    20 25 30 A disadvantage of existing devices is that the air blown into the room is often too cold or too hot, as it often has to be several degrees warmer or colder than the average room temperature in the lower part of the room.
    Furthermore, if the air speed is too high, this is perceived as disturbing for people staying in the room.
    Object of the invention Against this background, a main object is included. the invention to provide a supply air device which provides a well-controlled. inflow of air into the room, without too high an air velocity but during the formation of a stable air inflow, whereby the climate in the room is kept comfortable. Another purpose, in the event that the air blown into the room is heated or cooled, is to reduce the temperature difference between the air in the supply air diffuser and the average room temperature.
    Summary of the Invention According to the present invention, these objects are achieved in that the housing of the supply air device has two opposite, first and second side walls and a third wall therebetween, where the supply air opening is located, and that two opposite, parallel, longitudinally extending pocket-like portions are formed inside the housing on each side of the supply air opening, adjacent the first and second side walls, and that the supply openings in the feed pipe are located and designed so that the supply air is caused to flow into the pocket-like portions and cause a tornado-like air flow in each pocket-like portion. circulates in the tornado-like air flow interacting with air from the room before it flows out through the supply air opening to the room. Due to the tornado-like air flow, a static pressure drop occurs next to the circulating air, which sucks in ambient air to the interior of the housing. Thus, even if there is a net flow of air outwards through the supply opening, a certain air flow also arises in the opposite direction, from the space next to the air diffuser to the interior of the housing. In this way, the inlet air will mix slightly with the room air before it is blown out through the supply air opening. Thus, an interaction and a certain equalization of the inlet air and the room air occur. Consequently, persons staying near the supply air device will not feel the difference as much as was the case with previously known supply air devices of this type. This is particularly marked if the inlet air is much colder than the room temperature.
    According to a further aspect of the invention, the nozzle openings in the feed pipe may comprise at least two rows of air nozzles or openings, each row extending longitudinally along the housing and the nozzles or openings being directed obliquely towards the first and second side walls. Preferably, such rows of air nozzles or openings are formed to form an air curtain which strikes at an acute angle to the first or second side wall, after which the air is deflected and transformed into the above-mentioned tornado-like air flow in associated pocket-like portion. With such an arrangement, a stable air flow can be maintained even at three or more relatively low air flows. There may be two, rows of nozzles or openings on each side, which form associated air curtains which at slightly different angles strike the inside of the first and second side walls of the house.
    Thanks to the respective relatively high air velocity in the air curtain, an additional suction effect arises, which sucks air from the room through the supply opening to the interior of the housing.
    Preferably, the rows of air nozzles or openings are located so that they direct the air curtains obliquely towards the respective pocket-like portion on each side of the supply opening.
    The pocket-like portions can be delimited by straight wall portions with mutually right angles, for example designed as parts of said first and second side walls, a part of the third wall and flange walls extending along the supply opening inwards from the third wall to the interior of the housing.
    Alternatively, each pocket-like portion may be at least partially defined by a semicircular wall portion which merges into the first or second side wall of the housing.
    In order to heat or cool the supply air, heat exchangers can be arranged in one or both pocket portions, for example in the form of longitudinally extending pipes for the flow of a hot or cold fluid. This provides a particularly efficient heat exchange, as the supply air circulates in the pocket and thereby interacts efficiently with the hot or cold pipes. Of course, the pipes can be fitted with flanges or the like to make the heat exchange even more efficient.

In the latter case, it is advantageous to arrange an extended chamber next to the air supply opening and to mount an upper grid flush with the floor for the flow of the supply air to the room.
    These and other features are set forth in the dependent claims and will also be apparent from the following detailed description, taken in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows diagrammatically, in perspective view, a supply air diffuser according to the present invention, wherein an end wall of the housing is omitted to make the interior of the housing visible; Figure 2 shows, also in perspective view, an air supply pipe, on a larger scale; Figure 3 shows a cross-section through the housing of the supply air device according to Figure 1; Figure 4 shows a 1nodified. embodiment of the supply air device according to the invention; Figure 5 shows schematically how the supply air device according to the invention can be mounted on a wall in a room; Figure 6 'shows an alternative' mounting 'of the supply air device on the floor next to a room wall; and Figure 7 shows how the device can be mounted in the floor of a room.
    DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS The supply air device 1 shown in Figures 1, 2 and 3 comprises a box-like, elongate housing 2, a supply pipe extending inside and along the housing 2 and a supply air opening 4 in a wall of the housing. The elongate housing 2 in this embodiment has a rectangular cross-section (figure 3) with upper and lower, first and second walls 21 and 22 and a third wall 23, which extends between the opposite walls 21, 22 and It is provided with . the above-mentioned supply air opening 4. later 76015 Translation 10 15 20 25 30 extends in the longitudinal direction of the housing along a large part of the third wall 23, as is clear from Figure 1. The elongated extent of the supply air opening 4 may be shorter or longer than that shown in figure l.
    The supply pipe 3 is connected to a supply air duct or some other source (not shown) for fresh supply air. In the ring shape shown, the feed pipe extends along the length of the housing 2. The air supply pipe 3 is cylindrical with a circular cross-section (figure 3) in this embodiment, but the cross-sectional shape is not critical. At. the left of the house. end, as shown in Figure 1, the housing 2 is closed with a gable wall (not shown), and the feed pipe 3 should either be provided with a closing gable wall or be connected to an extended supply air duct.
    As is clearly shown in Figure 2, the air supply pipe 3 is provided with four rows of small supply openings or nozzles 31, 32 and 33, 34, which rows are mutually parallel and extend along the length of the pipe 3, at least along a length corresponding to the supply air opening 4. .
    These feed openings 31, 34 consist of relatively small circular holes, preferably with a diameter not exceeding 5 mm, in particular about 4 mm and not less than 3 mm. Instead of drilled holes, these openings can be formed by punched holes with a collar, or they can consist of a separate insert part, which is designed so that it provides a well-defined air flow. In each case, the air currents from the cavity 31-34 form an air curtain directed radially outward from each cavity.
    According to the invention, the feed openings in the form of hollow rows 31-34 should be arranged in such a way that they direct the air-free (see figure 3) obliquely towards the fountains C1, C2 and C3, respectively. C4 76015 Translation first and the second side wall 21, 22, in the direction of the third wall 23.
    In this way, the air curtains C1-C4 strike at an oblique angle to the first and second side walls 21, 22 of the housing, and are subsequently deflected and converted into a tornado-like air flow in an adjacent area of the housing, to the right in Figure 3.
    For this purpose, the housing portions on either side of the supply air opening 4 are designed as a pocket-like configuration which serves to transmit the flowing air to an elongate, circulating air flow with a tornado-like configuration. This is schematically illustrated in Figure 3 with arrows T.
    In the embodiment shown in Figures 1-3, the pocket-like portions 25 of the housing are formed by a part of the first and upper upper second side wall 21, 22, respectively (to the right in Figure 3), or lower part of the third wall 23. , and a flange wall extending along the supply air opening 4 inwardly from the third wall. 23 to the interior of the housing 2. These flange walls are designated 24. Thus, the supply air opening is designed as a rectangular box with open sides (see also figure 1).
    In order to maintain a steady air flow inside the housing 2, the curtains C1, C2, C3, C4 or the jets (possibly distributed in the longitudinal direction) must have a certain speed, typically in the range 8-14 m / s. Furthermore, the inclination of these curtains or jets C1, C2 and C3, C4 will facilitate the formation of the tornado-like air flow in the two pocket-like portions 25. Alternatively, the holes or nozzles 31-34 may be located in another part of the air supply pipe 3. , for example so that they form an increased air pressure in the left 76015 Translation 10 15 20 25 30 part. of the 'house interior (figure 3) varigenonx the air. will * flow to the right to the respective pocket-like portion 25 of the housing. The cross-sectional shape of the feed tube 3 may further be different from the cylinder shape shown, for example it may have a rectangular cross-section, provided that the feed openings are arranged so as to transfer the supply air to the two pocket-like portions of the housing.
    The pocket-like portions of the housing can be modified to facilitate the formation of tornado-like air currents. An example is shown in Figure 4, where each pocket-like portion 25 'is formed by a part of the wall 21', 22 ', an inwardly directed flange 24' and a semi-cylindrical wall part 23 'therebetween. In this modified embodiment, there are no sharp corners inside the pocket-like ones, so that the circular tornado-like portions of the air flow are facilitated. In other respects, the embodiment according to Figure 4 is the same as the previous embodiment, and the same reference numerals are used for corresponding construction details.
