The rapid increase of cloud computing, high performance computing
(HPC) and the vast growth in Internet and Social Media use have
aroused the interest in energy consumption and the carbon footprint
of Data Centres. Data Centres primarily contain electronic
equipment used for data processing (servers), data storage (storage
equipment), and communications (network equipment). Collectively,
this equipment processes, stores, and transmits digital information
and is known as information technology (IT) equipment. Advanced
Concepts for Renewable Energy Supply of Data Centres introduces a
number of technical solutions for the supply of power and cooling
energy into Data Centres with enhanced utilisation of renewable
energy sources in order to achieve low energy Data Centres. Because
of the high energy density nature of these unique infrastructures,
it is essential to implement energy efficiency measures and reduce
consumption before introducing any renewable energy source. A
holistic approach is used with the objective of integrating many
technical solutions such as management of the IT (Information
Technology) load, efficient electrical supply to the IT systems,
Low-Ex air-conditioning systems, interaction with district heating
and cooling networks, re-use of heat, free cooling (air, seawater,
groundwater), optimal use of heat and cold storage, electrical
storage and integration in smart grids. This book is therefore a
catalogue of advanced technical concepts that could be integrated
into Data Centres portfolio in order to increase the overall
efficiency and the share of renewable energies in power and cooling
supply. Based on dynamic energy models implemented in TRNSYS some
concepts are deeply evaluated through yearly simulations. The
results of the simulation are illustrated with Sankey charts, where
the energy flows per year within the subsystems of each concept for
a selected scenario are shown, and graphs showing the results of
parametric analysis. A set of environmental metrics (as the
non-renewable primary energy) and financial metrics (CAPEX and
OPEX) as well of energy efficiency metrics like the well-known PUE,
are described and used to evaluate the different technical
concepts.
