| The interior of a hot hut row |
The black circles along the walls in the photograph above are the exhaust fans on our server trays, and the hoses coming up from the floor contain water going to and from the cooling coils in the top of each unit. Fans on top of each Hot Hut pull hot air across these water-filled cooling coils. This cooled air leaving the Hot Hut returns to the ambient air in the data center, and machines can draw in this air again to cool themselves down, completing the cooling cycle.

We chose a water-based cooling system for our data centers
since water can hold more heat than air. Water-based cooling means running pipes under the raised floors in our data centers. With so much electrical equipment in place, we take precautions with regular inspections and an alarm system which detects leaks. Here, a data center technician inspects underfloor water pipes which lead to a heat exchanger in the cooling plant.
