HVAC Design Features

AVEVA Marine has been designed by HVAC Engineers for HVAC Engineers. The HVAC application offers the following key benefits. The HVAC Designer application lets the user build up and detail complex ducting networks simply by selecting components from standard catalogues. By using standard default settings, a conceptual layout can be created and analysed rapidly, leaving the design details to a later post-approval stage. The application provides facilities for creating rectangular, circular and oval cross-sectional items. Individual design components can be selected from over 100 parametric catalogue items covering all likely requirements, including a range of auxiliary items such as stiffening frames, access panels, splitter plates etc., all of which will be accurately detailed in the design model. The catalogue also includes a range of inline plant items such as centrifugal and axial fans, air handling units, silencers, dampers etc. each ready for insertion into the design model in a single operation. User-definable detailing specifications, such as those for construction materials, ductwork gauge, flange dimensions etc., define precise manufacturing requirements. User-definable default settings ensure compliance with company standards and a high level of design consistency throughout the project. Accurate geometric representation of all design items ensure reliable clash checking during the design process, leading to good space management and the early elimination of positional errors, which can be expensive to rectify at the construction stage. This is particularly important where different features of the design model are under the control of different designers.

Explicitly positioned design components are interconnected automatically with implied ductwork as the design of the ductwork sequence is built up. An auto filling facility is provided which can then calculate the optimum use of standard ducting straights to complete the material take-off for the entire network. Several design aids are incorporated, including a facility for creating horizontal grids which can be used to position ceiling tiles. This can greatly aid the layout of building services in an architectural environment. Also for systems, in a marine environment, a facility exists for splitting the system design into logical sections to assist design and manufacture. HVAC elements may be named in accordance with a predefined set of rules, so that their positions in the database hierarchy are always obvious without the user having to enter specific texts during the design process. The applications user interface can be tailored readily to suit the level of experience of any individual user. In particular, graphical illustrations of all catalogue items can be displayed if required to simplify component selection and dimensioning. At any stage, the user can create reports listing specified data from the current database. A standard report template can be specified, allowing the user to derive lists of commonly required information very quickly; alternatively the user can design a one-off report format to suit specific needs. The resultant output, which can include data from any design discipline, sorted in any way required, can be either displayed on screen or sent to a file for storage and / or printing.

2.1

Starting an Outfitting Session To start the AVEVA Marine application, select All Programs > AVEVA Marine> Design > Marine 12.1 > Outfitting The AVEVA Marine - Outfitting Login form appears, enter the following data: Project Username Password MDB

Training HVAC HVAC HVACFWD,

Check the Integrate Engineering and Schematics check box. Then click the Login button.

Setting the project to Training on the AVEVA Marine Outfitting Login form will result in the use of the Marine Training Project; this will be referred to as MTP for the remainder of this guide. A default screen layout will be displayed comprising the application pull-down menu and a Design Explorer showing all the objects from the current project database. The user can reposition and, in some cases, resize the Outfitting windows.

Once the Outfitting module has been started, the user must check that the HVAC application is running. This can be seen on the top of the design framework. If it does not show HVAC, select Design > HVAC Designer from the application pull-down menu to change to the correct application.

2.1.1

Learning about AVEVA Marine Database Hierarchy

Although this guide is about the design of HVAC ducting networks, in practice ductwork is usually routed with reference to predefined design items such as a framework, Decks and Bulkheads etc.

2.2

How AVEVA Marine Stores Design Data

All Outfitting data is stored in the form of a hierarchy. An Outfitting Design database has: a top level, World (this can be represented by the symbolic name /*) a two principal administrative sublevels, Site and Zone. The names used to identify database levels below Zone depend on the specific engineering discipline for which the data is used. For HVAC design data the lower administrative levels (and their Outfitting abbreviations) are: HVAC (HVAC) BRANCH (BRAN) SPOOLS (HSLIST)

AVEVA Marine (12.1) HVAC Modelling TM-2223 Each HVAC element can represent any portion of the overall ducting network. Each Branch within an HVAC element represents a single sequence of components running between two, and only two, points: Branch Head Branch Tail The data which defines the physical design of the individual HVAC components is held below Branch level. The overall format is as follows:

Creation and Routing of HVAC Components

3.1

HVAC Components Representation in the Catalogue

Each HVAC component is represented in the AVEVA Marine catalogue by the following types of data: Physical shape Parameters

3.1.1

HVAC Physical Shape

The physical shape of a component is defined by a set of geometric primitives, so that a component can be manipulated and linked to adjacent HVAC items. All principle points needed to define the component position orientation and connectivity are identified by uniquely numbered tags. These tags, which have both position and direction, are called P-points: Each P-point is identified by a number of the format P0, P1, P2 etc. P0 always represents the components origin position. The principle inlet and outlet points are also identified as P-Arrive (PA) and P-Leave (PL). P1 is the same as P-Arrive, and P2 is the same as P-Leave.

