Heat recovery has emerged as a key strategy for improving sustainability and operational efficiency as global data centre energy consumption rises. In this session, we will explore the evolving regulatory landscape, technical challenges, and practical solutions for utilising waste heat from data centres. We will also address various heat recovery configurations and analyse the role of chillers, heat pumps, and hybrid cooling systems in optimising energy efficiency. Finally, the session will highlight Daikin’s cutting-edge solutions that enable effective heat reuse, reduce environmental impact, and enhance overall system performance.
