Definitions

  • the invention relates to a control and / or regulating unit for metering an air flow, with a housing having at least one air duct.
  • the invention relates to a ventilation system.
  • Control and / or regulating units of the type mentioned are known from the prior art. They serve to dose or adjust the volume flow or the volume of an air flow.
  • the use of such a control and / or regulating unit is particularly important in ventilation systems in which a plurality of air streams are branched off from a main air flow in terms of flow. By the successive branching creates a pressure drop in the flow direction, which leads to the fact that the flow laterally branched off air flows have a lower volume flow than the first branched air streams.
  • This problem is solved in that the air streams are assigned a control and / or regulating unit of the type mentioned above, wherein the respective air flow is metered by the control and / or regulating unit such that all air streams have substantially the same volume flow.
  • Such a control and / or regulating unit generally comprises at least one air channel, which passes through a housing or the control and / or regulating unit.
  • the housing is made of sheet metal, which leads to high production costs and high production costs.
  • such a control and / or regulating unit has a high weight.
  • the invention has for its object to provide a control and / or regulating unit for metering an air flow, which avoids the disadvantages mentioned above.
  • the housing is formed of expanded homopolymer.
  • Expanded homopolymer or also called expanded Unipolymerisat is a foam-like material, which is particularly light, yet very stable, so that a control and / or regulating unit with a housing formed from expanded homopolymer is particularly easy, the housing a to the shoring or Assembly has necessary stability.
  • the manufacturing costs are relatively low, since on the one hand the housing of the expanded homopolymer due to the manufacturing process does not have to be reworked or only slightly, and on the other hand, the manufacturing process requires a relatively low cost.
  • the elasticity of the expanded homopolymer also allows the simple installation of the control unit and / or a simple attachment of a the air flow of the control and / or regulating unit supplying or from the air flow from the control and / or regulating unit laxative air line.
  • the air line in a corresponding receiving opening of the housing can be inserted, wherein due to the choice of materials in a simple manner on the one hand a positive and positive connection and on the other hand, a seal between the air line and the housing can be produced.
  • the expanded homopolymer is preferably expanded propylene, in particular with a density of about 60 g / l.
  • polypropylene also called polypropene, is a semi-crystalline thermoplastic and is obtained by polymerization of the monomer propyl with the aid of catalysts. It is resistant to almost all organic solvents and fats, as well as most acids and alkalis, so that even with a long-lasting use of the control and / or regulating unit, for example in a ventilation system, the function and the integrity of the housing is permanently guaranteed.
  • Expanded polypropylene is a particle foam based on polypropylene.
  • two principal methods are known: the autoclave technique and the direct foam extrusion.
  • the expanded polypropylene has a density of about 60 g / l (RG60).
  • the expanded homopolymer is expanded polystyrene.
  • Polystyrene is a transparent, amorphous or semi-crystalline thermoplastic. It is obtained by polymerization of the monomer styrene, which has exceptional polymerization properties and can be fully recycled.
  • Foamy or expanded polystyrene which has become known under the name Styrofoam, has a high compressive strength and a low water absorption capacity.
  • the expanded polystyrene is very good machinable with a thermosaw, so that the processing of the housing of the control and / or regulating unit is very simple and inexpensive. The production of the housing is also very inexpensive.
  • the air channel is formed by the housing. It is therefore intended that the housing is designed such that it forms the air duct directly. Due to the advantageous Choice of the material of the housing, this is possible in a simple manner.
  • the housing is designed in several parts. This means that the housing does not have to be manufactured in one piece, but has several parts, which are assembled according to the respective production.
  • the housing is formed by two identical housing shells.
  • This has the advantage that for the production of the housing, only a basic shape is necessary, in which a housing shell is made or urgeformt.
  • the housing is then formed.

  • the air duct has a substantially circular cross-section, which leads to flow advantages. Due to the identical design of the housing shells, the air duct is expediently formed in equal parts of each housing shell, so that the recess or recess in the identical housing shells are formed substantially semicircular.
  • Such identical housing shells are also referred to as turning shells. In the manufacture of the housing, this leads to the advantage that no complicated shapes must be used. Due to the identical design of the housing shells, which in particular form the air duct in each case up to a plane of symmetry of the air duct and preferably also of the housing, a simple demolding of the housing shells is made possible.
  • the housing shells as connecting means in each case at least one groove and at least one spring for forming a tongue and groove connection.
  • the groove and the spring are in this case aligned / arranged on the respective housing shell or on the identical housing shells such that when the housing shells are assembled the spring engages in the groove.
  • a frictional connection is thus made possible in a simple manner, which holds the housing shells together.
  • a tongue and groove connection of course, other compounds are conceivable, such as a pin-hole connection.
  • the spring is formed integrally with the corresponding housing shell.
  • At least two air ducts carrying the air flow are formed in the housing. So there are several air channels provided, which lead the one air flow.
  • the air ducts divide the air flow into partial air flows, which are expediently brought together again before leaving the housing of the control and / or regulating unit, so that the division of the air flow and the partial air flows and their combination takes place inside the housing.

  • the air channels are formed substantially parallel to each other.
  • a fixed volume flow limiter is arranged in the or in at least one of the air ducts.
  • This volume flow limiter is thus fixed, so that the air flow flowing through this air duct always experiences the same volume flow limitation.

  • an adjustable volumetric flow limiter is arranged in one or at least one other air duct of the at least two air ducts.

  • volume flow limiters in particular both volume flow limiters, are designed as volume flow limiting flaps.
  • volume flow limiting flaps are mounted in the housing, wherein the adjustable volume flow limiting flap is rotatably mounted.

  • the drive is either manually, so controlled by a user, or automatically, for example by responding to changing environmental conditions.
  • the drive is assigned a temperature, humidity and / or CO 2 sensor, which is arranged in a space to be ventilated.
  • Registered a control unit of the drive by means of the sensor that in the room is too low or too high a temperature, humidity and / or CO 2 concentration, the drive is controlled accordingly or the volume flow limiters adjusted accordingly, so that a desired air condition in the zu ventilated room is set or adjusted.
  • the housing has at least one, in particular two access openings. These serve to gain access to the housing or to the air ducts located in the housing, for example for cleaning purposes.
  • one of the inspection openings is arranged upstream of the volumetric flow limiter or the division of the volumetric flow and another downstream of the volumetric flow limiter or the merging of the partial air flows.
  • a so-called pig is used, which is formed cleaning ball-like and is advantageously impregnated with a corresponding cleaning liquid. This is introduced through one of the inspection openings in the housing and pressed there by means of the existing air flow through the air channels and / or sucked. Since the volume flow limiters are an obstacle for this pig, the inspection openings are advantageously arranged upstream or downstream of the volume flow limiters, as already stated.
