Summary

Johnson Controls has published an Absorption Chiller Reference Design Guide for data centre operators running on-site power generation, where 57% of the energy produced is typically lost as waste heat. 

The blueprint sets out how that heat can be routed into cooling rather than dissipated, cutting cooling-related electrical demand by up to 44% and freeing capacity for compute. 

In a 1GW AI Factory, the company calculates that those gains support up to 97MW of additional AI computing capacity with no increase in on-site generation.

“Johnson Controls helps transform recovered heat into useful work through Combined Heat and Power and absorption cooling solutions, enabling AI Factories to scale more efficiently while reducing strain on the grid and delivering value to local communities.”
