    15 20 25 30 35 2 The room air through the battery is then brought into the supply air diffuser to mix with cooler fresh air from a ventilation system. The mixed air is then led out into the adjoining room.
    For efficient ventilation, this requires that the supply air device has a high induction force. In order to be able to have the necessary induction force in the prior art, a large volume flow of so-called new air so that this air can thereby have a high speed in order to thereby mix and draw the temperature-affected air from the temperature battery out of the supply air device. However, in order for a high induction effect, and thus a good mixing of the air in a room with such known constructions, in the same way as described above, here too a feeling of discomfort from blowing or drawing in the room can arise when the mixed air is sprayed from the supply air device. into the room.
    SUMMARY OF THE INVENTION An object of the present invention is to overcome the above-mentioned problems.
    A further object of the present invention is to be able to regulate the volume and velocity of an air through a supply air device without sound occurring.
    A further object of the present invention is to create a supply air device where even small amounts of air out of the supply air device to a room can have a high speed compared with conventional supply air devices.
    A further object of the present invention is that the supply air device should be compact and have a higher efficiency and efficiency compared to conventional devices.
    A further object of the present invention is that the speed of an air when passing through air flow passages in the supply air device is not to be affected when a flow area through the respective air flow passage is reduced.
    A further object of the present invention is that it should be easy compared with previously known supply air devices to regulate a flow of air out of the supply air device in partly different directions and partly with varying volume flows.
    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 included in claim 1.
    An advantage achieved with a device according to claim 1 included in features is that small volumes of air can flow out of the supply air device at higher speeds compared with previously known supply air devices. This at the same time as the sound is reduced.
    A further advantage achieved with a device according to claim 1 included in features is that the flow of air out of the supply air device is easy to control. This is partly with regard to the direction of the air flow into the room, and partly with regard to the air volume into the room from the supply air device. A further advantage achieved with a device according to claim 1 included in features is that the respective air flow from the respective side of the supply air device can be regulated as desired.
    A further advantage achieved with a device according to claim 1 included in features is that the speed of the air flow out of the air flow passages in the supply air device is high, or unchanged, when reducing the flow area of the respective air flow passages. This means that a high induction rate or induction power, as well as a high efficiency in the supply air device can be obtained.
    Preferred embodiments of the device have furthermore been given the features set out in subclaims 2 to 13.
    According to a further embodiment of the invention, the air flow passages are convergently nozzle-shaped. An effect of this is that the speed of the air when passing through the respective air flow passage is thus accelerated out of the main chamber. As a result, the air thus also obtains a good control and stability during its passage through the supply air device out of the air flow passage in the direction of an outlet in the supply air device. An advantage of this is i.a. that even small air flows can thus have a high speed for further travel into the room to be ventilated.
    According to an embodiment of the invention, the bottom plate comprises edge portions and in which at least one edge portion the air flow passages are arranged. An effect of the air flow passages being arranged in the edge portions is that a larger temperature battery compared with known technology can thus be used in the supply air device. This without the external air supply external dimensions having to be affected.
    According to an embodiment of the invention, each member has a convexly shaped outer side. An effect of this is that the volume of air passing through an air flow passage can thus vary linearly when the member is regulated in a direction inside and through the air flow passage. The linear increase or decrease of the air flow through the air flow passage occurs upon movement of the member within an air flow passage in and along the direction of the member through the air flow passage. When the member is moved out of the air flow passage, in a direction of movement away from the bottom plate, the air flow increases linearly through the air flow passage. When the member is moved into the air flow passage, in a direction of movement towards and through the bottom plate, the air flow decreases linearly through the air flow passage. This linear increase and decrease can be controlled manually by means of level control means which are arranged with a gradation in order to be able to visually see which air flow the supply air device is set to.
    According to an embodiment of the invention, each member has a free end arranged opposite the beam element which is rounded. An effect of this is that it is sought to always have at least a part of the member arranged in the air flow passage. This is to prevent noise. According to an embodiment of the invention, the respective means are arranged in the respective air flow passage in such a way that the means is not necessarily centered in the air flow passage. One effect of this is that tolerances during manufacture thus do not have to be so accurate, which in turn reduces manufacturing costs for the device. This is because i.a. time does not need to be used to check any mentioned tolerances.
