It was necessary to bring even the 101 suction port.

In order to route these ducts,
In the horizontal direction on each floor, the space above the ceiling is used, and in the vertical direction connecting the floors, a space is provided in an unobstructed part of the wall, and a duct is passed through the space.

However, in such a conventional method, since the duct arrangement space is not positively and intentionally incorporated into the house, the duct arrangement for cooling and heating and the duct arrangement for ventilation are systematic. Therefore, the duct routing distance becomes longer than necessary, and as a result, the pressure loss of the air flow increases and the air conditioning performance deteriorates. There was a problem that the number increased. In addition, as described above, since the duct installation work is performed using the space above the ceiling or the space inside the wall, there is a problem that the installation work is also difficult and time-consuming.
