    SUMMARY OF THE INVENTION An object of the invention is to eliminate the above-mentioned problems.
    A further object of the invention is to be able to adjust or regulate the direction of an air flow out of the supply air device by regulating the size of an air flow rectifier in an air flow passage.
    A further object is to reduce the number of individual and moving parts and components which are active in the direction and regulation of an air flow out of the supply air device.
    An additional object is to reduce manufacturing time and manufacturing costs for the manufacture of supply air devices with adjustable air flow converters compared with known technology.
    The above-mentioned and other objects are achieved according to the invention in that the supply air device initially described has been given the features characterized by claim 1.
    Namely that the air flow converter is adjustably arranged in relation to the air flow passage between an inactive position and at least one active position where in the active position the air flow converter is physically more arranged inside the air flow passage than in the inactive position to deflect the outgoing air flow relative to the outgoing air flow in the idle mode.
    An advantage achieved with a device according to the invention is that an air flow out of supply air diffusers into the room can be regulated directly and distinctly compared with known technology. An additional advantage is that when regulating the air flow converter, no gaps between components in the air flow converter need occur due to by Lex. wear because the airflow rectifier does not include any moving parts that can wear against each other. A further advantage is that the air flow converter can be made of a material element or piece of material. When manufacturing the supply air diffuser, the manufacturing time and manufacturing cost can thus be kept low.
    This is because i.a. the airflow rectifier need not include components which need to be joined or interconnected.
    According to one embodiment, the active position of the air flow converter in the air flow passage is variable. An effect of this is that it is thus possible to regulate, set, how large a part of the outgoing air flow that is desired is angled away from the outlet of the supply air device.
    According to a further embodiment, the air flow rectifier is controllably arranged in relation to the air flow passage via recesses to the air flow passage. The airflow rectifier includes air directional tabs. These air direction flaps are configured to be controllably arranged through said recesses. Furthermore, the air flow converter comprises an elongate element. The elongate member can act as a rigid beam member. Said air direction flaps are arranged to the elongate element and form a unit therewith. An effect of this is that the air flow rectifier comprising said air direction flaps and elongate elements can thus be manufactured from a material element, e.g. an elongate sheet metal plate where said air direction flaps can be formed by e.g. cutting, shearing, punching or other method of cutting through sheet metal. The material element or piece of material can be made of materials other than sheet metal, such as e.g. plastics, composites, etc.
    According to a further embodiment, said recesses are arranged in a wall element for the air flow passage. Said recesses may consist of a number of openings which are arranged at a distance relative to each other through the wall element. According to one embodiment, the openings, recessed, can be evenly distributed along the wall element. In the supply air device, the wall element is arranged along an outlet to the supply air device, through which outlet the air flow is led into the room. The wall element is configured to separate the air flow passage from a control space, which control space extends along the outlet and is formed by the wall element and a bottom part of the supply air device.
    According to a further embodiment, the elongate element of the air flow converter is arranged in the control space. Furthermore, the air direction flaps are arranged from the elongate element in the control space and through the respective opening in the wall element. An effect of this is that the elongate element is thus protected, or shielded, from the air flow passage, whereby no disturbing turbulence needs to arise in the air flow out of the outlet.
    According to a further embodiment, the air flow converter may comprise a control means for positioning the air flow converter in the air flow passage. Such a control means could enable a user to adjust, regulate, the position of the air flow rectifier in the supply air device.
    BRIEF DESCRIPTION OF THE DRAWINGS Preferred embodiments of the device according to the invention will now be described in more detail with reference to the accompanying schematic drawings, which only show the details necessary for understanding the invention.

    DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Fig. 1 shows a supply air diffuser 1 for device in a ceiling or in a load-bearing structure in a room.
    The supply air device 1 according to Fig. 1 is configured to receive a first air stream 2a, called supply air 2a. The supply air 2a is led into the supply air device 1 to be mixed therein with a second air stream 2b, called room air 2b. Room air 2b can e.g. by means of induction is sucked from the room into the supply air device 1. Said air streams 2a, 2b are mixed in the supply air device 1 and are then led out of the supply air device 1 as a third air stream 2c, called exhaust air 2c. The supply air device 1 is configured to discharge said exhaust air 2c to the room for mixing with existing room air in the room, and for the existing room air in the room to be continuously replaced during operation of the supply air device 1 with the supply air 2c from the supply air device 1. in the following text it is third airflow with flgur reference 2c synonymous with the term airflow with associated flgur reference 2c.
