ROOM PRESSURE CONTROL SYSTEM AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide a room pressure control system and method for minimizing the pressure fluctuation of an object room caused by opening/closing of a door. SOLUTION: The room pressure control system 10 comprises: object rooms 12A-12C having doors 30W-30Z; dampers 18A-18C regulating the supply air capacity; differential pressure sensors 22A-22C measuring the pressure values of the object rooms 12A-12C; and a control device 36 controlling the dampers 18A-18C based on the differential pressure sensors 22A-22C and controlling the opening/closing of the doors 30W-30Z. The control device 36 maintains the doors 30W-30Z in the closed state until the pressure fluctuation measured by the differential pressure sensors 22A-22C is settled within a predetermined range.
