CYPEFIRE Hydraulic Systems

Data entry

Free definition

• Defining the elements in the model and their characteristics by means of free entry in CYPEHVAC.
• System design in CYPEHVAC based on DXF-DWG, DWF templates or images (.jpeg, .jpg, .bmp, .wmf).

Importing BIM models

If the CYPEHVAC job is linked to a BIM project from the BIMserver.center platform, the following tasks can be carried out:

• Importing the model with the geometry of a building. This makes it possible to generate the layout of the building and to import the layout of the spaces and assign them a specific type, in order to subsequently enter the system elements (such as supply points and elements, water distribution networks and consumptions such as sprinklers, fire hose reels, emitters and wet riser outlets) based on this geometry. The following options are available:
  • Importing models designed in CYPE Architecture.
  • Importing models designed in IFC Builder. 
  • Importing models in IFC format (generated by CAD/BIM programs such as Allplan, ArchiCAD and others) uploaded to the BIMserver.center project via the web platform.
  • Importing models designed in Autodesk Revit with the Open BIM - Revit Plugin.
• Importing the layout of the fire hose reels and the inlet and/or outlet openings of dry and wet risers from the model, if these elements are available. This will subsequently assist in the insertion of these elements using the program's own options.
• Importing sprinkler installation requirements for spaces from the analysis results of the programs that define and validate fire protection systems:
  • Importing sprinkler installation requirements in spaces from models that have been analysed in CYPEFIRE.

Data output

• Exporting reports to HTML, DOCX, PDF, RTF and TXT formats.
• Exporting drawings to DXF, DWG and PDF formats.
• Exporting the bill of quantities to FIEBDC-3 format.
• Exporting the information generated with CYPEFIRE Hydraulic Systems to the BIMserver.center platform using IFC formats. This allows it to be viewed by authorised project participants.
  • CYPEFIRE FDS
    Imports the layout of the CYPEFIRE Hydraulic Systems sprinklers.

The CYPEFIRE Hydraulic Systems interface has three tabs with different working environments: "Installation", "Diagrams" and "Bill of quantities". Both environments are similar to those in other CYPE tools and have a system of dockable windows that can be customised to adapt the workspace to the project's needs.

"Installation" tab

The tab activated by default when getting started is the "Installation" tab. This presents a work environment that allows the installation's design to be carried out quickly and easily, both in a 3D view and in any type of 2D view (such as floor plans and elevations). This way, the installation elements can be entered using the most appropriate view at any given moment.

The tab shows:

• A top toolbar containing the tools for: managing the general characteristics of the project; entering and generating spaces; entering the supply points, the elements of the water distribution network and the consumptions (sprinklers, fire hose reels, emitters and wet riser outlets); defining the design loadcases; entering the seismic bracing; using the editing tools; and carrying out the analysis, checking and sizing of the installation.
• The modelling area, on the right side of the screen, where all the project elements are entered, edited and displayed.
• On the left-hand side, several panels with tools for defining the project views and for managing the visibility of the elements read and the own elements.

"Diagrams" tab

The "Diagrams" tab provides a working environment that can be used to compose fire extinguishing system diagrams on sheets in the desired formats.

This tab displays:

• A top toolbar containing the tools for entering the elements that make up the fire extinguishing system and configuring the display options.
• The workspace, on the right-hand side of the screen, where the system diagrams are entered, edited and displayed.
• On the left-hand side, a navigation panel between the different diagrams created, which are composed of editable format and scale sheets.

"Bill of quantities" tab

On the other hand, the "Bill of quantities" tab is used to manage the bill of quantities of the elements in the installation, and displays the following:

• A top toolbar where the tools for creating and editing the bill of quantities are located, as well as those for managing and creating reports.
• A graphic window with its own toolbar, located on the right-hand side, in which the different elements of the job can be displayed.
• On the left-hand side, is a specific area for structuring the bill of quantities.

When starting the program and clicking on "New", the program offers users the possibility to create a "New job", which can then be integrated into an existing project in BIMserver.center.

This is done in the "Project selection" window. On the left-hand side, you can log in with a BIMserver.center account.

• On the left-hand side, users can log in with a BIMserver.center account.
• On the right-hand side, the "Select project" option is used to choose an existing project. There is also the possibility to "Create a new project". In this case, the created project will be visible from BIMserver.centre from that moment on.
• The project can also be starting without being linked to the BIMserver.center platform. To do this, simply uncheck the box at the top left, "Link to a BIMserver.center project".

