Multiple Configurations

A single compressor junction can contain information for multiple compressor configurations - impeller trims and operating speeds. This is useful to compare different variations of a compressor without needing to redefine a new compressor junction for every case. The configuration of the compressor can easily be changed without losing any information.

Defining Multiple Configurations

When opening the compressor configuration, change the Configuration Method from Simple to Multiple. When doing so, an additional user input panel appears on the right hand side of the window.

In order to make use of the multiple configuration feature, an RPM and Impeller Diameter under Configuration Information should be filled in. A Description can optionally be added. After modifying any information that affects the definition of this configuration the Update Configuration box turns yellow:

Clicking Update Configuration Now adds the Configuration to the Compressor Configurations listed in the top-right.

To create an additional configuration, click Create.

Figure 4: Creating a new Configuration

The compressor curves must be created and curve fit, as with a single configuration compressor. After completing this and clicking Update Configuration Now, the new configuration will be created and shown in the Compressor Configurations area. Configurations can be edited by selecting them in this area

Now that multiple configurations are available, they can be selected on the Compressor Model tab:
