Redundant climate control system with a mixture of direct and indirect cooling
Air exchangeby enormously efficient equipment generation of Weiss Air Conditioning
Primary cooling by suction and filtration of outside air
Mixing of fresh air with indoor air for a constant temperature level
90% of the hours in a year will not require any mechanical refrigeration, since only external air is filtered and mixed.
9% of the annual hours will only require a small amount of mechanical refrigeration.
1% of the annual hours require mechanical cooling, because the outside air is warmer than the air inside.
Containment of the cold aisles with sliding doors and roofs to avoid mixing effects: The cold air is targeted and used in the exact amount needed. There is no loss, as only the servers are air-conditioned.
