Download or read book Advanced Concepts for Renewable Energy Supply of Data Centres written by Jaume Salom and published by CRC Press. This book was released on 2022-09-01 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Refrigeration units in marine vessels written by Prof. Dr.-Ing. A. Hafner and published by Nordic Council of Ministers. This book was released on 2019-04-02 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fishing vessels can be equipped with energy efficient refrigeration technology applying natural working fluids. Ammonia refrigeration systems have been the first choice, but CO2 units have also become increasingly common in the maritime sector in the last few years. When retrofitting or implementing CO2 refrigeration plants, less space on board is required and such units allow good service and maintenance. Nowadays, cruise ship owners prefer CO2 units for the provision refrigeration plants.Ship owners, responsible for the health and safety of the crew and passengers, must carefully evaluate the usage of flammable low GWP working fluids, due to a high risk that toxic decomposition products are formed, even without the presence of an open flame. Suggestions for further work include a Nordic Technology Hub for global marine refrigeration R&D and development support for key components.

Download or read book Design Considerations for Datacom Equipment Centers written by American Society of Heating, Refrigerating and Air-Conditioning Engineers and published by American Society of Heating Refrigerating and Air-Conditioning Engineers. This book was released on 2009-01-01 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of computer rooms and telecommunications facilities is different in fundamental ways from the design of facilities used primarily for human occupancy. ASHRAE has not, until now, published a basic reference text to provide an overview of the special design needs of datacom facilities. As the power density of datacom equipment continues to increase, this need has grown more severe. This book covers basic design considerations for data and communications equipment centers. The book is divided into two parts. Part I, Datacom Facility Basics, includes chapters on datacom design criteria (temperature, temperature rate of change, relative humidity, dew point, and filtration), HVAC load, computer room cooling (including both air and liquid cooling), and air distribution. Part II of the book, Other Considerations, includes chapters on ancillary spaces (battery plants, emergency generator rooms, burn-in rooms and test labs, and spare parts rooms), contamination, acoustical noise emissions, structural and seismic design and testing, fire detection and suppression, commissioning, availability and redundancy, and energy efficiency. This book does not cover electrical or electronic systems design and distribution. The primary changes for this second edition center on the updated thermal envelope and relate to the recommended temperatures at the inlets of the equipment operating in datacom facilities. This book is the third in the ASHRAE Datacom Series, authored by ASHRAE Technical Committee 9.9, Mission Critical Facilities, Technology Spaces and Electronic Equipment. This series provides comprehensive treatment of datacom cooling and related subjects.
