4.2.3 Underfloor ventilation
In the underfloor ventilation setup, air blown out of the air conditioner is fed into the

the surrounding space.
This setup is useful in the following cases:
 Larger server systems including high heat dissipation volume unit(s)
 Intricate layout including tall equipment
