Data Centre Cooling
446 articles 11 insights
Data centre cooling has become a refrigeration problem at industrial scale: rack densities that air alone cannot hold, liquid and immersion systems moving from pilots into production, and heat rejection that neighbouring buildings now want back. Refindustry follows what is actually being installed: daily news, case studies with the figures their owners reported, and the engineers designing these systems.

Data Center Cooling: The Site Decides the System, the Operator Decides the Refrigerant
The first part of this series traced a chain of decisions from public data and disclosed projects: what a site can supply in power, water, and demand for waste heat sets the cooling architecture, and the architecture narrows the refrigerant. This part puts that chain to six people who build and supply the equipment. The
Chillventa 2026 Preview: Key Technologies Ahead of the October Show
Exhibitors arriving in Nuremberg on 13 to 15 October are no longer arguing about whether to move to natural refrigerants. They are showing how fast the move can be made, and at what cost. That single change of question runs through nearly every release we have received ahead of Chillventa 2026, the largest edition of
Power, Water, and Heat: How Site Resources Now Decide the Refrigerant in a Data Center
For an engineer reading a data center brief in 2026, the first constraint is rarely the heat load. It is whether the site has the electricity, the water, and a use for the rejected heat to run a given cooling scheme at all. The cooling technology, and with it the refrigerant, follows from what the
