Abstract
An air control system 20 and associated methods including a flexible duct 30 having air exit holes 40, 42 and a flexible liner 50, 60 sheet within the duct 30 and extending longitudinally along the duct, the liner 50 sheet having opposite longitudinal edges 52, 54 connected to the duct 30 along the longitudinal length of the duct 30, the liner 50 sheet being permeable in one aspect and regulating air flow through the exit holes 40, 42 when the sheet is pressed against the portion of the duct having the exit holes, and an air exit hole positioned in the duct downstream a terminal end of the liner sheet such that air exits the duct through the air exit hole to reduce or eliminate retrograde airflow along a length of the duct.
Claims18
An air flow control system comprising:
- an elongated duct having a first set of air exit holes positioned along a bottom portion of the duct and a second set of air exit holes positioned along a top portion of the duct;
- a liner sheet positioned within and extending longitudinally along the duct, the liner sheet in part defining a first longitudinal compartment and a second longitudinal compartment within the duct such that air directed longitudinally along the first longitudinal compartment escapes through the first set of air exit holes and air directed longitudinally along the second longitudinal compartment escapes through the second set of air exit holes;
- and
- at least one air exit hole positioned in the duct downstream of a terminal end of the liner sheet such that air exits the duct through the at least one air exit hole.
