Abstract：
Aiming at overpressure ventilation in the sorting and emergency department of civil air defense medical engineering, points out the problems existing in overpressure ventilation mode. Proposes a combination mode of overpressure exhaust air and self-circulation ventilation and analyses its characteristics. Verifies the removal effect of the two modes by the solution of differential equation. Presents the design suggestions for the mode combining overpressure exhaust air and self-circulation ventilation.