    A further aspect of the present invention is the possibility of arranging heat exchangers 5 in the interior of the housing 2, preferably in one or both pocket portions 25 '. The heat exchangers can be designed as electric heating elements or, preferably, in the form of tubes 51, cold fluid, 52 for the passage of a hot or as water, or water mixed with another liquid, for example ethanol. Since these heat exchangers 5 are located inside the tornado-like air stream, the heat exchange will be particularly efficient.
    Of course, the schematically shown pipes 5 in the drawing can be connected to sources (not shown) for hot and / or cold fluids. In such connected pipeline systems, control devices can further be arranged for regulating the temperature above or below the room temperature, or for switching off the heat exchangers. The pipelines can also be provided with radial flanges or the like to further increase the heat exchange.
    Practical tests have shown that the supply air device 1 according to Figure 1-3 works very efficiently. Of course, a net air flow is maintained from the interior of the housing 2 via the supply air opening 4 and into the adjacent part of the room, which net air flow is indicated by the arrow S in Figures 1, 13 and 4. At the same time there is a certain air flow from the adjacent part of the room internal, such a backward flow of air being caused by the slightly lower static pressure formed by the high velocity air flow in the air curtains C1-C4 and the tornado-like air currents T. These opposing air currents (see arrows B in Fig. 3-4) causes an irregular, turbulent air flow in the supply air opening 4.
    It should be pointed out that the arrows S and B are schematic and do not necessarily illustrate the exact air flow in the area outside the supply air opening 4.
    However, it has been found that the net air flow from the supply air device 1 has a large moving force or amount of movement, even if the air velocity is not very large, and the somewhat diffuse or turbulent air flow S will not disturb persons staying in the immediate vicinity of the supply air device. . Rather, the net air flow is perceived as comfortable for people and there is also a mixture of ambient room air and the supply air inside the house. Consequently, in the event that the supply air is colder or warmer than the air temperature in the room, a certain equalization of the temperature in the house occurs. In particular, if cool air is supplied when the room air is hot, the air flow, S into the room, will be slightly preheated before leaving the supply air opening 4. Thus, 76015 Translation 10 15 20 25 30 10 also surrounds room air in the heat exchange, through the rearward direction the air flow B through the supply air opening 4.
    In the manner described above, the main object of the invention is achieved by the supply air device 1, as described above, in particular for providing a comfortable climate in the room.
    Figures 5, 6 and 7 show some examples of the location of the supply air device. In Figure 5, the second wall 22 of the housing 2 is attached to a wall W in the room, with the longitudinal direction of the housing 2 oriented horizontally, at some distance above the floor E 'in the room; and the supply air opening 4 is directed downwards towards the floor F. It will be understood that instead of the second walls 22 being attached to the room wall, the first wall 21 housing the housing 2 can be attached to a room wall so that the supply air opening 4 is directed downwards towards the floor F.
    The distance between the supply air opening 14 and the floor E "can be about 100 mm. For good function. Of the supply air device, but, other distances are also possible, as will be understood by the person skilled in the art.
    In figure 6 than: the supply air device 1 Recessed standing j on the floor F next to a wall 'W, with. the fourth side wall 26 attached to the wall. In this case, the elongate supply air opening 4 (not visible) is oriented in the vertical direction.
    In Figure 7, the supply air device 1 is mounted in a chamber or duct 6 below the floor surface. An extended portion 7 of the chamber is arranged next to the supply air opening 4. The supply air passes through the extended portion 7 of the chamber via an upper grid 8.
    The supply air device according to the invention can be modified in many ways within the scope of the appended claims. There may be more than two rows of holes or nozzles 31-32 and 33-34 on each side of the supply air opening 4. Any heat exchangers 5 76015 Translation 10 15 20 25 30 ll can be arranged in another way, for example on the other side of the supply pipe 3 (left in Figure 3).
    The feed pipe. 3 can be integrated with. the house, so that it is partially delimited by a house wall, for example the fourth wall above. 26, such as. is indicated The feed pipe may alternatively have a different cross-sectional shape.
    The supply air opening 4, which is delimited by flange-like wall portions, may be slightly inclined (upwards or downwards in figure 3).
    Furthermore, equipment or components can be arranged inside the supply air device 1, such as control equipment, devices for regulating the air flow, temperature sensors and the like.
    As for the location of the supply air device 1, it can be placed and oriented in the desired manner, for example at some other construction part in the room, for example at a pillar, a partition wall or the like. 76015 Translation
