Cooling Solutions to meet the Cooling Solutions to meet the Higher Density RequirementsHigher Density RequirementsCooling Solutions to meet the Cooling Solutions to meet the Higher Density RequirementsHigher Density Requirements Requires moving the cooling closer to the heat source to;

– more precisely cool the specific load

– not waste energy - “brute force” by cooling the whole room.

Cooling coils may be in multiple locations;– External to the Rack – Overhead, Back, Side– In the Rack – Under, Side– Part of the Server

Requires a fluid to be delivered to the cooling coils to transport the heat out of the Data Centre. Can be;– Chilled Water (ChW)– Refrigerant (pumped low pressure)

XDV Nominal capacity >10 kW (2.8 Ton) @ 37°C EAT

–XD Coolant (R134A) changes from a liquid to a gas as heat is absorbed in the cooling coil and returned to the XDP to condense back to a liquid

Secondary Fluid ComparisonsSecondary Fluid ComparisonsSecondary Fluid ComparisonsSecondary Fluid ComparisonsPumped Refrigerant System

Advantages– No Water in the DC or

electrical hazards– Micro-channel coil efficiency

(+50%), lower air side pressure drop => lower operating costs

– Smaller piping requirements– Cooling Modules can be

located anywhere– Scalable Capacity (2-3x to CW )

Disadvantages– Small room scalability – Higher Fluid Cost

Chilled Water Based SystemAdvantages

– Lowest Fluid Cost– No limitation to room size

Disadvantages– Electrical Hazard– Operating Efficiency– May require fluid treatment to

prevent fouling– Limited overhead cooling

How Cooling closer to the source of the heat

makes the heat exchangers more efficient (higher entering air temperatures)

Lower total Fan HP

Sensible cooling eliminates wasted energy dehumidify unnecessarily and then having to re-humidify

Less Chiller or DX infrastructure required

Overhead cooling modules require no additional floor space

Cooling solutions that meet the cooling requirements to fill racks of high density servers

Results in … Less Power (energy

consumed)

Less Power (energy consumed)

SummarySummarySummarySummary Cooling solutions for higher density will need to move

closer to the load and will require a reliable fluid delivery means– Cost effective cooling solutions exist that can be

employed today that meet future needs– Allow racks to be fully populated

Cooling at the source of the heat load will actually lower your incremental energy consumption– Less power for the cooling system provides more

power for the IT equipment

Which leads to a significantly reduced TCO.
