Today’s data centre managers are facing increased financial and regulatory pressure to improve the efficiency of their data centres. At the same time, the IT environment is changing – loads are more dynamic – making a flexible, more predictable physical infrastructure a necessity. Traditional cooling approaches are inadequate to address these challenges.

A new white paper published by Schneider Electric’s Data Center Science Center describes a new approach to data centre cooling that uses approximately half the energy of traditional cooling architectures, but at the same time provides greater scalability, availability, and ease of maintenance.

In order to achieve aggressive PUE targets, data centre managers must adopt a cooling philosophy in which the primary mode of operation is on economizer, whilst the mechanical system provides a back-up to the economizer when needed.

White Paper 136: “High Efficiency Economizer-based Cooling Modules for Large Data Centers” examines the pro’s and con’s of two common approaches to fresh air cooling – direct and indirect of use of fresh air in the IT space. The latter method is more commonly accepted by data centre operators today and there are several ways of implementing indirect fresh air cooling which are largely distinguished by how many heat exchanges occur between the indoor air and outdoor air.

For a significant number of climates around the globe, an indirect evaporative cooling system with air-to-air heat exchange is the most effective way to achieve economizer-based cooling, without directly exposing the IT space to airborne contaminants and outside air conditions.

Another Schneider Electric White Paper (132), Economizer Modes of Data Center Cooling Systems, compares the economizer modes best suited for data centres, suggesting a self-contained cooling system using design principles which can reduce energy consumption by 50% whilst still offering the flexibility and scalability needed for large data centres.

The proposed cooling architecture can adapt effectively to varying IT loads, be scaled quickly as capacity is needed, and is constructed using standardized and pre-engineered components with integrated controls for optimal operation. This, together with best practice airflow management and a wider operating window for IT temperature, enables cooling capex and opex to be reduced substantially.
