.Buildings.Templates.Components.Actuators.Damper

Information

This is a container model that can be used to represent a variety of dampers. The supported damper types are described in the enumeration Buildings.Templates.Components.Types.Damper.

Control points

The following input and output points are available.

For modulating dampers:

• The damper opening is modulated with a fractional opening signal y (real).
  y = 0 corresponds to fully closed. y = 1 corresponds to fully open.
• The actual damper position y_actual (real) is returned.
  y_actual = 0 corresponds to fully closed. y_actual = 1 corresponds to fully open.

For pressure-independent dampers:

• The airflow setpoint is modulated with a fractional airflow signal y (real).
  y = 0 corresponds to zero airflow. y = 1 corresponds to the maximum airflow.
• The actual damper position y_actual (real) is returned.
  y_actual = 0 corresponds to fully closed. y_actual = 1 corresponds to fully open.

For two-position dampers:

• The damper is commanded open with a Boolean signal y1.
  y1 = 0 corresponds to fully closed. y1 = 1 corresponds to fully open.
• The open end switch status y1_actual and closed end switch status y0_actual (Booleans) are returned.
  y1_actual = false corresponds to fully closed. y1_actual = true corresponds to fully open. And the opposite for y0_actual.

Model parameters

The design operating point is specified with an instance of Buildings.Templates.Components.Data.Damper.