    Fig. 2 shows a supply air device 1 according to the invention for directing an air stream 2 into a room.
    The supply air device 1 comprises at least one air flow passage 3a, 3b with at least one air flow converter 4a, 4b arranged therein for controlling the air flow 2 from the supply air device 1 into the room. According to an embodiment of the invention, the supply air device 1 can be arranged with two air flow passages 3a, 3b. An air stream 2 can thus be led out of the supply air device 1 in two directions. According to a further embodiment, a supply air device can be arranged with three or four air flow passages. By having three air flow passages, the air flow from the supply air device can be led out in three directions, or from three sides, of the supply air device. Should four air flow passages be arranged in the supply air device, the air flow can be led out in all directions around the supply air device. This can be an advantage e.g. if the supply air diffuser is arranged centrally in a room and it is desired that air is to be led into the room at 360 degrees out from the supply air diffuser. In the supply air diffuser 1, one or more cooling batteries can be arranged, not shown in figure. Room air 2b which is sucked into the supply air device 1 passes through said cooling batteries pre-temperature influence.
    After passing through the cooling coils, the temperature-affected air is mixed with the supply air 2a to the supply air device. The temperature-affected, preferably colder, mixed air is then led out into the room as an air stream 2 from the supply air device 1. The air flow rectifier 4a, 4b is in the supply air device 1 controllably arranged in relation to the air flow passage 3a, 3b between an inactive position and at least an active position where in the active position the air flow converter 4a, 4b is physically more arranged inside the air flow passage 3a, 3b than in the inactive position. This is to in and / or from the air flow passage 3a, 3b angle the outgoing air stream 2 relative to the outgoing air stream 2 in the inactive position.
    According to the embodiment of the invention, at least one air flow rectifier 4a, 4b is arranged in connection with the respective air flow passage 3a, 3b. Fig. 2 on the left shows one air flow converter 4a in active position. On the other side in Fig. 2 on the right, the second air flow converter 4b is shown in an inactive position. In the active position the air flow converter 4a, 4b influences the air flow 2 by angling it when passing out of the supply air device 1. In the inactive position there is no, or substantially no, active influence to deflect the air flow when passing out of the supply air device 1.
    The active position of the air flow converter 4a, 4b is variable in the air flow passage 3a, 3b. This contributes to the position of the air flow converter 4a, 4b in the air flow passage 3a, 3b can be regulated in such a way that the direction of the outgoing air flow 2 from the supply air device 1 can be affected either completely or partially.
    The air flow rectifier 4a, 4b is adjustably arranged in relation to the air flow passage 3a, 3b via recesses 5 to the air flow passage 3a, 3b. This is illustrated i.a. in Fig. 3 showing air flow directers 4a, 4b which are adjustably arranged through recesses 5 in a respective wall element 8a, 8b. The air flow rectifier 4a, 4b comprises air direction tabs 6.
    The air direction flaps 6 are configured to be able to be variably moved back and forth through said recess 5. The air direction flaps 6 consist of leaf-like elements. Furthermore, the air flow converter 4a, 4b comprises an elongate element 7a, 7b. This elongate element 7a, 7b has a rigidity which makes it function as an elongate beam element without being plastic. Said air direction flaps 6 are arranged to the elongate element 7a, 7b and together with the elongate element 7a, 7b form a unit.
    Said recess 5 is according to Fig. 3 arranged in a wall element 8a, 8b of the air flow passage 3a, 3b. Respective air direction flap 6 can be adjustably arranged through respective recesses 5. The recesses 5 consist of a number of openings which are arranged at a distance relative to each other through the wall element 8a, 8b. The respective distances between adjacent recesses 5 10 15 20 25 30 PM30171SEOO 6 can be even. By this it is obtained that the air direction flaps 6 can be evenly and symmetrically distributed over the length of the wall element 8a, 8b and along the width of the air flow passage 3a, 3b. By said symmetry a uniformly directed air flow 2 of the part of the air flow which is affected by the air direction flaps 6 is obtained.
