Other AbstractThe high energy consumption of data center presents a major barrier to the development of information industry,while the utilization of natural cold sources is very important to realize energysaving and consumption-reduction.This paper mainly studies the utilization of natural cold sources in data center.The recommended values of the critical wet bulb temperature of natural cold sources under evaporative cooling conditions are determined.The utilizing potential of natural cold source in major climate regions of China is analyzed in detail.Moreover,the concept of natural cold source sensitivity is introduced.In addition,a typical data center in hot summer and warm winter zone is taken as an example to analyze the energy-saving effect of natural sold sources.The result indicates that natural cold source utilizing ratio in data centers exceeds 50% in most regions at a critical wet bulb temperature of 16 ℃.However,the temperate region had the highest sensitivity concerning the natural cold source.Annual comprehensive COP value of data centers increases by 23.7%,and the energy saving rate is about 19.2% when using natural cold sources in hot summer and warm winter zone.
