Auxiliary Equipment Properties Dialog: Aux. Equipment tab (Transfer Panel)

This tab is part of the Auxiliary Equipment Properties Dialog that is displayed for auxiliary equipment of the “Transfer Panel” type. This dialog can be accessed by clicking on the View/Edit button () from the Process Explorer Toolbar (Aux. Equipment tab) or on the Auxiliary Equipment Listing showing when selecting Tasks } Other Resources } Auxiliary Equipment... from the main menu of the application.

Variable Definitions, Ranges and Default Values

The following table shows the meaning of the variables appearing in this tab, as well as their default values and their generally acceptable range. Note that due to the manner by which the variables are used by the sizing and costing equations, the range of acceptable values may be further reduced.

Variable	Default Value	Range

○ Name The name of this auxiliary equipment resource.	TP-101	Any Text
● Type The auxiliary equipment type of this auxiliary equipment resource.	Transfer Panel	Any Text
○ Maximum Number of Parallel Engagements (Number of Bridges) Specifies how many active connections between inputs and outputs can be allowed simultaneously. Essentially determines how many operations can simultaneously be engaging this panel without triggering a sharing violation.	1	Positive
◙ Number of Units The number of parallel (simultaneously operating) units that this auxiliary equipment consists of.	1	Positive
● Size Variable Description The size variable of this auxiliary equipment type.	Volumetric Flow	Any Text
◙ Maximum Throughput The maximum volumetric throughput that a single unit of this type is available for purchase in the market.	1000.0 L/h	Positive
◙ Volumetric Flow The size (volumetric flow) of this specific transfer panel. The size is either calculated (if it’s set on ‘Design Mode’) by simulation engine based on the engagements of this unit or it is set by the user (if it’s set on ‘Rating Mode’).	0.0	Positive

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output

Specification Choices / Comments

The following list describes the available specification choices in this tab; for more details on how these are implemented, see Vacuum Pumps.

Sizing: Design Mode

In Calculate (Design Mode), the user specifies the Maximum Volumetric Flow and the program calculates the Number of Units and Volumetric Flow (based on the actual engagements by the operations that utilize this unit).

Sizing: Rating Mode

In User-Defined (Rating Mode), the user specifies the Number of Units and (rated) Volumetric Flow. The program simply displays a warning if the required volumetric flow per unit (based on utilization possibly synchronous by several operations) exceeds the specified (rated) Volumetric Flow of the panel.