    The flow area through an air flow passage does not depend on whether the means is arranged centered or not.
    According to an embodiment of the invention, the air flows into an outlet chamber upon passage through the air flow passages. One effect of this is that the air receives a pressure drop through passage through the air flow passages. During the passage of the air through the air flow passages into the outlet chamber, a negative pressure is thus formed in the outlet chamber. An additional effect is that the speed of the air is accelerated during this passage due to. that the airflow passages are nozzle-shaped.
    According to an embodiment of the invention, an air diffuser is arranged in the outlet chamber. An effect of an air diffuser being arranged in the supply air diffuser is that the air can thus be angled away from the diffuser when entering a room. An additional effect is that a coanda effect is obtained in the air flowing out of the supply air diffuser into the room.
    The coanda effect means that the air flows along the ceiling, and does not fall straight into the room.
    This results in a better distribution of the air from the supply air diffuser into the room.
    According to an embodiment of the invention, at least one temperature battery is arranged in the outlet chamber. With the help of induction effect, air flows from the room, so-called room air, into and through the temperature battery to the supply air device. This i.a. pga. above-mentioned negative pressure in the outlet chamber. An effect of the induction effect being used in the supply air diffuser is that the room air can thus be mixed and tempered with new air in an efficient manner and then subsequently reintroduced into the room together with the new air. An additional effect is that the new air, which usually has a lower temperature than the room air when mixed with the room air, is thus prevented due to its weight when flowing out of the supply air diffuser to fall to the floor of the room. This is because cold air is heavier than hot air, with cold air falling down.
    According to an embodiment of the invention, the control element comprises level control means. An effect of the level control means is that these are arranged with a gradation. When adjusting, the rating states e.g. the size of the volume of air flowing through the respective air flow passage. When regulating the level control means, the air flow varies linearly from the respective air flow passage. The gradation is arranged in such a way that when setting the level control means a distance along its gradation, the air flow through the respective or the entire supply air device can thus be read. The gradation also makes it possible to read the air flow out of the supply air device in a selected direction. According to an embodiment of the invention, the level control means are connected to at least one end portion of the respective beam elements. An effect of this is that the end portions of a beam element can thus be adjusted to different heights above the air flow passages. Through this you can therefore adjust so that the air flow is greater, or smaller, through different parts of the bottom plate. This is because the respective means arranged on the beam element are thus arranged at varying levels inside the respective air flow passage.
    According to an embodiment of the invention, the respective level control means extends from the respective connected end portion, through a recess in the bottom plate, to at least one fixing element arranged on the supply air device. An effect of this is that it is thus possible to fix the respective means a desired position in the respective air flow passage.
    According to an embodiment of the invention during operation, a first main pressure drop of the air through the supply air device takes place when the air passes through the air flow passages from the main chamber to the outlet chamber. An effect of this is that the pressure drop takes place just before the air is to be led out into the room, whereby a smaller volume of air at a high speed can thus be led into the room. Pga. the high air velocity, a smaller volume of air is therefore sufficient, compared with previous constructions, to efficiently mix and ventilate a room comprising unmixed air.
    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 show only the details necessary for understanding the invention.

    Fig. 2 shows a view of a supply air device where part of the outer casing has been removed.
    Fig. 3 shows part of a beam element together with means air flow passages arranged in part of a bottom plate.
    Figs. 4 - 6 show means arranged in different levels through an air flow passage.
    Fig. 7 shows a cross section through an alternative embodiment of a supply air device with drawn air flows.
    Detailed description of preferred embodiments of the invention Fig. 1 shows part of a supply air device (1) via a cross section through the supply air device (1), The supply air device (1) according to the figure is configured to be arranged in a ceiling to a room (the roof is not shown in figure ). The supply air device (1) is arranged to be permeated by air (3). The air (3) comes to the supply air device (1) from a source, e.g. a ventilation system by means of ducts or pipes (not shown in figure). After passage of the air (3) through the supply air device (1), the supply air device (1) is arranged to direct the air (3) into the space adjacent to the supply air device (1). The air in the room will thus be 10 15 20 25 30 35 6 of the air (3) from the supply air device (1) ventilated and blended with “new” air. The supply air device (1) comprises an inlet chamber (21) to which the air (3) primarily enters before it passes through the rest of the supply air device (1). The inlet chamber (21) is arranged against a wall element which adjoins a main chamber (2) in the supply air device (1). The inlet chamber (21) is provided with a main opening (22). The main opening (22) is flowed through by the air (3) from the source. Inside the main chamber (21) an inlet (4) to the main chamber (2) is arranged.
