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 KS® is such a simple piece of equipment that one might think of it as a conventional generator-set. It is made up of a Diesel Engine that is coupled to a Stato-Alternator, via an Electromagnetic Clutch. The Stato-Alternator is the combination of a Kinetic Energy Accumulator and a Synchronous machine.
The NO-BREAK KS® also includes a control panel and a choke/power panel.
How does it work?
In the heart of the NO-BREAK KS®‚ is its kinetic energy accumulator; a clever but simple system to store and retrieve kinetic energy.
In conditioning mode, the AC winding is powered to generate a rotating magnetic field which turns the outer rotor to the speed of maximum 3000 rpm. However, the relative speed between inner and outer ring of the bearings is only 1500 rpm, since the shaft itself is rotating at 1500 rpm.
In independent mode, the DC winding is powered and the outer rotor is electrically coupled to the inner rotor by induction. Its kinetic energy is transferred to the inner rotor -- it drives it. This energy transfer is regulated by accurately controlling the current injected into the DC winding.
