  • FIG. 15 shows an embodiment of a data centre 100, comprising a plurality of data centre racks 1 according to the invention that comprises a data centre cooling system for these data centre racks 1 that makes use of outside air.
  • air-side economizers 92 are arranged where the outside air is brought into the data centre 100 and distributed via a series of dampers and fans. Instead of being re-circulated and cooled, the heated air coming out the rooms with data centre racks 1 installed is simply directed outside through the data centre tube system 82.
  • the economizer 92 may mix the heated air and the incoming air, ensuring that the resulting air temperature falls within the desired range for the data centre racksl
  • the Air-Side economizers 92 preferably include filters to reduce the amount of particulate matter or contaminants that are brought into the data center 100 and regulates the humidity of the air.
