Accepted Answer

Option C: The more the exhaust and outside air dampers are open, the more the recirculation damper is closed, and vice versa.. Damper linkage coordination ensures that as outside and exhaust dampers open to introduce fresh air, the recirculation damper proportionally closes to balance mass flow.
