A datacentre located in Bern-Wankdorf and owned and operated by Swiss telco, Swisscom has been awarded the energy prize 'Watt d'Or' in the category 'Renewable energies' by a jury under the patronage of the Swiss Federal Office for Energy.
The jury said the datacentre is one of the most secure, modern and energy-efficient such facilities in Europe. Only outside air and rainwater is used for cooling. The operator has also abandoned the use of polluting refrigerants, and feeds its waste heat into the city council's new heating network.
Last summer, the Bern-Wankdorf facility was awarded Tier IV Design Certification by the Uptime Institute.
Euro-Diesel a terminé avec succès la mise en service de 4 systèmes de 2000 kVA qu'elle a livrés à SWISSCOM Immo pour son tout nouveau data centre.
Em 5 de agosto, São Paulo sediou o Data Center Infra São Paulo, evento que reúne conferência e área de exposição e objetiva reunir os principais profissionais da área e as novas tecnologias, disponibilizando informações e conhecimentos sobre construção, renovação e operação de data center. [PDF][+]
The NO-BREAK E1 is such a simple concept that one might think of it as a conventional generator-set. It is made up of a Diesel Engine separated/coupled to a Stato-Alternator, via an Electromagnetic Clutch. The Stato-Alternator is the combination of the Kinetic Energy Accumulator and a Synchronous Machine.
The NO-BREAK E1 also includes a control panel and a choke/power panel.
Description of the Stato- Alternator
The heart of the NO-BREAK E1 is the kinetic energy accumulator; a clever but simple system to store and retrieve kinetic energy.
How does it work? - Energy storage
In conditioning mode, the drive shaft is spinning at 1800rpm, and the AC winding is powered to generate a rotating magnetic field which turns the drum to the maximum speed of 3000 rpm.
How does it work? -Energy retrieval
When a utility outage occures at the input of the system, the DC winding of the inner rotor is energized and the outer drum is electrically coupled to the inner rotor by an induced field. The kinetic energy of the drum then "drives" the inner rotor via this induced field. This energy transfer is regulated by accurately controlling the current injected into the DC winding ALWAYS maintaining the output frequency to 60Hz.
