Add Air Systems

Use the tools in the System Browser to add air systems.

The System Browser displays the hierarchy of the analytical systems and zone equipment.

To create an air system

  1. Open a model and press F9 to display the System Browser.
  2. Click Add Air System .
  3. In the Properties palette, under Identity Data, enter a name for the air system.
  4. Depending on the type of air system created, other properties are enabled. Under Energy Analysis, you can specify the Heat Exchanger, Preheat Coil, Cooling Coil, Heating Coil, and Fan.
    5. The tree in the System Browser displays the hierarchy of the analytical systems and zone equipment. The water loops and air systems are shown at the top level with their associated water loops and zone equipment shown below.

    If an element has not yet been fully defined, a warning icon displays in the System Browser.

    To designate an air system that is used only to provide ventilation air or a dedicated outdoor air system (DOAS) that will output to gbXML for systems analysis, create a project parameter with the following attributes.
    • Name = DOAS
    • Discipline = Common
    • Type of Parameter = Yes/No
    • Category = Air Systems

    In the model, enable the parameter for the dedicated outdoor air system. See Create Project Parameters for details.
