devices on the market.

Ilmastointilaitteissa on tavanomaisesti eri toi-minnoille omat osansa. Niinpå tållainen laite koostuu 15 erillisistå tulo- ja poistoilmapuhaltimista, lammontal-teenottoyksikostå, suodatinyksikostå, lammityspatterista, jååhdytinyksikostå sekå ilmankostutinyksikostå.Air conditioners usually have their own parts for different functions. Thus, such a device consists of 15 separate supply and exhaust air fans, a lammontal intake unit, a filter unit, a heating coil, a chiller unit and a humidifier unit.

Luonnollisesti on kåytosså ollut myos pelkkiå tulo- ja poistoilmapuhaltimia, joilla on hoidettu huoneti-20 lan ilmanvaihto. Myoskin huonetilaan sijoitetut erilliset suodatin- ja ilmanpuhdistusyksikot ovat tunnettuja. Nåiden toiminta perustuu eri menetelmiin esim. mekaaniseen- ja såhkosuodatukseen.Of course, only supply and exhaust air fans with room-20 ventilation have also been used. Separate filter and air cleaning units located in the room are also known. Their operation is based on various methods, eg mechanical and electrofiltration.

Myos huonetilaan sijoitetut erilliset ilmankostu-25 tuslaitteet ovat yleisesti tunnettuja. Nåmå laitteet toimi-vat usein myos jonkin asteisina puhdistimina. Edellå maini-tuille huonekohtaisille laitteille on yleenså yhteistå se, ettå niisså kierråtetåån huoneilmaa. Erilliset ilroan jååh-dytyslaitteet ovat myos varsin yleisesti kåytosså. Tållai-30 sissa laitteissa kåytetåån yleenså låmpopumppua, jolla jååhdytysnesteen avulla siirretåån låmpoenergiaa huonetilan ulkopuolelle. Myos sellaiset laitteet, joissa ilman avulla siirretåån låmpo ulkoilmaan ovat tunnettuja.Separate humidifiers located in the room are also well known. These devices often also act as purifiers of some degree. The room-specific devices mentioned above generally have in common that they recirculate room air. Separate ilro cooling units are also quite commonly used. Such devices generally use a heat pump to transfer heat energy to the outside of the room by means of a coolant. Devices in which the heat is transferred to the outside air by means of air are also known.

Nykyinen tekniikan taso on varsin kirjava. Ilmas-35 tointijårjestelmå koostuu usein erillisistå laitteista, 2 91916 joista osa voi olla keskitettyjå ja osa huonekohtaisia. Niinpå låmmitys saatetaan hoitaa erillisillå pattereilla joko såhkoverkkoon tai vesikeskuslåmmitykseen kytkettyinå. Ilmanvaihto voi olla keskitetty. Tåmån lisåksi huonetilaan 5 voidaan sijoittaa erilliset suodatus-, kostutus- ja jååh-dytyslaitteet.The current state of the art is quite variegated. The air-35 control system often consists of separate devices, 2,91916 of which may be centralized and some room-specific. Thus, the heating may be handled by separate radiators, either connected to the mains or to the central heating. Ventilation can be centralized. In addition, separate filtration, humidification and cooling devices can be placed in the room space 5.

Edellå esitettyyn tilanteeseen on osaltaan johta-nut se tosiasia, ettå suurin osa rakennuksista on rakennet-tu aikana, jolloin ilmastointitekniikan taso on ollut huo-10 mattavasti matalampi kuin tånå påivånå. Lisåksi on vaati-mustaso huoneilman suhteen huomattavasti noussut.The situation presented above has been partly due to the fact that most of the buildings were built at a time when the level of air conditioning technology has been considerably lower than today. In addition, the required black level for room air has risen considerably.