Once the new job has been created, the program interface is accessed, where the graphic window showing the model or models that have been imported stands out. At any time during the project, files can be shared or imported via the "BIMserver.center" group on the top right-hand side.

Importing BIM models

When creating a new job and selecting a project hosted on the BIMserver.center platform from "Select project", the "Import BIM models" window appears, which shows the files contained in that project in IFC format.

The program is able to include one or more of the existing models in the project. To do this, check the "Import" box and accept it.

When accessing the interface, the graphic window will display the imported models. Also, if they contain this information, the plan views needed to develop the system model will be imported and created.

Configuration wizard: selecting standards, downloading catalogues and classifying spaces

The program then opens the "Configuration" wizard, which consists of the following steps:

• In the first step, the applicable codes can be selected from those available for different countries and regions. The checks defined in the standard are then automatically imported.

• In the next step, the connection to the Open BIM Database can be established in order to download and manage manufacturer catalogues. These catalogues will be available at the time of entering the elements in the system.

• Finally, in the last step you can set the automatic classification of the spaces read from the project’s IFC file according to the specific typologies required by the program.
  To do this, entries must be added to the assignment table manually (using the "Add" button) or via the wizard.
  In each entry, the spaces to be classified are filtered by specifying the values of their properties (in the "Value" parameter), and the room typology defined by the program that you wish to assign to them is selected (by activating the "Requires sprinkler system" box and choosing a specific room typology). In addition, you can indicate whether "Sprinkler protection above the false ceiling" will be included by activating the corresponding box and entering the "Air void height" value (in which case the "2 layers" column will be marked in the list).
  You can also use the wizard in the upper toolbar to perform a joint import of all the spaces read in the IFC file based on the desired property, thereby generating one table entry for each group of spaces with the same property (which can then be adjusted by clicking the "Edit" option).
  On the right, the program allows you to view the layout of the selected spaces in the model.
  Any spaces that you do not intend to calculate must be removed from this classification table.

The program will assign the selected space type to all the rooms read from the IFC file that have the value indicated in the property shown in the wizard, and it will generate the geometry of the zones, adding them to the model view.

Elements entered

The data of each of the elements entered in the model can be consulted and edited, such as their reference, their 3D layout, their type and their characteristics, in the following tables:

• Spaces

Design parameters

• Calculation equation
  Selects the equation for calculating the pressure drop:
  • Hazen-Williams
    The Hazen-Williams calculation method is one of the most widely used due to its simplicity of calculation, but it cannot be used with any liquid other than water. This is the default method selected.
  • Darcy-Weisbach
    The Darcy-Weisbach calculation method is more accurate than the previous one, but more complex, due to the calculation of the friction factor. This method is required in certain specific cases by some standards, such as NFPA 13. The choice of this calculation method allows the following parameters to be set:
    • Specific gravity
      Ratio of fluid density to water density at 4°C.
    • Relative viscosity
      Ratio of the kinematic viscosity of the fluid to that of water at 20°C.
    • Precision
      Convergence criterion used to indicate that the solution to the non-linear equation has not been found. The iterative calculation ends when the sum of all flow differences divided by the sum of all line flows is less than the number indicated in this section.

• Pressure drop in pipes
  Inserts a safety coefficient which increases the pipe lengths to simulate pressure losses due to singular elements such as elbows, crosses, tees, valves, etc.
  • Increase coefficient
    This value must be greater than the unit. For example, to represent a head loss increase of 15%, a value of 1.15 is entered.

• Pressure drop due to fittings (optional)
  By activating this option, fittings such as connections, elbows, tees or crosses are generated during the calculation according to the geometry of the network and can be displayed in the 3D representation of the system. Furthermore, in this section, the program can configure the head loss coefficient associated with the different types of fittings generated, both in the branch with direct flow and in the branch with change of direction, if applicable.
  • Connection (Direct flow)

  • Elbow at 90º (Change of direction)
  • Standard Tee (Direct flow, Change of direction)
  • Cross connection (Direct flow, Change of direction)

• Seismic analysis (optional)
  By activating this option and setting the following parameter, users can enter and analyse seismic bracings in the installation using the options in the "Bracings" group of the main toolbar.
  • Seismic coefficient 'Cp'
    This can be entered directly or using the wizard on the right to obtain it from the "Spectral response acceleration parameter at short periods (Ss)", according to "SEI/ASCE 7, Minimum Design Loads of Buildings and other Structures".

