Duct Specification

This section describes the Duct Specification table and how you can customize it.

This page discusses:

Overview

This section provides a brief overview of the Duct Specification table.

The Duct Specification table allows you to create filters between parts and a duct specification; it lists duct attributes for one specification. When searching for parts in the database, the system uses this table as an additional layer of filtration.

In Data Setup, this definition table should be assigned to:

  • The Duct Specification item in the resource table of HVAC Discipline Resources.
  • The value of Duct Specification in the Criteria column should be set to the name of the specification (for example Duct Specification = CS150R).

When users search catalogs and chapters for parts, there are three kinds of filters:

  • The Standard value is blank: all values appear.
  • The Standard value is set to a precise value: only parts which have this value appear.
  • The Standard value is set to Unset: only parts which have a Standard keyword value equal to NULL appear.

Table Description

This section describes the customization options of the Duct Specification table.

A typical Duct Specification table is shown below:

V_SubPartType(string)V_EquivalentDiameterV_ShapeV_WidthV_HeightV_CornerRadiusV_StandardV_Endstyle

To customize the table, enter a line in the spreadsheet for standard and shape attributes for every part subtype that you use.

If you want to define additional restrictions (criteria for parts queries), you can add as many columns you want to the file. Each column must be based on HVAC part attributes.

Sample Resource File

This section explains where to find the sample resource file.

The default location of XXX_XXX.xls is

..\startup\EquipmentAndSystems\HVAC\Specification\

and then the relevant specification, such as SS150R.
