METHOD OF LAMINAR FLOW CONTROL USING A DOOR ASSEMBLY

摘要

A method of operating a door assembly may include pivoting a first door about a first pivot axis from a closed position to an open position such that the first door acts as an inlet. The method may further include pivoting the first door to the closed position, and pivoting a second door about a second pivot axis from a closed position to an open position when the first door is in the closed position such that the second door acts as an outlet facing in a direction opposite the first door. The method may additionally include pivoting the second pivot axis about the first pivot axis when pivoting the second door, the second door being of a smaller size than the first door and forming at least a portion of the first door.
