Type of article DESIGN APPLICATIONS
Content up-to-date for version GOLD Rev. 15.3


Scope of lesson

The article presents how to design internal sanitary systems (hot, cold water, hot water circulation piping). The example is based on a project prepared for a three-storey unifamilar house with a basement.

Modules and program configuration

  • InstalSystem 5 with the module:
    • Tap water systems

Initial state

The project contains complete default data configured in the template file. The building structure has been elaborated on the basis of DWG layouts.

Steps to perform

Opening the project file

  1. Open a new project.
    For more information, see: Project and application management
  2. Choose the required template file (optional).
    For more information, see: Template files
  3. (alternatively): Open an existent file with a building structure. If it has been prepared with a different package configuration, import general data and settings from the template.
    For more information, see: Template files

defining catalogues and general data

Correction of general data is not necessary if we begin work with a template file dedicated to such a scope. Correction is necessary if we begin work with a file that has been elaborated with a configuration without tap water systems module.

  1. Project scope - define project scope: Water supply systems.
  2. Catalogues – choose catalogues according to the list in the project table in scope of:
    • pipes and fittings,
    • insulation,
    • tap assemblies and water outlet points,
    • valves and fixtures.
  3. Water supply systems:
    • Calculation standards and options:
      • Calculation standard - choose the correct norm indicating method of flow calculation,
    • Sources
      • Default building type
      • Default cold water temp.
      • Default hot water temp.
    • Distribution system
      • Types and default data
        • Default pipe types: Cold water pipe-runs
        • Default pipe types: Hot water and circulation pipe-runs
        • Default valve types
        • Default types of fittings and manifolds
      • Pipe and insulation sizing options
    • Fixtures and water outlet points
      • Domyślne przybory sanitarne i domyślne dla nich punkty czerpalne
      • Default connection systems
        • System of water outlet points connections - according to the applied pipe system

Editing sanitary installation

Perform inserting and graphical edition with AUTO mode on (for chosen layers).

Fixtures and water taps

  1. Select the Water main editing scope.
  2. Insert fixtures and water taps in proper rooms.
    1. Fixtures and water taps

Source

  1. Insert Source and configure it in scope of:
    • Connections
    • Source appearance
      2. Source

Riser

  1. Insert Riser and configure it in scope of:
    • Symbol
    • Connections
      3. Riser

Heater

  1. Insert Heater and configure it in scope of:
    • Symbol
    • Water heater type
    • Circulation connection
      4. Heater

Installation distribution

Connect the inserted elements by various pipe feeds with correct spacing between them, using the AUTO and ORTO working modes.
Circulating piping should be connected hot water pipe feeds at the water outlet points by drawing circulating pipe feeds from the riser peak.
5. Installation distribution


Connect water outlet points with the water distribution installation with the Automatically connect terminal units function.

Valves

  1. Insert Non-return, shut-off and ball valves, Backflow preventers, Circulation controller, Pressure reductor/controller.
    Valves may be moved in 3D view vertically on vertical sections if needed. In addition, while changing Rotation angle in Tabeli danych, it is possible to rotate valves about the pipe feed axis.
    6. Valves

Fittings

  1. Insert Filters, Water meter.
    Fittings may be moved in 3D view vertically on vertical sections, if needed. In addition, while changing Rotation angle in Tabeli danych, it is possible to rotate valves about the pipe feed axis.
    7. Fittings

Safety valve

  1. Insert Safety valve and connect it with the installation via the No medium flow pipe feed type.
    8. Safety valve

Installation structure correctness verification

  1. Verify correctness of the installation structure with the Check connections function (shortcut: Shift + F2).
  2. Verify correctness of the installation structure and detect collisions with3D view.
    9. Installation structure correctness verification


    For more information, see: Verification of the correctness of installation structure

Editing data of installation elements

Fixtures and water taps

  1. Correct Distance from floor, if necessary
  2. Correct Demand type, if necessary
  3. Correct / completeSystem of water outlet points connections
    10. System of water outlet points connections

Source

  1. Correct Source elevation, if necessary
  2. Enter Avail. press. if pressure in the external water supply system is known.

Heater

  1. Correct Distance from floor if necessary
  2. Complete Type of hydraulic resistance,
  3. Complete Source flow pressure drop for circ.

Calculations and diagnostics

  1. Run the Water supply systems calculations by clicking on the Tap-water-Calculator.png icon located in the Calculations section on the toolbar.
  2. Verify calculation results, in particular:
    • selected supply pressure and obtained available pressure at receptors,
      11. Receptor

    • calculations of circulation circuits and their balancing,
      12. Circulation circuits

    • calculation of pressure booster circuit and pressure regulator parameters.
