するように制御を行うものである。To explain the operation in the above configuration, indoor air RA
As shown by the arrow, the air is exhausted from the indoor air duct 2 by the exhaust blower 13, through the duct 2b by the branch pipe 3, through the heat exchanger 10, and then exhausted to the outdoors by the outdoor exhaust duct 8. When the indoor blower 11 is operated, the outdoor air OA passes from the outdoor air supply duct 6 to the heat exchanger 10 as shown by the arrow, exchanging heat with the indoor air RA, and then flows into the main body 1 through the duct 2a. After mixing with the indoor air RA that has entered, the air is heated or cooled by the heat exchange coil 12 and supplied to the room 14 through the indoor air supply duct 4. The exhaust blower 16 directs the air inside the toilet 15 to the outdoor exhaust duct 8a.
From the connecting portions 21b and 21C, the air is exhausted to the outside through the exhaust duct 8d and the outdoor exhaust duct 8 for ventilation. Similarly, the exhaust blower 18 directs the air in the bathroom 17 to the outdoor exhaust duct 8d.
Connecting portion 21c, exhaust duct 8d, outdoor exhaust duct 8
Ventilate the room by exhausting it outside. The exhaust blower 20 connects the air in the washroom 19 to the outdoor exhaust duct h8c through the connection part 21.
b, 21c to the outside through the exhaust duct 8d and the outdoor exhaust duct 8 for ventilation. At this time, the backflow prevention shutter 22a of the exhaust duct 8d on the upstream side of the connecting portion 21a and the backflow prevention shutter 22b of the exhaust passage 9 of the main body 1 are closed, and the odor-laden exhaust from the toilet 15 is
prevent the influx of Conversely, the exhaust blower for each small room 16.
When the operation is stopped at 18.20, the backflow prevention shutters 22a of these exhaust ducts 8d are closed, and the backflow of exhaust from the main body 1 is also prevented. In addition, when the heat exchange ventilation air conditioning unit 1 and the exhaust air blower 13 are operating, the air supply balance is disrupted by the amount of exhaust air from the exhaust blower 13, and the pressure difference between the indoor pressure and the outdoor pressure is reduced. The differential pressure sensors 23a and 23b detect that the indoor pressure is negative compared to the outdoor pressure, and based on the input signals from the differential pressure sensors 23a and 23b, the control means 24 controls the indoor pressure to be a constant pressure compared to the outdoor pressure. Control is performed to increase the air volume of the indoor blower 11 of the heat exchange ventilation air conditioning unit 1 so that the difference becomes larger.