    The wall element 8a, 8b, see Fig. 2 is arranged along an outlet 9a, 9b to the supply air device 1, through which outlet 9a, 9b the air flow 2 is led into the room. The outlet 9a, 9b can be arranged so that when the supply air device 1 is arranged in a roof, said outlet 9a, 9b is substantially flush with the roof and then preferably the suspended ceiling of a room. According to the embodiment according to Fig. 2, the supply air device 1 comprises two outlets 9a, 9b. The outlets 9a, 9b are arranged in parallel in the supply air device 1 so that the air flow 2 can be led out of the supply air device 1 with optimal distribution. An optimal spread is an air flow that spreads in directions that essentially diverge from a supply air device. The aim is for the outflowing air, which normally has a slightly lower temperature, to be the room air, to be spread over as wide an area, area, as possible along the roof from the supply air device. This is due to that cold, cooled, air is heavier, and by spreading the cooled air over a large area, the time for the air before it begins to sink into the room and mix with the existing room air can be delayed, and mixing of the air from the supply air device with the room air is improved because the mixing thus takes place over a larger area in the room and thus with a larger volume in the room. In the event of poor or inefficient distribution of the air from the supply air device, it can result in the cooled air falling straight down from the supply air device, whereby the mixture between the cooled air and the room air deteriorates in large parts of the room.
    Figs. 2 and 3 show how the wall element 8a, 8b divides the air flow passage 3a, 3b from a control space 10a, 10b, which control space 10a, 10b extends along the outlet 9a, 9b and is formed by the wall element 8a, 8b and a bottom part 11 of the supply air device 1. .
    The bottom part 11 can also be called a lower plate. Respective wall elements 8a, 8b may be constituted by a part which is folded or bent from or at the edge area of the bottom part 11 to form said wall elements 8a, 8b. The wall elements 8a, 8b have an air flow surface which faces the said air flow passage 3a, 3b. The air flow passage 3a, 3b can be formed between said air flow surface and an inside to a housing of the supply air device 1. On an inside, opposite the air flow surface, the control space 10a 10b is arranged. The control space 10a 10b is delimited between the inside and bottom part of said wall elements 8a, 8b. The control space 10a, 10b can be considered to constitute the space created between the wall elements 8a, 8b. 10 15 20 25 30 PM30171EN00 7 Alternatively, the control space can be considered to consist of a space created between the wall elements 8a, 8b and a cooling element arranged therebetween.
    The elongate element 7a, 7b of the air flow converter 1 is arranged in the control space 10a, 10b. Said elongate elements 7a, 7b are formed with a length which is shorter than the control space 10a, 10b.
    The air direction flaps 6, see Fig. 3 are arranged from the elongate element 7a, 7b in the control space 10a, 10b and through the respective recess 5, opening, in the wall element 8a, 8b.
    Because the elongate element is arranged in the control space 10a, 10b, disturbing turbulence occurs in the outgoing air flow 2 from the supply air device 1.
    The air flow rectifier 4a, 4b may comprise at least one control means 12a, 12b for positioning the air flow rectifier 4a, 4b in the air flow passage 3a, 3b. Control means 12a, 12b may be arranged against the elongate element 7a, 7b of the air flow rectifier 4a, 4b at a respective end thereof. Respective control means 12a, 12b can extend through a passage in the bottom part 11 in order to be able to be regulated from inside the room by a person extending up to the control means 12a, 12b, not shown in figure. According to an embodiment, not shown in the figure, the control means 12a, 12b may be associated with an electronic unit for automated control.
    Fig. 4 shows an air flow converter 4a, 4b according to the invention. The air flow rectifier 4a, 4b is arranged with air direction flaps 6 which are arranged from an elongate element 7a, 7b.
    The air direction flaps 6 and the elongate member 7a, 7b are configured to together form, or form, a unit. The air direction flaps 6 and the elongate element 7a, 7b can be formed by a material element, e.g. a sheet metal plate. The air direction flaps 6 can be formed by the material element by means of e.g. cutting, cutting or punching, said flaps thereby forming said air direction flaps 6. From the material element, the air direction flaps 6 can be angled to obtain an angled position relative to the elongate element 7a, 7b. The angle also means that the air direction flaps 6 can be fitted into the recesses 5 in order to be adjustably arranged in the air flow passage 3a, 3b.
