Cooling System Optimiser

A dedicated data centre cooling controls platform, delivering resilience and redundancy for the lowest possible operational cost.

In every industry, the evolution of technology has fuelled the race to optimise use of natural resources. Data centres have risen to the challenge and embraced the importance of optimising their cooling equipment to create a more sustainable world for all.

As both a BMS and cooling systems provider, we have unique insights that put us in the best possible position to optimise chilled water systems. Complex systems require precise control on a number of levels transforming them into dynamic systems that can adapt and balance themselves, flexing and modulating air and water flow to required loads across the system.

This is why we designed the Cooling System Optimiser, for networked units and for full systems.

Cooling System Optimiser is part of IQity™ Airedale’s IoT-enabled technology framework. Revolutionising how cooling is connected, controlled and automated at critical facilities.
How it works

The optimiser sits above the unit controls and under the BMS, monitoring data from units and field sensors placed at critical points in the system:

• Live water volumetric flow requirement from the CRAHs is used to automatically adjust water flow through the chillers, reducing use of the bypass valves. The optimiser automatically calculates and adjusts the chiller’s pumps speed to achieve the water flow required.
• Ambient temperature is monitored intelligently, optimising free-cooling.
• Flow control over the chillers is balanced to primary / secondary ring monitoring, so the chiller’s pumps speed will adjust to guarantee that the primary flow is always greater than the secondary.
• All data is then fed back to the BMS for indepth monitoring, offering a full picture of the system

KEY BENEFITS

energy-01

Up to 45% Energy Savings

Lower cost of ownership can be achieved, both in running and maintenance costs thanks to the use of latest technologies and full redundancy. Free-cooling is maximised.
maintenance-01

Lower Maintenance Costs

Balanced demand across all units with no fixed leading unit distributes load evenly, avoiding excessive wear and tear. Full redundancy and remote support option leads to fewer call-outs.
max-operating-efficiency-01

Maximum Operating Efficiency

Leveraging the benefits of single-loop water cooling system, the optimiser increases the efficiency of the system by infinitely modulating flow in the chillers and fan demand in the CRACs.
redundancy-01

Full Redundancy

Failover strategy is built into the optimiser, so each controller can smoothly migrate control to the next one, providing redundancy and eliminating the risk of downtime.
standardised-01

Standardised Solution

We provide a standardised solution that suits customers needs, minimising the requirement of tailor-made applications. The off-the-shelf system works with existing unit controllers.
free-cool-01

Free-Cooling

A fully integrated control strategy enables the chillers to operate on a reduced water flow rate during free-cooling operation, sensibly increasing the efficiency of water coils and pumps.
future-proof

Future Proof

Fully compatible with IoT (Internet of Things) and Machine Learning for in-depth analysis.

 OPTIMISE UNITS, OR THE FULL SYSTEM

BC7439revD-chiller

CHILLERS

Chillers have strict requirements for minimum flow to be guaranteed for correct operation when refrigerant-based cooling is active. The Optimiser with its fully integrated control strategy enables chillers to operate on a reduced water flow rate during free-cooling operation, sensibly increasing the efficiency of water coils and pumps.

BC7439-CRAH

CRAHS

The Optimiser networking strategy distributes the cooling demand to all of the operating CRACs to achieve the best energy efficiency, automatically enabling units if required and thermally shifting the load to avoid hotspots, while reducing the energy consumption in the unused areas of the data halls.

BC7439-revD-nolights

FULL SYSTEM

 BMS provider alone wouldn’t be able to achieve the same level of modification or have the same level of protection inside the system as we can achieve if we control everything; By tightly matching the required chiller flow rate to that of the CRAC units, we can make huge savings in pump power.
