Carrier develops CO₂ product for data centre cooling

Designed specifically for data cooling, Carrier’s Data CO₂MPLETE is a hybrid system that combines water with the natural refrigerant CO₂ to provide a cooling capacity of 250 kW per system.

The cooling racks are equipped with EC motors with variable speed drives and with precision control. They are installed directly on top of data servers, allowing highly efficient heat rejection.

Heat is absorbed by the cooling systems and discharged via the CO₂ circuit and water-cooled condensing units. A separate cold-water circuit cools the condensing units. This configuration keeps the water out of the cooled space itself, which is particularly important in data cooling centres.

Data CO₂MPLETE, including its liquid chillers and building management systems, is entirely compatible with all other products from Carrier’s portfolio

“With the new products, we are now in a position to deliver a full package including cooling, regulation technology and service, to cater to the high requirements in data centres,” said Teddy Kunicic, product and system design manager at Carrier.
