Outdoor air sensors
There is one sensor mounted on each Adiabatic unit that monitors the temperature and humidity of the outdoor air. Each sensor reports the data to the AHU controller.
Adiabatic units
Each IT section of the HP POD 240e NA has six Adiabatic units that maintain the differential pressure and temperature parameters within the HP POD 240e NA.
For more information about the required power for the Adiabatic units, see "Power distribution: Adiabatic system (on page 28)."
Controlling the hot aisle fans
There are 10 exhaust fans located in the hot aisle of the HP POD 240e NA.
