    Terminal device for air flow
    The invention relates to a terminal device for airflow.
    The state of the art knows different types of airflow terminal devices, through which air can be diffused into a room or sucked into an exhaust pipe from the room. The air flow terminal devices usually include an air supply chamber and on its discharge side, a discharge surface, which may be formed by openings in a plate, by shutters, etc. Some devices have specific characteristics for air flow, such as air flow rate, pressure loss, noise development, flow velocity, and jet pattern. air flow, etc. Once the device is installed in the air conditioning system, it is difficult to make changes. When it is necessary to change the operating range of the air flow termination device, it is often necessary in this case to replace the complete terminal device.
    The present application proposes a novel solution to the problems mentioned above. It has been realized in the invention how to form a terminal air flow device by using a replaceable nozzle part, namely an inlet between the air supply chamber, namely the feed chamber. , and the air evacuation chamber, namely the evacuation chamber, of the structure. As the air flow terminal device thus comprises an air supply chamber and an air discharge chamber and therebetween, a passage opening, a replaceable nozzle part is fixed in said opening. of passage. In an advantageous embodiment, the nozzle piece is a tubular piece comprising a collar and an inner surface having a curved shape, which allows the smooth direction of air from the air supply chamber into the chamber. exhaust air and then, through the air discharge surface, into the room or other, u in the opposite direction. When a replaceable nozzle part is used, it is attached to the opening between the air supply chamber and the exhaust air chamber, so that the nozzle piece is attached to its collar. to be in connection with the opening. The nozzle pieces have different internal diameters D. The nozzle pieces therefore form a modular system comprising different internal diameters Di, D2, D3 ... Dn. When it is necessary to change the operating values of the air flow terminal device, it is only necessary to replace the nozzle piece located in the opening between the air supply chamber and the air chamber. venting, so that the desired operating range is achieved for the device. Thus, one and the same device can be used for different purposes, simply by replacing the nozzle part, and different operating ranges are obtained from a single device, simply by replacing the nozzle part. The cross-sectional force of the nozzle may also be other than a circular shape, for example it may be rectangular, and the collar may be joined to the unfinished tube portion. In one embodiment, the nozzle is an elongate slot nozzle.
    The air flow terminal device according to the invention is characterized by the features presented in the claims.
    In the following, the invention will be described with reference to certain advantageous embodiments of the invention, shown in the figures of the accompanying drawings, but there is no intention to restrict the invention to them only.
    Figures IA and IB show an air flow terminal device of the state of the art.
    FIG. 2A shows a terminal device for airflow according to the invention.
    Figure 2B is a cross-sectional view along line I-I of Figure 2A.
    Figure 3A shows different nozzle structures for the modular air flow terminal device of the invention. Thus, the air flow terminal device is a modular structure, the nozzles of which can be replaced when different ranges of operation of the air flow are desired for a single terminal air flow device without modify the structure.
    Figure 3B is a cross-sectional view along line II-II of Figure 3A.
    Figs. 1A and 1B show an air flow terminal device 10 of the state of the art. The feed air is conducted from a feed chamber using a discharge surface into a workpiece H. The structures shown in Figures 1A and 1B can not be modified in any way. Thus, when the device is placed in a system of air conditioning ducts, the device is chosen according to the object of use of the room. However, currently, the object of use of a part can change many times during its lifetime, and therefore the air conditioning must also be flexible and for example, it must be possible to modify the terminal devices according to the object of use.
    FIGS. 2A and 2B show a new type of air flow terminal device 10 according to the invention for driving air into a room or for driving air out of a room. The terminal device 10 comprises a chamber 11 and a conduit connection 11a therein, through which an airflow is directed from a conduit system into an interior space Si of the feed chamber 11, when the device functions as a terminal air supply device. The air flow terminal device 10 comprises, in addition to the feed chamber 11, also an evacuation chamber 12, and between them there is a partition wall 13 and therein an opening The airflow opening 14 is preferably a circular opening comprising a replaceable nozzle part 15 according to the invention. The nozzle piece 15 is a tubular piece comprising a collar 16. The collar 16 is connected on its inner surface ti with a curvature R, directly to a pipe wall t2 of a tubular part 17. Between the tubular piece 17 of the nozzle piece 15 and the collar piece 16, there is a curvature R. The curvature R is preferably (0.14 -0.19) x the internal diameter D of the pipe 17. The collar 16 comprises passage ni, n2, ... through which a fastening means, such as a screw Ri, R2, ... can be passed to connect the nozzle 15 removably to the wall 13 between the feed chamber 11 and the chamber evacuation 12.
    As shown by the arrows Li, the air is conducted from the supply line P (dashed lines) inside the feed chamber 11 in a space Si t thereof, by a nozzle piece 15. in the internal space S2 of the evacuation chamber 12, and then by an air discharge surface 18, in the room H. The direction of the air flow can also be opposite, when the device is used as an air evacuation device, namely the air is sucked from the room H into the evacuation chamber 12 and through the nozzle 15, into the supply chamber 11, then into an evacuation pipe of air. The air discharge surface 18 may be any type of air flow directing part, such as a perforated surface, fixed louvers, a surface formed by separate nozzles, and the like.
    If the object of use of the part H and modified and for example, the range of air flow rate must be modified, this is achieved according to the invention by replacing the nozzle part 15 between the chamber of air supply 11 and the exhaust air chamber 12. The nozzle part 15 is selected from a modular structure, namely, from a series of nozzles 100, so that the nozzle part 15 has a certain opening in cross section, such as a diameter Di or D2 or D3 ..., which will fill the desired range of airflow, the range of pressure rates, the range of noise levels, etc. Thus, the most appropriate nozzle can be chosen for the terminal device 10 among the nozzles 15 having different tube sizes Di, D2, D3, ...
    In FIGS. 2A, 2B, connection screws are indicated by R 3, R 2,... And using these screws, the nozzle piece 15 can be connected to its collar 16 on the wall 13. In addition, the chamber of FIG. air outlet 12 can be connected on its wall 13 by the screws Ei, E2, ... to the air supply chamber 11, on the edge fi of its housing-type chamber structure.
    FIG. 3A shows a modular structure formed by a series of nozzles 100 having different diameters Di, D2, ...
    Figure 3B is a cross-sectional view along the line II-II of Figure 3A. The nozzle 15 comprises a collar 16, whose radius of curvature R is 0.14-0.19 x D (D = the internal diameter of the tube 17). The nozzle 15 is attached with the screws Ri, R2, ... to a plate 13 of the evacuation chamber 12 in its opening 14, namely in the wall 13 between the supply chamber 11 and the evacuation chamber 12. The collar 16 extends into the evacuation chamber 12 and the tube 17 projects into the supply chamber 11.
