Since the total amount of air discharged by 200c (displacement is constant) is larger than the amount of outside air introduced, the building 10
The inside of 0 becomes negative pressure. It is not preferable to leave this state as it is because the door becomes difficult to open.

The detected value of 220 indicates negative pressure. Therefore, when the detection value of the pressure sensor 220 indicates a negative pressure, or when it becomes less than a predetermined value, the pressure information is sent to the controller 220, and the controller 220 drives the outside air introduction fan 300 according to this pressure information. You can do it.

It is possible to introduce the necessary amount of outside air that has been subjected to the damp treatment into the rooms 1a to 1d, which leads to energy saving. Furthermore, the negative pressure in the building 100 can be eliminated.
