As shown in FIG. 2, the first air transfer device 2 is provided at a position obliquely above the position of the second air transfer device 3. The first air transfer device 2 may be provided at a position directly above the second air transfer device 3. Further, the first air transfer device 2 may be provided at a position on the side of the second air transfer device 3. The first air transport device 2 has a first blower 20 that blows air. Further, in the first embodiment, the first partition opening 21 is an outlet for blowing out the partition air 7, and the first opening 22 is a suction port for sucking the air in the external space 5. The second air transport device 3 has a second blower 30 that blows air.
