Abstract
Example air duct systems for supplying conditioned air to comfort zones include various example inflatable tubes with various example dampers. The dampers move noticeably slowly and/or its opening is delayed to reduce the rate at which the tube is inflated by a supply air blower. Depending on the particular example, the damper can be either at the inlet end of the tube or at the tube's opposite end. In some examples, the damper is controlled by an actuator that is powered by air or driven by an electric motor.