    The air (3) from the source is led through the supply air device (1) via the main opening (22) into the inlet chamber (21). From the inlet chamber (21) the air (3) is led into the supply air device (1) through the inlet (4).
    In the figures comprising arrows for air is air which comes to the supply air device from the source and has not been mixed with other air from e.g. a room represented by arrows which are white. Air that comes from a room into the supply air diffuser and has not been mixed with air from the source is represented by arrows that are black. Air inside the supply air diffuser is a mixture of air from the source and air from the room is represented by arrows which are striped in black and white. The inlet (4) is provided with a perforated plate through which the air (3) passes. (21) the main chamber (2). Inside the main chamber (2), along said wall element, a wall element comprising the inlet (4) separates the inlet chamber from turbulence-creating means (19) is arranged. When the air (3) passes the turbulence generating means (19), a turbulence is created in the incoming air (3) inside the main chamber (2).
    Due to the turbulence, the air (3) has a substantially even distribution inside the main chamber (2). In the preferred embodiment, the turbulence generating member (19) has a shape resembling a sawtooth pattern. Inside the main chamber (2) a bottom plate (5) is arranged. The base plate (5) separates the main chamber (2) from an outlet chamber (11). The bottom plate (5) comprises edge portions (Sa, 6b, 6c, 6d) which extend around the peripheral area of the bottom plate (2) (only 6a and 6c are shown in the figure). The edge portions (Ga, 6b, 6c, 6d) adjoin wall elements of the supply air device (1) and (6a, 6b, 6c, 6d) air flow passages (7a, 7b, 7c) are arranged (only 7a and 7b are shown in the figure). In this case, they are preferably connected to the wall elements. In the edge portions of the document, only three of the air flow passages (7a, 7b, 7c) are indicated by figure references.
    This does not mean that there are only three airflow passages. In the figures (see Figures 2 and 3) it can be seen that several air flow passages, more than three, are arranged in the edge portions (Ba, 6b, 6c, 6d). The width of the respective edge portion (6a, 6b, 6c, 6d) is defined by the diameter of the respective air flow passages (7a, 7b, 7c). This means that each edge portion (6a, 6b, 6c, 6d) must have a width, seen in a perpendicular direction from the adjacent wall element to the edge portion (6a, 6b, 6c, 6d), which is larger than the diameter of the respective air flow passage (6a, 6b, 6c, 6d) arranged in the respective edge portion (6a, 6b, 6c, 6d). This is so that an air flow passage (6a, 6b, 6c, 6d) can fit in the edge portion (6a, 6b, 6c, 6d). 10 15 20 25 30 35 7 Inside the supply air device (1) a control element (10) is arranged controllably. The control element (10) comprises at least one beam element (12a, 12b, 120, 12d). In the preferred embodiment, four beam elements (12a, 120, 120, 12d) (shown in the figure only (12a and 120) are arranged with each other, forming a frame-like structure in the form of a square. Respective beam elements (12a, 12b, 120, 12d) comprises an end portion (not shown in the figure), and which end portions in the preferred embodiment are connected to each other forming said frame-like structure.The beam element is arranged inside the main chamber at a distance from the air flow passages (7a, 7b, 70) in the edge portions (6a , 6b, 60, 6d).
    The control element (1) comprises, in addition to the respective beam elements (12a, 12b, 120, 12d), also means (13a, 13b, 130). Said means (13a, 13b, 130) are provided with one end against the beam element (12a, 12b, 120, 12d), and directed in a direction from the beam element (12a, 12b, 120, 12d) towards and through an air flow passage (7a, 7b, 70). The direction of the respective members (13a, 13b, 130) from the beam element is perpendicular to the beam element (12a, 12b, 120, 12d), and perpendicular to a plane in which the edge portion of the bottom plate is arranged. A second end of the body is free. The member has a tapered cross-sectional area in the direction per unit length. The direction of the respective members (13a, 13b, 130) is defined from beam elements (12a, 12b, 120, 12d) to which the member (13a, 13b, 130) is arranged and in extension by the free end of the member (13a, 13b, 130) .
