modelPartialOutdoorSection

Interface class for outdoor air section

Information

This class provides a standard interface for the outdoor air section of an air handler. Typical components in that section include

  • shut off OA dampers,
  • the OA side of the heat recovery unit,
  • the OA dampers of the air economizer.
