Overview

This section provides a brief overview of the Reducer Rule tables.

The Reducer Rule table describes the rule to follow when connecting two routes of different sizes. If you want to connect the routes using a specific part, then the physical part subtype cell must be filled.

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

when using file-based tables, the Reducer Rule item in the resource table of HVAC Design Resources.
when using Engineering Specification objects, a specification in the resource table of HVAC Specification Resources.

Table Description

This section describes the customization options of the Reducer Rule.

File-Based Table

A typical Reducer Rule file-based table is shown below:


V_EquivalentDiameter	V_Shape	V_EquivalentDiameter2	V_Shape2	V_PhysicalPartSubtype

Engineering Specification Table

A typical Reducer Rule Engineering Specification table is shown below:


Equivalent Diameter	Shape	Equivalent Diameter 2	Shape 2	Physical Part Subtype

The columns definitions are as follow:


Column Name	Column Type	Link to Table	Link to Column
Equivalent Diameter	Nominal Size	Duct Reference Dimension	Equivalent Diameter
Shape	String	Duct Reference Dimension	Shape
Equivalent Diameter 2	Nominal Size	Equivalent Diameter	Equivalent Diameter
Shape 2	String	Equivalent Diameter	Shape
Physical Part Subtype	String	Part Subtype	Physical Part Subtype

The table has the following attribute:

Fluid
Fluid Category
Maximum Temperature
Minimum Temperature
Standard

Sample Resource File

This section explains where to find the sample resource file.

The default location of XXX_XXX_ReducerRuleDefinition.xls is

..\startup\EquipmentAndSystems\Tray\Specification\

and then the relevant specification, such as SS150R.
