Definitions

  • the invention relates to a window blowing device for ventilation and air conditioning systems according to the preamble of claim 1.
  • Such a window blowing device is known from DE-OS 30 12 593.
  • a constant supply air volume flow is blown into the exhaust duct via the primary nozzles.
  • a second adjustable supply air volume flow is fed to the secondary chamber via a volume flow controller.
  • the supply air emerges from the secondary chamber via secondary outlets without a significant flow impulse and is carried away by the primary air jets by induction.
  • rimär Kunststoffstrahlen by the induction effect of P is space-5luft sucked via lateral entry openings.
  • the constant volume flow of the primary air jets determines the total amount of air carried by induction, which, depending on the setting of the secondary volume flow, is composed in a different ratio of the supply air of the secondary air flow and the circulated room air of the tertiary air flow.
  • the total volume flow blown out of the discharge shaft into the room is thus determined practically exclusively by the volume flow and the flow velocity of the primary air jets and their induction effect. Since the volume flow and thus also the flow velocity of the primary air jets remain constant, the total volume flow and the flow velocity of the air emerging from the discharge duct also remain constant. These values can therefore be set to the optimum value for room ventilation and purging. Nevertheless, by changing the ratio of the supply air secondary volume flow to the room air tertiary volume flow, the total ratio of supply air to room air in the volume flow emerging from the discharge duct can be adapted to the current cooling or heating load for air conditioning the room.
  • the known window blowing device is complex to construct, since the supply air is supplied to the primary chamber and the secondary chamber via separate lines. Two separate servomotors are also required. With one, the total supply air volume that the window Blower is supplied while the second servomotor sets a volume flow controller in the supply air line feeding the secondary chamber.
  • the invention has for its object to improve a window blowing device of the type mentioned so that it is structurally simpler and cheaper to manufacture with the same advantageous functionality.
  • the supply air to the primary chamber and the secondary chamber is not supplied separately. Only a single supply air line is provided through which the supply air is supplied to the primary chamber.
  • the supply air enters the secondary chamber from the primary chamber, the passage cross section being adjustable in order to be able to vary the secondary volume flow in the desired manner.
  • variable supply air exiting from the primary nozzle P rimärvolumenstrom is in the primary chamber feeding a supply air volume flow regulator is puts.
  • the volume of supply air supplied to the primary chamber is increased by means of this volume flow controller so that the volume flow emerging from the primary nozzles remains constant.
  • a common sheet metal housing which extends in the longitudinal direction of the blow-out shaft and is divided into the primary chamber and the secondary chamber by a partition.
  • openings are distributed over its longitudinal extent, through which the supply air flows from the primary chamber into the secondary chamber, evenly distributed over the entire length.
  • a slider on the partition allows simple and uniform adjustment of the passage cross-section for all openings.
  • the supply air line feeding the primary chamber is expediently provided.
  • Volume flow controller and the slit valve operated by a common servomotor.
  • this has the advantage in terms of production costs that only a single servomotor is required, and on the other hand, this results in an inevitable coupling of the setting of the supply air volume flow and the supply to the primary chamber of the secondary volume flow entering the secondary chamber from the primary chamber.
  • the adjustment of the volume flow controller and slider slide necessary for the required constant maintenance of the volume flow emerging from the primary nozzles is thus automatically achieved in a particularly simple manner.
  • a supply air duct 1 which may optionally have a post-heater 2, the supply air from the channel system of ventilation or air-conditioning the F ensterblas réelle is supplied.
  • a volume flow controller 3 known per se is inserted into the supply air line 1. The volume flow controller 3 is actuated by a servomotor 4 controlled, for example, by a thermostat.
  • the supply air line 1 opens into a primary chamber 5, which extends over the entire length of the window blowing device, i.e. the width of the window.
  • a secondary chamber 6 connects to the side of the primary chamber 5 and parallel to it.
  • the primary chamber 5 and the secondary chamber 6 are formed by a common sheet metal housing and separated from one another by a partition 7.
  • Openings 8 are provided in the partition 7, which allow the supply air to pass through from the primary chamber 5 into the secondary chamber 6.
  • the openings 8 are rectangular and distributed at equal intervals over the longitudinal extent of the partition 7.
  • a slit slide 9 which can be displaced in the direction of the longitudinal extent of the dividing wall 7.
  • the slide valve 9 has openings 8 corresponding to the openings.
  • the slit slide 9 is between a position in which its openings coincide with the openings 8 of the partition 7 and release them completely, and a position in which its openings are each between the openings 8 of the partition 7, so that they are completely closed , slidable.
  • the slit slide 9 is connected to the servomotor 4 via a rod and is displaced by the latter.
  • primary nozzles 10 are provided which are distributed in two rows over the entire longitudinal extent of the window blowing device.
  • the width and the opening cross section of the primary nozzles 10 are dimensioned such that the supply air from the primary chamber 5 in the form of primary air jets is blown into a mixing chamber 11 arranged above the sheet metal housing of the primary chamber 5 and the secondary chamber 6.
  • a secondary outlet 12 is provided in the form of a slot which extends over the entire longitudinal extent.
  • the mixing chamber 11 narrows upwards into a vertical blow-out duct 13.
  • the secondary outlet 12 is through a vertical, which expands over the entire longitudinal extent of guide plate of the primary nozzles 10 are separated, so that the coming out of the secondary outlet 12 air supply to until immediately prior to entering the mixing chamber 11 usblasschacht in the A 13 with the emerging from the primary nozzles 10 the primary air jets combined.
  • the supply air is discharged from the primary chamber 5 with a relatively high speed in the form of primary air jets and is usblasschacht through the mixing chamber 11 in the A blown. 13 Because of the large opening cross-section of the secondary outlet 12, which is designed as a continuous slot, the supply air from the secondary chamber 6 only passes through the secondary outlet 12 into the mixing chamber 11 at a very low, low flow rate and is essentially carried along only by the induction effect of the primary air jets. Next rimärluftstrahlen room air is drawn in via the inlet openings 14 and taken into the Ausblasschacht 13 by the induction effect of the P.
  • the volume flow and the flow rate through the primary nozzle 10 into the mixing chamber 11 and the rimär Kunststoffstrahlen Ausblasschacht 13 blown P determine the total entrained by induction air quantity. If the volume flow and flow rate of the primary air are kept constant, the total amount of air entrained by induction also remains constant and a constant total volume flow is blown out of the blow-out duct 13 at a constant flow rate.
  • the tertiary room air volume flow sucked in via the inlet openings 14 decreases accordingly, since the overall induction effect of the primary air jets remains constant. Conversely, if the secondary volume flow is reduced, the tertiary volume flow increases.
  • the volume flow controller 3 is inevitably operated together with the displacement of the slit slide 9. If the passage cross-section between the primary chamber 5 and the secondary chamber 6 and thus the secondary volume flow is increased by moving the slit slide 9, the volume of supply air supplied to the primary chamber 5 is increased simultaneously by the volume flow controller 3.
