置。2. A plurality of air supply pipes for guiding air from one air supply fan to a plurality of rooms, a constant air volume device arranged in the air supply pipes in order from an upstream side, and a high airtightness on the air supply side. A damper, a plurality of exhaust pipes for guiding air from the plurality of rooms to one exhaust fan, and a high airtight damper for normal exhaust and normal exhaust pressure arranged in these exhaust pipes in order from the upstream side. An adjusting exhaust damper; a plurality of disinfecting exhaust branch pipes which branch off from the upstream side of the normal exhaust high airtight damper of the exhaust pipe and are connected to the disinfecting exhaust main pipe; A high airtight damper for disinfecting exhaust disposed, an exhaust damper for adjusting pressure during disinfecting exhaust, a disinfecting exhaust processing device and an exhaust fan for disinfecting exhaust disposed in order from the upstream side in the main line for disinfecting exhaust, and the constant air volume device. Set the air volume of the A controller for instructing opening and closing of the air-side high airtight damper, the normal exhaust high airtight damper, and the disinfecting exhaust high airtight damper; and automatically adjusting the opening degree of the pressure adjusting exhaust damper, thereby controlling the pressure in the room and the outdoor area. And a differential pressure regulator for maintaining a differential pressure with the pressure at a predetermined value, wherein the supply-side high airtight damper and the high airtight damper for disinfecting exhaust are opened, and the disinfecting exhaust pressure adjusting exhaust damper is opened. After the disinfecting exhaust by the disinfecting exhaust processing device and the disinfecting exhaust fan is completed, a normal exhaust control means used for returning the exhaust in the room to the normal exhaust using the exhaust pipe is provided. A small air volume setting means for setting the air volume setting of the constant air volume device to be smaller than a steady air volume by inputting a normal exhaust signal, and the air volume of the constant air volume device is controlled by the small air volume setting device. After the air volume reaches a fixed value, control switching means for switching the control by the differential pressure regulator from the disinfecting exhaust pressure adjusting exhaust damper to the normal exhaust pressure adjusting exhaust damper; and After the air volume set by the small air volume setting unit has been reached, the disinfecting exhaust high airtight damper fully closing unit that starts an operation of fully closing the disinfecting exhaust high airtight damper, and the disinfecting exhaust high airtight damper is fully closed. At the same time as the operation to start, the normal exhaust damper full opening means for starting the operation to fully open the normal exhaust high airtight damper, and the disinfecting exhaust high airtight damper is fully closed, and the normal exhaust Stopping means for stopping the exhaust fan for disinfecting exhaust after the highly airtight damper is fully opened; and increasing the air volume setting of the constant air volume device simultaneously with stopping the exhaust fan for disinfecting exhaust, and Air conditioning system, wherein the air flow rate changing means for the air volume, to become configured from.
