Climate control in the data centre

A common cooling method for data centres is direct, free outdoor cooling. In this case, the warm exhaust air from the IT systems is discharged to the outside via the air-conditioning systems, and fresh outside air is fed into the data centre for cooling. This saves the data centre operator several thousand hours of compressor cooling, which results in energy savings of up to 90% compared to classic recirculating air coolers with compressors. Other techniques used in data centres are cooling with water or the use of evaporative cooling. One form of this is the technical implementation in adiabatic cooling. For air conditioning in data centres, adiabatic cooling is significantly more efficient and energy-saving than conventional air cooling. In addition, it is possible to cool indirectly by means of air-to-air heat exchangers without the use of adiabatic processes.

Depending on the customer’s requirements and the local conditions, CADOLTO DATACENTER selects the optimal and most economical solution in close consultation with the customer – of course always with sustainability in mind.

To ensure smooth operation of the IT infrastructure and at the same time achieve the highest possible level of energy efficiency, a supply air temperature of 25 °C to 27 °C is optimal. Here, every degree higher supply air temperature saves between 3% and 5% energy in cooling.
