Dual-stage relief economizer

Carrier’s Dual Stage Relief Economizer (DSRE) uses a typical economizer with barometric relief and integrates an additional relief plenum from the building space up through the rooftop unit that bypasses traditional barometric relief dampers. The DSRE uses no motors, fans, or electricity to relieve building pressure at all varying conditions. This design has two relief operations: The first stage of natural relief is through the dedicated air chamber that provides relief when the building pressure warrants, regardless of the economizer damper positions or the indoor fan status. The second stage provides additional pressurization relief when the outside air damper is mostly open and space pressure warrants.
