Abstract
Systems and methods for improving operation of a heating, ventilation, and air conditioning system, which includes a scrubber unit coupled to an air handling unit via a return air conduit. The scrubber unit includes a contaminant filter, which sorbs air contaminants from a surrounding environment when at a target pressure differential and releases previously sorbed air contaminants into the surrounding environment when at target temperature, a return inlet actuator coupled to a return inlet damper, and scrubber control circuitry programmed to determine parameters of outside air and instruct the return inlet actuator to ramp the return inlet damper from a closed position to an open position during a bleed phase of a regeneration cycle to enable venting of the previously sorbed air contaminants using return air when the parameters of the outside air are not within corresponding target parameter ranges.
