Definitions

  • the invention relates to a method for dimensioning and planning of fresh water distribution systems in buildings with a plurality of consumers and a pressure-independent flow regulator or volume-controlled jet regulator for use in such a method.
  • the local flow regulator has a control core insert, comprising a support ring and a control core connected to webs.
  • U- rectangular or semi-circular grooves are recessed, between which lie substantially flat lateral surfaces.
  • An O-ring can then come in line, but also over a large area with the mantle surfaces in contact.
  • the for the fluid medium, especially water, open cross-sections in the grooves and thus the flow rate is precisely defined and reproducible.
  • jet regulators or jet shapers which are offered by Neoperl GmbH under the brand name "Neoperl®” or “Perlator®", are state of the art.
  • Such jet regulators or jet shapers may have an integrated flow regulator whose operating principle is based on the fact that an elastically deformable element more or less closes or releases a passage gap for the fluid medium, depending on the prevailing pressure conditions.
  • the corresponding sanitary installation device has for this purpose a continuous coding, which contains information on the installed parts. Furthermore, a recording device is provided with which the coding is readable.
  • the pipe sections, rods or fittings used are preferably already provided in the production with a continuous coding according to the teaching there, which contains, for example, the nature of the pipe section or the connecting rod and which is arranged at fixed intervals.
  • the coding is attached, for example, only on elongated connection points, ie on the pipe sections or connecting rods.
  • the fittings are identified indirectly via the pipe sections or connecting rods.
  • On the necessary recorder then only the type of connection part, so for example a plastic fitting, must be entered.
  • a bill of material is then created, which, coupled with a product database, enables the exact billing of the installed sanitary pipe system.
  • the coding according to EP 1 308 563 A2 preferably consists of a bar code, which can be identified with an optical reader and which is printed, for example, on the outside of the coded parts. Also, the coding can be spiraling on the coded parts be applied to create a reading opportunity in any position. However, the barcode or barcode can only be identified with a special reader, but not by simple inspection, and the information content hidden in the code can be recognized.
  • Essential to the invention is also the use of pressure-independent quantity regulators or jet regulators, which have such a flow regulator, according to the teaching Claim 8.
  • a basic idea of the invention lies in the fact that in the planning and execution of sanitary facilities basically only sanitary components are to be used at the consumption points, which have separate or integrated flow regulator. With stringent pursuit of this basic idea, the dimensioning of complex building installations for fresh water distribution systems is simpler, since the pressure fluctuations which usually arise during operation and can not be influenced can largely be disregarded.

  • the product identification certificate contains information on the water flow rate or the water flow rate range in the form of an encoding, in particular a color coding.
  • This color coding can about it Be used as a synonym for energy efficiency, for example, the color green for a desired and desired consumption reduction, ie, a lower flow rate, for example, for use in a hand basin.
  • the number and type of future consumption points is determined in dimensioning and planning of fresh water distribution systems in buildings with a large number of consumers in a first step.
  • a fixed volume e.g. Washing machine or cistern
  • a defined water flow rate e.g. a shower is.
  • Each water flow rate or each water flow rate range is assigned a coding, in particular a color coding, which is unique.
  • At least information about a desired flow rate of the respective quantity regulator and the installation dimensions for the advantageous field of application can be taken from the product identification certificate.
  • the outlets which are used in domestic installations, added to a pack information or it has such an indication, which indicates an optimal interaction with a pressure-independent flow regulator, preferably for this also a color coding is used, which corresponds to the water flow rate coding, so that the correct, preferred combination flow regulator / outlet fitting results solely from the assignment color to color.
  • a classification can be made on the basis of the achieved efficiency classes. This classification, in turn, is preferably taken into account in the consumption fee determination. Likewise, the efficiency class of the fresh water distribution system can be used with legally required house energy pass.
  • Efficiency class is to be understood as a classification or assessment which is not limited to the water and thus the indirect Energy consumption oriented, but also the noise, due to the flowing medium includes.
  • the respective efficiency class also provides an indication of the extent to which CO 2 emissions can be reduced if the production of hot water is based on the use of fossil fuels.
  • the sanitary component proposed for use in the implementation of the method according to the invention is a quantity regulator or a volume-controlled jet regulator.
  • the jet regulator or jet former for fluid media consists of property-determining components which are sandwiched in the flow direction. These comprise at least one attachment screen, a Zerlegerplattenan extract and a sleeve body extending over its cross-sectional area, beam-forming, perforations having segments, to achieve adaptability to a variety of user and application requirements, the property-determining components are interchangeable and combinable and this on or in the sleeve body fastener and arranged on the Zerlegerplattenan angel corresponding fasteners, preferably molded or molded.
  • the Zerlegerplattenan Aunt has at least on the outside a flow class specifying and the sleeve body a the flow type, namely laminar or air enriched, specifying optical encoding.
  • the front screen is preferably designed to be translucent or preferably transparent.
  • the flow regulator itself may have a further optical coding.
  • optical codings are designed as different color codings.
  • the color gradations or color differences of the respective codings can include color temperatures which can be visually detected by means of optoelectronic image acquisition and evaluation as well as without aids.
  • the flow regulator has the control gap mentioned in the introduction, the flow cross-section of which is variable by means of an elastically deformable under the pressure of the fluid flowing medium element, in particular ring, wherein the transparent or translucent properties of the attachment screen are selected so that the flow regulator itself and the position of the deformable ring or the elastic element can be seen ,
  • the elastic element or the elastic ring itself have an optical coding, in particular a color coding, which is in color contrast to the control gap or its bypass.
  • the use of sanitary components designed in this way takes place on the basis of a code table authorized by the manufacturer, which indicates which optical coding of the components recognizable without dismantling corresponds to the respective application with respect to jet shape, flow rate limitation and / or flow class or approaches this application to a large extent.
