Description

15 20 25 30 523 294 Uppfinningen beskrivs i det íöliande under hänvisning till några i figllreyna på bifogade ritningar visade en fórdelaktig utforingsforrn av uppfinningen. Avsikten är dock inte att begränsa uppfinningen enbart till denna. The invention is described in the following with reference to some embodiments of the invention which show an advantageous embodiment of the invention. However, the intention is not to limit the invention only to this.
Figur IA visar en fördelaktig utföringsform av regleranordningen enligt uppfin- ningen, varvid regleranordningen är belägen i en sidokammare Bl.Figure 1A shows an advantageous embodiment of the control device according to the invention, wherein the control device is located in a side chamber B1.
Figur IB visar axonometriskt en fórskjutningsmekanism i anslutning till regleran- ordningen enligt figur IA.Figure IB shows axonometrically a displacement mechanism in connection with the control device according to Figure 1A.
Figur IA visar en vy av en inloppsluftanordning 10. En gavelvägg 10d är av fram- ställningsmässiga skäl delvis bortskuren för visande av den inre konstruktionen.Figure 1A shows a view of an inlet air device 10. A gable wall 10d is, for manufacturing reasons, partly cut away to show the inner construction.
Två gavelväggar 10d och två sidoskivor 10b samt en inloppsluftkammare 11 be- gränsar sidokamrar Bl så att konstruktionen är sluten upptill och på sidorna, men öppen nedtill. Frisk luft leds genom en kanal in i inloppskammaren 1 l, från vilken luften leds vidare genom munstycken 12al,I2a2... in i sido- eller blandningskam- rarna Bl på båda sidor om en vertikal mittaxel Yl av anordningen. Inloppsluftan- ordningen 10 omfattar en värmeväxlare 14 i mittområdet av anordningen mellan Iuftstyrningsdelar 13, som begränsar sidokamrarna Bl, och under inloppsluft- kammaren I1. Cirkulationsluft L; från ett rum har en strömningsväg El genom värmeväxlaren 14 till sidokamrama Bl. Ifrågavarande luftströmning L; eller se- kundärluftströmning åstadkoms av primärluftströmningen genom munstyckena 12al,I2a2... i inloppskammaren 11, I sidokamrama Bl förenas luftströmningarna Ll+L2 och den förenade luftströmningen bringas att strömma åt sidan styrda av luftstyrningsdelama 13 och sidoskivoma 10b av inloppsluftanordningen.Two end walls 10d and two side panels 10b and an inlet air chamber 11 delimit side chambers B1 so that the structure is closed at the top and on the sides, but open at the bottom. Fresh air is led through a duct into the inlet chamber 11, from which the air is passed further through nozzles 12a1, I2a2 ... into the side or mixing chambers B1 on both sides of a vertical central axis Y1 of the device. The inlet air device 10 comprises a heat exchanger 14 in the central area of the device between air control parts 13, which delimit the side chambers B1, and below the inlet air chamber I1. Circulating air L; from a room has a flow path E1 through the heat exchanger 14 to the side chambers B1. The air flow in question L; or secondary air flow is provided by the primary air flow through the nozzles 12a1, I2a2 ... in the inlet chamber 11, In the side chambers B1 the air flows L1 + L2 are combined and the combined air flow is caused to flow to the side controlled by the air guide parts 13 and the side plates 10b of the inlet air arrangement.
Inloppsluftanordningen 10 omfattar enligt uppfinningen en anordning 15 för re- glering av induktionsförhållandet. 10 523 294 I utforingsfonnen enligt figur 1A omfattar sidokammaren Bi en uppfinníngsenlig anordning 15 for reglering av induktionsförhållandet. Regleranordningen 15 be- står i utforingsformen enligt figuren av ett långsträckt reglerspjäll 17, som kan svängas i olika reglerlägen uppburet av en led 18 i kammaren Bl. Reglerspjället 17 bringas i önskade reglerlägen genom vridning av ett excentriskt element 19.According to the invention, the inlet air device 10 comprises a device 15 for regulating the induction ratio. In the embodiment according to Figure 1A, the side chamber Bi comprises a suitable device 15 for regulating the induction ratio. The control device 15 consists in the embodiment according to the figure of an elongate control damper 17, which can be pivoted in different control positions supported by a joint 18 in the chamber B1. The control damper 17 is brought into the desired control positions by turning an eccentric element 19.
Vardera sidokammaren B; omfattar en likadan, i figur 2A visad regleranordning 15 for induktionsförhållandet.Each side chamber B; comprises a similar control device 15, shown in Figure 2A, for the induction ratio.
Figur 1B visar en axonometrisk detaljvy av reglerspjället 17 i utfóringsforrnen enligt figur 1A. Cirkulationsluftströmningen L; kommer via hålskivan l6b1 eller motsvarande till värmeväxlaren 14 och går vidare in i sidokammaren BL Induk- tionsförhållandet regleras genom förskjutning av reglerspjället 17 i sido- och blandningskammaren B|.Figure 1B shows an axonometric detail view of the control damper 17 in the embodiments according to Figure 1A. Circulating air flow L; comes via the perforated plate 16b1 or equivalent to the heat exchanger 14 and goes further into the side chamber BL The induction ratio is regulated by displacing the control damper 17 in the side and mixing chamber B |.
