It is the figure which modeled the example of application.

  In FIG. 1, B represents a building such as a hospital or a food processing factory that is relatively easy to ensure airtightness, and has at least one pair of an intake port V and an exhaust port E. A tank T filled with a sodium hypochlorite solution W (hereinafter referred to as a sterilizing and cleaning liquid W) is disposed on the upper part of the building B, and an infusion pipe communicating with the tank T by obtaining pressure from the pump P. The sterilization cleaning liquid W is supplied to each room through L.

  In the intake port V, an intake chamber CHi is connected to the indoor side of the building B. The intake chamber CHi includes an intake blower Fi for introducing outside air, a filter f for filtering outside air, a sterilizing and purifying portion CR for sterilizing and purifying outside air, and a mist separator m. The contaminated outside air can be supplied indoors as a clean one. The sterilization cleaning unit CR includes an injection unit J that sprays the sterilization cleaning liquid W, and gives effects such as sterilization and deodorization to the introduced outside air. The outside air that has been sterilized and purified is separated into excess moisture by the mist separator m, sent to the intake duct Di, and then filled into each room from the air supply port R of the intake duct Di.

  An exhaust blower Fo is provided on the indoor side of the exhaust port E, and the indoor air sent from the air collection port G through the exhaust duct Do is exhausted from the exhaust port E to the outside.

  At this time, the behavior of the intake blower Fi and / or the exhaust blower Fo is controlled by the control unit C that compares and calculates the atmospheric pressure measured indoors and outdoors by the atmospheric pressure sensors Pi and Po provided indoors and outdoors. And maintain the atmospheric pressure in the room so that it is always positive. First, when the intake air blower Fi is rapidly operated and the indoor air pressure becomes much higher than the outdoor air pressure, the operation of the intake air blower Fi is switched from normal operation to inertial operation in order to maintain this. When the indoor air pressure is close to or below the outdoor air pressure, the intake blower Fi is rotated more rapidly than usual to avoid this condition, and the indoor air pressure is always maintained at a higher level than the outdoor air pressure. To do. Accordingly, in any case, the outside air entering the building B can be surely sterilized and purified through the intake chamber CHi.
