Thermal Control Update
Summary
A new absorption chiller blueprint enables data centres to convert waste heat into cooling, cutting cooling electricity demand by up to 44%. The modular design boosts computing capacity using existing power infrastructure, supports a PUE as low as 1.23, eliminates on-site water use, reduces cooling system CO₂ emissions by up to 43%, and accelerates AI data centre deployment from 100MW campuses to gigawatt-scale facilities.
Johnson Controls launched its Absorption Chiller Reference Design Guide. The blueprint helps data centre operators convert the 57% of energy typically lost as waste heat from on-site power generation into productive cooling, reducing cooling-related electric demand and allocating more power available for AI workloads. In a 1GW-scale AI Factory, those efficiency gains can support up to 97MW of additional AI computing capacity without increasing on-site power generation, creating the potential for up to $18 billion in additional revenue over the life of the facility, based on a typical U.S. AI Factory model.