3.1.2

HVAC Variables

The setting of all variables needed to distinguish a component from others with the same geometry and Ppoint sets are defined by parameters. The values of these are defined to suit the specific design requirements. For example, a rectangular three way component (or branch connector) might be represented in the AVEVA Marine catalogue as follows:

P2 (P-Leave or PL)

P0 (Origin)

P3 (Branch Connection) P1 (P-Arrive or PA)

The two curved duct sections from the component geometry set The four P-points from its point set P-point, P3, enables the user to control the direction of the branch connection arm when it is incorporated into the design The dimensions of the component and other constructional details are represented in the catalogue by parameters whose values are set to suit the design requirements.

AVEVA Marine (12.1) HVAC Modelling TM-2223

3.2

Setting HVAC Defaults

The following defaults will need to be set for the users to complete the exercises. A default detailing specification The format of the HVAC form Customised HVAC forms

3.2.1

Setting a Default Detailing Specification

The constructional detail of components that the user selects from the HVAC catalogue, such as joint types and maximum straight lengths, are determined by the current default specification, which is shown on the HVAC Designer toolbar. The TUTORIAL specification is set as default, however for the examples and exercises in this guide the HVAC will be created using the MACHINERY_SPACE_VENTILATION specification. This gives access to a range of catalogue components that are suitable for use with this module. Note that when starting a new session, the specification will need to be set each time.

3.2.2

Choosing the HVAC Form Format

All the principle functions for creating, positioning, orientating and connecting HVAC elements are available from within a single form, the HVAC form. The HVAC form has two display formats: The brief form, the default, uses drop-down lists to show the elements available for selection. The full form uses scrollable lists to show the elements available for selection, and also offers more complex positioning options To display the HVAC form select Create > HVAC

To display the full form right click the mouse over the form and select Use Full Form

This provides access to a more detailed form with additional options to that shown on the standard form. © Copyright 1974 to current year. AVEVA Solutions Limited and its subsidiaries.

AVEVA Marine (12.1) HVAC Modelling TM-2223

3.2.3

Customising HVAC Forms

The appearance and behaviour of the forms for creating and modifying HVAC components can be customised. This enables modification of the forms to suit individual preferences or for the type of design work being undertaken. Right click the mouse on the form and select Style Options

This displays the HVAC Form Style form. Set the check boxes as shown. The result of checking these boxes is as follows: Show Local Views Local Views Shade OK / Cancel Forms

Show Pixmaps Show Forms

Displays a small 3D graphical view showing the current component in its design context. Shows local views in colour shaded as opposed to a wire frame representation Uses OK and Cancel buttons instead of Apply and Dismiss on the forms. This will result in the corresponding forms closing when OK or Cancel is selected as opposed to remaining available for repeated use until dismissed explicitly. Displays a sketch showing components geometries to help the user select items from the catalogue. Displays the Create / Modify form automatically when a new component is added to the design. This allows the user to adjust the default dimensions and / or orientation as required.

AVEVA Marine (12.1) HVAC Modelling TM-2223

3.2.4

Creating a Backdrop for Design

Before starting to model HVAC elements some Equipment and Hull panels need to be added to the 3D view so that they can be referenced. Add the following elements to the 3D view: Hull Block F102 Hull Block F106 Equipment elements MCS2001 and MCS2002 (located in ZONE A01-EQUIP)

MCS2002 MCS2001

The two items of equipment are the machinery space air intake fire dampers, and the HVAC ducting created in the following examples and exercises will originate from the HVAC nozzles owned by these items of Equipment.

AVEVA Marine (12.1) HVAC Modelling TM-2223

3.3

Creating HVAC Administrative Elements

The next step is to create the administrative elements which govern the position of individual HVAC components within the database hierarchy. The first elements are: An HVAC system element An HVAC branch element (the branch head) Ensure the hvac specification is set to MACHINERY_SPACE_VENTILATION.

3.3.1

Creating an HVAC System Element From the Design Explorer, select ZONE 210-HVAC to make it the current element.

