Proper maintenance is crucial. Introduction of pretreated OA from a DOAS unit to the mechanical room plenum is similar to introducing it to the unit inlet, but allows for air mixing in the mechanical room prior to being drawn into the air handler that serves the occupied spaces. Buildings are ventilated through a com­bina­tion of uncontrolled ventilation (draughts, air bricks and trickle vents, etc) and, increasingly in new homes, controlled ventilation solutions such as mechanical ventilation with heat recovery. Close to Mech room Mechanical room & outdoor air opening locations Mechanical rooms Below Grade Mechanical rooms partialy or.
