SINGAPORE: A new adiabatic-based system designed to deliver powerful pre-cooling for tropical data centres is said to save 20% over conventional chiller systems alone.
Singapore-based ST Engineering’s new Airbitat DC Cooling System is said to enable data centres to reach a targeted PUE of below 1.3, a significant improvement over current regulatory requirements for data centres in Singapore.
Backed by extensive R&D, the Airbitat DC Cooling System comprises a dual coil computer room air handler (CRAH) and a Deep Cooling Unit that’s powered by ST’s patented Reevac Deep Cooling technology. The Airbitat DC Cooling System works by pre-cooling the hot return air in the data hall to reduce over 40% of the heat load from the existing chiller system.
Additionally, the Airbitat DC Cooling System does not generate waste heat into the environment as it does not use compressors, nor refrigerants. It is also said to have lower water consumption requirements compared to conventional water-cooled chiller systems.
The Airbitat DC Cooling System can operate under varied climate conditions ranging from hot and humid, to hot and dry environments. Its smart controls detect ambient psychrometric conditions and automatically adjust its cooling modes in real-time for consistent energy-efficient cooling.
Additionally, its modular design and ability to scale on demand, accommodate different data centre cooling requirements, as well as structural and layout constraints, allows for easy integration in both brownfield and greenfield developments.
“Through re-engineering our established Airbitat solution for the data centre environment, we have successfully developed a sustainable solution that significantly cuts energy consumption while reducing carbon intensity and urban heat island effect. Its ability to be readily deployed in existing data centres presents an attractive option for operators who are looking for cost-effective solutions to lower energy consumption and achieve their sustainability targets,” said Gareth Tang, head of urban environment solutions at ST Engineering.
