Heat Exchanger Design Module

From this point there are two possibilities:

  1. Create each part of the heat exchanger manually
  2. Use the creation module for heat exchangers

We will use the second option to efficiently create all parts of a standard heat exchanger. Later parts can still be added or deleted. The second option also gives the possibility to create a setting plan, with the first option this is not possible.

Use the arrow next to the seventh button to get the drop down menu and select 'heat exchanger' to create a new equipment (heat exchanger) in the project database. Alternatively, select from the menu Item > New > Heat Exchanger.

The following dialog window will be shown:

Figure 5: Heat exchanger type selection

Enter the equipment number at 'Heat exchanger number'. An example equipment number used here is 'HE-101'.

Enter the revision or issue number of the calculation. Usually the revision starts '0' or 'A'. The revision number will also be shown on the calculation sheets. The revision is an important identifier of the various issues or updates of the calculations. Enter the date of the revision in the next field to indicate the revision date.

Enter the description or name of the equipment at the 'Heat exchanger description' field. An example of the name is 'Boiler'. The name usually references the process function of the equipment in the unit of the plant.

Enter the username or company name in the 'User name' field. The name will be shown in the title block of the calculation sheets and indicates the originator of the calculation.

Choose a type of head for the closure at the ends. This setting of the type of head will be ignored in case of flat covers at the ends.

Select the type of the supports by clicking one of the radio buttons. The type of saddles is depending the orientation (horizontal or vertical) of the equipment. The type exchanger (horizontal or vertical) and supports can not be changed later since it is a vital part of the data structure in the database

The tube side pass configuration is to be selected for one pass exchangers only. This will set the inlet and outlet nozzle at either side (front/back) of the exchanger. The VES application will than take the configuration into account by creating a larger end channel with the outlet nozzle. In the calculation this nozzle and channel will be added to the calculations.

Select the Tema type clicking the relevant pictures or use the dropdown menus below the pictures. The graphic will show the a general representation of the selected types.

Note: The selection of the Tema type and the support type can not be changed afterwards. If this dialog is closed these settings are fixed because they are fundamental to the creation of the equipment and the selection of the details of the equipment. In case the type of the exchanger is changed the equipment has to be deleted and a new type has to be created.

Figure 6 - Main window, complete with equipment components

At the top of the window the main information of the equipment is shown. The fields except for the ItemID can be edited if required. The save button will save the changes made. The VES application has now created the equipment based on the selections made in the previous dialog.

The main window shows in the 'Equipment part list', the relevant parts as indicated above figure. At the 'Equipment part list' the applicable calculation code can be selected, Rules for pressure vessels (The Netherlands), ASME (USA), AD Merkblätter (Germany) and EN (Europe).

The relevant calculations are shown if a part is double clicked or the plus (+) mark next to the part is clicked. The calculations are still empty because the details of the equipment need to be completed first.
