Definitions
- the invention relates to an air outlet for ventilation systems for ventilation of rooms, especially hall-like rooms, which is arranged at the outlet of an air supply duct and at least one propellant jet and at least one an exit field adjacent to the driving nozzle for Has drag air, the propellant nozzle and the exit field are supplied with supply air from the air supply duct.
- the invention has for its object an air outlet to improve the type described above.
- the advantage of the air outlet according to the invention is that by a definite distribution of the air flow to the Exit field and the driving nozzle the jet characteristic of the air entering the room to the conditions of the room can be adjusted. It is influenced by the means the air flow the difference between the flow velocities of the propulsion jet and that from the exit field escaping towing air a dynamic pressure drop generated at the outlet. This causes drag air is pulled along by the propulsion jet and "encased" it, so that the kinetic energy of the propulsion jet is practically complete available for the transport of the tow air stands.
- the means of influencing the air flow in the air duct must be permanently installed, is provided in a development of the invention that the means for influencing the air flow are adjustable are trained.
- the air outlet can thus change Space, such as conversions or retrofits Internals to be adjusted without the ventilation system to have to rebuild in this area.
- An embodiment of the invention is achieved in that the means for influencing the air flow at least one Have flow dividers through which the amount of air the propellant nozzle and the exit field is divided.
- the Flow divider makes it possible to use the jet stream Air a larger or smaller area of the air supply duct to remove and according to the exit field to supply a smaller or larger amount of air, in total constant air volumes.
- the agent to influence the air flow by at least one at least the throttle device upstream of the outlet field educated can depend on the respective flow velocities the amount of air fed to the propellant nozzle and the outlet field Influenced, and so the distribution of air quantities be specified by the propellant nozzle and by the exit field.
- the penetration resistance is determined so that the Difference in pressure between the faster flowing drift jet and the slowly flowing drag air on the room side of the air outlet sucking in the drag air around the Driving jet causes.
- the throttle device can do so be specified that turbulence in the propellant jet avoided become. This makes it possible, in particular, a low-noise To reach air discharge.
- the throttle device at least two across in Direction of air flow and preferably at a distance from one another arranged perforated plates.
- the perforated plates represent a flow resistance, the free Passage cross section determined by the area of all holes becomes.
- the perforated plates are preferably at a distance from one another arranged so that the air flow through the perforated plates is essentially turbulent. The turbulence is causing a loss of speed energy.
- the perforated plates are preferably provided in the area in front of the exit field, so that a substantially lossless air flow can be done through the propellant nozzle.
- this air outlet two are identical Perforated plates are provided, which are adjacent to one another or at a distance to each other, transverse to the direction of the air flow and one behind the other are arranged. By moving the perforated plates the resistance to each other can be changed. Furthermore, it is possible that one of the perforated plates Part of the outlet field is what the construction of the air outlet simplified.
- the means of influencing the air flow several relative lamellar flow guide elements that can be pivoted relative to one another for directing and / or inhibiting the air flow.
- This enables the lamellar flow guide elements essentially perpendicular to the flow direction of the Align air in the air supply duct, making it easier Flow resistance reduce the flow velocity.
- the flow control elements with their surface in adjusted at an angle to the flow direction is achieved that the supply air in the air supply duct corresponds to the angle setting the flow control elements in the area as required the propellant nozzle or the exit field is directed. Consequently in addition to increasing the penetration resistance Flow division achieved with the desired difference between the air flow through the propellant nozzle and through the Exit field are adjustable. It is particularly useful if several lamellar flow control elements individually and / or in groups at their angle to the direction of flow are adjustable.
- the air outlet is expediently designed so that the funds for influencing the air flow as a cassette in the air supply duct can be pushed in and pulled out. So are Adjustments to special space requirements or repairs possible.
- Another advantageous embodiment of the invention has aligned at an angle to the axis of the motive air duct Exit field, which is also a shield against which forms indoor air. This is a disruptive access of room air into the jet directly at the air outlet largely prevented.
- the propellant nozzle into the air supply duct against the direction of flow the air-projecting pre-channel is assigned.
- the blowing nozzle becomes an essentially undisturbed air flow fed by the pre-channel to interference by redirecting to the exit field and by guiding elements in the Area of the exit field is shielded. This ensures that there is a "clean" undisturbed propulsion jet can train.
