At present, around 50000 data centers exist in Germany with an annual electricity demand of 10 TWh. About 50 % of the demand is needed for infrastructual purposes only, like cooling, lighting or the uninterrupted power supply, where the electricity demand for the cooling makes about 25 %.

To reduce this high electricity demand for cooling, a wide range of applications are considered to be implemented:

  • The use of indirect, free cooling with adiabatic evaporative cooling
  • Reducing the system resistance for efficient air transportation
  • Effective cooling of the IT-components (Server and UPS)
  • Cold Aisle Containment for a homogenous air flow and prevention of backflow (air-tightness of containment)
  • Targeted air flow to prevent hotspots
  • Efficient air flow control via differential pressure sensors and velocity anemometry between cold- and hot aisle

The overall objective of this project is to demonstrate a data center which is cooled with a SPF = 100 (annual mean pPUE = 1.01), which means 100 kW of IT waste heat is removed by 1 kW of cooling power, without the need of compression refrigeration. In a first laboratory phase, the system is build, tested, iteratively improved and evaluated at the Hermann-Rietschel-Institut. The results of the laboratory phase are then transferred into a newly constructed real data center at the university of Greifswald. A field test and annual monitoring will be conducted to prove the systems efficiency.
