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)

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)

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.
