LuxConnect built a data and communication center with a data center area of 2,592 m² and 126 m² carrier area from 2007 to 2009. For companies that process sensitive and readily available data, the center was designed with high availability. The power supply, cabling up to the rack, air conditioning of the data center area and the central rooms for the infrastructure are therefore doubly designed for the performance required in each case.
A TIER IV standard was implemented, i.e. a 2n system in which the cooling and power supply system is designed in such a way that both systems are actively trained. The dual systems and supply paths are separated from each other in such a consistent manner that if a fault occurs, the second system is prevented from being affected. Both systems simultaneously supply computer equipment. In addition, each UPS system is single redundant. According to the calculation, there was a necessary cooling requirement of approximately 3,600 kW for the server, carrier and UPS rooms. The cooling is supplied by electrically driven compression chillers with screw compressors. Due to building regulations, ammonia is used as the refrigerant. Thus, four compression chillers with a capacity of 1,700 kW each were installed. The generation plant is decoupled from the transmission by means of a hydraulic separator of 2 x 20,000 l. Recirculating air cooling units are used in the technical areas of the server areas. The heat supply of the building is provided by a heat pump system. The heating capacity is 105 kW. The cooling water circuit of the chillers serves as the heat source. In the case of free cooling (winter), a return temperature of 15°C is available.
The control takes place via the DDC/BMS system. According to the power balance this results in an electrical building peak power of 6,100 kVA, which is designed with redundancy. For this purpose, 2 dry-type transformers with 3,150 kVA each are used on each supply side. For the uninterruptible power supply of the data center, the UPS power is 1,438 VA per m², and the total power is 3,900 kVA. This is ensured by the use of static UPS systems, with 4 x 500 kVA systems +1 being used per UPS block. The bridging time of the batteries is 10 minutes. Mains emergency generators (emergency power supply) with parallel synchronization are installed as a self-power supply system. According to the power balance, emergency diesel generators planned for the backup power supply will be designed for a capacity of 4x 1,640 kVA (variable continuous power) per supply side.