From the Categories section of the HVAC form select HVAC Branches and from the Available Types section, select HVAC System Element

On the Create HVAC form, in the HVAC Name text box, key the name TRAIN_210_MCS_001 and press the Return key on the keyboard. The Primary System pull-down menu lists the systems available in the System Group World (SYGPWL) for HVAC. Set the Primary System to Machinery Space Ventilation Supply. Click the Apply button to create the element or Dismiss to remove the Create HVAC form

The Primary System displayed in the pull-down menu is actually the Description of the System Group (SYSGRP). The user must ensure the Description for the SYSGRP is set for the pull-down menu to be meaningful.

17

AVEVA Marine (12.1) HVAC Modelling TM-2223

Note For the Primary System pulldown menu to be populated with the options available in the HVAC System Group Area (SYGPAR) the function of the SYGPAR must be set to HVAC.

The Primary System set for the HVAC element on creation can be changed or removed using Utilities .See section 6.5 of this guide.

3.3.2

Creating an HVAC Branch Element

There are two types of HVAC branch element Main branch Side branch These differ only in the way they are added to the design: A main branch requires the user to position and orientate its head explicitly. A side branch takes its head position and orientation from a branch connection point P3 on an existing three way component.

The first HVAC branch element will be a main branch element, the branch head. From the HVAC form, select Main Branch Element from the Available Types section.

The HVAC Main Branch Element form is displayed, in the form set the following: Branch Name TRAIN_210_MCS_001/B1 Make sure that the Branch Head Shape is set to Circ (Circular duct). Set the Head Direction to -Z (this is the direction looking along the axis of the duct from the head position towards the first component). Set the Duct width AA to 1000. Set the insulation thickness to 50mm (this adds 50mm of insulation automatically to each surface of all components and ducting owned by the branch). Set the Head Start to ID Nozzle (The 3D position can also be picked using ID Design PPoint; this would enable the user to indicate the position of the Branch Head by selecting the Ppoint on the nozzle.) Click the Apply button. © Copyright 1974 to current year. AVEVA Solutions Limited and its subsidiaries.

AVEVA Marine (12.1) HVAC Modelling TM-2223

3.4

Creating HVAC Components

The next stage is to build the HVAC design starting from the branch head. The individual components are added sequentially, positioning and orientating each component in turn. The first component to be added to the current arrangement is a rectangular to circular transformation. This is to be positioned at the nozzle of equipment MCS2001.

3.4.1

Creating the First HVAC Component

From the HVAC form, select Transformations from the Categories list. The HVAC Shape Transformation Items form appears, Select Square to Round and the Square to Round Transformation form appears. This form has data fields for all parameters needed to define the component. The initial data setting on the component definition forms are determined by a set of default values. Fill in the form as below.

The Picture button on the Square to Round Transformation form allows the user to interpret the parameters easier. This displays the HVAC component form containing a dimensioned and annotated drawing showing how the component is defined in the catalogue. In this case, it can be seen that the default Arrive and Leave settings for this transformation are the Arrive is the square end, and the Leave is the circular end. The Flip Circ/Rect option on the form allows this to be reversed. For this example the Arrive needs to be circular, therefore the Flip Circ/Rect is set to Yes.

Click the Dismiss button. From the Design Explorer it can be seen that there are two new elements: BEND2 - This represents the Square Bend SPLR1 - This represents the set of air deflectors within the bend. This is created because a square bend requires turning vanes. The message that appeared during the creation of the component was created was a warning to the user that this component is comprised of more than one AVEVA Marine element. Navigating to the square bend simply by picking it with the cursor, will almost certainly select the element representing the outer ducting. The air deflectors that also form part of the component are below the bend in the hierarchy. Consequently in order to create the subsequent component the user must select the element that represents the air deflectors.

The user can see the deflectors inside the bend by changing the view to wireframe mode with the use of the F8 key to toggle

Extending the HVAC Model

In the previous section the user created a sequence of components to form the main branch and side branches of the HVAC ductwork. The following section the user will: Learn how to position tiles using a working grid. Extend the model with the use of side branches as shown previously. This part of the training will involve the modelling of design data using the Machinery Control Room in the ship machinery space. This will require the use of circular duct components as opposed to the rectangular sections mainly used so far. Circular components are easier to use than rectangular components because the user is not required to consider the duct width and depth, instead only a single parameter of duct diameter needs to be allowed for. The 3D view needs to be set up as follows, to enable the worked example to be completed: Add Hull Block F107 to the 3D view. The 3D view needs to be clipped so the bulkheads defining the boundary of the Machinery Control Room are clearly visible. Set two clipping planes as show below, using Clipping and Options > Planes. First the clipping planes defined previously need to be cleared. In the Clipping Planes form, select Tools > Clear all clip planes.

Set the view direction to ISO3.

