WebNov 18, 2024 · The Guts of an Economizer. The economizer set up employs several parts in order to operate correctly. 1) A set of outdoor air dampers that are directly linked to the return air dampers are used to control air flow. They move together as one, as the outdoor air dampers begin to open, the return air dampers begin to close and vice versa. Webregion 1, the economizer operates in the minimum OA mode. Regions 2a and 2b are the only OA conditions where the control action between DBT vs. enthalpy control is different. When in region 2a, bounded by the room DBT, enthalpy, and the saturation curve, the OA is placed in the minimum air mode when using enthalpy control since the