    At least one temperature battery (24) is arranged in the outlet chamber (11).
    The temperature coil (24) cools or heats room air that is sucked up from the room and into the supply air device (1) by means of induction. Inside the outlet chamber (11), the temperature-affected air that has passed through the temperature battery (24) is led from the room towards the wall element of the supply air device (1). At the wall elements, the air (3) which has passed through the air flow passages (7a, 7b, 70) flows into the bottom plate (5). The temperature-affected air (24) the air (3) the air flow passages (7a, 7b, 70) and "pulled" out through a main opening (22) from the temperature battery will here be mixed with from the supply air device (1) and into the adjacent room.
    An air diffuser (23) is arranged in, or at, the main opening (22). The air diffuser (23) angles the air (3) out of the supply air diffuser (1) into the room. By using an air diffuser (23), the size of a temperature battery (24) can be optimized to have as large the supply air device (1) the air flow passages (7a, 7b, 70) and air from the room through the temperature battery (24) along the flow area as possible. air (3) from with wall portions of the outlet chamber (11), in a substantially vertical direction, down towards the air diffuser (23) which angles the air (3) into the room (see striped arrows). Since the flow of air in the supply air device (1), inside the outlet chamber (11) takes place along said wall portions of the outlet chamber (11), a temperature battery (24) can therefore be so large that it leaves a passage between it and said wall element inside the outlet chamber (11) . Fig. 2 shows an air diffuser according to Fig. 1 where two wall elements and an upper part have been removed to clarify the inside of the air diffuser (1). Fig. 2 shows that the control element (10) is adjustably arranged by means of level control means (16a, 16b, 160, 16d) (16d is not shown in figure). Respective level control means (16a, 16b, 160, 16d) extend from an end portion of the respective beam elements (12a, 12b, 120, 12d). In the preferred embodiment, a level control means (16a, 16b, 160, 16d) is arranged in respective corners of the frame-shaped structure of connected beam elements (12a, 12b, 120, 12d). Respective level control means (16a, 160, 160, 16d) extend from said beam elements (12a, 12b, 120, 12d) in a direction parallel to respective means (13a, 13b, 130) from beam elements (12a, 12b, 120, 12d). , through a recess in the bottom plate (5) of a fixing element (1a, 18b, 180, 18d) arranged in the outlet chamber (11) (18d is not shown in figure). In each corner area of the base plate (5), respective recesses for passing through the respective 16b, 160, 16d) are arranged. An alternative to the fixing element (18a, 18b, 180, 18d) may also be that at least one fixing element is level control means (16a, placement of arranged in, or below the main opening (22) of the supply air device (1) (not shown in figure).
    Respective level control means (16a, 16b, 160, 16d) can extend a shorter distance out from the main opening (22) and into the room to facilitate control of the air diffuser.
    Fig. 3 shows a view of a beam element (12a, 12b, 120, 12d) according to the invention with a number of the previously mentioned members (13a, 13b, 130) arranged. Respective means (13a, 13b, 130) are fixedly connected to the base element (12a, 12b, 120, 12d). in the preferred embodiment, the base member (12a, 12b, 120, 12d) and the members (13a, 13b, 130) are made of one and the same material. The means (13a, 13b, 130) have a direction from the beam element (12a, 12b, 120, 12d) towards and through the respective flow passage (7a, 7b, 70) 13b, 130) from the beam element is perpendicular to the beam element (12a, 12b, 120 , 12d), and perpendicular to the plane in arranged in the base plate (5). The direction of the respective members (13a), on which the base plate is arranged. The beam element (12a, 12b, 120, 12d) has a web in the form of a truss. Through this the weight and material access of the beam (12a, 12b, 120, 12d) can be reduced to a minimum during manufacture while its bending and strength properties can be maintained, whereby material costs can be minimized, respectively. The respective members (13a, 13b, 130) have a cross-sectional area as per a unit of length in the said direction for each member (13a, 13b, 130). The outside of the respective members (13a, 13b, 130) is convexly formed on the part which is tapered, said cross-sectional area through the respective members being seen to lie in a plane parallel to the bottom plate.