    Fig. 4 shows a part as circled. This refers to an enlargement of the end portion of the air flow converter 4a, 4b for clarification. In the magnification it is shown that the respective air direction flap 10 15 20 25 30 PM30171EN00 8 6 on an outer part is bent, folded. As a result, an improved control of the air flow 2 which is deflected from the outlet 9a, 9b into the room is obtained.
    According to one embodiment, the air flow rectifier 4a, 4b can be arranged in the air flow passage 3a, 3b by the air flow rectifier 4a, 4b being moved, pushed or pressed, horizontally with the bottom part 11 in the direction of the outlet 9a, 9b. An effect of this embodiment is that the bottom part 11, the lower plate, supports the air flow converter 4a, 4b. Thus, no further supporting elements are needed to arrange the air flow converter 4a, 4b in the supply air device 1.
    During this movement, the air direction flaps 6 are pushed through the respective recesses 5 into the air flow passage 3a, 3b. In relation to the air flow passage 3a, 3b, the air direction flaps 6 have an angle which means that when they enter the air flow passage 3a, 3b, the air direction flaps 6 will deflect an outgoing air flow 2 out of the air flow passage 3a, 3b. When the air flow rectifier 4a, 4b is moved into the active position in the air flow passage 3a, 3b, the air flow rectifier 4a, 4b can be regulated in such a way that one end of the air flow rectifier 4a, 4b can be moved further into the air flow passage 3a, 3b compared to the other end. . This results in that the air flow rectifier 4a, 4b can be arranged with a varying angle of the air flow 2 out of the outlet 9a, 9b in that the air flow 2 can have an increasing or decreasing angle towards e.g. an end portion of the elongate outlet 9a, 9b. Such a design makes it possible to obtain a further distribution of the air flow 2 from the supply air device 1. The aim may be to obtain a distribution of the air flow 2 out of the outlet 9a, 9b which is similar to a so-called fan shape. By arranging in the longitudinal direction of an air flow passage 3a, 3b two successively arranged air flow directors 4a, 4b, said fan shape of an outflowing air stream 2 can be obtained. This then takes place in that the respective end portion which adjoins each other of the two air flow directors 4a, 4b in the air flow passage 3a, 3b are arranged in an inactive position. The respective other ends of the respective air flow directors 4a, 4b are arranged in an active position. This results in the outflowing air stream 2 along a central portion of the outlet 9a, 9b receiving a direction of fate from the supply air device 1 which is substantially not angled. The angle of the air flow 2 out of the outlet 9a, 9b increases from the middle portion of the outlet 9a, 9b in the direction of the end portion of the respective air flow rectifier 4a, 4b.
    Through said two air flow rectifiers 4a, 4b arranged one after the other in the air flow passage 3a, 3b, said fan shape of the outflowing air stream 2 from the outlet 9a, 9b of the supply air device 1 can thus be obtained. According to one embodiment, the air flow rectifier 4a, 4b can be arranged in the air flow passage 3a, 3b by moving the air flow rectifier 4a, 4b in a vertical direction relative to the bottom part 11 up through the recesses 5 and into the air flow passage 3a, 3b, not shown. ifigur.
    Because the wall element 8a, 8b is angled in relation to the bottom part 11, the air flow rectifier 4a, 4b with the air direction flaps 6 can be pushed up through said recess 5 in order to be variably arranged in the air flow passage 3a, 3b.
    According to a further embodiment, the air flow converter 4a, 4b can be arranged in the control space 10a, 10b so that the air flow converter 4a, 4b is rotatably arranged in its longitudinal direction, not shown in figure. Because the air flow rectifier 4a, 4b is rotatable, the air direction flaps 6 can be rotatably arranged in position into the air flow passage 3a, 3b through the recesses 5 through wall elements 8a, 8b.
    According to a further embodiment, the air flow rectifier 4a, 4b can be arranged so that its air direction flaps 6 can be moved into the air flow passage 3a, 3b in an active position from a top side in the direction of the wall element 8a, 8b. The top can e.g. consists of a housing of the supply air device 1 or other upper element for forming the air flow passage 3a, 3b between said wall elements 8a, 8b and the housing or the upper element.
    The invention is not limited to the embodiment shown but can be varied and modified within the scope of the appended claims, which has been partly described above.
