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).

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.
Parameter Range
pH 8.0–10 Specific conductance at 25ºC
(77ºF) Alkalinity ("M" as CaCO3) 150–1000 ppm Sulfur (SO4) 0–150 ppm Chloride (Cl) 0–100 ppm Hardness (CaCO3) 0–350 ppm Calcium hardness (CaCO3) 0–200 ppm Magnesium hardness (CaCO3) 0–150 ppm Copper (Cu) < 0.20 ppm Iron (Fe) < 3.0 ppm Aluminum (Al) < 0.50 ppm Sodium (Na) 0–1000 ppm Silica (SiO2) 0–150 ppm Zinc (Zn) < 1.0 ppm Manganese (Mn) < 0.1 ppm Phosphate Ortho- (PO4) < 3 ppm Bacteria < 1000 CFU/ml Suspended solids < 10 ppm
0–2500 µmhos/cm
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.

Maintenance

Periodic maintenance

Perform periodic inspections of the POD to ensure there is no sign of overheating. During periodic

Electrical busway maintenance

inspections, pay special attention to electrical connections and wiring.
Periodically tighten the electrical busway connections. HP recommends tightening the electrical busway connections every six months.
Inspect the busway drop boxes for loose connections, and tighten if necessary.

Water system maintenance

HP does not maintain your water system quality. Consult a water treatment specialist to perform the following maintenance: Flush the HP POD How often you must flush the HP POD depends on how often you shutdown the HP POD and the water
quality. Maintain water quality The water treatment specialist should periodically take a water sample and add new chemical treatments
to the HP POD water or water distribution kit as needed to maintain the specified water quality ("Water
quality requirements" on page 30).

Air filter replacement

There are twelve 14 in x 36 in x 1 in air filters inside the HP POD. If you have the optional air filter sensor (on page 44) installed, you will be notified through your BMS
when you need to change a filter. If you do not have the sensor installed, HP recommends periodically inspecting and changing each air
filter.

Air and water heat exchanger maintenance

The air and water heat exchanger requires no maintenance. If particulates are present in the cooling water, a filter must be fitted immediately upstream from the water inlet fittings. Check the functionality of the condensation drainage system regularly. Regularly perform visual inspections for leaks (annually).
