<P>PROBLEM TO BE SOLVED: To provide a room pressure control device capable of suppressing fluctuation of room pressures of a plurality of rooms connected with one air conditioner by simple control. <P>SOLUTION: This room pressure control device 10 for controlling the room pressures of the rooms connected with the air conditioner through air supply passages to a target value, includes an air conditioner control portion 14 for determining an air volume controlled variable of the air conditioner by constantly determining the controlled variable from a deviation value to a target value on the basis of quadratic function characteristics from a first deviation value between a measured value of static pressure of the air supply passage measured by a first pressure meter 51 disposed in the air supply passage and a target value of the static pressure of the air supply passage, and an exhaust damper control portion 16 for determining an opening controlled variable of an exhaust damper 41 for exhausting the air in the room, on the basis of quadratic function characteristics from a second deviation value between a measured value of a room pressure of the room measured by a second pressure meter 52 disposed in the room and a target value of the room pressure of the room. <P>COPYRIGHT: (C)2012,JPO&INPIT |
