<p><P>PROBLEM TO BE SOLVED: To converge a room pressure to a set pressure at an early stage after closing a door. <P>SOLUTION: The opening of an adjusting damper (41) is adjusted so that each room pressure is its set pressure in an A-room and a B-room communicating with each other through a door. When the door is closed, the opening of the adjusting damper (41) is adjusted by PID control of a "normal mode", whereas the opening of the adjusting damper (41) is adjusted by PID control of a "door open mode" in which a control gain is set lower than that of the "normal mode" while the door is open. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
