HP POD cooling system

CAUTION:

Contaminated supply water might cause decreased cooling capacity or disruption

in service. The supply water must meet the guidelines states in the HP Performance-Optimized

Datacenter Site Requirements Information document. Damage caused by contaminated supply

water is not covered by the warranty.

The HP POD has 12 heat exchangers that maintain temperature and cool the equipment installed in the

HP POD. The HP POD heat exchangers receive chilled water from either the water distribution kit or your

facility, cycles the water through the heat exchangers to cool the air, and then the fan units circulate the
cool air throughout the HP POD.
To control the fan speed, you must set a cold aisle temperature through the BMS. A predetermined

differential pressure setpoint between the hot aisle temperature and cold aisle temperature is factory set,

and cannot be altered. The fan units regulate speeds to maintain the cold aisle temperature and

differential pressure between the hot and cold aisle. For more information, see Controlling the fan speed
(on page

Water supply temperature

If you are using a water distribution kit, water is supplied to the HP POD between 13°C and 24°C (55°F
and 75°F). HP recommends that you supply water to the water distribution kit between 4°c and 10°C

(40°F and 50°F).
If you are not using a water distribution kit, HP recommends supplying water to the HP POD between

13°C and 24°C (55°F and 75°F).

Controlling the fan speed

The HP POD fans operate at variable speeds to maintain a predetermined differential pressure setpoint

between the hot aisle and the cold aisle. You set your desired cold aisle temperature through your BMS,

and the fan speed adjusts to maintain the differential pressure setpoint between the hot and cold aisle
temperatures.
You cannot manually adjust the fan speed.
To access the fan units:

Unlock the latch for that fan overhead.
