modelSpeedControlled_y

Information

This model describes a fan or pump with prescribed normalized speed. The input connector provides the normalized rotational speed (between 0 and 1). The head is computed based on the performance curve that take as an argument the actual volume flow rate divided by the maximum flow rate and the relative speed of the fan. The efficiency of the device is computed based on the efficiency curves that take as an argument the actual volume flow rate divided by the maximum possible volume flow rate, or based on the motor performance curves.

See the User's Guide for more information.

Revisions

• March 24, 2017, by Michael Wetter:
  Renamed filteredSpeed to use_inputFilter.
  This is for #665.
• December 2, 2016, by Michael Wetter:
  Removed min attribute as otherwise numerical noise can cause the assertion on the limit to fail.
  This is for #606.
• March 2, 2016, by Filip Jorissen:
  Refactored model such that it directly extends PartialFlowMachine. This is for #417.
• February 17, 2016, by Michael Wetter:
  Updated parameter names for #396.