The HVAC Branch created in the previous exercise (BRAN TRAIN_210_MCS_002/ B2) will be extended, by way of a circular Branch connection, to route ducting to ceiling diffusers located in the ceiling tiles which will be created in the next section.

3.7.1

The Grid / Tiling Utility

The subsequent sections will involve the routing of duct work to connect to diffusers positioned in ceiling of the Machinery Control Room. However before modelling can begin the user must set out a working grid and position the ceiling tiles within it, so that they can be used as a reference to position the HVAC grills later. With reference to the existing design model, the next stage of the HVAC ducting network to be designed will feed two diffusers above the small compartment in the starboard side of the compartment. To aid the positioning of these diffusers, the user will set out a horizontal grid which in turn determines the ceiling tile layout based on a specified datum point. There are three stages to tiling: Specify a setting out point (SOP) to represent the datum from which grid line positions are to be calculated. Create grid lines at specified intervals, referenced from the SOP in a horizontal plane. Add tiles at specified positions in the plane of the grid. Navigate to Site HVAC_2DK_FWD and create a new Zone named one 203HVAC. The grid / tiles are created below this level in the hierarchy.

Select Utilities > HVAC Tiles / Grid Layout > Setting Out Point from the main menu pull-down.

This displays the HVAC Grid Setting Out Point form. Key in the S.O.P. Name MCR_SOP1 and enter the Setting Out Point Height of 13200, (this is the elevation taken from above), then click OK

The user is then prompted t Use 2D Cursor to Position . This initial position is only an approximate position. It will be moved to the exact centre of the room later. Using a Plan view (Plan Y) pick a point near the centre of the compartment as shown.

The Design Explorer will now contain a STRU and a DISH as shown. The setting out point is shown graphically in the position picked. The position of the SOP can only be picked when the 3D view direction is orthogonal.

54

AVEVA Marine (12.1) HVAC Modelling TM-2223

To move the point to the centre of the compartment ensure the DISH element is the current element and select Position > Using Ship References from the main menu pull-down. Enter the coordinates X 149900 Y-1800 Z 13000 on the Explicit Position form. Click Apply and then close the form. The next stage is to define a grid in the Z-plane (a horizontal reference grid) through the SOP datum, with the gridlines spaced out from the SOP in both directions.

Select Utilities > HVAC Tiles / Grid Layout > Grid from SOP from the main menu pull-down.

This displays the HVAC Grid form, leave the default settings of 600 and 600 and click OK. If the SOP DISH element is not the current element the user is prompted to Identify the Grid SOP .

The horizontal rectangular area which represents the grid boundaries must now be defined. The user is prompted to Position the lower left grid e . With the graphical view set at Plan Y, indicate the lower left point of the area in the graphical view. This is followed by the prompt Position the upper right grid e . Indicate the upper right position to complete the area definition. Upper Right

The corresponding grid will now be added to the graphical view and the Design Explorer will be populated with numerous DRAW elements.

CHAPTER 4

4

Completing the Design

In this chapter some facilities for enhancing the basic HVAC design model are examined. The main features described are: Replacement of implied ducting by catalogue straights. Addition of stiffening flanges to ductwork items. Item numbering of HVAC components. This will be demonstrated using the duct work that was created in the previous worked examples, HVAC TRAIN_210_MCS_001.

4.1.1

Filling Ductwork Gaps

During the creation of the main branch, components were specified with specific functions, such as bends, side connection points, silencers and dampers. Most of the gaps between these components were left undefined and were filled by implied ducting to complete the representation shown in the 3D view. To enable the design to be prefabricated, it is necessary to specify the fixed lengths of ductwork (ductwork straights) required between these components. This will also enable a full material take-off to be generated. The HVAC application is able to calculate the optimum combination of standard and non-standard straights needed to fill each gap and then create the corresponding components in the design database automatically. Clear the 3D view, and disable the clipping planes. Navigate to the main branch TRAIN_210_MCS_001/B1 and add it to the 3D view. To confirm the presence of gaps in the branch, select Utilities > Auto fill with Straights > Show Gaps

The Highlight Implied Ductwork (HVAC) form appears, click Apply For each gap in the named branch, the scrollable list area of the form shows the: Location (the preceding component) Length Calculated combination of straights to fill the gap

All corresponding lengths of implied ducting are highlighted simultaneously in the graphical view. The CE button on the form allows multiple branches to be checked.

AVEVA Marine (12.1) HVAC Modelling TM-2223

to allow for this. Click Dismiss to close the Highlight form. Select Utilities > Autofill With Straights > Fill Gaps

Click Apply on the form. A list of identified gaps is displayed and the specified straight lengths are created automatically to replace the implied ducting. The design explorer shows the new elements.

To ensure the Autofill operation was completed satisfactorily the user can repeat the Show Gaps process. The message No Gaps To Show

4.1.2

Adding Stiffening Flanges

AVEVA Marines provides a utility for calculating the optimum number and positions of stiffening flanges needed to support ductwork items. The configuration of the flanges is tailored to suit the component geometry in each case. The user can then create and position such flanges automatically. In the branch membership hierarchy, they are treated as sub-components of the straight. Navigate to the straight shown below (STRT2) and make it the current element, select Rectangular and Stiffener from the main HVAC form.

www.aveva.com © Copyright 1974 to current year. AVEVA Solutions Limited and its subsidiaries.

72

AVEVA Marine (12.1) HVAC Modelling TM-2223

The stiffening requirements are calculated, and displayed in the Rectangular stiffening form. AVEVA Marine has calculated that this component has a spec requirement of 3 stiffening flanges.

To create the 3 stiffening flanges, click the Apply the Spec Requirement button, the flanges are created and positioned automatically.

The number of stiffening flanges required may vary, dependent upon how the HVAC was routed previously.

To complete this procedure for the remaining elements of the branch the user can navigate to the element and clicking the Q Spec Req button to update the form. The Apply Spec Requirement button can then be clicked, the user will then be prompted with a confirm message.

Click the Yes button to confirm and add the stiffeners. This process can be repeated along the branch adding stiffeners to each rectangular component shape; square bends, mitred bends, radiused bends etc. The flanges are configured to suit each different component shape. (Note that square to round transition pieces will not allow rectangular stiffening to be added.)

Different shading identifies individual components; heaviest lines show flanges joining components together

4.1.3

Automatic Item Numbering and Naming

The item numbering facility automatically allocates sequential item numbers to all HVAC components and gives each item a name of the format: < number>

where /PREFIX is a user definable string and number is the sequential number.

Sub-components, air deflectors, stiffening flanges, etc. are numbered as decimalised subsets of their owning components. Inline equipment items, silencers, fire dampers, etc. which are usually named, remain unchanged. To auto number all HVAC items in the current design model, navigate to the owning HVAC element, BRAN TRAIN_210_MCS_001/B1. Care should be taken if the selected owning element is the system element as opposed to the branch element because the branch order below may not be in sequence. This is important if the itemisation is to be consistent with the branch numbering, i.e., B1, B2, B3 etc.

Select Utilities > Automatic Itemising, the HVAC Itemising form appears, key in the Naming Prefix HTEST/ITEM, leave the start number set to 1, and click Apply

The HVAC command Output window is displayed, listing all HVAC items and their allocated numbers. Comparing the entries in this itemising list with those in the Design Explorer, it can be seen that each item (with the exception of any inline equipment components) has been named in the design explorer using the specified prefix /HTEST/ITEM suffixed by the item number. i.e., the straights in the main branch, and their stiffening flange subcomponents, appear as follows:

4.1.4

Finishing off Design Details

The final design details can now be completed for the ductwork. This will involve: Modifying joint types to suit the final design Inserting an access panel into the side of a duct.

4.1.5

Modifying Joint Types

When the length of implied ducting leading to the control damper (VCD1) was replaced with straight components, the connecting joints will have been assumed to remain as default flanged joints. In fact, the control damper requires raw edge joints (the VCD joints were changed earlier in this guide), so that the ducting simply fits over the damper inlet and outlet.

The inlet joint for the damper is the leave joint for the straight that precedes it. To modify this joint navigate to the preceding straight element.

On the HVAC form, click the Modify CE button, the Rectangular Straight form is displayed. Click the Choose button.

AVEVA Marine (12.1) HVAC Modelling TM-2223

4.2.3

Seal Plates

A Seal plate is a part that seals the HVAC as it passes through a panel, bulkhead, deck etc. There are various types, sometimes they are simply plates just larger than the hole/penetration, and are welded/attached to the panel and HVAC duct. Other types might be specifically designed HVAC penetration elements that are part of the bulkhead/deck panel and then the HVAC system is routed up to it.

AVEVA Marine provides the user with the capability to create a simple plate type seal plate. To do this the user must have already created the HVAC penetration as previously detailed. Navigate to the fixing in the Design Explorer an make it the current element. Select the Utilities > HVAC Penetration > Seal Plates, this will open the Seal Plates form and create a new STRU in the ZONE VH_Coaming_Zone.