Varsinkin korjausrakentamisessa on tåydellisen keskitetyn ilmastointijårjestelmån luominen kallista ja hankalaa, joskus jopa mahdotonta rakenteiden ja tilojen 15 puutteen vuoksi. Tållaisen ilmastointijårjestelmån teke-minen vaatii usein niin paljon apurakenteita, ettå ilmas-toinnin osuus rakentamisesta on vain murto-osa.Especially in renovation construction, the creation of a complete centralized air conditioning system is expensive and cumbersome, sometimes even impossible due to the lack of structures and facilities. Making such an air conditioning system often requires so many auxiliary structures that air conditioning accounts for only a fraction of construction.

Erillisjårjestelmåt tulevat usein kalliiksi myos hankintahinnaltaan ja varsinkin energiankulutuksen suhteen. 20 Keksinnon mukaiselle laitteelle on tunnusomaista se, mitå on esitetty jåjempånå seuraavien patettivaatimus-ten tunnusmerkkiosassa.Stand-alone systems also often become expensive in terms of purchase price and especially in terms of energy consumption. The device according to the invention is characterized by what is set out below in the characterizing part of the following claims.

Keksinnon tårkeimpånå etuna voidaan pitåå sitå, ettå laite voidaan asentaa huonetilaan tekemåttå rakentei-25 siin mitåån muutoksia tai korkeintaan tekemållå poisto- ja tuloilmakanavat ulkoseinåån. Kanavistoihin kerååntyvån lian ja polyn vaikutusta terveyteen on viime aikoina tutkittu. Puhdistettavuuteen tullaan kiinnittåmåån enemmån huomiota palo- ja terveysriskien vuoksi.The main advantage of the invention can be considered that the device can be installed in the room without making any changes to the structures or at most by making the exhaust and supply air ducts in the outer wall. The effect of dirt and pollen accumulating in sewer systems on health has recently been studied. More attention will be paid to cleanability due to fire and health risks.

30 Keksinnon mukaisen laitteen etuna on sen muunnel- tavuus. Osa toiminnoista voidaan jåttåå pois ja lisåtå mah-dollisesti myohemmin. Laite voidaan varustaa manuaalisella ohjauksella tai automatisoida tåysin, jolloin se sisåltåå tarvittavat logiikat sekå esim. kosteus- ja låmpotila-35 anturit.The advantage of the device according to the invention is its versatility. Some functions can be omitted and possibly added later. The device can be equipped with manual control or fully automated, in which case it contains the necessary logics as well as, for example, humidity and temperature sensors.

Jos mainitut kana-vat johdetaan suoraan seinån låpi, vastaa niitå numerot 25 5 ja 24. Esilåmmonsiirrin 3 voidaan sijoittaa tuuletusluukun tai vastaavan kehyksiin 26. Takaiskuventtiilien 27 ja 28 avulla ohjataan virtaus huonetilaan tuuletuksen ollessa pois pååltå. Alasåiliostå 19 vesi pumpataan pumpulla 29 putkea 30 myoten pakkaan 10. Venttiileiden 31 ja 32 avulla 10 vesi ohjataan joko kostutukseen tai jååhdytykseen.In Fig. 3, the supply air fan 20 and the exhaust air fan 21 are shown. If said ducts are led directly through the wall, they correspond to the numbers 25 5 and 24. The preheater 3 can be placed in the frames 26 of the ventilation hatch or the like. The non-return valves 27 and 28 direct the flow to the room with the ventilation off. From the lower tank 19, the water is pumped by the pump 29 to the pipe 10. The valves 31 and 32 are used to direct the water to either humidification or cooling.

Kuviossa 4 on esitetty rakenne, joka koostuu ohuista esim. alumiinilevyistå 33 ja erittåin huokoisista levyistå 34. Pakan 10 kanavissa 12, 13 ja 14 sekå påållå joka toinen våli on suljettu 35.

Every other space is provided with sleeves 36 which prevent water from leaking. in the election. The sleeves 36 are arranged so that water flows from one pipe to the air inlet 3a and from the other to the outlet.

