Diagnosis and Renovation on Cooling System for Energy Saving in Small and Medium-sized Data Centers
The high energy consumption of small and medium-sized inventory data centers is focused in this paper.With survey and analysis for energy-saving diagnosis,it's the main aspects of the cooling system architecture,humidity control,design and operation under low ambient temperature,free cooling,performance decrease for long term operation.Then the performance improvement is discussed from the main components such as compressor and heat exchanger,and the cooling system architecture such as the indoor terminals,water-cooled chiller system,direct-expansion refrigeration system,distribution system.At last,the energy-saving transformation technology schemes are proposed as the humidity control,free cooling,evaporative cooling,intelligent control.The above provides reference for energy-saving transformation of inventory data centers.