The Seal Plates form allows the user to key-in the Plate Overlap, Plate Thickness and to specify the Panel Side. The Plate Overlap allows for the dimensions of the original hole that has already been created. In the example shown the original hole was modified to be 900x750, consequently the corresponding seal plate with a Plate Overlap of 50mm will be 950x800 as shown. The Panel Side is in relation to the direction of the ducting.

Once the values have been entered click the Update button. This will make the Remove button active which allows the seal plate to be removed. Click Remove then Close the form.

4.2.4

Non-Penetration Managed Holes

Free Holes

Sometimes access may be required through Hull or Structural panels in order to allow access to HVAC equipment. To facilitate this process the Hole Management application allows the creation and management of Non- Penetration Managed Holes, or Free Holes. As these access holes have no penetrating item, the holes may be created by a Structural or Hull designers. However, in reality the structural designer may not be aware of the requirement for an access hole, therefore this option is also available to other Outfitting disciplines, including HVAC Modelling. The requested hole will then be controlled by the Hole Management application, with a Structural Designer responsible for approving the requested hole. Free Holes are standard hole shapes, some of which include sleeves or kicker plates. A User Defined shape is also available. This option is also available in other Outfitting modules.

4.2.4.1 Free Holes In the HVAC application, selecting Utilities > HVAC Penetration > Create Hole from the main menu displays the Create Hole form.

Clicking the Pick Item for Hole button prompts the user to

.

Unlike penetration holes, only one penetrated item may be selected. The Hole Type list shows the available holes. The first six entries are the same hole types available for penetration holes. The remaining hole types are various shapes with additional components, i.e. kicker plates or sleeves. The last entry is User Defined which enables a user defined shape for the hole to be specified, see section 4.2.4.2.1. After selecting a hole type from the list, clicking the OK button on the form displays the Hole Management Free Hole Definition form. The selected hole shape is displayed graphically, using default sizes, on the penetrated item with aid graphics that indicate the Hole X and Hole Y directions and the default X and Y offsets from the panel origin. The default hole location is the pick position from the penetration item selection. This default position may be subsequently changed on the Hole Management Free Hole Definition form. The Hole Management

Free Hole Definition form has three tabs:

Hole Definition to define the shape, size, position and rotation of the hole. Coaming (The Coaming tab is to be removed in a future product release so is therefore not described in this training guide) Associated elements to define the element(s) the hole is to be associated with, e.g. piece(s) of equipment.

82

AVEVA Marine (12.1) HVAC Modelling TM-2223

4.2.4.2 Free Hole Definition - Hole Definition Tab On the Hole Definition tab, the used can change the following details and parameters, to suit the required hole. In the Hole type area, the Hole Type may be changed from that specified on the Create Penetration form by simply selecting a different type from the list. The graphical representation of the hole type will change to the new type. The Hole shape parameters area of the form changes depending on the hole type selected, with the relevant parameters shown for that hole type. For example, for a Rectangular Hole Type HR with Kicker Plate has parameters for the hole Width and Height, hole corner radius, and Kicker Plate Height and Thickness. The Hole Position and Orientation area of the form enables the X Offset and Y Offset, i.e. X and Y distances from the panel origin, to be set. The values default to the picked position and reflect the displayed values on the graphical aids. The X Offset and Y Offset values may be changed manually by entering the required value in the appropriate textbox. Alternatively, clicking the Align in X or Align in Y buttons prompts the user to and activates the Positioning Control toolbar. The user may pick any position, using any of the positioning control options to align the hole with in the specified direction. The X Offset or Y Offset values are changed automatically to reflect the picked position.

Clicking the Explicit Position icon prompts the user to . A new hole position may be picked on the panel using the cursor, as with the initial panel selection. The X Offset and Y Offset values are updated accordingly. The Rotation gadget enables the rotation around the Z axis of the panel to be specified either by entering a value in the textbox or using the up or down arrows to change the angle in 5° increments.

AVEVA Marine (12.1) HVAC Modelling TM-2223

4.2.4.2.1 User Defined Hole Type There is an option in the Hole type area of the form for User Defined free hole definition. This allows the user to create hole shapes other than the standard options available in the Hole type area of the form.

Selecting the User Defined hole type displays the Loop Vertex Editor form, i.e. the same form used for modifying panels and negative extrusions.