- the pre-channel at its entrance with pivotable relative to each other lamellar flow control elements for Change the air passage is provided. So that's it possible, independently or depending on the inflow of air to the propellant nozzle and to the outlet field.
- Air outlet is a final component 1 designed for an outlet on an air supply duct 2.
- the air outlet 1 is essentially formed from a plurality of driving nozzles 3 for generating driving jets can be pivotally mounted so that the beam axis 7 of the each generated driving jet adjustable in its angular position is.
- the driving nozzle 3 is an exit field 4 for Drag air assigned, for example through a perforated plate is formed and that in the illustrated embodiment located above the level of the driving nozzles 3.
- the perforated plate is shown schematically by the Cross hatching shown.
- the exit field 4 is here designed so that its surface is not only above the Ejection nozzles 3 but also clearly on both sides extends into the room. Now becomes the air supply duct 2 to the supply air, part of this occurs Air through the propellant nozzles 3 in the form of several propellant jets in the room. The other part of the air is over that Exit field introduced into the room.
- the passage cross sections the propelling nozzles on the one hand and the total cross-section of the passage the exit field 4 on the other hand and the corresponding Flow resistances of the driving nozzles 3 on the one hand and the exit field 4 on the other hand are so on top of each other matched that the flow velocity of the driving jets in The area of the nozzle mouth is about two to five times as high like the drag air emerging from the exit field 4.
- Such an air outlet 1 is in the room to be ventilated at an appropriate distance above the floor at a ventilated workshop, for example at a height of over 3 m, introduced into the room.
- a shield 5 for example in the form of a cover plate, covered, so that primarily from the Exit field 4 towing air emerging from the propulsion jets is taken into the room.
- the driving jets can expand upwards and take almost exclusively Drag air from the exit field 4 with due to the drag air because of the relatively low Flow rate only to a small extent in the room air introduced air is mixed in this way.
- the speeds can be set so that the Arrangement like a source ventilation works.
- a Air flow velocity in the propulsive jets of for example 5 to 20 m / sec and a flow rate the drag air of 1 to 4 m / sec respectively measured in the exit plane, the result is isothermal Operation an average speed of the supply air at a distance of about 5 m from the relevant exit surface the air outlet from about 30 to 120 cm / sec.
- the Drag air is emitted from the propulsive jets into the room carried in.
- cold air is fed into the room it can be useful, as indicated in Fig. 1, by pivoting the jet axis 7 of the driving nozzle 3 upwards Drag air into the room to "carry" the cold air to be carried as far as possible into the room so that the supply air can ultimately sink to the ground over a large area.
- Influencing the "beam characteristics" of the in the room escaping air by swiveling the driving nozzles 3 is often not sufficient because the distribution of air volumes predetermined by the dimensioning of the exit field 4 is.
- the ratio of the flow velocities of the exit field 4 and the driving nozzles 3 and thus each passing through these two areas of the air outlet Air volumes can by a means 6 to influence the Air flow in the air supply duct 2, here in the form of a flow divider 6.1 be set, which is practically over extends the entire width of the air supply duct 2.
- Flow divider 6.1 is pivotally mounted and can be in the direction the arrow is pivoted and in any desired angular position be determined.
- the air flow in the air supply duct 2 is divided and divided the outlet field 4 and the driving nozzles 3 distributed.
- the amount of partial air changes through the propulsion nozzles 3 is passed, as well as the flow rate in each case in relation to the partial air volume and the flow rate at exit field 4.
- the "zero position" of the flow divider 6.1 is given if it is aligned parallel to the longitudinal axis of the air supply duct 2 is. In the angular position of the flow divider shown the air flow is based on a substantial part the propellant nozzle is guided and accelerated. By Turbulence behind the flow divider 6.1 in front of the exit field 4 the air flow is braked in this area. This leads to the propellant jet emerging from the exit field 4 extracted drag air can carry further into the room. Becomes the flow divider 6.1 is pivoted in the opposite direction, then is a small amount of air in the room through the propulsive jets entered with lower flow velocity, d. H. the "throw distance" is reduced.
- FIG. 3 shows an arrangement of an air outlet as in FIG. 1 shown.
- the air outlet is arranged in reverse, which is particularly high when warm air is supplied Hall is appropriate.
