  • An array of fans pulls in the air and pushes it towards the filters. These fans are able to move large quantities of air but at an extremely slow speed (1m to 1.5m per second), which contributes to the efficiency of the whole cooling system.

    "We could not forget any detail. The two biggest server rooms are 1,000 m2 each and need 10MW of power that becomes heat. In order to cool them we had to build the flues in a certain way — the right way," Mazzarelli said.

  • Once filtered the air is ready to do its job: cooling the servers, which is easier said than done if you are determined to do it efficiently. "Then again, you don't want to waste an inch of air, so to speak," Mazzarelli joked. That means, he said, sending the air where it is most needed: in front of the servers rather then behind them.

  • Having been heated and pushed out by the servers, the hot air rises and exits the facility through the flues' holes. "The result of this design is that inside the cage, where you need it, you have a temperature around 25C, while outside it's 35C," Mazzarelli said. "Once out of the cage, the hot air now can go outside because of the Stack effect."

    How exactly supply air is cooled to desired 25°С? Do they use chillers / freon air conditioners and mixing chambers for that purpose? And what about humidity? Ferrera Erbognone is located close to the sea – so there should always be enough moisture. But, in winter the humidity will hover around 100%. So how exactly is it controlled? I thought of dehumidifiers, but they are too energy intensive – not good for PUE.
