Exploration on Energy Saving of Air Conditioning in Data Centers

With the large-scale development of data centers, under the premise of ensu-ring stable operation, reducing the energy consumption of air conditioning systems becomes the primary task to HVAC designers. According to the water-cooled chillers plus natural cooling measures, this paper gives the energy-saving measures for the cold source system. The potential of energy saving from the room humiture and fresh air requirement is ana-lyzed. Combining with the specific project, the paper introduces the energy-saving role of CFD simulation in air distribution. The energy saving control of air conditioning system is expounded from the aspects of sectional loads operation, cold source operating mode switch and precision air conditioning centralized control.