Pipe options

• Checks
  Activates and configures the following checks on the pipes:
  • Maximum velocity (optional)
    Maximum velocity of the fluids permitted in pipes.
  • Maximum allowable pressure drop (optional)
    Maximum allowable pressure drop ratio for any given pipe span, expressed as a percentage. If the pressure difference between the initial and final nodes is greater than the indicated value, a warning shall be displayed on the pipe warning that the span must be redesigned.
    This option is used to quickly detect spans that, due to their dimensions, produce large head losses and therefore need to be redesigned. The default value is 40%.

• Quantities
  • Generate the support quantities (optional)
    Activating this option automatically generates the measurement of the pipe supports from the geometry of the installation entered in the model. The option on the right configures this measurement by editing the "Maximum spacing between supports" for the different pipe materials and diameters.

The checks to be carried out on fire hose reels can be defined for each type of space in "General options" in the "Project" group of the top toolbar.

Emitters

Inserts a generic emitter.

The emitters allow the simulation, analysis and hydraulic design of any element of a fire extinguishing installation (sprinklers, fire hose reels, hydrants, etc.), without depending on the geometric and hydraulic restrictions of the sprinklers and fire hose reels that are entered through the other options in this group.

When entering or editing an emitter, the following parameters can be configured:

• Reference
  Emitter reference. Identifies the element entered in the report.
• K-Factor
  Discharge factor of the emitter for calculating the flow rate.

The program does not perform any checks on the emitters but, thanks to the EPANET calculation engine, it is able to perform the hydraulic analysis of the designed system. Furthermore, on the program interface, the flow and pressure data obtained for each of the emitters entered can be displayed.

Wet riser

Enters a wet riser outlet.

This element acts in the same way as a sprinkler, fire hose reel or emitter, being connected at any point in the system and assigned to the desired design scenarios in order to obtain the flow rate and pressure resulting from the analysis.

When entering or editing an outlet for a wet riser, the following parameters can be configured:

• Reference
  Reference for the wet riser outlet.
• Catalogue / Selection
  The program can be used to select a wet riser outlet from the manufacturer's catalogues included in the Open BIM Database. These can be downloaded from the "Catalogue management" option in the "Project" group.

As with the emitters, the program does not carry out any regulatory checks on the wet riser outlets, but, thanks to the EPANET analysis engine, it is able to carry out the hydraulic analysis of the designed system. Moreover, on the program's interface, it is possible to visualise the flow and pressure data obtained for each of the wet riser outlets entered.

Assign

Used to assign or unassign elements in the fire extinguishing system (sprinklers, fire hose reels and emitters) to any of the defined design scenarios, to indicate that they are open, active or in operation.

If an element is not assigned to a scenario, the program will consider that it is not in operation and will not perform a hydraulic check on it.

Visible

Used to display a design scenario for the work area.

The program marks the position of the elements that are assigned to the viewed scenario with spheres.

To distinguish it, the operating area of the sprinklers active in the selected scenario, formed by the sum of the areas protected by each sprinkler, is also marked with a colour.

The program also incorporates the following checks during the analysis to ensure the correct distribution of seismic bracing in the installation:

• Detection of the start and end points of manifolds and uprights for the insertion of the corresponding bracings near them.
• Analysis of the distribution of the bracings along the pipes.
• Detection of the sections of the installation without seismic bracing and, therefore, not protected against earthquakes.

These verifications are shown as incidences on the installation in case they are not fulfilled. In order to solve them, the number or layout of seismic bracings in the installation must be modified.

The program also incorporates the following checks during the analysis to ensure the correct distribution of seismic bracing in the system:

• Pipe size
  Checks that the pipe size of the sway brace is equal to or greater than the diameter of the pipe it holds.
• Distance between hangers
  Checks that the distance between hangers does not exceed the maximum value.
• Maximum brace load
  Checks that the load assigned to the brace does not exceed the maximum value allowed by the selected component types.
• Maximum fastener load
  Checks that the load assigned to the fastening does not exceed the maximum value allowed by the selected component types.

