As shown in FIG. 2, the first air conveyance device 2 is provided at a position obliquely above the position of the second air conveyance device 3. The first air conveyance device 2 may be provided at a position immediately above the second air conveyance device 3. Further, the first air conveyance device 2 may be provided at a position on the side of the second air conveyance device 3. The 1st air conveying apparatus 2 has the 1st air blower 20 which ventilates air. In the first embodiment, the first partition opening 21 is a blow-out port for blowing out the partition air 7, and the first opening 22 is a suction port for sucking air in the external space 5. The 2nd air conveying apparatus 3 has the 2nd air blower 30 which ventilates air. In the first embodiment, the second partition opening 31 is a blow-out port for blowing out the partition air 7, and the second opening 32 is a suction port for sucking air in the external space 5. Any one of the first partition opening and the second partition opening may be an outlet.

  Here, the inside of the boundary line 6 (broken line in FIG. 2) connecting the first partition opening 21 and the second partition opening 31 is the living room space 4. In the living room space 4, for example, there are people 8, for example, a table 9 is placed. Further, the outside of the boundary line 6 is the external space 5. The boundary line 6 is a line connecting a center point 23 in the height direction (arrow Z direction) of the first partition opening 21 and a center point 33 in the height direction (arrow Z direction) of the second partition opening 31. is there.

In the first air transfer device 2 and the second air transfer device 3, the direction of the partition air 7 flowing through the first partition opening 21 and the direction of the partition air 7 flowing through the second partition opening 31 are determined by the external space 5.