    The air flow passages (7a, 7b, 70) in the base plate (5) according to the preferred invention are convergently nozzle shaped. Through this, the air (3) passing through the air flow pass from the main chamber (2) can be accelerated to a higher velocity into the underlying outlet chamber (11). 10 15 20 25 30 35 9 l Fig. 3 are arrows drawn to show what air flows through an air flow passage look like.
    After passing through the air flow passage, the air flows in a straight direction along a center axis through the respective air flow passage.
    Figs. 4a and 4b show the member (13a) in a first position where the flow area (9a) is maximally open. The free tapered end of the member (13a) is with a part arranged in the air flow passage (7a). Because a small part of the member (13a) is arranged in the air flow passage (7a), the risk of noise occurring when the air passes through the air flow passage (7a) is reduced.
    Figs. 5a and 5b show the member (13a) in a position controlled from position of Figs. 4a and 4b where the flow area (9a) is open to approximately 60%. The free tapered end of the member (13a) is arranged with a larger part in the air flow passage (7a). The member (13a) in this position has a larger cross-sectional area, the member (13a) thereby filling in more of the flow area (9a) of the air flow passage (7a).
    Figs. 6a and 6b show the member (13a) in a position further regulated from the position of Figs. 5a and 5b where the flow area (9a) is open to approximately 30%. In Fig. 6a, the lower part of the member is circled with a dashed ring (25). This is to show that the free end of the respective means (13a, 13b, 130) consists of a pin-like element, so-called pin, which is directed in the direction of the member (13a, 13b, 130). This pin has a concave extension from the body. In other words, the transition from the body to this pin is concave. When the air flow passage (7a, 7b, 70) is maximally open, the means is arranged so that in (7a, 7b, the air flow passage. Or mainly through the air flow passage (7a, 7b, 70). This is shown in relation to the air flow passage 70). in Fig. 4a. This prevents noise from occurring when air flows through the air flow passage (7a, 7b, 70).
    When adjusting the position of the respective members (13a, 13b, 130) inside the respective air flow passage (7a, 7b, 70), there is a relationship between the length of the respective level control members (16a, 16b, 160, 16d) and the convexly shaped outside of the respective members. (13a, 13b, 130). The relationship is such that when adjusting the position of a member (13a, 13b, 130) in the direction inside an air flow passage (7a, 7b, 70), the volume of the air through the air flow passage (7a, 7b, 70) changes linearly.
    Level control means (16a, 16b, 160, 16d) are arranged with a scale in order to be able to be gradually adjusted to the desired level against the fixing element (18a, 18b, 180, 18d). This adjustment is done manually. An alternative is to arrange an automatic device that allows the control to be automated.
    Fig. 7 shows an alternative embodiment of a supply air device (101). Fig. 7 shows a cross section through the alternative supply air device (101). Air (103) flows from an external source as above into the main chamber (102). Inside the main chamber (102), the air (103) passes through 1D air flow passages (107a, 107b), which are arranged in a bottom plate (105) inside the main chamber (102). Inside the main chamber (102) control elements (110) are arranged.
    Control elements (110) comprise beam elements (112a, 112b). From each beam element (112a, 112b) means (113a, 113b) are arranged. In the same way as previously described, the respective means (113a, 113b) are controllably arranged in the respective air flow passage (107a, 107b). The main chamber (102) adjoins on the other side the base plate (105) to an outlet chamber (111). In the outlet chamber (111) a temperature battery (124) as previously described is arranged. The air (103) is led through the supply air device (101) from a source (in Fig. 7 represented by white arrows), passes through the bottom plate, enters the outlet chamber (111). Inside the outlet chamber (111), air (in Fig. 7 represented by black arrows) is sucked from an adjacent room to be ventilated by means of induction power into the outlet chamber (111) through the temperature battery (124). The air from the room (black arrows) that has passed through the temperature coil (124) is then directed towards the wall sections of the supply air device. At and along the wall portions, the air from the temperature battery is mixed with the air ejected from the air flow passages (107a, 107b, 1070) into a mixed air (in Fig. 7 represented by striped arrows). The mixing air (striped arrows) is then led out into an adjacent room through a main opening (122) for venting this room. The main opening (122) is arranged in the outlet chamber (111). An air diffuser (123) is arranged in the outlet chamber (111).
    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.
