Low-energy cooling for computer centres

GEA, data centre cooling, computer centre

Computer-centre cooling units that combine indirect free cooling with adiabatic humidification from GEA offer an airflow of 25 000 m3/h with a cooling duty of 100 kW. The extremely low operating costs of the Adia-Denco cooling system enable its amortisation after a short period.

The system is designed to satisfy the latest environmental recommendations for computer centres, which advise maximum supply-air temperatures of 27°C.

With an outdoor temperature under 6°C, indirect free cooling alone can extract the thermal load produced — without support from additional cooling sources. Highly efficient EC fans in the outside airflow operate at minimum speed and ensure that the temperature of the supply air for the computer centre does not exceed 25°C. At higher outdoor temperatures, the speed of the EC fans increases. It is only above 22°C that adiabatic cooling is required.

Depending on the output demand from the computer centre and at outdoor temperatures over 29°C, adiabatic cooling is support by an additional peak-load cooler.
