Dr Jon Summers of the University of Leeds Institute of Thermofluids is an expert in thermal management of Data Centres. His talk will cover the measurement and enhancement of Data Centre performance, including advancements in design such as heat sinks, aisle containment, direct liquid-cooling.

Dr Lewis Brown, Star Refrigeration. Lewis will focus on cooling reliability, efficiency and environmental friendly refrigerant choice. He will outline what is happening with HFC refrigerants and the likely next generation of low GWP alternative refrigerants including the new HFO substances. He will also provide a summary of the new EcoDesign directive. The talk will give a series of recent case studies using ammonia chillers for data centre cooling.

George Hannah, Technical Director Airedale Air Conditioning will explore the topic of how much liquid cooling can contribute to Energy Reuse Effectiveness (ERE). What is the proper metric for taking this into account, and how might heat recovery reveal itself in an improved version of PUE? George will discuss these questions and review the different methods of making the best use of the heat reclaimed.