20 Huonekohtainen ilmastointilaite toimii jååhdytti- menå seuraavaan tapaan. Molemmat puhaltimet 20 ja 21 ovat påållå. Pakan 10 poistoilmasoliin johdetaan vettå, joka ilman virratessa haihtuessaan luovuttaa låmpoå. Ulkoa tuleva ilma suodattuu ja jååhtyy tulosolissa. Saavutetta-25 vissa oleva jååhdytys on riippuvainen ilman suhteellisesta kosteudesta. Prosessi noudattaa luonnollisesti Mollier-diagrammia.20 The room air conditioner acts as a radiator as follows. Both fans 20 and 21 are on. Water is introduced into the exhaust air sol of the deck 10, which dissipates heat as the air flows as it evaporates. The outside air is filtered and cooled in the inlet. The cooling in achievement 25 depends on the relative humidity of the air. The process naturally follows the Mollier diagram.

Kun laitetta kåytetåån låmmitykseen, puhallin 21 on påållå, låppå 27 aukeaa ja låppa 28 sulkeutuu eståen 30 ilman suoran ulosvirtauksen. Låmmityksesså poistoilmapu- hallin 21 painaa ilman pakan 10 tuloilmasoliin, jotka ovat auki pakan 10 pååltå ja ilma virtaa låmmitysvastusten 16 låpi tilasta 15 ritilån 9 kautta huonetilaan. Solissa oleva materiaali 34 suodattaa luonnollisesti kierråtettåvån 35 huoneilman.When the device is used for heating, the fan 21 is on, the flap 27 opens and the flap 28 closes, preventing 30 from direct air outflow. In heating, the exhaust air blower 21 presses air into the supply air soles of the stack 10, which are open on top of the stack 10, and air flows through the heating resistors 16 from the space 15 through the grille 9 to the room space. The material 34 in the sol naturally filters the recirculated room air 35.

Silloin kun huoneilman kosteus on liian alhainen, johdetaan tulosoliin vettå jaksottaisesti ja laite toimii tålloin ilmankostuttimena.When the humidity in the room air is too low, water is introduced to the inlet cells periodically and the device then acts as a humidifier.

Kun laitetta halutaan kåyttåå ilmanvaihtoon, 5 kytketåån molemmat puhaltimet 20, 21 påålle. Pakka 10 toimii tålloin låmmontalteenottolaitteena. Myos ilmanvaih-don, låmmityksen ja kostutuksen yhteiskåytto on mahdol-lista.When it is desired to use the device for ventilation, both fans 20, 21 are switched on. The pack 10 then acts as a heat recovery device. The combined use of ventilation, heating and humidification is also possible.

Jos pakan 10 solat tukkeutuvat vaikeiden olosuh-10 teiden, esim. erittåin suuren polypitoisuuden vuoksi, voi-daan pakka 10 huuhdella avaamalla venttiilit 31 ja 32 tåysin ja kåynniståmållå pumppu 29.If the slots in the pack 10 become clogged due to difficult conditions, e.g. a very high poly content, the pack 10 can be flushed by opening the valves 31 and 32 completely and starting the pump 29.

On selvåå, ettå keksinnon mukainen laite voidaan varustaa joko manuaalisella ohjauksella tai automatisoida 15 tåysin, jolloin laitteeseen tarvitaan anturit låmpotilan, kosteuden jne. mittausta vårten. Luonnollisesti pakka 10 voidaan sijoittaa tåysin toiseen asentoon ja kanavoinnit tehdå pakan 10 sisåån seuraavien patenttivaatimusten måå-rittelemån keksinnollisen ajatuksen puitteissa.It is clear that the device according to the invention can be equipped either with manual control or fully automated, in which case the device requires sensors for measuring temperature, humidity, etc. Of course, the package 10 can be placed in a completely different position and the channeling can be done inside the package 10 within the scope of the inventive idea defined by the following claims.
