COMPARISON OF EFFICIENCY AND COSTS BETWEEN THREE CONCEPTS FOR DATA-CENTRE HEAT DISSIPATION
■Information technology and telecommunications (ITC) is a significant factor in modern economies. In Germany alone, gross value added has increased in this sector by nearly 50 per cent since the mid-1990s and is now larger than the automotive industry and engineering. There is however a downside: the energy consumption of the roughly 50,000 server rooms and data centres in Germany in 2008 was some 10.1 TWh, more than double the figure for 2000. Accordingly, in 2008 German data centres were the cause of almost 6.4 million tonnes of CO2emissions.
■Worldwide, commercial IT generates about 2 % of CO2 emissions, roughly equal to that generated by aviation. It can thus be seen that energy efficiency must play an increasingly important role, from both economic and environmental perspectives.
■This paper examines three concepts for data centre heat dissipation. On the basis of values obtained from experience we examine and compare the advantages, disadvantages, average investment costs and running costs of the three concepts for a data centre with an assumed 300 kW power dissipation.
