Cooling system
This picture, looking down through a glass cutaway, shows the water-supply pipes for part of the cooling system. In the top right-hand corner of the picture is the cage for a fan that circulates conditioned air under the floor. Outside air can be filtered to extract dust and particles and mixed with air-conditioned air inside, but the data-center unit is usually sealed, and air inside filtered and recirculated.
