Stockage d'énergie thermique en aquifère (ATES)
The ATES system at Equinix's AM3 IBX in Amsterdam uses cold groundwater to help chill air on the colocation floor, eliminating the need for traditional mechanical cooling. When temperatures rise above 18 degrees Celsius (64 degrees Fahrenheit), the ATES system kicks in to keep equipment cool. At other times of the year, AM3 relies on free-air cooling. Excess heat generated by customer's IT equipment is also used to help warm nearby buildings.
