Description of the Related Art In a hospital room for an infectious disease patient, in order to prevent infectious pathogens generated from the patient from flowing out of the room, the room pressure is controlled to be negative pressure rather than the room pressure. Negative pressure control is disclosed in JP-A-10-272138 and JP-A-7-4.
As disclosed in Japanese Patent Laid-Open No. 61-61, it is performed by adjusting the supply amount and the exhaust amount of conditioned air supplied to the room, and the air for the differential pressure is transferred from the outdoor to the indoor through the differential pressure adjusting damper. Supplied.

ことが必要になる。However, when the differential pressure between the room and the outdoor is adjusted by using the differential pressure adjusting damper as described above, unclean air containing bacteria, fungi, and dust floating in the atmosphere is removed from the outdoor by the differential pressure adjusting damper. Since it is supplied to the room through the interior, there is a drawback that the cleanliness of the room is reduced. In addition, since the unclean air containing dust and the like that has flowed into the room in this way leads to the supply of nutrients to pathogenic bacteria, it is necessary to ensure the cleanliness of the room even in an infectious disease room where negative pressure is controlled. . Therefore, when the differential pressure is adjusted by using the differential pressure adjusting damper as described above, it is necessary to mount the HEPA filter also on the differential pressure adjusting damper.
