Installation 26
Cooling system
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
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 27).
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).
water is not covered by the warranty.
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:
1. Unlock the latch for that fan overhead.
Cooling system 27
2.
Pull the overhead down.
Condensation management
CAUTION: During operation, avoid leaving the HP POD doors open, to minimize
Supply cooling water that is above the dewpoint inside the HP POD to reduce condensation forming on
the heat exchangers, and also cold enough to maintain the cold aisle temperature setpoint. If both
conditions cannot be met during the HP POD startup, adjust either the cooling water or the cold aisle
temperature setpoint above the dewpoint by one degree every fifteen minutes. During this process, the
coils act as a dehumidifier and establish conditions inside the HP POD for sustained operation. Significant
amounts of condensation might drain from the HP POD during the startup process, if the conditions inside
the HP POD are very warm with high humidity.
During normal operation, some condensation might form on the heat exchangers, and it will be collected
in the heat exchanger drip tray. The drip trays then collect and drain through the condensate drains out of
the HP POD.
HP recommends connecting condensate drains on the HP POD to a facility drain to prevent the collection
of water near the HP POD.
There are three 1.9 cm (¾ inch) condensate drain outlets across the rear of the HP POD directly
connected to the heat exchanger drip trays. The water main external drain is located at the front, left
corner of the HP POD. A fifth drain is located on the (optional) humidifier. For specific drain locations, see
Drain locations ("HP POD drains" on page 28).
condensation conditions.
To avoid excessive buildup of condensate and to conserve energy, consider raising the cooling water
temperature above the dewpoint to manage condensation while maintaining the necessary cooling
capacity.
HP POD drains
Cooling system 28
WARNING: Any water that drains around the HP POD causes a potential slip hazard. Use
caution where slip hazards are present.
Water from natural condensation might form. Condensation from the heat exchangers flow to the three
condensate drains across the rear of the HP POD (1). The water main drain catches any water from a
water main leak (2). The humidifier drain removes excess moisture from the air (3).
Item Component
1 Heat exchanger condensate drains
2 Water main supply/return drain
3 Humidifier drain
IMPORTANT: You might have to pipe directly to your local storm or sanitary drain, depending
on local jurisdiction.
If your HP POD is located indoors, you can connect to an external drain line. If your HP POD is located
outdoors, the drained water will simply drip from the HP POD drains out the back of the HP POD.
HP recommends connecting the condensate drains on the HP POD to a facility drain to prevent collection
of water near the HP POD.
Leak detection
If too much water accumulates in a drain tray, an alarm is triggered and sent through the BMS, indicating
that there might be a leak. For more information about alarms, see BMS alarms (on page 41).
Cooling system 29
Water quality requirements
Water quality requirements and specifications
• Closed-loop water must not contain any lime scale deposits or loose debris.
• The water must have a low level of hardness, particularly a low level of carbon hardness.
Additionally, the water must not be so soft that it attacks the materials with which it comes into
contact.
• The chilled water temperature to be supplied to the HP POD is 12º to 24ºC (55º to 75ºF). Freezing
water might cause a blockage and damage to the unit. In outside locations subject to freezing
temperatures, an additive such as glycol might be necessary to lower the freezing point. However,
the heat transfer potential of the water is lower, so the equipment must be derated properly.
Acceptable water quality specifications
Water must be maintained per the following acceptable water quality standards.
If your water is out of range, consult a water quality expert.
Water quality requirements 30
Frost damage
To avoid frost damage, the water temperature must not be allowed to fall below the minimum permissible
temperature of +4 ºC (+39.2 ºF) at any point in the water cycle.
The water cycle must be drained completely using compressed air before storage or transportation at
freezing temperatures or below.
Plumbing materials to avoid
Do not use the following materials in a closed water system:
• Oxidizing biocides
• Aluminum components
• Brass components with high levels of zinc
• Non-stainless steel Iron components
Water precautions
Take the following precautions before installation of the HP POD:
• Verify that all foreign matter and particulates are flushed from the system.
• Evaluate the short-term and long-term system requirements against the available water capacity.
• Ensure that the chilled water loop is properly designed for liquid cooling systems and is separate
from the sanitary water systems in your building (bathroom, sink, drinking water).
• Ensure facility managers understand the additional load being added to the chilled water supply of
the building. Be aware that the added heat load might affect other components being cooled by the
chilled water plant.
Water temperature
Without a water distribution kit, the temperature of the water supplied to the HP POD must be 12º to 24ºC
(55º to 75ºF). Freezing water might cause a blockage and damage to the unit.
Water quality requirements 31

reaching the condensate drains.
If additional humidity is required, connect your facility water to
the humidifier supply on the front of the HP POD.
The humidity of the HP POD is maintained between 30–70% to
ensure that dangerous levels of static electricity cannot build.
Frequently asked questions 47
Question Answer
Is the HP POD weather resistant? If there is an external leak, the HP POD is weatherproof and
has sufficient protection against the encroachment of water
inside the HP POD.
What happens if there is an internal leak? If there is an internal leak, the water collects in the condensation
drain pans or the water main drain pan. The additional water
present in the condensation drain pan triggers a Leak Detection
alarm, sent over the BMS.
What will happen if water stops flowing to
the HP POD?
The building BMS receives a High Temperature alarm. An EPO
will occur automatically if the hot aisle temperature exceeds
66°C (150ºF).
HP recommends shutting down all IT components or pressing
any EPO button to manually power down the servers, to
maintain server health, until the root problem can be solved.
At what smoke level will an alarm be
issued?
You can set the four different ranges at which the ASSD panel
smoke detector issues an alarm. For more information, see the
smoke detector manual supplied with the HP POD.
Can I switch out my servers and other rackmounted components?
The HP POD supports any IT equipment that uses front to rear
air flow cooling to maintain thermal integrity.
If you must remove a server or other rack-mounted component
for any prolonged period, you must replace it with a similar
component or a heavy-duty blanking panel so that the HP POD
interior can maintain thermal integrity.
How will I be notified if there is an
emergency in the HP POD?
The smoke alarm automatically detects incipient fires and
activates several different types of fire alarms:
• Visible—Internal and external HP POD strobes
• Audible—Horn
• Remote notification through the building fire alarm control
panel (optional)
Water emergencies are detected through the fire alarm control
panel and drain trays, an alarm is initiated, and the building
BMS is notified.
If the fans are not functioning correctly, an alarm is initiated
and the building BMS is notified.