Also, by clicking on the "Consult checks" option, a complete data sheet with the data, the detail plan and the analysis results of the selected bracing can be obtained.

Assign

Assigns or unassigns pipes of the fire extinguishing system to certain seismic bracing.

When clicking on a seismic brace, a dialogue box appears where users choose whether they wish to "Assign" or "Unassign" pipes to it. After accepting, the program lights up the pipes that are already assigned to it or those that are not yet assigned, depending on the selected operation. This way, the desired pipes can be selected to complete the operation.

Update results

This will analyse the entered system according to the latest changes, including all design scenarios, update the calculated parameters in the elements and check if they are within the permitted ranges.

The result is a direct display with error or warning messages about the parts of the system that have a problem or fail a check, as well as the results and reports available after the analysis in the "Checks" section of the editing panel of the elements that have this feature.

Design

Designs the network according to the indicated loadcase, automatically selecting the size of the pipes.

The "Design" panel has two options:

• Select the analysis scenario for which you want to design the system
  Select one of the defined analysis scenario in order to carry out the design. The number of sprinklers, fire hose reels, emitters and wet riser outlets assigned to the scenario is shown in brackets.
• Type of design
  • Total
    The entire job is designed.
  • Partial
    Only the design of the part of the system downstream of a given control point is carried out. To do this, after accepting the panel, a "Control point" previously entered in the installation must be selected.

In the editing panel of some elements such as tanks, the program can also be used to design the element with the corresponding tool in the lower right-hand area.

Show/Hide results

If this option is activated, the elements in which an error has occurred are highlighted. By hovering the cursor over these elements, the message describing the error can be displayed.

Checking results on screen

After carrying out the analysis, the program displays the results in the tooltip or information text that appears when the cursor is hovered over an element in the system. To do this, the "Show information texts" option in the top right-hand toolbar must be checked.

Checks in the editing panel

The program also displays the "Checks" of the last analysis performed in the corresponding section of the editing panel for each element, as well as its compliance status.

Graphical analysis of the results

Using the "Graphical analysis of the results" option in the "Calculation" group of the main toolbar, the calculated values of different quantities are displayed with the spans of the water distribution system marked with colours.

By default, the program displays the minimum and maximum values of each factor obtained in the calculation for the entire system. However, the colour scale can be adjusted according to the specific ranges of minimum and maximum values defined in the corresponding dialogue box.

The results available in the graphical analysis of results are as follows:

• Flow rate
• Velocity
• Pressure loss
• Length
• Head

Job reports

The program can also print the following reports directly with the printer or generate HTML, PDF, TXT, RTF or DOCX files:

The reports are obtained via the "Reports" option in the "File" menu or via the specific option at the top left of the interface.

• Project
  Displays a project report that includes the following sections:
  • Index
  • Hydraulic analysis
    This includes the general data of the project and the flow/pressure graph of the system.
  • Nodes
    • Node reference.
    • Elevation of the node.
    • Type of node.
    • Flow in the node.
    • Pressure in the node.
  • Pipes
    • Reference of the initial and final nodes.
    • Initial and final elevation.
    • Diameter.
    • Length.
    • Flow and velocity of the flow.
    • Initial and final pressure.
    • Loss coefficient.
    • Friction factor.
  • Seismic bracing
    Justification sheets of the seismic bracings provided.

• Material schedule
  Displays the material schedule with the measurement of the elements arranged in the system.

Drawings in DWG, DXF or PDF format

This allows users to print the job drawings of the single-line diagram on any graphic peripheral that is configured on the computer, or to create DWG, DXF or PDF files.

The following options can be configured when editing the drawing:

• Views to be drawn
• Options
  • Generate vector images
  • Draw the DXF/DWG template
  • Include .glTF files in drawings
• Resolution
• Scale
• Details

The drawings can be obtained through the specific option at the top left of the interface or through the "Drawings" option in the "File" menu.

Update

Update information contained in models previously imported into the project or import new models if desired.

In the update process, just like the process of creating a new job, the spaces in the BIM model can be read and assigned to one of the types of spaces defined in the project options. This way, the program generates the spaces automatically or updates them according to the latest changes.

Share

Exports the system information developed with the program to BIMserver.center to share it with other users.

During the export process, information related to the identification of the files to be exported can be defined:

• Name
• Description
