Summary

Data Centres have been developed quickly in recent years. For water cooled data centre cooling system, the freezing of cooling tower in winter is a big problem and very hard to solve. In this paper, a novel system using indirect evaporative chillers to solve the freezing problem is put forward. The running mode and the switch point from refrigeration to free cooling is discussed for the new system. The performance of the recommended system in both winter and summer conditions is analysed both by simulation and by field testing. Upon the results, the ice problem can be solved thoroughly in winter, and the out water temperature of the indirect evaporative chiller can be 6~9K lower than common cooling towers in summer. From a real case study, compared with common water-cooled systems, the free cooling time can be 1000 hours increase and the electricity consumption can be 30~60% reduced.