A default hole, an NXTR with four vertices, is displayed graphically. The Loop Vertex Editor form is displayed with vertex 1 current and a text aid is displayed at the vertex. The hole shape may be defined by adding, deleting or modifying vertices to the NXTR loop in the same way as editing a panel or normal negative extrusion.

reports the following types of occurrence (and other similar errors) in the design: Branch head or tail reference not set Branch Head or tail reference type not valid Adjoining components have incorrectly ordered PA and PL points, i.e., one component may have been flipped while its neighbour was not Distance between a component and a connected neighbour, or between a component and the branch head or tail, is not valid Neighbouring connected components, or a component and the branch head or tail, have their PA/PL misaligned Arrive or leave joint has wrong connection type To check the design for data consistency errors, select Utilities > Data Consistency, the Data Consistency Check form appears. This can either send the error report to the screen or a file. The Check list allows the user to specify how much of the design model to check in a single operation. To check each branch separately, select Branch from the list Navigate to the BRAN TRAIN_210_MCS_001/B1 and click the Apply button. The resulting diagnosis is displayed in the scrollable text area of the Data Consistency Check form.

The message that appears indicates that the branch connection from the Threeway component has not been explicitly terminated and is not connected to any external item. (Each branch would normally be connected to an equipment item or to some other ductwork in an adjacent design zone or compartment.

It is good practice to run a data consistency check whenever the user has created or modified a significant amount of HVAC, typically before using Save Work

Data Check Functions Further checking can be carried out using the Data Checker facilities, select Utilities > Data Checker

The Checker form is then displayed. The form contains four pull-down menus: Control allows the user to Save an existing check, Load a previously failed check. Reload Checks enables the user to add newly created checks to the form. This task would normally be done by an administrator. Add allows the user to include the elements to be checked using CE, CE Members, Pick, Failed List and List. This will in turn populate the Check Items section of the form. Remove uses All, Selected, CE, CE Members, Pick and List to remove items already placed in the Check Items section of the form. Highlight allows the user to determine how the representation of the results will be shown to the user.

The form includes a customised class of checks specific to the HVAC functions. AVEVA provide a small set of HVAC checks to introduce users to this powerful utility. The functionality of the Data Checker can be extended or modified using the AVEVA PML2 facilities.

comchecks.pmldat project defaults directory. The user can organise the checks by class and groups. An example file is shown; the class and group settings can be clearly seen. The example file produces form values as shown.

The Classes section of the form enables the user to indicate the type of design element that will be checked. This will filter the selections available under the Groups pull-down.

AVEVA Marine (12.1) HVAC Modelling TM-2223

The Groups section determines the level at which the check will be performed. As already stated the content of the pulldown is influenced by the Class that has already been set.

Setting the Groups section will in turn populate the Checks section of the form allowing the user to select the Check to be carried out. Once the Check has been selected from the list the Check button becomes active. Click the Check button to perform the check.

The results of the check will be displayed in the Checker Results form and highlighted graphically for cross referencing with the form. The Checker Results form is split into two sections: Passed will list all the elements that successfully passed the checker. Failed will list the elements that failed individually and describe the reason for the failure. The representation of the graphical view and the Checker Result form is controlled via the Highlight pulldown on the Checker form.

Generating a Tabulated Data Output

This section details a method of outputting design data derived from design model by generating a tabulated report showing the material required to build the design. The reporting utility reads selected information from the Dabacon database and presents the output in a tabulated format. Each report can be customised by specifying some or all of the following: Where the output is to appear (on screen or in a file ready for printing) An introductory header which is to appear at the beginning of the report The page length (if the report is to paginated) The page layout, including number and positions of columns, column headings, etc. Any headers and footers which are to appear at the top and bottom of each page The selection criteria which define which data settings are to be included in the report www.aveva.com © Copyright 1974 to current year. AVEVA Solutions Limited and its subsidiaries.

95

AVEVA Marine (12.1) HVAC Modelling TM-2223 Once such a report has been designed, its specification can be saved for further use in the form of a report template file. The results of the process will be seen by using a pre-prepared template which outputs a material take-off list showing the length of tube needed to build the design. A company standard report template will probably be used for most reports to maintain consistency Select Utilities > Standard Reporting > Reports > Run to initiate the reporting process. This displays the File Browser.

Navigate to the C:\AVEVA\marine\OH12.1\pdmsui\reports\templates directory by selecting it from the Subdirectories window. All files with a .tmp suffix are report templates.

Select the hvac_list.tmp file and click the Open button. This template has been designed to produce a list of the principle components (omitting sub-components and branch connectors) in the HVAC design. The Report Details form appears requiring the user to specify where the report is to be stored and what part of the database hierarchy is to be read when extracting the required types of data. Leave the Filename text box empty (this sends the report automatically to the screen) and in the Hierarchy text box, key-in /TRAIN_210_MCS_001/B1 (this lists the components for the whole HVAC branch), then click OK to run the report.

