Definitions

  • the invention describes an arrangement for an air outlet with fan for preferential use as Zu povertyauslass in ventilation systems for buildings with Zu povertyverteilsystemen that are installed under the rooms to be supplied.
  • supply air outlets are used in building ventilation systems for introducing the supply air into the room.
  • the air is first processed in the ventilation units accordingly (by filtering, thermal conditioning, compression, etc.) and then transported via Zubuchverteilsysteme to the outlets.
  • the supply air leaves the ventilation system and is distributed depending on the ventilation design and adjustment of the supply air outlets in the room.
  • Ventilation systems for large-volume rooms especially in department stores, open-plan offices, railway stations, airports are normally designed so that here the central unit of the ventilation system is positioned in the roof area. There, the conditioning of the fresh outside air or the exhaust air takes place.
  • the treated supply air then passes through roof openings to the room-specific adapted supply air distribution system, which is normally located in the ceiling area.
  • the supply air outlets are then connected to the distribution system so that the air can be introduced at the desired locations in the room.
  • the ventilation unit is preceded by, for example, a geothermal heat exchanger, which proportionally assumes the conditioning of the fresh outside air.
  • a geothermal heat exchanger which proportionally assumes the conditioning of the fresh outside air.
  • the positioning of the supply air distribution system can also take place underneath the floor.
  • thermal losses can be further reduced, especially since the supply air is then already at the level of the supply level.
  • the technical design matching air outlets which are preferably designed in the form of Bodenauslässen, then receives a special meaning.
  • the aim of the arrangement according to the invention is to describe a universally applicable air passage, with the aid of an energetically optimizable supply air distribution in space is possible.
  • the invention has for its object to describe an arrangement for an air passage for preferential use as Zu povertyauslass in the form of a floor outlet, characterized in that the supply air connection to a Zu povertyverteilsystem via a universally shaped connector consisting of an adapter piece, which on the one hand the connection to the Air distribution system manufactures and on the other hand ensures the hygienic safe transition over the bottom or the openings and an asymmetric transition piece through which a structurally easy to produce transition to the ventilation components of Zu povertyausltru can be made.
  • the supply air is passed through a filter assembly with replaceable filter material.
  • a filter assembly with replaceable filter material.
  • the technical design of the filter is designed so that the degree of filtering effect can be monitored by means of sensors.
  • a fault message may be generated requesting the replacement of the filter material.
  • the filter assembly in cassette format is designed so that exchanged via an adapted closure mechanism, the filter material can be.
  • volumetric flow controller Via a subsequently positioned volumetric flow controller, a variable adaptation of the pressure conditions to the set volumetric flow of the outlet can take place.
  • the mechanical adjustment of the regulating flap takes place via an electromechanical drive, which receives its actuating information from a central control device.
  • the use of the volumetric flow controller thus forms the prerequisite for variable operation of the supply air outlets. Due to its possible operating modes, it is thus possible to operate only a certain number of decentralized outlets independently of each other, with the objective to operate on the one hand ventilation systems with a needs-based mode of operation and on the other hand, the situatively necessary or desired supply air distribution to the to adapt to spatial requirements.
  • One or more fans are then connected to the volumetric flow regulator with the task of optimizing air distribution at the location of the supply air outlet.
  • Directly driven, speed-controlled radial, axial or tangential fans with electric motors in the preferred EC version are used here.
  • these fans are normally operated in series together with a supply air fan in the ventilation control center, which supplies the supply air distribution system.
  • This interaction of the series connection of the supply air fan in the central ventilation unit with the decentralized fans in the decentralized supply air outlets ensures energy-efficient operation for the entire air transport at all times.
  • the required volume flow at the location of the decentralized supply air outlet can thus be ensured, taking into account an always efficient mode of operation.
  • an adapted silencer can be used on the fan to compensate for disturbing noise levels in the vicinity of the air outlet. Subsequently, the supply air then enters the interior of the outlet housing. Here, the pressure adjustment takes place to the necessary outlet volume flow.
  • a solution is preferably provided as source air outlet for the ventilation-technical form of Zu Kunststoffauslasses.
  • the mechanical structure and the geometric shape of the outlet housing forms another possibility for a variable use, the arrangement described here.
  • floor outlets which can be placed in the middle of the room, there is also the possibility of the outlet housing to components of the building, for example, to Tragchulenkonstrutationen and adapt walls.
  • the outlet housing can be physically and constructively adapt.
  • the advantages of the arrangement according to the invention consist in the fact that it can be used to design ventilation systems that can operate a number of decentralized Zu Kunststoffauslässen as needed and depending on the requirements of the user. Depending on the operating situation, it is ensured that both the air transport to the outlet and the local air distribution take place under optimal energy criteria. Due to the variable structure of the arrangement for the Zu Kunststoffauslass this can be adapted to existing components of the building or existing fittings in the room.
  • FIG. 1 An embodiment of the inventive arrangement is in FIG. 1 and will be described in more detail below.
  • FIG. 1 an exemplary scheme for a Zuluftauslass with fan in the form of a bottom outlet with source air function.
  • An air supply connection to the supply air outlet is made via a floor opening (4), which is equipped with an adapter piece (2), to a supply air distribution system (1) laid under the concrete floor (3).
  • a supply air distribution system (1) laid under the concrete floor (3).
  • an asymmetrical transition piece (5) the detachable connection of the arrangement to the structure (3) or to the outlet housing (10) takes place and, on the other hand, dimensional deviations between the center axis of the bottom opening and the inlet air outlet can be compensated.
  • the air filter (6) with exchangeable filter material cleans the incoming air of suspended matter.
  • a volumetric flow controller (7) arranged to adjust the necessary pressure losses at different operating settings.
  • a speed-controlled fan (8) with adapted muffler (9) forms the conclusion of the active part of the arrangement. From the muffler (9), the supply air flows into the interior of the outlet housing (13) and from there via the outlet openings (14) into the room.
  • a BUS system (16) is provided which forms the interactive connection to the control module (15) in Zu Kunststoffauslass. Pressure-evaluating sensors monitor the filter assembly (6). The control of the mechanical drive and evaluation of the sensors of the volume flow controller (7) via corresponding leads (19). The power supply, speed control, speed and fault monitoring (20) for the fan (8) also takes place via the control module (15).
