Free Cooling Potential of Turkey for Datacenters

Cooling electricity consumption in data centers is increasing rapidly. The heat released from equipment’s in datacenters is discharged into the room and room has to be kept at acceptable temperatures. To reduce the electricity consumption for cooling in cold regions, free cooling technology is more efficient instead of conventional systems. It is favorable to know the free cooling potential of a location before the installation of free cooling system. In this study free cooling potential of Turkey is investigated according to supply air temperatures from 15 °C to 21 °C for six cities Ankara, Antalya, ？zmir, Erzurum, Konya and Trabzon respectively. Then Power Usage Effectiveness (PUE) value of a datacenter with a free cooling chiller is calculated for each city by using the electricity consumption measurements of cabinets conducted in a datacenter in Ankara, Turkey. Calculations show that free cooling system is convenient for Erzurum, Ankara and Konya with PUE values 1.23, 1.37 and 1.37
