PURPOSE: Discharging amount control system and method are provided to maintain constant discharging amount by the installation of a first sensor sensing the pressure of the air supplied from an air supply unit and a second sensor sensing the pressure of the discharged air. CONSTITUTION: A discharging amount control system comprises an air supply unit(10), a multi-duct unit(20), and discharging units(40). The multi-duct unit is connected to the air supply unit and a plurality of spaces(50a,50b,50n). The discharging units are respectively installed in the space and discharge the air provided through the multi-duct unit. Each discharging unit comprises a first sensor, a second sensor, and a discharging amount controller. The first sensor senses the pressure of the air provided from the multi-duct unit. The second sensor senses the pressure of the air discharged through the discharging unit. The discharging amount controller controls the pressure difference of the air detected by the second sensor and the first sensor to be the same to a reference pressure and discharges the same amount to the spaces.
