COOLING

Direct and Free Cooling

• Optimum temperature and humidity are maintained in the server rooms.
• We use Emerson and Stulz air conditioning units for direct cooling.
• Each data hall contains a set of units in redundancy N + 2.
• The electrical switchboard room and the UPS room are cooled by a separate set of units in redundancy N + 1.
• The datacentre has a total of 12 air conditioning units.
• Free Cooling is a cooling system that uses cool outside air. It is installed in server room B, the electrical control room and the UPS room.
• The Free Cooling system can be used up to an outdoor temperature of 16-18 °C.
• All data centre air conditioning equipment is connected to back-up power circuits.

Cold aisles

• Both data halls use a cold aisle system for more efficient cooling.
• Cool air from the air conditioning units is fed through the double floor into cold aisles directly to the servers.
• The heated air from the servers flows into the server room so that it does not mix with the incoming cold air.
