Ilmanjakolaite ja ilmanjakolaitteen sååtomenetelmå Luftfordelningsanordning och forfarande for reglering av en luftfordelningsanordning 5Air distribution device and air distribution device adjustment method Air handling unit and control unit for air handling unit 5
Keksinnon kohteena on ilmanjakolaite ja menetelmå ilmavirtauksen sååtåmiseksi.The invention relates to an air distribution device and a method for controlling the air flow.
Ilmanjakolaitteen kaytolle on edullista, ettå laite pystytåån mukauttamaan tilan tarpeisiin ja laitteen aiheuttamaa virtauskenttåå pystytåån muuntelemaan. Ilmanjakolait-10 teen valintaa rajoittaa useasti heittokuvion soveltumattomuus tilaan. Heittokuvio voi olla joko liian pitkå tai liian lyhyt. Jos laitteita on asetettava useita vierekkain tai laitteita on asetettava låhelle virtausesteitå, olisi edullista, ettå osa laitteen ilmanjakopinta-alasta voitaisiin sulkea.It is advantageous for the use of an air distribution device that the device can be adapted to the needs of the space and that the flow field caused by the device can be modified. The choice of air divider-10 tea is often limited by the unsuitability of the throw pattern for the space. The throw pattern can be either too long or too short. If several devices have to be placed side by side or devices have to be placed close to flow barriers, it would be advantageous for part of the air distribution area of the device to be closed.
15 Keksinnosså on pystytty loytåmåån ratkaisu edellå mainittuun ongelmaan. Keksinnos-så kåytetåån ilmanjakolaitteen ilmavirtauksen sisåånpuhalluskuvion sååtolaitteena levyå, joka kåsittåå jakeita, jotka on taivutettavissa haluttuun virtauksen toteuttavaan asen toon. Jakeita on useita ja ne on sijoitettu ympyrålevyyn sektoreittain, jolloin haluttaessa sååtåå tiettyyn suuntaan ilmanjakolaitteesta låhtevåå virtausta, kåånnetåån 20 sååtolevyn mainitun suunnan jakeet halutun virtauksen toteuttavaan asentoon.The invention makes it possible to find a solution to the above-mentioned problem. In the invention, a plate comprising fractions which can be bent to the desired position implementing the flow is used as the air flow supply pattern control device of the air distributor. There are several fractions and they are arranged in a circular plate by sector, whereby if it is desired to adjust the flow from the air distributor in a certain direction, the fractions of said direction of the 20 baffles are turned to the position implementing the desired flow.
Keksinnon mukaisesti voidaan levyn avulla muuttaa ilmanjakolaitteesta låhtevåå ilmavirtausta. Taivuttamalla jakeita tulovirtaukseen nåhden viistosti voidaan virtausta lisåksi poikkeuttaa siten, ettå låhtovirtaus ilmanjakolaitteesta on viistosti laitteen 25 reunaan nåhden. Nåin olien laitteella voidaan aikaansaada pyorivå virtauskenttå ilmanjakolaitteen ympårille.According to the invention, the air flow leaving the air distributor can be changed by means of the plate. By bending the fractions obliquely to the inlet flow, the flow can additionally be deflected so that the outlet flow from the air distributor is oblique to the edge of the device 25. In this way, the device can provide a rotating flow field around the air distributor.
Sååtolevyn taivutettujen jakeiden lukumååråå vaihtelemalla voidaan lisåksi sååtåå virtauksen muuntelun tarkkuutta. Materiaalina kåytetåån jåykkåå metallilevyå, joka 30 pitåå muotonsa taivutuksen jålkeen. Taivutus tehdåån kåsin asennuspaikalla tai jo tehtaalla ilmanjakolaitteen valmistusvaiheessa. Sååtolevy on tehty edullisesti yhdestå levystå meiståmållå tai koottu useasta osasta.By varying the number of bent fractions on the control plate, the accuracy of the flow variation can also be adjusted. The material used is a rigid metal plate which retains its shape after bending. Bending is done manually at the installation site or already at the factory during the manufacturing process of the air distributor. The control plate is preferably made of one plate by stamping or assembled from several parts.

Keksinnon mukaiselle ilmanjakolaitteelle on pååasiallisesti tunnusomaista, ettå kunkin jakeen molemmilla reunoilla on rako, joka kulkee yhtenåisen levyn reunoilta levyn keskikohtaa kohti, jolloin saåtolevyn jakeet ovat kukin taivutettavissa jakeen ulko-reunanpuoleisesta påådyståån ylospåin kohti tuloilmakammion ylåosaa, jolloin 5 ilmavirtaus on saådettavissa halutussa sektorissa kunkin jakeen ollessa itsenåisesti taivutettavissa yhtenåisen levyn levytasoon nåhden.The air distribution device according to the invention is mainly characterized in that both edges of each fraction have a gap running from the edges of a uniform plate towards the center of the plate, the fractions of the inlet plate being each bendable at independently bendable relative to the plate plane of a uniform plate.
Keksinnon mukaiselle ilmanjakolaitteen sååtomenetelmålle on pååasiallisesti tunnusomaista, etta menetelmåsså såådetåån ilmavirtaus halutuksi kussakin sektorissa 10 taivuttamalla sektorin jaetta siten, etta jakeen ulkoreunaa nostetaan kohti tuloilmakammion ylåosaa jakeen taivutuksen tapahtuessa jakeen toisen påådyn suhteen, jolloin kutakin jaetta taivuttamalla on ilmavirtaus såådettåvissa halutuksi kussakin sektorissa, ja jolloin jaetta tuloilmakammion ylåosia kohti taivuttamalla lisåtåån ilmavirtauksen kuristusta jakeen kohdalla olevassa sektorissa.The air distribution device according to the invention according to the invention is mainly characterized in that the method adjusts the desired air flow in each sector 10 by bending the sector fraction so that towards the tops of the supply air chamber by bending to increase the airflow restriction in the sector at the fraction.