The tabulated report output is displayed in an AVEVA Marine Outfitting Command Output window which is opened automatically, (unless the Command Window is visible in which the report will be displayed there). The report lists all principle components in the specified network in branch head to branch tail order. The type and key dimensions for each component are tabulated as predefined by the template.

HVAC Splitting

6.1

Overview

HVAC systems are created as a series of branches and components throughout the route. Once the HVAC route is well defined and stable, the HVAC Splitting utility can be used to split the HVAC system. These splits may occur at logical breaks based on topographical features or at specific points along the HVAC route. The suggested workflow for HVAC is to define the whole route using the principle elements only (i.e. bends, dampers reducers etc). Leaving the spaces between these fittings as implied duct. The splitting can then be applied while the implied duct is still present: Split Line Implied Duct Split Line

Auto-filling gaps can be done after splitting

For the purposes of HVAC modelling there are two main forms to consider which are all available from the application pull-down menu:Move form Drag Move form

- accessed using - accessed using

10.1.1 Move Form The Move form is used to move the current element in a given direction. This can be a specified distance in that direction, to a position relative to another element, or relative to a plane through a given component. Both the forms have four common tabs:Distance Through Clearance Towards

10.1.1.1 Distance Tab

Movement Direction

The Distance tab allows the user to move the current element so that its origin or nominated PPoint moves a distance in a given direction.

Distance

The Parameters section of the Move form allows the user to set the following:Origin using a scrollable to select Origin, Arrive or Leave. Distance Direction WRT sets the frame of reference for the direction of movement With Respect To a specified element.

www.aveva.com 125

AVEVA Marine (12.1) HVAC Modelling TM-2223 The WRT setting can be influenced by the four buttons as explained:-

Direction with respect to itself

-

Direction with respect to owner or first ancestor that has an orientation

-

Direction with respect to the World

-

Direction with respect to a picked element

For very simple movements the Parameters section of the form can be employed on its own with the Target section using the Relative To setting of No Target, for example:-

Before

After

However the Target section of the form provides additional functionality:Relative To - allows the user to select from numerous options to determine how the element is positioned in relation to the target element or position. In Front / Behind

AVEVA Marine (12.1) HVAC Modelling TM-2223 With the Relative To option set to something other than No Target, the Select options become available to the user. The setting of this option determines how the remainder of this form will function as shown:Selecting the Element option allows the user to specify the element to be referenced either by keying in the name or by clicking the Pick Target Element button and indicating the element in the 3D View.

Alternatively, selecting the Position option forces the users to click the Pick Target Position button. This allows the user to use the Positioning Control toolbar to perform an EDG pick to specify the position in the 3D View.

The resulting position is indicated in the 3D View as an aid as shown.

The remaining options of Next, Tail, Previous, Head and Current require no additional input.

Checking the Plane Through Target check box allows the user to specify the direction of the Plane. The current element is moved so that its origin moves a given distance in a given direction, where the distance is measure from intersection of direction of movement and the reference plane. The reference plane is specified relative to the element or position nominated in the Select scrollable list.

The Parameters section of the form is identical to that detailed for the Move tab with the exception that there is no Distance input text box.

Unlike the Move tab the Target section must be used to perform an operation. The Target section of the form is similar to that detailed for the Move tab. However there is no Relative To scrollable list and the Through scrollable list is the same as the Select version on the Move tab.

Checking the Plane Through Tangent check box allows the user to specify the direction of the Plane. The current element is moved so that its origin moves to the intersection of the direction of movement and the reference plane. The reference plane is specified relative to the element or position nominated in the Through scrollable list.

10.1.1.3 Clearance Tab

Movement Direction

The Clearance tab allows the user to move the element in a given direction so that its obstruction volume or a Ppoint is a given clearance from another element. The clearance is measured in the same direction as the movement. Clearance

The Parameters section of the Clearance tab differs slightly in that the Origin also contains an All option which allows for any obstruction volumes. The user can also specify the amount of Clearance required. The remainder of this form works in the same fashion as the Move tab.

The illustration below shows how the Clearance tab can be used in conjunction with the Relative To options to great effect.

10.1.2 Drag Move Form

The Drag Move form is identical to the Move form except that it applies the Drag rules to a constrained network. In the previous examples the positioning commands do not move the connected elements. The construction of the constrained network depends on the direction of the drag operation and the type of item to be dragged. Refer to the Dragging Equipment and Piping Networks section of the Design Reference Manual for information relating to the boundaries of a constrained network.
